Hydrogen & oxygen react chemically to form water.
How much water (H₂O) would form if
14.8g of hydrogen (H₂) reacted with 34.8g of oxygen (O₂)?
(H₂ + O₂ → H₂O)
When ammonium nitrate (NH₄NO₃) explodes, the products are nitrogen, oxygen, & water.
When 40g of ammonium nitrate explode, 14g of nitrogen and 8g of oxygen form. How many grams of water form?
(NH₄NO₃ → N₂ + O₂ + H₂O)
A solid mass of 25g is mixed with 60g of a solution. A chemical reaction takes place and a gas is produced. The final mass of the mixture is 75 g.
What is the mass of the gas released?
If 115g of a substance reacts with 84g of another substance.
What will be the mass of the products after the reaction?
