Answer:
water vapor
Explanation:
the the answer is water vapor
Le Chatelier's Principle says that when something disrupts the equilibrium, the system adjusts to minimize the effect of that disturbance. If 0.1 M HCl solution is added, this dissociates into H+ and Cl- ions, so there will be more Cl- ions in the system. This causes the reaction to go in the reverse direction (equilibrium shifts to the left) to reduce the amount of Cl-.
Since this also consumes Ag+ ions, the concentration of Ag+ (aq) will decrease.
The answer is the second choice.
Answer:
40 g/mol, Argon
Explanation:
We can find the number of moles of the gas by using the equation of state for an ideal gas:
where
is the pressure of the gas at STP
is the volume of the gas
n is the number of moles
is the gas constant
is the absolute temperature of the gas at STP
Solving for n, we find:
Now we can find the molar mass of the gas, which is given by
where
m = 5.28 g is the mass of the gas
n = 0.132 mol is the number of moles
Substituting,
So, the gas in this problem is Argon, which has a molar mass of 40 g/mol.
Answer:
The correct answer is D
Explanation:
Many substances hold their molecules together in the liquid or solid bosom. This is due, in addition to the pressure and temperature conditions, by the forces of Van der Waals. These are still produced in nonpolar molecules by the movement of electrons through the molecules; in extremely short periods of time, their electrons "charge" towards one end of the molecule, producing small dipoles and keeping the molecules very close to each other.
