Question

HNO3+AgCO3= Ba(NO3)2+AgSO4= AgNO3+Au= AgNO3+NaPO4=

Answer 1

Ba(NO3)2 + Ag2SO4 = BaSO4 + 2AgNO3

Ag2CO3 + 2HNO3 =2 AgNO3 + CO2 + H2O

AgNO3 + Au =  реакция не пойдет ( золото слабее серебра)

3AgNO3 + Na3PO4 = Ag3PO4 +3 NaNO3

Answer 2

The given chemical equations are:

1. HNO3 + AgCO3 = Ba(NO3)2 + AgSO4 2. AgNO3 + Au = AgNO3 + NaPO4

Let's break down each equation and explain what happens in each reaction.

Equation 1: HNO3 + AgCO3 = Ba(NO3)2 + AgSO4

In this equation, nitric acid (HNO3) reacts with silver carbonate (AgCO3) to form barium nitrate (Ba(NO3)2) and silver sulfate (AgSO4).

The balanced chemical equation for this reaction is:

2 HNO3 + AgCO3 = Ba(NO3)2 + AgSO4 + H2O + CO2

This equation shows that two molecules of nitric acid react with one molecule of silver carbonate to produce one molecule of barium nitrate, one molecule of silver sulfate, water, and carbon dioxide.

Equation 2: AgNO3 + Au = AgNO3 + NaPO4

In this equation, silver nitrate (AgNO3) reacts with gold (Au) to form silver nitrate and sodium phosphate (NaPO4).

However, it is important to note that this equation is not balanced. The balanced equation should be:

3 AgNO3 + Au = 3 Ag + Au(NO3)3

This equation shows that three molecules of silver nitrate react with one molecule of gold to produce three molecules of silver and one molecule of gold(III) nitrate.
