4Al(s) +302(g) ----> 2Al2O3(s)
3Ca + N2 = Ca3N2
2Na + FeO ---> Na2O + Fe
2Mg(s) + O2(g) -> MgO(s)
Fe + S2 ---> FeS2
If there is an excess of air, the reaction should produce diphosphorus pentoxide as its only product. If additionally the phosphorus molecule is simply a phosphorus atom, the balanced equation is: 4 P + 5 O2 -> 2P2O5. If phosphorus is considered to form a tetraatomic molecule, the equation would be: P4 + 5 O2 -> 2 P2O5
When aluminum carbide reacts with water, the products of the reaction are aluminum hydroxide and methane gas. The balanced equation for this reaction is Al4C3 + 12H2O -->4Al(OH)3 + 3CH4(g)
The balanced chemical equation for the reaction between aluminum (Al) and oxygen (Oβ) to form aluminum oxide (AlβOβ) is: [ 4 \text{ Al} + 3 \text{ O}_2 \rightarrow 2 \text{ Al}_2\text{O}_3 ] According to the balanced equation, 4 moles of aluminum (Al) produce 2 moles of aluminum oxide (AlβOβ). Therefore, if 4.0 moles of aluminum completely react, it will produce ( \frac{2}{4} \times 4.0 ) moles of aluminum oxide. Calculate that to find the answer.
3Ni(NO2)2 (aq) + 2Na3PO4 (aq) = Ni3(PO4)2 (s) + 6NaNO3 (aq)
This is not a correct question.
2Na + Cl2 -> 2NaCl
When balancing a chemical equation the reactants need to be balanced with the non-reactants. If you don't the formula will be produce negative results and you'll get the wrong answer.
The chemical equation is:2 AlBr3 + 3 Cl2 = 2 AlCl3 + 3 Br2
AlCl3 + 3H2O ---> Al(OH)3 + 3HCl.
This equation is P4O10 + 6 H2O -> 4 H3PO4.
The balanced equation is 2 KI + Pb(NO3)2 -> 2 KNO3 + PbI2.
The chemical equation is:C12H22O11 + 12 O2 = 12 CO2 + 11 H2O
The equation as given can not be balanced, because it is incomplete: When hydrogen peroxide decomposes to produce water, it also produces oxygen. A proper, balanced equation for the reaction is 2 H2O2 -> 2 H2O + O2.
