Label the chemical equation. 2 Mg(s) + O2(g) → 2 MgO(s)
Label the chemical equation.
2 Mg(s) + O2(g) → 2 MgO(s)

Kindly check Explanation

Explanation:

Given the chemical equation:

2 Mg(s) + O2(g) → 2 MgO(s)

2 molecules of Magnesium + Oxygen gas (Reactant)

→ ( yield)

2 molecules of magnesium oxide (product)

2 in Mg and MgO (coefficients)

2 in Oxygen gas (subscript)

Solid (s) - physical state of Reactant Mg

Gas (g) - physical state of Reactant O2

Solid (s) - physical state of product 2MgO

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.

i think it's c. i'm not sure but i think so.
