Answer:
4 moles AgCl
2 moles Ni(NO3)2
Step-by-step explanation:
2 moles AgNO3 makes 2 moles AgCl so the ratio is 1:1
So, x number of moles of AgNO3 will give x moles AgCl. Not more, not less. Therefore 4 moles AgNO3 will give us 4 moles AgCl.
2 moles of AgNO3 makes 1 mole Ni(NO3)2 so the ratio is 2:1
So, x number of moles of AgNO3 will give x/2 moles of Ni(NO3)2. Not more, not less. Therefore 4 moles AgNO3 will give us 4/2 = 2 moles Ni(NO3)2
