Mass increases as atoms are rearranged during a chemical reaction. In a chemical reaction, mass is neither created nor destroyed. In a chemical reaction, mass is neither created nor destroyed. To balance a chemical equation, additional mass may be created. To balance a chemical equation, additional mass may be created. Mass is not measurable in a chemical reaction. Mass is not measurable in a chemical reaction.

Question

GPT-4o mini · Answer

Here are the answers to your questions:

Question 1:
A) What are the reactants in a chemical formula?
Response: the atoms prior to the chemical reaction, found on the left side of the equation

Question 2:
A) What does the Law of Conservation of Mass say about a chemical reaction?
Response: In a chemical reaction, mass is neither created nor destroyed.

Question 3:
A) Which of the following molecules shows two atoms of hydrogen (H)?
Response: \( \text{H}_2\text{O} \) (2H2O means two water molecules, each containing two hydrogen atoms, which totals four hydrogen atoms)

Question 4:
A) From the Periodic table, it can be determined that iron (Fe) has an atomic mass of 56 amu, oxygen (O) has an atomic mass of 16 amu, and hydrogen (H) has a mass of 1 amu. What would the atomic mass of Fe(OH)3 be?
To calculate the mass of Fe(OH)3:

1 Fe = 56 amu
3 O = 3 × 16 amu = 48 amu
3 H = 3 × 1 amu = 3 amu
Total = 56 + 48 + 3 = 107 amu
Response: 107 amu
