10) Which preparation produces a 2.0 M solution of Co
H1206? [molecular mass = 180.0]
(A) 180.0 g of C6H12O6 dissolved in 1000. mL of
solution
(B) 90.0 g of C6H1206 dissolved in 1000. mL of
solution
(C) 180.0 g of C6H1206 dissolved in 500.0 mL of
solution
(D) 90.0 g of C6H1206 dissolved in 500.0 mL of
solution

Answers

Answer:

(C) 180.0 g of C6H12O6 dissolved in 500.0 mL of solution

Explanation:

Molarity is mole/volume.

1. Find the mass of C6H12O6 in 1 Liter of 2.0 solution

(2 mol C6H12O6 / L) * (180 g / mol C6H12O6) = 360 g C6H12O6

There are 360 g C6H12O6 in 1000 mL of solution

2. Compare the value you found in step 1 to each of the multiple choice answers.

180.0 g of C6H12O6 dissolved in 500.0 mL of solution is exactly proportional to 360 g C6H12O6 in 1000 mL of solution.

The preparation which produces a 2.0 M solution of C₆H₁₂O₆ is 180.0 g of C₆H₁₂O₆ dissolved in 500.0 mL of solution.

How molarity is calculated?

Molarity is defined as the number of moles of solute present in per liter of solution.

Moles of any substance will be calculated as :

n = W/M, where

W = given mass

M = molar mass

In the question given that molar mass of C₆H₁₂O₆ is 180 g/mole, and let we have produced the solution of 2 molarity by these amount in 1 liter i.e.

2 = n/1

n = 2 moles

Now by using these moles we can calculate the required mass of C₆H₁₂O₆ as:
2 = W/180

W = 360g

From this it is clear that for the preparation of 1 liter of solution of 2 molarity 360g of C₆H₁₂O₆ is required. So in 500mL of solution, 180 g of C₆H₁₂O₆ will use.

Hence, option (C) is correct i.e. 180.0 g of C₆H₁₂O₆ dissolved in 500.0 mL of solution.

For which substance is the standard heat of formation not equal to zero?

Hydrogen (H2)

Aluminum oxide (Al2O3)

Oxygen (O2)

Potassium (K)

Answers

Answer:

Aluminum oxide (Al₂O₃)

Explanation:

The standard heat (or enthalpy) of formation of a compound, is the amount of change in the enthalpy that takes place when 1 mole of the compound is produced from the elements it contains whereby the compounds and elements in the reaction are in their standard states

The standard state of an element, is the state in which the element is in the most stable form at a pressure of 1 bar

Therefore, the heat of formation of hydrogen, H₂, oxygen, O₂, and potassium, (K), will have a heat of formation of zero, while Al₂O₃ which is made of aluminum and oxygen in combining to form a compound in proportions which are different from their initial standard states will have a heat of formation not equal to zero

An element with high conductivity would be found in which
category?
Alkaline earth metals
transition metals
Group 1 metal
Alkali metals
***Why would you not pick the others?

Answers

You would choose The group 1 metals in this case.(aka your alkali metals)

Explanation:Looking at the periodic table it takes them 1 electron to give away to achieve stability which tells me they are by far the “smoothest” and “free moving” metals.Making it much more easier for electrons to be carried from one end to the other in its molten state.Because of how easy the electrons get to move from one end to the other,the currents are faster. (the easier the electrons move the better the conductivity)

Why are the other type of metals not really a good conductivity when compared to Group 1 Alkali metals?
Answer:Transition metals don’t really have a specific charge so it depends.Because of this it doesn’t determine how good it’s conductivity is because you don’t know what’s being lose unless it’s stated.And transitioning from metals to non-metals makes the property lean nearer to the non-metals which is not a good electrical conductivity.Furthermore,for alkaline earth metals it takes 2 charges to transfer to achieve stability which is not as smooth as group 1 metals,making it less as great in terms of conductivity.At the end of the day they all conduct electricity as they’re all metals.But it varies on how great they are which depends on their charges.

Calculate how many grams of sodium chloride we would need to make a solution with the same molarity of seawater, which is about 0.598 M.

Answers

Answer:

34.92 grams NaCl (in 1 L of solution)

Explanation:

The chemical formula of sodium chloride is NaCl. From the formula, we can calculate the molar mass of NaCl:

MM(NaCl)= MM(Na) + MM(Cl) = 23 g/mol + 35.4 g/mol = 58.4 g/mol

A solution of NaCl with a molarity of 0.598 M has 0.598 moles of NaCl per liter of solution. So, we multiply the moles by the molar mass of NaCl to calculate the mass we need:

mass of NaCl = 0.598 mol x 58.4 g/mol = 34.92 g NaCl

Therefore, we need 34.92 grams of NaCl to prepare 1 liter of a solution with a molarity of 0.598 M.

Methane, a highly flammable gas, is placed in a piston that has a volume of 2.1
L at STP. The piston then compresses the gas to 125 mL. What is the pressure
inside of the piston?

Answers

Use the formula:
P1V1/T1N1 = P2V2/T2N2
You can cross out T1,N1,T2, and N2 because you are working with pressure and volume in this equation.
Now, you are left with Boyle’s Law:
P1V1 = P2V2
Substitute the values in
STP = 1 atm for pressure
(1 atm)(2.1L) = P2 (0.125 L) [I converted 125 ml to liters so they would be the same unit]
Now, divide both sides by 0.125 to find P2
P2 = (1 atm)(2.1 L)/(0.125 L)
Liters cancel out
P2 = 16.8 atm

Two reasons that a plant from a rain forest would not survive in a desert home?

Answers

Answer: A planet from a rain forest would not survive in a desert home, for the fact they depend on water and as these live from water, without it, this leads to dehydration and with loss of water with plants, nothing is able to survive when it comes to a rain forest plant being in a desert home. Another reason is the high trees and leaves that are providing the plants enough sunlight or shade to grow, it guarantees to help keep the temperature normal. Being in a deserted area would mean that there would be a temperature change, something the plant is not used to. Without that needed shade and avoiding the scorching sun, they will die out from how different the temperature is, and how hot it is.

Explanation: I hope this helped you.

okay, the answer should be simple and easy, plants from a rainforest would not survive in a desert because the plants in the rainforest do get water, sunlight and air whereas the plants in the desert have Sunlight which is very hot. so if a plant in the rainforest was transferred to the desert it will hard to survive and it will eventually die because they will not get water that will be needed and the plant can get sunburns with the too hot temperature.

Whilst Et₃CCl is unreactive towards water even at elevated temperatures, Et₃SiCl is hydrolyzed rapidly. Explain the origin of these differences and provide a reaction scheme with mechanistic details for the hydrolysis of Et₃SiCl.

Answers

Answer:

See Explanation

Explanation:

In discussing the reason why Et₃SiCl is more easily hydrolysed than Et₃CCl, we must remember that the electronegativity difference between silicon and chlorine is much higher than the electronegativity difference between carbon and chlorine.

As a result of this, the Si-Cl bond in Et₃SiCl is more polar and hence susceptible to attack by water than the C-Cl bond in Et₃CCl.

Also, it is postulated that the presence of vacant d orbitals on silicon assists hydrolysis in Et₃SiCl. Such vacant orbitals are absent in carbon hence Et₃CCl does not undergo hydrolysis.

Agustina was standing on the edge of a cliff of unknown height holding a bowling ball. She wanted to find the height of the cliff. She worked with Maite to time the how long the bowling took to fall to the bottom of the cliff. Maite timed the drop at 9.4 seconds on each of their 10 trials. The bowling ball started at rest on each of the trials. What distance did the bowling ball fall in each trial?

Answers

Answer:

433 m

Explanation:

Since the fall represents motion under gravity, we use the equation

s = ut - 1/2gt² where s = height of cliff or distance bowling ball falls through, u = initial velocity of bowling ball = 0 m/s(since it starts from rest), t = time = 9.4 s and g = acceleration due to gravity = -9.8 m/s².

So, substituting the values of the variables into the equation, we have

s = 0 m/s × 9.4 s - 1/2 × 9.8 m/s² × (9.4 s)²

s = 0 m - 1/2 × -9.8 m/s² × 88.36 s²

s = 1/2(865.928 m)

s = 432.964

s ≅ 433 m

Answers

Answer:

1. Allele for shortness (t)

2. Allele for tallness (T)

Explanation:

Gregor Mendel performed numerous experiments using pea plants (Pisium sativum). He tested the height traits of pea plants by crossing tall pea plants (TT) and short pea plants (tt) to obtain offsprings that were all tall (Tt) in the first filial generation (F1).

This is possible because the allele for tallness is DOMINANT while the allele for shortness is RECESSIVE. This means that tallness allele (T) will mask the phenotypic expression of shortness allele (t) when in an heterozygous state (Tt) as in the F1 generation.

Answers

Answer:

d. Two moles of carbon dioxide were produced from this reaction

Explanation:

The given chemical reaction can be written as follows;

2C₂H₂ + 5O₂ → 4CO₂ + 2H₂O

From the above chemical reaction, we have;

Two moles of C₂H₂ reacts with five moles of O₂ to produce four moles of CO₂ and two moles of H₂O

We have;

One mole of C₂H₂ will react with two and half moles of O₂ to produce two moles of CO₂ and one mole of H₂O

Therefore, in the above reaction, when one mole of C₂H₂ is used, two moles of CO₂ will be produced.

Structures and Forces - What is force and external forces.

Question 1) Jacob and Ravleen are moving furniture. They need to move the filing cabinet over 6 feet and it is very heavy. Jacob wants to apply force and push it by putting his hands on point A because he thinks it would be easier to move it from the top as there is less weight on the top. Ravleen says it's better to push at point B because the center of gravity is lower. Which person is correct and EXPLAIN why and what may happen if it is pushed in the wrong spot.

Answers

Answer:

The restoring force that prevents the furniture from tipping over when pushing the furniture towards the right, F= W × D

Where;

W = The weight of the furniture

D = The horizontal distance from the center of gravity of the furniture, CG and the to the lower right corner of the furniture

Given that A > D, for the furniture to tip over when pushing above the CG, we have;

F1 × A ≤ W × D

∴ F1 << W or for a force much smaller than W, the weight of the furniture applied above the center of gravity, the furniture will tip over

However when the force F2 is applied, where C < D, we have for no tipping over;

F2 × C ≤ W × D, therefore, given that C < D, when a force much higher than the weight, W, is applied at F2, the furniture will remain upright

Therefore, it is better push at a point lower than or equal to the center of gravity, whereby the point B is lower than the center of gravity, it is better to push at point B, Ravleen is correct and it is better to push at point B because the center of gravity is lower

If the furniture is pushed at the wrong spot it may tip over
