H2Mg the 2 is a subscript though.
Does 2HCI plus Mg equal 2Mg atoms
The answer is 0
2g + 5h
In pure water, they are equal.
73
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.
30 mg
