The balanced chemical equation for the reaction is:
3CH₄ + 3 N₂Cl₄ → 3 CCl₄ + 3N₂ + 6H₂
<h3>What is a balanced chemical equation?</h3>A balanced chemical equation is a chemical reaction that has equal numbers of moles of chemical substances both in the reactant and the product side.
From the missing image that is attached below, we can see that the picture depicts that we have:
The reactant side:
- 3 molecules of CH₄ and 3 molecules of N₂Cl₄
The product side:
- 3 molecules of CCl₄, 3 molecules of N₂ and 6 molecules of H₂
Therefore, the balanced chemical equation for the reaction is:
3CH₄ + 3 N₂Cl₄ → 3 CCl₄ + 3N₂ + 6H₂

First, we need to find the probability, P, that the software is the standard version.
Out of 25,000 units, 5,000 were deluxe. That means the remaining 20,000 were standard. So, 20,000 out of 25,000, or
were standard. That means the probability of selecting a standard one at random is P = 0.8.
Next, we need to find the independent probability that any software box will contain the promotion. We know that 1 in 500 will, or
. That means P = 0.002.
To find the compound probability of these two events, we multiply the probabilities together to get
.
