The chemical formulas for their respective substances are the following:
Cadmium Sulfide: CdS
Sulfuric Acid: H₂SO₄
Hydrogen Sulfide: H₂S
This is a double replacement reaction where the substances of the reactants interchange to yield two products. The complete balance reaction would be:
<span>CdS (s) + H</span>₂<span>SO</span>₄<span> (aq) ----> CdSO</span>₄<span> (aq) + H</span>₂<span>S (g)
</span>
The other product is Cadmium Sulfate.
Answer:
2 atm
Explanation:
Chemical reactions are carried out at a certain rate. Sometimes that rate is quite slow, so we want to speed things up, which is usually used by increasing temperature, increasing pressure or adding a catalyst (a substance that increases the rate without changing itself).
If this is the case, then, when writing a chemical equation, we state these special conditions over a right arrow.
Now let's look at the answers:
- 25°C is a value and unit of temperature
- ∆ is a symbol that denotes change
- 2 atm is a value and unit of pressure (atmosphere is old unit for pressure)
- Pt is a chemical symbol for platinum, an element often used as a catalyst.
So, the correct answer is C) 2 atm
