Explanation:
Note: Molar masses of elements can be found online or in the periodic table.
Moles of Magnesium
= 3.60g / (24.3g/mol) = 0.148mol.
Moles of Chlorine
= 10.65g / (35.45g/mol) = 0.300mol.
Mole ratio of Magnesium to Chlorine
= 0.148mol : 0.300mol = 1 : 2.
Hence we have the empirical formula MgCl2.
Moles of Lithium
= 9.1g / (6.94g/mol) = 1.311mol.
Moles of Oxygen
= 10.4g / (16g/mol) = 0.650mol.
Moles ratio of Lithium to Oxygen
= 1.311mol : 0.650mol = 2 : 1.
Hence we have the empirical formula Li2O.
For this specific problem, these would be the answer to the
following choices:
a. excited
b. ground
c. impossible
I am hoping that these answers have satisfied your queries and
it will be able to help you, thank you and have a nice day.
Answer:
Oils, fats, and certain organic solvents do not dissolve in water because they are hydrophobic.

Answer:
Explanation:
<u>Given the following data;</u>
Number of loops in primary coil, Np = 1 loop.
Number of loops in secondary coil, Ns = 8 loops
Voltage in secondary coil, Vs = 120V
To find the voltage in the primary coil, Vp;
Transformer ratio is given by the formula;
Making Vp the subject of formula;
Substituting into the equation, we have;
Therefore, the voltage in the primary coil, Vp is 15 Volts.
