H2Mg the 2 is a subscript though.
Does 2HCI plus Mg equal 2Mg atoms
The answer is 0
2g + 5h
To determine the moles of H₂ produced from the reaction between magnesium (Mg) and sulfuric acid (H₂SO₄), we start with the balanced chemical equation: [ \text{Mg} + \text{H}_2\text{SO}_4 \rightarrow \text{MgSO}_4 + \text{H}_2 ] From the equation, 1 mole of Mg produces 1 mole of H₂. The molar mass of Mg is approximately 24.31 g/mol. Given 230 mg of Mg (or 0.230 g), the moles of Mg are calculated as follows: [ \text{Moles of Mg} = \frac{0.230 , \text{g}}{24.31 , \text{g/mol}} \approx 0.00946 , \text{moles} ] Thus, 0.00946 moles of Mg will produce approximately 0.00946 moles of H₂.
In pure water, they are equal.

1000mg = 1gr .So that means it's 2gr .
There are 2.75 equivalents of Mg^2+ present in a solution that contains 2.75 mol of Mg^2+. This is because the number of equivalents is equal to the number of moles for ions with a +2 charge.
2 becasuse 500 mg plus 500mg = 1000mg 1000mg= 1 gram
In the equation "you = mgh", divide both sides of the equation by mg, or you/mg = mgh/mg. The answer then is h = you/mg.
H, Mg, Zn, Cu
minus 15.
