N2 + 3H2 --> 2NH3 N2 + 3H2 --> 2NH3
2Na(s)+O2(g) ----> Na2O2(s)
This equation is 2 Ba + O2 = 2 BaO.
Chromium don't react with water.
The balanced chemical equation for the reaction between oxygen and hydrogen is2H2 + 02 -> 2H2OThus 2.2 moles of oxygen reacts with 4.4 moles of hydrogen to form 4.4 moles of steam (water in gaseous state).The mass of H2O obtained is thus 4.4 x 18.0 = 79.2g.
N2 + 3H2 --> 2NH3 N2 + 3H2 --> 2NH3
2h2 + 2o -------> 2h2o
The reaction between strontium and nitrogen gas (which has the formula N2) produces strontium nitride, which has the formula Sr3N2. The balanced equation is: 3Sr + N2 -> Sr3N2. If there is an excess of oxygen available, the balanced equation for reaction between indium and oxygen is: 4 In + 3 O2 -> 2 In2O3.
2Na(s)+O2(g) ----> Na2O2(s)
This equation is 2 Ba + O2 = 2 BaO.
nitrogen monoxide and Water The balanced equation is as follow: 4NH3 + 5O2-->4NO + 6H2O
4Al(s) +302(g) ----> 2Al2O3(s)
C2h6+7o=2co2+3h2o
Chromium don't react with water.
S + o2 ------> so2
The balanced chemical equation for the reaction between oxygen and hydrogen is2H2 + 02 -> 2H2OThus 2.2 moles of oxygen reacts with 4.4 moles of hydrogen to form 4.4 moles of steam (water in gaseous state).The mass of H2O obtained is thus 4.4 x 18.0 = 79.2g.
SiO2 + 2Ca --> 2CaO + Si
