Potassium metal would be just K
Potassium would form a +1 ion (in first column/family)
Hydroxide is OH-1 So KOH is the formula for Potassium hydroxide to balance the charges
Hydrogen gas, as with most gases, is diatomic forming a covalent bond to share the two electrons
to help balance any equation with water, write it as H(OH)
K + H(OH) —> K(OH) + H2 is the unbalanced equation. Separating the water into its parts makes it easier to balance. To balance the H a coefficient 2 is placed in front of the H(OH) and a 2 in front of the K(OH) to balance the OH’s
K + 2H(OH) —> 2K(OH) + H2. A check shows that the K’s are not balanced so a 2 needs to be put in front of the K on the left.
2K + 2H(OH) —> 2K(OH) + H2. You can re-write H(OH) as H2O of you want.

NO + H2 —> N2 + H2O for formulas only. Don’t forget the symbols for gas (g) if required? Prefixes tell you the exact formula for covalent compounds. Gases are diatomic. Balance the Nitrogens first (2NO on reactant side) then the Oxygens, then Hydrogens...always balance the elements other than oxygen or nitrogen first. 2NO + 2H2 —> N2 + 2H2O04/04/21

Can u please answer these questions thank you How do metals high in the activity series react with water? How do metals in the middle of the activity series react with water? With hydrogen ions from an acid? How do metals low in the activity series react with water? With hydrogen ions from an acid?04/22/21
