swers
name the following acids given the formula or w classical system. t/i - 4
a) h₂te
b) h₃po₄
c) nitric acid
d) hydrophosphoric acid

Explanation:

Step1: Identify naming rules for binary acids

Binary acids (compounds with hydrogen and one other non - metal) are named as "hydro - <non - metal root> - ic acid". For $H_2Te$, the non - metal is tellurium. Its root is "tellur", so the name is hydrotelluric acid.

Step2: Identify naming rules for oxyacids

Oxyacids are named based on the polyatomic anion. For $H_3PO_4$, the polyatomic anion is phosphate ($PO_4^{3 - }$). The name of the acid is phosphoric acid.

Step3: Write the formula for nitric acid

Nitric acid has the formula $HNO_3$.

Step4: Write the formula for hydrophosphoric acid

Hydrophosphoric acid is a binary acid with hydrogen and phosphorus. Its formula is $H_3P$.

Answer:

a) Hydrotelluric acid
b) Phosphoric acid
c) $HNO_3$
d) $H_3P$
