Explanation: This is also the same as Mg + O₂ → MgO.
I believe that A is the answer. :)
A Hydrogen atom only
contains a single electron (1 e). Therefore for this atom, the quantum number
which determines the energy of an electron is best represented only by the
principal quantum number. The principal quantum number has a symbol of n.

The mass of 22.4 L of H2O at STP IS 18.0 grams
calculation
mass = moles x molar mas
Calculate the moles of water at STP
At STP 1 mole =22.4 L
what about 22.4 l of H2O
by cross multiplication
1mole x22.4 L/22.4 L = 1 mole
molar mass of water = (1 x2) + 16 =18 g/mol
moles is therefore = 8 g/mol x 1 mol = 18 grams
Answer: the answer is 2g because you subtract 32-34 and get 2 and add the get so 2g
