It is a liquid because when you have a liquid, there is no definite shape. Therefore, this would be the answer because it takes the shape of its container.
Final answer: a. Liquid
Answer: C) 2,2
Explanation: In the product H2O2, there are 2 hydrogen atoms and 2 oxygen atoms. H2O has two hydrogen atoms, but not oxygen atoms. So to balance the equation we add the coefficient 2 in front of H2O. Then we also have to add a coefficient 2 in front of H2O2 in order to balance it out.
Hope this helps :)
Hydrocarbons are only made up of carbon and hydrogen. since this compound has chlorine, it is not a hydrocarbon
Answer:
10^-14 / [H3O+]
Explanation:
Hydronium (H3O+) and hydroxide ions (OH-) are both present in pure water and in all aqueous solutions.
Their respective concentrations in water are 10^-7 M each and are inversely proportional to each other as given by the ion product of water, Kw.
Kw = [H3O+][OH−]
Where Kw = 1.0 * 10^-14,
[H3O+] = concentration of hydronium ions
[OH-] = concentration of hydroxide ions
Therefore, [OH-] = Kw / [H3O+]
[OH-] = 10^-14/[H3O+]
If T=const
P1V1=P2V2
P1*4L=P2*1L
P2=4P1
pressure increases by factor of 4
