Answer:
im not doing your whole homework. but ill give you one cent ;>, whats ur paypal
Explanation:
C. the square root of the mass of the particles.
<h3>Further explanation </h3>
Graham's law: the rate of effusion of a gas is inversely proportional to the square root of its molar masses or
the effusion rates of two gases = the square root of the inverse of their molar masses:

or

From this equation shows that the greater the mass of the gas, the smaller the effusion rate of the gas and vice versa, the smaller the mass of the gas, the greater the effusion velocity.
So if both gases are at the same temperature and pressure, the above formula can apply
Answer: pH = 2.68
Explanation: pH = - log[H3O^+] .
HCl reacts with water : HCl + H2O -> Cl^- + H3O^+
So [H3O^+] = c(HCl) = 0.0021 M
pH = - log(0.0021) = 2.68
Answer:
True
Explanation:
Salt is used to keep ice from forming but it only helps with certain tempuratures is still able to freeze
<span>From left to right:
1) starts at high pH, no buffer zone - strong base being titrated with strong acid
2) starts at low pH, no buffer zone - strong acid being titrated with strong base
3) starts at low pH, shows a buffer zone - weak acid titrated with strong base
4) starts at high pH, shows a buffer zone - weak base titrated with strong acid
5) polyprotic due to two equivalence points
