Question

In a chemical reaction two molecules with a total mass of 76 amu react to form a single molecule. What is the mass of the molecule that is formed?

A. 228
B. 38
C. 76 ***
D. 152

Answer 1

Yes, absent any relativistic effects :)

Answer 2

Science 8 A Conversation in Chemical Reactions

1. Zn+2HCl = H2+ZnCl2
2. The total number of atoms does not change, so mass is conserved in the reaction.
3. 215 amu
4. 76 (question above)

[AI-generated answer — Explain Bot]

To determine the mass of the molecule that is formed in this chemical reaction, we first need to understand the concept of atomic mass units (amu). Atomic mass unit is a unit used to measure the mass of atoms and molecules.

In this case, we have two molecules with a total mass of 76 amu reacting to form a single molecule.

To find the mass of the molecule that is formed, we need to know the individual masses of the two reacting molecules. Unfortunately, the question does not provide that information.

However, based on the answer choices, we can assume that the mass of each reacting molecule is 38 amu. Therefore, when they react to form a single molecule, the total mass remains the same, which is 76 amu.

So, the correct answer is C. 76.
