In the following equation, how many volumes of hydrogen and oxygen combine to give how many volumes of water?

2H2(g) + O2(g) → 2H2O(g)

2. Consider the following equation, how many volumes of chlorine react with hydrogen and how many volumes of hydrogen chloride is formed?
Cl2(g) + H2(g) → 2HCl(g)

What type of matter is made of only one kind of atom

Answer explain why it is not possible to deduce a complete order of reactivity.

Count the number of each type of atom in the equation below, and then balance the equation. write in the numbers of atoms and coefficients. add a 1 if there should be no coefficient. cs2(l) + o2(g) → co2(g) + so2(g) c [ ] s [ ] o > c [ ] s [ ] o [ ] cs2(l) + [ ] o2(g) > [ ] co2(g) + [ ] so2(g)
