when Ca gives out 2 electrons it is deducted from it's electronic configuration in it normal state
Answer:
V = 34.3 L
Explanation:
Given data:
Volume of hydrogen produced = ?
Mass of magnesium = 36.7 g
Temperature and pressure = standard
Solution:
Mg + 2HCl → MgCl₂ + H₂
Number of moles of magnesium:
Number of moles = mass/molar mass
Number of moles = 36.7 g/ 24 g/mol
Number of moles = 1.53 mol
Now we will compare the moles of magnesium with hydrogen.
Mg : H₂
1 : 1
1.53 : 1.53
Number of moles of hydrogen produced = 1.53 mol
Volume of hydrogen:
PV = nRT
V = nRT / P
V = 1.53 mol × 0.0821 atm.L/mol.K × 273 K/ 1 atm
V = 34.3 L
Kinda hard to draw on here...but there are 11 electrons.....2 on first shell, 8 on second and one on outer shell
