A. all magnets have two poles
Answer:
The three definitions are listed in the explanation.
Explanation:
A nonelectrolyte is a molecular compound that does not consist of ions hence it does not dissociate into ions in solution.
A weak electrolyte is a soluble ionic compound that dissociates only to very small extent into ions in solution.
A strong electrolyte is a soluble ionic compound that dissociates completely into ions when dissolved in water.
Answer:
The independent variable in this experiment is what he feeds the chickens (rice or corn).
Explanation:
The independent variable is the variable the experimenter manipulates or changes.
Answer : The unit of 
in mol/L.mm Hg is, 
Explanation :
As we know that the is the Henry's Law constant for argon at 
is, 
Now we have to determine the unit of in mol/L.mm Hg
Conversion used for pressure from atm to mmHg is:
1 atm = 760 mmHg
So,
Thus, the unit of in mol/L.mm Hg is,
5.5 grams of reactants. According to the Law of Conservation of Mass, mass isn’t created or lost through any chemical changes, so the total mass should remain constant from the initial reactants to the final products.
