The answer would be Rocks, metals, hydrogen compounds, hydrogen and helium, all in gaseous form.
It has a positive charge. 22-18= +4. you just have to subtract the electrons from the protons. if you get a positive number your charge is positive if you get a negative number the charge is negative.
Answer:
the work done on the gas is 4,988.7 J.
Explanation:
Given;
number of moles of the monoatomic gas, n = 4 moles
initial temperature of the gas, T₁ = 300 K
final temperature of the gas, T₂ = 400 K
The work done on the gas is calculated as;
For monoatomic ideal gas:
Where;
R is ideal gas constant = 8.3145 J/K.mol
Therefore, the work done on the gas is 4,988.7 J.
Answer:
Benzoic acid and sodium benzoate are members of a family of food additives whose ability to the rate at which food spoils has helped produce a 10-fold decrease in the incidence of stomach cancer. To save time and space, we'll abbreviate benzoic acid as HOBz and sodium benzoate as NaOBz. Benzoic acid, as its name implies, is an acid.
