oxidation
It is called a numerator.
the index in a radical equation appears above and left of the root symbol and tells you what kind of root the radicand is.
6
In today's notation the above numerals represent: 1944
C represents 100, M represents 1,000 and X with a line over the top of it represents 10,000. The number would be MXC, there is a line above the X.
it means that manganese is a catalyst in the reaction
No equation above, but this is an example.2H+ + 2e- + 1/2O2 --> H2OThis is the equation, of the electron transport chain, that shows the final electron acceptor, oxygen, taking two protons and two electrons and forming water.This,2e-represents the two electrons and the negative charge they carry.
A catalyst is typically written above the arrow in a chemical equation, indicating its role in speeding up the reaction without being consumed itself. It is not listed as a reactant or product in the equation.
Manganese (Mn) above an arrow in a chemical equation typically means that the element is a catalyst for the reaction. This indicates that manganese is involved in the reaction mechanism, but is not consumed in the overall reaction and is regenerated at the end.
A catalyst is written above the arrow in a chemical equation to show that it is not consumed in the reaction and thus does not appear in the overall stoichiometry of the reaction. This means that it does not take part in the reaction as a reactant or a product, but it still helps in speeding up the reaction. Placing it above the arrow helps to distinguish it from other reactants or products.
It is called a numerator.
It means heat was supplied to make the reaction occur.
the chemical equation of muzzy zinc mixed with hydrochloric acid is given as follows .ZN + 2 HCl = ZNCl2 + H2.The above chemical reaction is balanced and is called double displacement reaction.
In this case, this is an acid-base reaction between nitric acid and ammonia. Nitric Acid is a strong acid, therefore, its hydrogen atom dissociates completely. The equation looks like this:HNO3(aq) + NH3(aq) => NH4NO3(aq)
There are 4 molecules of that particular reactant involved in the reaction.
The balanced equation for the reaction is: 3Ca + N2 -> Ca3N2 The reaction occurs at high temperatures, typically above 300°C.
The chemical equation for the reaction of iron with oxygen to form rust is 4Fe + 3O2 -> 2Fe2O3.
