Answer:
The answer to your question is b. CaCrO₄
Explanation:
Data
H₂CrO₄ reacts with Ca(OH)₂
Process
H₂CrO₄ is an acid and Ca(OH)₂ is a base then this is a neutralization reaction.
H₂CrO₄ is an acid and Ca(OH)₂ is a base.
In a neutralization reaction, the products will always be water and a binary or ternary salt.
In the reaction, the salt will be Calcium chromate
Balanced chemical reaction
H₂CrO₄ + Ca(OH)₂ ⇒ CaCrO₄ + 2H₂O
Once a metal is above another in series it is more reactive than it and will be able to displace it from its compound. Ex: Iron will displace lead from its compound but Iron cannot displace zinc from its compound.
Hope this helps!

Answer:
The molarity of this KOH solutions 3.21 mol / L (option C is correct)
Explanation:
Step 1: Data given
Mass of KOH = 45.0 grams
Molar mass of KOH = 56.1 g/mol
Volume = 250.0 mL = 0.250 L
Step 2: Calculate moles KOH
Moles KOH = mass KOH / molar mass KOH
Moles KOH = 45.0 grams / 56.1 g/mol
Moles KOH = 0.802 moles
Step 3: Calculate molarity
Molarity KOH solution = moles KOH / volume water
Molarity KOH solution = 0.802 moles / 0.250 L
Molarity KOH solution = 3.21 mol / L
The molarity of this KOH solutions 3.21 mol / L (option C is correct)
