See explanation, some might be graded as wrong if it's an automatic grading system but most

Explanation:

1. lose
2. valence
3. noble (Atoms don't actually always do this, but since the word gas is after the blank, it is the only option)

4. 4

2. Which of the following is true about the total number of reactants and the total number of
Soloha48 [4]

9 moles of reactants chemically change into 11 moles of product.

Explanation:

In the reaction above, 9 moles of reactants chemically change into 11 mole of products. The coefficients in a reaction is the number of moles of the reacting atoms .

  • For example 8O₂ depicts 8 moles of two oxygen atoms.
  • The number of moles  is a unit for quantifying particles.
  • You can liken it to a dozen, gross or a score.
  • Since a mole of a substance contains avogadro number of particles. We can relate the number of moles to other parameters.

Answer both 8 and 9 will give u brain list with explanation as well so don’t just answer
goldfiish [28.3K]

Answer:

8. the answer is B.

9. the answer is A.

Explanation:

Hello!

8. In this case, by bearing to mind that the limiting reactant is always completely consumed and the excess one remain as a leftover at the end of the reaction, we can also infer that as all the limiting reactant is consumed, it must determine the maximum amount of product as the excess reactant will hypothetically produce a greater mass than expected; thus, the answer to this question is B.

9. In this case, since the mole ratio of oxygen to water is 1:2, the following proportional factor is used to calculate the produced mass of water:

3molO_2*\frac{2molH_2O}{1molO_2}=6molH_2O

Thus, the answer is this case is A.

Best regards!
