single replacment reaction
When hydrochloric acid (HCl) is mixed with magnesium (Mg), a chemical reaction occurs where hydrogen gas (H2) is produced and magnesium chloride (MgCl2) is formed. This reaction is represented by the following equation: 2HCl + Mg → MgCl2 + H2.
Fe + 2HBr = H2 + FeBr2 Iron plus hydrobromic acid equals hydrogen gas plus iron (II) bromide
yes as zinc is oxidised and hydrogen is reduced
HBr + NaOH ------> NaBr + H2O This is an acid-base reaction. The compounds will disassociate into ions in solution. The hydrogen from the HBr will go to the OH- and form water. The NaBr is a salt.
The pH of water is 7, which is considered neutral. This is because the concentration of hydrogen ions equals the concentration of hydroxide ions in pure water, making it neither acidic nor basic.
A neutral solution of about 7 pH.
Calcium and water react to form calcium hydroxide and hydrogen. Ca + 2H2O --> Ca(OH)2 + H2
It equals into hydrogen gas (which is automatically ignited by the reaction's heat) and potassium hydroxide, which is instantly dissolved in the unreacted water. It doesn't equal the world's safest reaction, however. Wear safety goggles and the proper gear.

The pH of water is 7, which is considered neutral. This is because the concentration of hydrogen ions equals the concentration of hydroxide ions in pure water, making it neither acidic nor basic.
Hydrogen + Bromine ---> Hydgrone Bromide H + Br ---> HBr
In a solution with pH 7, the concentration of hydroxide ions (OH-) equals the concentration of hydrogen ions (H+), with each being 10^-7 moles per liter. This represents a neutral solution where the two ions balance each other out.
Magnesium reacts with oxygen to form magnesium oxide, and reacts with hydrogen to form magnesium hydride. There is no single chemical reaction that combines all three elements together to form a specific compound.
The word eq'n is:- Hydrochloric Acid + Aluminium hydroxide = Aluminium Chloride + Water. Here is the BALANCED reaction eq'n 3HCl(aq) + Al(OH)3(aq) = AlCl3(aq) + 3H2O(l)
