3.) If you have 784 g of Sulfuric Acid (H2SO4), how many moles of Sulfuric
Acid is that? *

Answer: Soils are formed through the interaction of five major factors: time, climate, parent material, topography and relief, and organisms.

Soil structure affects plant growth in many, often surprising, ways. The most obvious effects are on root growth, which is strongly inhibited by hard soil, and which in turn influences the ability of the root system to extract adequate water and nutrients from the soil.

Answer:

R = 40 ohms

Explanation:

Given that,

The voltage of outlet, V = 120 V

Current flowing through the device, I = 3 A

We need to find the Resistance rating of  the power cord. Let the resistance is R. We know that,

Ohm's law, V = IR

Put all the values,

[tex]R=\dfrac{V}{I}\\\\R=\dfrac{120}{3}\\\\R=40\ \Omega[/tex]

So, the resistance rating of the power cord is equal to 40 ohms.

The respiratory system is the network of organs and tissues that help you breathe. basically your airways, lungs, and blood vessels so you quite literally need these to survive I mean your muscles need oxygen to function and your brain needs oxygen to function so without your respiratory system you wouldn't be able to move much and you would quickly pass out and die from the lack of oxygen to your brain there are other body processes that need oxygen as well but these are just two examples.

They are all correct because producers make their food(energy) through photosynthesis, they provide food to herbivores and therefore the rest of the food chain, and without them, the food chain would collapse and all the consumers would starve.

Answer:

(β-decay) is a type of radioactive decay in which a beta particle (fast energetic electron or positron) is emitted from an atomic nucleus, transforming the original nuclide to an isobar of that nuclide. For example, beta decay of a neutron transforms it into a proton by the emission of an electron accompanied by an antineutrino; or, conversely a proton is converted into a neutron by the emission of a positron with a neutrino in so-called positron emission.

Explanation:

Answer:

Beta decay occurs when, in a nucleus with too many protons or too many neutrons, one of the protons or neutrons is transformed into the other. ... In beta plus decay, a proton decays into a neutron, a positron, and a neutrino: p Æ n + e+ +n.

Answer: The molar mass of the gas is 9.878 g/mol.

Explanation:

According to Graham's law, the rate of diffusion is inversely proportional to square root of molar mass of gas.

[tex]Rate = \frac{1}{\sqrt{M}}[/tex]

where,

M = molar mass of gas

As given gas diffuses 1/7 times faster than hydrogen gas. So, its molar mass is calculated as follows.

[tex]\frac{R_{1}}{R_{2}} = \sqrt{\frac{M_{2}}{M_{1}}}\\[/tex]

where,

[tex]M_{1}[/tex] = molar mass of hydrogen gas

[tex]M_{2}[/tex] = molar mass of another given gas

[tex]R_{1}[/tex] = rate of diffusion of hydrogen

[tex]R_{2}[/tex] = rate of diffusion of another given gas = [tex]\frac{1}{7}R_{1}[/tex]

Substitute the values into above formula as follows.

[tex]\frac{R_{1}}{R_{2}} = \sqrt{\frac{M_{2}}{M_{1}}}\\\frac{R_{1}}{\frac{1}{7}R_{1}} = \sqrt{\frac{M_{2}}{2}}\\7 \times 1.414 = M_{2}\\M_{2} = 9.878 g/mol[/tex]

Thus, we can conclude that the molar mass of the gas is 9.878 g/mol.

Frost refers to solid ice that condenses and forms on surfaces like grass or windows.

Frost refers to a deposit of small white ice crystals formed on solid surfaces when the temperature falls below freezing temperature.

Frost forms when the temperature of the atmosphere is below freezing i.e. < 0°C.

Therefore, frost refers to solid ice that condenses and forms on surfaces like grass or windows.

Hello there!

In this case, according to the given information, we infer that we need the combined gas law in order to solve this problem:

[tex]\frac{P_2V_2}{T_2}} =\frac{P_1V_1}{T_1}}[/tex]

Thus, by suing the temperatures in Kelvins, we can solve for the final volume as shown below:

[tex]V_2 =\frac{P_1V_1T_2}{T_1P_2}}\\\\V_2 =\frac{(760mmHg)(22.4L)(232K)}{(273K)(805mmHg)} \\\\V_2=18.0L[/tex]

Answer:

D . It describes a compound being broken down into the elements from which it was formed.

Explanation:

A compound consists of two or more elements chemically combined together in a chemical reaction. The compound carbon monoxide is represented by the chemical symbol, CO. This means that it contains 1 atom of the carbon element and 1 atom of the Oxygen element.

This compound is formed when carbon is directly oxidized in a limited supply of oxygen. In the above reaction, this compound is disintegrated into its individual components, namely, carbon and oxygen.

Explanation: if I water this plant twice a day then it will grow 3 feet because the more water it gets the bigger it grows

Explanation:

amount of baking soda = 2.01 g

---> 2.01 g NaHCO3 × (1 mol NaHCO3/84.007 g NaHCO3)

= 0.024 mol NaHCO3

mass of the product = 1.28 g

Possible reactions:

NaHCO3(s) ---> NaOH(s) + CO2(g)

0.024 mol NaHCO3 × (1 mol NaOH/1 mol NaHCO3)

= 0.024 mol NaOH × (39.997 g NaOH/1.mol NaOH)

= 0.96 g NaOH

2NaHCO3(s) ---> Na2O(s) + 2CO2(g) + H2O(g)

0.024 mol NaHCO3 × (1 mol Na2O/2 mol NaHCO3)

= 0.012 mol Na2O × (61.9789 g Na2O)

= 0.73 g Na2O

2NaHCO3(s) ---> Na2CO3(s) + CO2(g) + H2O(g)

0.024 mol NaHCO3 × (1 mol Na2CO3/2 mol NaHCO3)

= 0.012 mol Na2CO3 × (105.9888 g Na2CO3/1 mol Na2CO3)

= 1.27 g Na2CO3

Conclusion:

Based on the mass of the product in the crucible and comparing it with the predicted product mass in different reactions, I conclude that Na2CO3 is the most likely product in the crucible.

Explanation:

Step 1: Calculate the amount of sodium hydroxide in moles

Volume of sodium hydroxide solution = 25.0 ÷ 1,000 = 0.0250 dm3

Rearrange:

Concentration in mol/dm3 =

Amount of solutein mol = concentration in mol/dm3 × volume in dm3

Amount of sodium hydroxide = 0.100 × 0.0250

= 0.00250 mol

Step 2: Find the amount of hydrochloric acid in moles

The balanced equation is: NaOH(aq) + HCl(aq) → NaCl(aq) + H2O(l)

So the mole ratio NaOH:HCl is 1:1

Therefore 0.00250 mol of NaOH reacts with 0.00250 mol of HCl

Step 3: Calculate the concentration of hydrochloric acid in mol/dm3

Volume of hydrochloric acid = 20.00 ÷ 1000 = 0.0200 dm3

Concentration in mol/dm3 =

Concentration in mol/dm3 =

= 0.125 mol/dm3

Step 4: Calculate the concentration of hydrochloric acid in g/dm3

Relative formula mass of HCl = 1 + 35.5 = 36.5

Mass = relative formula mass × amount

Mass of HCl = 36.5 × 0.125

= 4.56 g

So concentration = 4.56 g/dm3

The activity of four unknown metals based on their chemical changes is option B.

Chemical changes are defined as changes which occur when a substance combines with another substance to form a new substance.Alternatively, when a substance breaks down or decomposes to give new substances it is also considered to be a chemical change.

There are several characteristics of chemical changes like change in color, change in state , change in odor and change in composition . During chemical change there is also formation of precipitate an insoluble mass of substance or even evolution of gases.

There are three types of chemical changes:

1) inorganic changes

2)organic changes

3) biochemical changes

During chemical changes atoms are rearranged and changes are accompanied by an energy change as new substances are formed.
