Question

31 if you have 100 particles of hydrogen and 100 particles of oxygen, how many units of water can you form? * (0.5 points)

Explanation:

Step1: Recall the chemical formula for water

The chemical formula for water is \( H_2O \), which means that to form one unit of water, we need 2 particles of hydrogen (\( H \)) and 1 particle of oxygen (\( O \)).

Step2: Determine the number of water units from hydrogen

We have 100 particles of hydrogen. Since each water unit requires 2 hydrogen particles, the number of water units we can form from hydrogen is \( \frac{100}{2} = 50 \).

Step3: Determine the number of water units from oxygen

We have 100 particles of oxygen. Since each water unit requires 1 oxygen particle, the number of water units we can form from oxygen is \( \frac{100}{1} = 100 \).

Step4: Identify the limiting reactant

The limiting reactant is the one that is completely consumed first and determines the amount of product formed. Here, hydrogen is the limiting reactant because it can only form 50 units of water, while oxygen can form 100 units. So, the number of water units formed is determined by the amount of hydrogen available.

Answer:

50
