Question

what is the formula for sodium hydrogen sulfate? what is the formula for calcium hydroxide? what is the formula for potassium hydrogen carbonate?

Explanation:

Step1: Determine sodium hydrogen sulfate formula

Sodium has a +1 charge ($Na^+$), hydrogen sulfate has a - 1 charge ($HSO_4^-$). So the formula is $NaHSO_4$.

Step2: Determine calcium hydroxide formula

Calcium has a +2 charge ($Ca^{2 +}$), hydroxide has a -1 charge ($OH^-$). To balance the charges, we need 2 hydroxide ions. So the formula is $Ca(OH)_2$.

Step3: Determine potassium hydrogen carbonate formula

Potassium has a +1 charge ($K^+$), hydrogen carbonate has a -1 charge ($HCO_3^-$). So the formula is $KHCO_3$.

Answer:

Sodium hydrogen sulfate: $NaHSO_4$
Calcium hydroxide: $Ca(OH)_2$
Potassium hydrogen carbonate: $KHCO_3$
