part 1 (0.5 point) potassium combined with bromine is... formula: name: part 2 (0.5 point) calcium combined with hydrogen is... formula:
Answer
Explanation:
Step1: Determine potassium and bromine ions
Potassium (K) forms a +1 ion ($K^+$) and bromine (Br) forms a - 1 ion ($Br^-$).
Step2: Write the chemical formula
To balance the charges, the formula is $KBr$.
Step3: Name the compound
The name of the compound is potassium bromide.
Step4: Determine calcium and hydrogen ions
Calcium (Ca) forms a +2 ion ($Ca^{2 +}$) and hydrogen (H) forms a -1 ion ($H^-$) in this context.
Step5: Write the chemical formula
To balance the charges, the formula is $CaH_2$.
Step6: Name the compound
The name of the compound is calcium hydride.
Answer:
Part 1: formula: $KBr$ name: potassium bromide Part 2: formula: $CaH_2$ name: calcium hydride
