B. I am studying this right now and I know this for a fact because C, D, and A are true and protons are located inside the nucleus and electrons are located outside the nucleus which means B is your answer.

ZnS (s) + AIP(s) → AI₂S₂(s) + Zn P₂(s)
Allisa [31]

Answer:

3 ZnS (s) + 2 AIP(s) ---> AI₂S₃(s) +  Zn₃P₂(s)

Explanation:

I believe you are asking for this reaction to be balanced. However, after looking more closely, those are not the products that would be created from the reactants. Assuming this is a double-displacement reaction, and taking the most common charges of the ions into consideration, the actual products would be AI₂S₃(s) + Zn₃P₂(s). I apologize if I assumed incorrectly.

For an equation to be balanced, there needs to be the same amount of each element on both sides of the equation.

The unbalanced equation:

ZnS (s) + AIP(s) ---> AI₂S₃(s) + Zn₃P₂(s)

<u>Reactants</u>: 1 zinc, 1 sulfur, 1 aluminum, 1 phosphorus

<u>Products</u>: 3 zinc, 3 sulfur, 2 aluminum, 2 phosphorus

As you can see, there is an unequal amount of each element on the reactants and products side. To balance the equation, coefficients in front of the compound(s) will be necessary.

The balanced equation:

3 ZnS (s) + 2 AIP(s) ---> AI₂S₃(s) +  Zn₃P₂(s)

<u>Reactants</u>: 3 zinc, 3 sulfur, 2 aluminum, 2 phosphorus

<u>Products</u>: 3 zinc, 3 sulfur, 2 aluminum, 2 phosphorus

You are trying to determine the volume of the balloon needed to match the density of the air in the lab. You know that if you ca
9966 [12]

To solve this problem, we must be given first the density of air at 20 degrees Celsius. Looking up online, this is equal to:

density air (20C) = 0.0012041 g/mL

so that the volume is:

volume balloon = 0.57 g / (0.0012041 g/mL)

<span>volume balloon = 473.38 mL</span>
