The answer for four is frequency.
The balanced chemical reaction is:
<span>2H2+O2-->2H2O
</span>
To determine the mass of hydrogen that is needed, we need use the initial amount of oxygen and relate it to hydrogen from the reaction given. We do as follows:
192 g O2 ( 1 mol O2 / 32 g O2) ( 2 mol H2 / 1 mol O2 ) ( 2.02 g H2 / 1 mol H2 ) = 24.24 g H2
It’s wave motion. Because when wave passes throug an object, some of the other material can go though on other object(s).
answer : Neutron, neutral subatomic particle that is a constituent of every atomic nucleus except ordinary hydrogen.
