Answer:
1640 kJ are involved in the reaction
Explanation:
In the reaction:
B₂H₆(g) + 6Cl₂(g) → 2 BCl₃(g) + 6HCl(g)
<em>1 mol of B₂H₆(g) with 6 moles of Cl₂(g) produce 1396 kJ of energy.</em>
<em />
Now if 32.5g of B₂H₆(g) react with excess Cl₂(g), moles involved in reaction are:
If 1 mol produce 1396kJ of energy, 1.175 moles produce:
Thus, <em>1640 kJ are involved in the reaction</em>
Answer:
<h2>78.13 J</h2>
Explanation:
The kinetic energy of an object can be found by using the formula
m is the mass
v is the velocity
From the question we have
We have the final answer as
<h3>78.13 J</h3>
Hope this helps you
Answer:
Yes
Explanation:
It is balanced because On both sides there are 4 hydrogen atoms and 2 oxygen atoms, or in this case, 2 molecular hydrogens and 1 molecular oxygen, which made hydric acid, aka dihydrogen monoxide, or universally, as water.
Because it doesn't get direct sunlight so it gets cool
