Question

give the name or chemical formula, as appropriate, for each of the following acids. part a hbro3 spell out the full name of the compound. part b hbr spell out the full name of the compound. part c h3po4 spell out the full name of the compound.

Explanation:

Step1: Identify naming rules for oxy - acids

For an oxy - acid with the general formula $H_nXO_m$, if the central atom $X$ has an -ate ending in its oxo - anion, the acid name has an -ic ending. $HBrO_3$ has bromate ($BrO_3^-$) as its oxo - anion.

Step2: Name the acid

The name of $HBrO_3$ is bromic acid.

Step3: Identify naming rules for binary acids

For a binary acid $HX$ (where $X$ is a non - metal), the name starts with hydro - and ends with - ic acid. $HBr$ is a binary acid with bromine.

Step4: Name the binary acid

The name of $HBr$ is hydrobromic acid.

Step5: Identify naming rules for oxy - acids

$H_3PO_4$ has phosphate ($PO_4^{3 - }$) as its oxo - anion. Since the oxo - anion has an -ate ending, the acid name has an -ic ending.

Step6: Name the acid

The name of $H_3PO_4$ is phosphoric acid.

Answer:

Part A. bromic acid
Part B. hydrobromic acid
Part C. phosphoric acid
