Identify the terms,like terms,coefficients and constants <br><br><br> 2+3a+9a
yawa3891 [41]
Like terms in algebra are terms that have the same variables and power. Constants contain only numbers, we call them constants because their values don't change. Coefficients are the numbers in front of the variable ex: 5y in that expression 5 is the coefficient. So in the expression 2+3a+9a there is one constant which is 2 the likes terms are 3a and 9a because they have the same variable. And the coefficients are 3 and 9 because they are in front of the variable.

Potassium dihydrogen phosphate KH2PO4 and sodium nitrate NaNO2 solutions are mixed together in a beaker. Determine the net ionic
Aleksandr-060686 [28]

Potassium dihydrogen phosphate (KH2PO4) and sodium nitrate (NaNO2)

Molecular equation:

KH₂PO₄ (aq) + 3NaNO₂(aq) → Na₃PO₄(s) + KNO₂(aq) + 2HNO₂ (aq)

The net ionic equation is:

3Na⁺(aq) + PO₄⁻(aq) → Na₃PO₄(s)

The rest of the ions are spectator ions and tend to cancel out on both sides of the reaction.
