The process that changes one set of chemicals into another set of chemicals is called a chemical reaction. The correct answer is option c.
A chemical reaction is a process in which chemical bonds between atoms and molecules are broken and formed, resulting in the creation of new substances with distinct chemical properties.
In a chemical reaction, the reactants are the starting substances that react with each other, while the products are the new substances that are formed.
For example: When hydrogen gas reacts with oxygen gas in the presence of a spark or flame, a chemical reaction occurs that produces water as a product:
Therefore, a chemical reaction is the process of transforming one set of chemicals into another set of chemicals. Option c is the correct answer.

(2) The mass of an electron is greater than the mass of a neutron.
(3) The mass of a proton is greater than the mass of an electron.
(4) The mass of a proton is greater than the mass of a neutron.
Answers
atoms are made of 3 types of subatomic particles - electrons, protons and neutrons
mass of proton is 1 atomic mass unit and proton is also 1 atomic mass unit
masses of protons and neutrons are very similar
mass of an electron is 1/1840th of 1 atomic mass unit
mass of electron is insignificant when compared to masses of neutrons and protons
protons and neutrons have a larger mass than electrons
from the given options correct answer is
(3) The mass of a proton is greater than the mass of an electron
Protons have mass 1
Neutrons have mass 1
(1) 0 is not greater than 1
(2) 0 is not greater than 1
(3) 1 is greater than 0
(4) 1 is not greater than 1
So the answer is (3) The mass of a proton is greater than the mass of an electron

They observed the sample and made the observations below. • There are various components in the sample. • Different regions of the sample have different properties. Based on these observations, how will the students classify the matter?
a. heterogeneous mixture
b. homogeneous mixture
c. chemical ...
Answers
A homogeneous mixture is a combination of 2 or more substances wherein its concentration is evenly distributed throughout the mixture. This means that you cannot identify the different components or properties of the mixture. A heterogeneous mixture, on the other hand, is a combination of 2 or more substances wherein its components are unevenly distributed. This means that its components can visibly be identified from each other.

Final answer:
The volume of the gas sample would be 477.78 mL.
Explanation:
The student is asking about the change in volume of a gas sample when the pressure is increased. This can be solved using Boyle's law, which states that the pressure and volume of a gas are inversely proportional at constant temperature. The equation for Boyle's law is: P1 * V1 = P2 * V2
We are given the initial conditions: T1 = 25.2°C, V1 = 536 mL, and P1 = 0.838 atm. We need to find V2 when P2 = 0.937 atm. Using the Boyle's law equation, the volume can be calculated as: V2 = (P1 * V1) / P2
Plugging in the values, we get: V2 = (0.838 atm * 536 mL) / 0.937 atm = 477.78 mL
Therefore, the volume of the gas sample would be 477.78 mL (Option A) when the pressure is increased to 0.937 atm.
