Barium hydride reacts with water to produce barium hydroxide and hydrogen gas. BaH₂ (s) + 2 H₂O(l) → Ba(OH)2 (aq) + H₂ (9) If 7.474 g BaH2 is combined with 63.000 g H₂O, the reaction proceeds until all the BaH2 is consumed. The hydrogen gas escapes to the environment, and the final weight of the flask is 70.258 g. The remaining water is evaporated, leaving 9.190 g Ba(OH)2. What mass of water is consumed in the reaction? g H₂O

States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.

BaH₂ (s) + 2 H₂O(l) → Ba(OH)2 (aq) + H₂ (9)
If 7.474 g BaH2 is combined with 63.000 g H₂O, the reaction proceeds until
all the BaH2 is consumed. The hydrogen gas escapes to the environment, and
the final weight of the flask is 70.258 g. The remaining water is evaporated,
leaving 9.190 g Ba(OH)2. What mass of water is consumed in the reaction?
g H₂O
Transcribed Image Text:Ammonia gas can be prepared by the reaction of a metal oxide such as calcium
oxide with ammonium chloride.

If
267 g of
CaO and
435 g of
NH4Cl are mixed, what is the limiting reactant?
What mass of NH3 can be produced?
