Answer:
27.03 grams
Explanation:
moles (n) = mass(m)/Molar mass(M)
moles = 1.59
mass = ?
N = 14, H = 1
M(NH3) = 14 + 3(1) = 17
Substitute the values into the equation:
nM = m
∴ m = 1.59 × 17 = 27.03
It is rinsed one last time with the solution to be measured because if there is water in the burret, then it could alter the results. Slightly, but it is still altering it.
The answer is (2) Na2O. Considering these compounds status under room temperature. H2O is liquid. CO2 and SO2 are gas. Na2O is solid. So the Na2O has the highest melting point.
hybridization is defined as mixing up of the atomic orbital with nearly same energies according to linear combination of atomic orbitals. the orbitals formed are equal in energy and are called hybrid orbitals .
