Can anyone help me with a formula for solving this?

Determine the mass of sodium chlloride produced when 1.75moles of chlorine gas reacts with sodium?

Thanks.

I am trying to help my son with a bunch of questions on chemistry. He has to answer them in this format. I am stumped. I have read over the information, but it is confusing to me. Can you assist us by explaining the first one to me so I can explain to him? I would greatly appreciate it.

For the equation Ag + NO3 -  Ag + + NO

(Note: This reaction takes place in an acidic solution.)

Step 1: What substance is reduced?

Step 2: What substance is oxidized?

Step 3: What is the half reaction for oxidation?

Step 4: What is the half reaction for reduction?

Step 5: What is the net balanced equation?

Step 6: What is the reduced equation?

I am trying to help my son with this Chemistry problem, but we are lost...If there are 6.25 L of Hydrogen gas at a pressure of 1.95 ATM and a temperature of 243 K, how many grams of hydrogen are there?

Please help, and we would appreciate telling us how this works with the Pv=nRT. Thanks.

I am trying to help my son with this mole question. Can you explain it tome>?

The mole ratio of CO2 to C6H12O6 in the equation 6CO2 + 6H2O ---> C6H12O6 + 6O2 is what?

6:6

1:1

6:1

1:6

We are trying to figure out how they come up with the ratios, though, we don't just want the answer. Any help would be welcome.

I am trying to help my child with this question and I don't understand how the text is explaining it. Can anyone assist?
