Which of the following could be the hypothesis supported by an investigation that demonstrates the law of conservation of mass in relation to chemical reactions?
A. If the reaction obeys the law of conservation of mass, then mass will be the same before and after the reaction.
B. If the reaction obeys the law of conservation of mass, then mass will increase after the reaction.
C. If the reaction obeys the law of conservation of mass, then mass will be different before and after the reaction.
D. If the reaction obeys the law of conservation of mass, then mass will decrease after the reaction.
According to the law of conservation of mass, mass is neither created nor destroyed in a chemical reaction. If the reaction obeys the law of conservation of mass, the mass before and after the reaction will be the same.
What does the law of conservation of mass?Any element's mass at the start of a reaction will equal its mass at the end of the reaction. Accounting for all reactants and products in a chemical reaction results in the same total mass at any point in time in any closed system.
When coal, for example, is burned, the carbon atom transforms into carbon dioxide. The carbon atom undergoes transformation from solid to gas, but its mass remains constant.
According to the law of conservation of mass, the amount of mass that enters a chemical reaction in the form of reactants must equal the amount of mass that exits the reaction process in the form of products. This is only possible in a closed system. For example, if 2g of reactant A reacts with 32g of reactant B, the mass of the product AB formed is 34g.

A 1.0 g sample of which substance contains the largest
number of molecules?
Answer:
Hydrogen (since this is all the info I'm working with)
Explanation:
Since we need to know how which substance has the most amount of molecules, we would need to look at the Atomic masses of these elements. Hydrogen has an atomic mass of 1.01g/mol whereas something like oxygen has an atomic mass of 16.00g/mol. Judging this, we can determine since a mole is made up of 6.02*10^23 molecules(Avogadro's number), and we have 1/1.01grams of hydrogen, we can deduce that Hydrogen would contain the largest amount of molecules

In describing weather completely, it is important to include, among other aspects, air pressure, precipitation, and humidity. Which of the following statements is false?
Wind is the movement of air that results from differences in air pressure.
Precipitation is a form of water that falls to Earth’s surface from the clouds.
Air typically moves from areas of lower pressure to areas of higher pressure.
When the temperature of the air cools to the dew point, the air is saturated, and water droplets will form.
Answer:
The false statement is - Air typically moves from areas of lower pressure to areas of higher pressure.
Explanation:
The wind is the air movement that takes place due to pressure differences or the temperature difference of air. Air moves from the higher pressure area to the lower pressure area. The more the difference will be the faster the air will move to a low-pressure area.
Precipitation is a form of water that falls from clouds to earth, it can be rainfall, snow and other forms. Dew is one of the forms that occur when the air cools down to the dew point and form droplets.
Answer:
Air typically moves from areas of lower pressure to areas of higher pressure.

There are approximately 1.204 x 10²⁴ oxygen atoms in 75 g of SO₃.
To calculate the number of oxygen atoms in 75 g of SO₃, we need to consider the molar mass of SO₃ and Avogadro's number.
The molar mass of SO₃ is calculated as follows:
Sulfur (S) = 32.07 g/mol
Oxygen (O) = 3 x 16.00 g/mol = 48.00 g/mol
Total molar mass of SO₍ = 32.07 g/mol + 48.00 g/mol = 80.07 g/mol
Next, we need to determine the number of moles of SO₃ in 75 g:
moles = mass / molar mass = 75 g / 80.07 g/mol ≈ 0.9369 mol
Since each molecule of SO₃ contains 3 oxygen atoms, we can calculate the number of oxygen atoms by multiplying the number of moles of SO₃ by Avogadro's number (6.022 x 10²³ atoms/mol) and then multiplying by 3:
Number of oxygen atoms = 0.9369 mol x 6.022 x 10²³ atoms/mol x 3 = 1.604 x 10²⁴ atoms
Therefore, there are approximately 1.204 x 10²⁴ oxygen atoms in 75 g of SO₃.

A farmer wants to build a pond for her cows. What step must she take in order to build the pond?
A. Dig into the zone of aeration.
B. Place a permeable material on the ground.
C. Keep the soil moist.
D. Place an impermeable material on the ground.
Answer:
Option A:
Dig into the zone of aeration
Explanation:
Within the lithosphere of the earth's surface, the zone of aeration is the zone directly above the water table, with a lot of pore spaces within the rocks. These pore spaces contain air and water, which can be used to water the cows.
Once the zone of aeration has been dug into, the farmer can tap into the underground reserve of water, which is stored within the pores of rocks. This water can now sip into the hole that was dug up by the farmer, forming a pond for the cows.
