Answer:
138.39 g/mol
Explanation:
Formula mass is a synonym for molar mass, which is the sum of all the masses of the elements. These can be found on a periodic table.
Because this is hydrated, the formula needs to include H2O.
MgSO4 + H2O
Mg + S + 4O + 2H + O
24.31 + 32.07 + (4*16) + (2*1.008) + 16 = about <u>138.39</u>
Answer:
Ba3(PO4)2
Explanation:
since it's created by giving or taking electrons
Explanation:
Each orbital can only carry at most 2 electrons wih opposite spins.
The first 3 shells are fully filled, giving 9 orbitals.
There is an extra electron in 4s, which gives another orbital. (even though it is not filled yet)
Hence there are 10 orbitals.
Answer:
1.Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.
2.The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma.
3.For every action there is an equal and opposite reaction.
Hope this Helps!

Answer is: dispersion forces.
The London dispersion force is the weakest intermolecular force.
Dispersion force is also called an induced dipole-induced dipole attraction.
The London dispersion force (intermolecular force) is a temporary attractive force between molecules.
The dipole beetween iodine and bromine is weak.
