Question

KCL+ AGNO3; Na2SO4 + Ba CL2; K2S +CuCl2;

Answer 1

Ответ:

KCl+AgNO3=KNO3+AgCl

Na2SO4+BaCl2=BaSO4+2NaCl

K2S+CuCl2=2KCl+CuS

Answer 2

It looks like you've provided three chemical equations, but they seem to be incomplete. Each chemical equation typically consists of reactants on the left-hand side and products on the right-hand side, along with the appropriate symbols and coefficients. Let me complete these equations for you:

1. KCl + AgNO3 → AgCl + KNO3 This is a double replacement reaction, where potassium chloride (KCl) reacts with silver nitrate (AgNO3) to form silver chloride (AgCl) and potassium nitrate (KNO3).

2. Na2SO4 + BaCl2 → BaSO4 + 2NaCl This is also a double replacement reaction, where sodium sulfate (Na2SO4) reacts with barium chloride (BaCl2) to form barium sulfate (BaSO4) and sodium chloride (NaCl).

3. K2S + CuCl2 → 2KCl + CuS This is a double replacement reaction, where potassium sulfide (K2S) reacts with copper(II) chloride (CuCl2) to form potassium chloride (KCl) and copper(II) sulfide (CuS).

Please note that chemical equations need to be balanced, which means the same number of atoms of each element must appear on both sides of the equation. If you need any further assistance or have more chemical equations to complete, feel free to ask!
