Answer:
Water is called the universal solvent because more substances dissolve in water than in any other chemical. This has to do with the polarity of each water molecule. The hydrogen side of each water (H2O) molecule carries a slight positive electric charge, while the oxygen side carries a slight negative electric charge.

Explanation:
#2.
A centigram is 1/100 of a gram, so that means a gram equals 100 centigrams.
Therefore you multiply 72.4 grams by 100/1 (or just 100), and get 7240 cg.
You did that one right but put the wrong unit in the answer. It is is cg ( centigrams).
#3.
1 liter is equal to 1000 milliliters, and I kiloliter is equal to 1000 liters. So one kiloliter is 1000*1000 milliliters or 1,000,000 milliliters.
The conversion factor would be
1/1000000
#4.
1 gigabyte is equal to 10^9 bytes.
I byte is equal to 10^9 bytes.
So 1 gigabyte is 10^9 * 10^9 nanobytes, or 10^18.
The conversion factor would be (1*10^18)/1.
Answer:
22.01J/Kmol
Explanation:
The parameters given in this question are;
Enthalpy (H) = 6.01 kJ/mol.
Number of moles = 1
Entropy change (S) = ?
The formular relationship between entropy and enthalpy is given as;
ΔS=ΔH/T
Temperature for water at freezing point = 0C + 273 = 273 K (converting to Kelvin)
ΔS = 6.01/273
ΔS = 0.0220kJ/Kmol
ΔS = 0.02201 * 1000 = 22.01J/Kmol
Answer:
Carbon
Explanation:
Carbon has the atomic number 6 meaning it has 6 protons and 6 electrons to it will have 6 electrons occupying spherical shaped orbitals
