A chemistry student conducted several different procedures. Which of the following procedures best demonstrates the law of conservation of mass?
O using filter paper to separate 2 grams of solid powder from 10 grams of water
O burning 2 kilograms of wood from a pine tree leaves 0.4 kilogram of ash and soot
O evaporating sugar water leaves 5 grams of sugar and turns the water into water vapor
O combining 2 grams of copper and 4 grams of sulfur to make 6 grams of copper sulfate

Answers

Answer:

combining 2 grams of copper and 4 grams of sulfur to make 6 grams of copper sulfate

Explanation:

The Law of Conservation of Mass states that matter cannot be created or destroyed in chemical reactions. It posits that the mass of a substance remains unchanged after undergoing a chemical process.

Therefore, according to the question, the procedure that best demonstrates the law of conservation of mass after the chemistry student conducted different procedures is option D.

This is because, the mass of copper and sulfate did not change but merely combined to form a compound.

B. LZAQD

A. Younger than A but older than Q

Explanation:

To solve this problem, we simply apply the stratigraphic laws which are the law of superposition and principle of cross cutting.

According to the law of superposition, in an undeformed sequence of strata, the oldest layer is always at the bottom and the youngest on top. In this case, we have a little disturbance but it did not affect much of the original bedding. So, the rock ages from L to Z to A to Q and D. L is the oldest and D is the youngest.

According to the principle of cross-cutting "features that cuts through a rock are younger than the layers they cut through". In this problem, the fault cuts through layers LZ and A which suggests that these layers are older than the faulting event. Layer Q is unaffected by the faulting so, the fault is older than the layer.

A competitive high school swimmer takes 56.7 seconds to swim 100. yards. What is his rate in m/min?

m

min

Answers

Answer:

96.72 m/min

Explanation:

The following data were obtained from the question:

Time (t) = 56.7 s

Distance (d) = 100 yard

Rate (R) =?

Next, we shall convert 56.7 s to minutes. This can be obtained as follow:

60 s = 1 min

Therefore,

56.7 s = 56.7 s × 1 min /60 s

56.7 s = 0.945 min

Next, we shall convert 100 yard to metre (m). This can be obtained as follow:

1 yard = 0.914 m

Therefore,

100 yard = 100 yard × 0.914 m /1 yard

100 yard = 91.4 m

Finally, we shall determine the rate of the swimmer as follow:

Time (t) = 0.945 min

Distance (d) = 91.4 m

Rate (R) =?

R = d/t

R = 91.4/0.945

R = 96.72 m/min

Thus the rate of the swimmer is 96.72 m/min

Answers

Answer:

See image attached

Explanation:

The reaction of toluene with alkaline potassium permanganate in the presence of heat leads to the oxidation of the -CH3 to give benzoic acid.

Reaction benzoic acid with HNO3/H2SO4 yields the nitronium ion (NO2+).

Recall that -COOH is a metal director and deactivated the ring towards electrophilic substitution hence the m-nitrobenzoic acid is formed.

Given the solution containing HCl, the solution is likely to have a low pH and a high poH

What is pH ?

This is simply a measure of the acidity / alkalinity of a solution.

The pH measures the hydrogen ion concentration while the pOH measures the hydroxide ion concentration

pH scale

The pH scale is a scale that gives an understanding of the variation of the acidity / alkalinity of a solution.

The scale ranges from 0 to 14 indicating:

0 to 6 indicates acid 7 indicates neutral 8 to 14 indicate basic

However, it should be noted that as the pH increases, pOH decreases and as pH decreases, pOH increases.

Considering the question given above, the solution (HCl) is acidic.

Therefore, the solution will have a low pH and a high pOH

Calculate how many grams of sodium hypochlorite can be theoretically formed when 1.23 mol of sodium hydroxide is combined with 1.36 mol of chlorine.

Answers

Answer:

45.78 g NaClO

Explanation:

The reaction that takes place is:

2NaOH + Cl₂ → NaCl + NaClO + H₂O

In order to react completely, 1.36 moles of chlorine would require (2*1.36) 2.72 moles of NaOH. There are more moles than that, so NaOH is the limiting reactant.

We calculate the moles of NaClO formed, from the limiting reactant:

1.23 mol NaOH * [tex]\frac{1molNaClO}{2molNaOH}[/tex] = 0.615 mol NaClO

Finally we convert NaClO moles to grams, using its molecular weight:

0.615 mol NaClO * 74.44 g/mol = 45.78 g NaClO

c) From the ice to the person, only
d) From the ice to the person and air, and from the air to the person

Answers

Answer:

b) From the person to the ice, and from the air to the ice

Explanation:

The direction of heat flow in the room is from the person to the ice and from the air to the ice.

The ice is at the lowest temperature.

Heat flows from a place with a higher measure of heat to a place with a lower amount of heat. Since the ice has the lowest heat, there is a thermal gradient set up. Heat will flow from the body and air towards to the ice.

A student has a balloon with a volume of 2.5 liters that contains 4.0 moles of air. The ballon has a small leak, allowing one mole to escape, leaving just 3.0 moles of air inside the balloon. What is the balloon's new volume after the air has escaped?

Answers

Answer:

1.9 L

Explanation:

Step 1: Given data

Initial number of moles of air (n₁): 4.0 molInitial volume of the balloon (V₁): 2.5 LFinal number of moles of air (n₂): 3.0 molFinal volume of the balloon (V₂): ?

Step 2: Calculate the final volume of the balloon

According to Avogadro's law, the volume of an ideal gas is directly proportional to the number of moles. We can calculate the final volume of the balloon using the following expression.

V₁ / n₁ = V₂ / n₂

V₂ = V₁ × n₂ / n₁

V₂ = 2.5 L × 3.0 mol / 4.0 mol

V₂ = 1.9 L

10. For each of the following pairs of ionic compounds, state which would be expected to have the higher (more negative) lattice energy.

a. LiF or KBr

b. NaCl or MgS

c. MgO or RbI

Answers

Answer:

C I belive

Explanation:

The higher lattice energy in option a is for LiF. Similarly, MgS have higher lattice energy that NaCl and  MgO have higher lattice energy than RbI.

What is lattice energy?

Lattice energy of a compound is the energy required to convert one mole of that compound into its constituent gaseous ions. Lattice energy increases as the size of the ion decreases. As well as, higher the charge of the ions higher will be the lattice energy.

In LiF and KBr, Li and F are the smaller ions and is having higher lattice energy. In the case of NaCl and MgS, Mg and S are having +2 charge and are smaller causes MgO higher in lattice energy.

Similarly in the case of MgO and RbI the same concept can be applied. Rb⁺ and I⁻ are bigger ions where as Mg²⁺ and O²⁻ are comparatively smaller and have higher charge result in higher lattice energy.

Thus compound which have higher lattice energy in option a is LiF, in option b is MgS and in option C is MgO.

A compound of copper and sulfur contains 76.84 g of metal and 38.53 g of nonmetal. How many grams of copper are in 3801 kg of the compound? How many grams of sulfur?

Answers

Answer:

There are:

2'531,500 g Cu1'269,500 g S

Explanation:

First calculate the percentage of Cu and S in the compound:

Total mass = 76.84 g + 38.53 g = 115.37 g% metal (Cu) = 76.84/115.37 * 100% = 66.6%% metal (S) = 38.53/115.37 * 100% = 33.4%

These percentages will remain the same no matter how much of the compound we analyze.

Now we calculate the grams of Cu and S in 3801 kg of the compound:

kg Cu = 3801 kg * 66.6/100 = 2531.5 kg Cug Cu = 2531.5 kg * 1000 = 2531500 g Cukg S = 3801 kg * 33.4/100 = 1269.5 kg Sg S = 1269.5 kg * 1000 = 1269500 g S

2.If a liquid has a volume of 5800 mL and you need the volume in Liters, will the number appear to

become smaller or larger?

Answers

Answer:

The number becomes smaller

Explanation:

Volume = 5800mL

To be converted to L

The relationship between mL and Liters is given as;

1 L = 1000 mL

This means that;

1 L = 1000 mL

x L = 5800 mL

x = 5800 / 1000 = 5.8 L

Comparing 5.8 with 5800, the number becomes smaller.

Answers

Answer:

4

Explanation:

The Balmer series refers to a series of spectral emission lines of the hydrogen atom arising from electronic transitions from any higher level and terminating at the the energy level n= 2.

Using the relation;

1/λ = 1.09737*10^7 (1/2^2 -1/n^2initial)

We now have;

1/486 *10^-9 = 1.09737*10^7 (1/2^2 -1/n^2initial)

0.1875 = 1/2^2 -1/n^2initial

1/n^2initial = 1/2^2 - 0.1875

1/n^2initial = 0.0625

n^2initial = 16

ninitial = 4
