The reaction is;
2Na + 2H2O → 2NaOH + H2
Answer:
4.4 × 10^(23) atoms
Explanation:
The reaction is;
2Na + 2H2O → 2NaOH + H2
2 moles of Na produces 1 mole of H2 from the equation reaction.
Thus, since 8.2 L of hydrogen gas at STP are produced. And we know that at STP, 1 mole of a gas will have a volume of 22.4 L, and also, We know according to avogadro's number that, 1 mol = 6.02 × 10^(23) atoms, Thus;
8.2 L of H2 × (1 mole of H2/22.4 L) × (2 mole of Na/1 mole of H2) × (6.02 × 10^(23) atoms/1 mole of Na) = 4.4 × 10^(23) atoms
Answer:
it all depend one the amount of moles on the gas line and you probe need to use the question before this one

<u>Answer:</u>
<em>Two atoms of the same element are most likely to form Molecule.</em>
<em></em>
<u>Explanation:</u>
are some examples
1 molecule of fluorine contains 2 atoms of Fluorine.
Similarly,
One molecule of chlorine (Cl),
One molecule of bromine (Br),
One molecule of iodine (I)
Each contains two atoms of the same element. We call these molecules as homodiatomic molecules.
There are 7 diatomic molecules which are as follows,
They are 
and 
It is an astronomer. the person who studies the universe and everything in it
Answer:
The 4th option!
Explanation:
If somebody gave you a ton of energy, what would you be doing? Moving around, jittering, fidgeting, feeling all jumpy, right? Well, that's what the molecules would be doing too xDD
