Question

In the balanced reaction: 3Cl2(g) + 6NaOH(aq) -> 5NaCl(aq) + NaClO3(aq) +3H2O(l). how many grams of water can be produced from 26 kilograms of sodium hydroxide?

What is the molar mass of nitroglycerin, C3H5(NO3)3?

The thermite reaction is given by: Fe2O3(s) + Al(s) -> Fe(l) + Al2O3 (s). How many grams of molten iron will be produced if 2.92 moles of iron (III) oxide is consumed?

Ns(g) +3H2(g) ->2NH3(g). How many grams of each reactant would be required to produce 2020 grams of product?

Answer 1

3Cl2(g) + 6NaOH(aq) -> 5NaCl(aq) + NaClO3(aq) +3H2O(l)

6 moles of NaOH react with Cl2 to gives 3 moles of H2O

6*40g of NaOH react with Cl2 to gives 3*18g of H2O

26000g of NaOH react with Cl2 to gives = 3*18*26000/6*40    = 5850g of H2O >>>>answer

2.

The molar mass of nitroglycerin, C3H5(NO3)3    = 12*3 + 1*5 + 14*3 + 16*9   = 227g/mole >>>>answer

3.

     Fe2O3(s) + 2Al(s) -> 2Fe(l) + Al2O3 (s).

1 moles of Fe2O3 to gives 2 moles of Fe

1 moles of Fe2O3 to gives 2*56g of Fe

2.92moles of Fe2O3 to gives = 2*56*2.92/1   = 327.04g of Fe

3.

      N2(g) +3H2(g) ->2NH3(g)

2 moles of NH3 produced from 1 mole of N2

2*17g of NH3 produced from 28g of N2

2020g of NH3 produced from = 28*2020/2*17   = 1663.53g of N2

2 moles of NH3 produced from 3 mole of H2

2*17g of NH3 produced from 3*2g of H2

2020g of NH3 produced from = 3*2*2020/2*17   = 356.47g of H2 >>>>answer
