It would be a catabolic reaction or decomposition reaction.
No, the reaction 2K + Br2 is not balanced. To balance it, you would need to change the coefficients of the reactants and products so that the same number of each type of atom is present on both sides of the reaction arrow.
To determine the coefficient of Al in a balanced chemical equation, you would need to provide the specific equation you are referring to. Once you provide the equation, we can help you identify the coefficient of Al in that particular chemical reaction.
Phosphine is not very soluble in water compared to nonpolar substances. If you were to write a balanced equation for the reaction of PH3 with water, it would be an equilibrium reaction.
Since the ratio of potassium to oxygen is 2:1 in the compound, the coefficient of oxygen in the balanced equation would be 1. The balanced equation for the reaction of potassium with oxygen to form this oxide would be 4K + O2 -> 2K2O.
The coefficient of Al in a balanced chemical equation would depend on the specific reaction being considered. It is determined by ensuring that the number of atoms of each element is the same on both sides of the equation.
The balanced equation for AI(NO3)3 is not provided, but in a typical chemical equation, the coefficient for AI(NO3)3 would be 1.
C3H8 + 5O2 = 3CO2 + 4H2O, so the coefficient for O2 is 5
the answers is 6 _apex
The balanced chemical equation would be: NF3 + F2 -> N + 3F2 The coefficient for fluorine would be 2 and the symbol is F2.
To provide the balanced chemical equation, I would need to know the specific reaction you are referring to. Can you please provide the reactants and products involved in the reaction?
That would depend on the coefficient in question. ------------------------------------------------------------------------------A coefficient indicates how many molecules or atoms of each reactant & product are involved in a reaction. -<3
The combustion reaction of octane is:2 C8H18 + 25 O2 = 16 CO2 + 18 H2OSo, the number of oxygen molecules is 25.The isomer trimethylpentane is used as standard in octane rating: the end of the scale at 100.
This reaction is not balanced because the number of sulphur atoms is not the same on each side of the equation. There is one sulfur atom on the left (SO2) but two sulfur atoms on the right (H2SO3). Balancing the equation would involve changing the coefficient in front of one or more of the compounds.
