Most of these stoichiometry problems are worked the same way.
Here is a step by step procedure.
7.) How many moles of fluorine are required to react with 12 g of sodium iodide?
I already balanced it but am confused to go from here
F2 + 2 NAi ---- 2 NaF + I2
12 g NaI + 2 mol NAI/149.89 gNAi * 1 mol NAF/1 mol NAi * 1 mol F2 / 2 mol NaF
1. Write and balanced the equation. Except for a couple of typos you've done that.
F2 + 2NaI ---- 2 NaF + I2
2. Convert what you have into mols. mols NaI = grams NaI/molar mass NaI= approx 0.08 but that's an estimate.
3. Now convert mols NaI to mols F2 using the coefficients in the balanced equation. That's
approx 0.08 x (1 mol F2/2 mols NaI) = approx 0.08 x 1/2 = ?
7.) How many moles of fluroine are required to react with 12 g of sodium iodide?
I already balanced it but am confused to go from here
F2 + 2 NAi ---- 2 NaF + I2
12 g NaI + 2 mol NAI/149.89 gNAi * 1 mol NAF/1 mol NAi * 1 mol F2 / 2 mol NaF
1.) how many grams of magnesium are needed to react with 1.25 mol of hydrochloric acid?
2.) Carbon and sulfur dioxide react to form carbon disulfide and carbon monoxide. How many moles of carbon disulfide would be expected if 7.09 g of carbon monoxide were produced
Here is what I did but idk if it is correct.
HELP?
7.09 g CO * 1mol CO/28.01 gCO * 1 molC/ 4 mol CO * 1 mol CS2/5 mol C=
3.) Calculate the mass of sodium hydroxide required to completely neutralize 21.7 g of sulfuric acid
2 NaOH + H2SO4 ---- Na2SO4 + 2 H2O
...
21.7 g H2SO4 * 1mol H2SO4/98.079 g H2SO4 * 2 mol NaOH/1 mol H2SO4=

Thankyou thankyou so much. Making it harder than it should be.
