iron sulphide is formed
magnesium sulphide
Balanced equation first. 2Na + 2HCl >> 2NaCl + H2 25 grams Na (1mol Na/22.99g )(1mol H2/2mol Na ) = 0.54 moles of H2 produced.
CaS + 2HCl --> H2S + CaCl2
The equation is 2C4H10 + 13O2 --> 8CO2 + 10H2O This means that for each mole of butane there are 5 moles of water produced. We have 7.01 g of butane = 7.01/58 moles of butane = 0.12 moles. Thus we will get 5 x 0.12 moles of water, = 5 x 0.12 x 18 g of water = 10.88 g.
The mass of heavy water produced when 7,00grams of oxygen reacts with excess D2 is 7,875 g.

Approximately 240g of hydrogen gas are produced when 120.0g of zinc metal completely reacts with hydrochloric acid.
0.4 moles MgO

it is magnesium sulphate that should answer your question.
When limestone reacts with acid, Carbon Dioxide is produced.
