In the reaction C3Hg + 502 — 3CO2 + 4H20, what is the ratio of moles of oxygen used to moles of H2O
produced?
O 5:3
04:5
0 3:5
O 5:4

5:4

Explanation:

The equation given is balanced. There are 5 O2's on the left (reactant side) and then 4 H2O's on the right (product side). Thus, it's a 5:4 ratio.

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
