Answer:
F G there you go the guy on top is right
Explanation:
F G
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.
Element which possess different number of "Neutrons" in different situations could be an isotope of the atom
Ex. - 17 Cl 34, 17 Cl 35, 17 Cl 36
They all the isotopes.
Hope this helps!
There should be 22 figures .
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.
