This is the composition reaction using the gasses hydrogen and oxygen to make water.
Solve the following equation for A : 2A/3 = 8 + 4A
79
(5, -8)
The given equation is not that of a parabola.
The coefficients are the numbers written in front of the chemical formulas in a chemical equation, and tells how much of a certain substance is involved in the reaction. When there is no number, it is understood to be one. For example, the following equation, which represents the combustion of methane (CH4), could be read in a couple of different ways. CH4 + 2O2 --> CO2 + 2H2O One molecule of methane plus two molecules of oxygen produces one molecule of carbon dioxide plus two molecules of water. or One mole of methane plus two moles of oxygen produce one mole of methane plus two moles of water.
2K(s) + 2H2O(l) = 2KOH(aq) + H2(g) The eq'n is balanced. The coefficients ( molar ratios) in order of the reation eq'n are 2:2:::2:1
This simple equation is: 2H2 + O2 = 2H2O
The balanced equation is Ca(OH)2 + H2SO4 → CaSO4 + 2H2O.
HCl + NaOH = H2O + NaCl is already balanced.
2Na + 2H2O -> H2 + 2NaOH
The balanced equation for the reaction is: CH4 + 2O2 → CO2 + 2H2O. This balance was achieved by making sure the number of atoms of each element is the same on both sides of the equation.
2Na + 2H2O -------> 2NaOH + H2
4hf+2co2 --> 2h2o+2cf2
2H2 + O2 --> 2H2O
The combustion of methane can be balanced in the following manner. One molecule of CH4 plus two molecules of O2 produces one molecule of CO2 plus one molecule of H2O.
NH4NO3 (aq) N2O (g) + 2H2O (l)
The balanced equation is: 4H₂ + 4NO → 4H₂O + 2N₂.
