According to the reaction shown below, how many moles of H2 will form when 0.250 moles of Al react in excess H2S04? Round your final answer to three places after the decimal. Show your work. 2 Al (s) +3 H2SO4 (aq) --> Al2(SO4)3 (aq) + 3 H2 (g) Type your answer.

Enter the coefficients directly from the balanced chemical equation. Do not reduce to lowest terms. For example: If 3 moles H, react with 3 moles O, enter "3" for each, not "1". According to the following reaction: 2HC (aq) + Вa(ОН)2 (аq) ВаClz (aq) + 2н,0 (1) What would you multiply "moles of hydrochloric acid" by to convert to the units "moles of water" ? (number) (unit) moles HC1 moles H2O (number) (unit)

If 100.0 molecules of H2 and 38.0 molecules of O2 react, how many molecules of H2O can be produced in the reaction below? 2 H2(g) + O2(g) → 2 H2O(g) molecules 1 2 4 6. C 7 9. +/- х 100 +

2AI(OH)3 Consider the following balanced reaction: Al203+ 3H20 If 2.44 x 1020 Al203 formula units react, how many formula units of Al(OH)3 form? O 4.88 x 1020 formula unit O 0.500 formula unit O 2.00 formula unit O 2.44 x 1020 formula unit

Please answer the #7 to 12

For the reaction below, if 2.4 L of H2 gas are used, how many liters of NH3 (g) will be produced?  3H2 + N2 -> 2NH3

Hi I need help writing out a balanced chemical equation.

question is in the photo

For each of the following reaction, 16.0 g of each reactant is present initially: 3NO2(g)+H2O(l)→2HNO3(aq)+NO(g) 1.) Calculate the grams of HNO3 and H2O that would be produced.
