Answer:
No, the puddle was formed because of the sun, because if there was snow and it rained then it would have turned slippery or icy
Answer is: 12 <span>moles of water will be produced.
</span>Balanced chemical reaction: N₂H₄ + O₂ → N₂ + 2H₂O.
n(N₂H₄) = 6 mol.
From balanced chemical reaction: n(N₂H₄) : n(H₂O) = 1 : 2.
n(H₂O) = 2 · n(N₂H₄).
n(H₂O) = 2 · 6 mol.
n(H₂O) = 12 mol.
n - amount of substance.
<u>Conversion Factors:</u>
1.61 km = 1 mile
60 sec = 1 min
60 min = 1 hour

Use dimensional analysis to solve.

× 
= 36 miles/hour
If done properly, you should be left with the units <em>miles/hour</em>

But what is the width of the molecule
Answer:
Hope this helps kinda got confused mid way
Explanation:
So the hydrogen sulphide is H2S for the molecular formula. Then the mass of hydrogen sulphide would be 1×2+32= 34g/mol At STP.
