The maximum number of electrons that an energy level can hold is determined from the formula 2n^2 equals the total number, where n is the energy level. The first energy level holds 2*1^2=2 electrons while the second holds 2*2^2= 8 electrons.
Magnesium and Oxygen are likely to form an Ionic bond.
Electron has the smallest mass
Answer:
P2= 45.50 atm
Explanation:
If the amount of gas in the tanks remains same we use the equation P1T1=P2T2
40 x 281.15 = P2 x 247.15
P2= 45.50 atm
A) 36.0 x 100 /2 = 1800 g Be
n = m / MM
stoichiometry 1:1
atomic mass of Be= 100 g/ mol
b) theoretical yield
