    Boyles Law deals with what?

    • Pressure and volume

    • Volume and temperature

    • Temperature and pressure

    • Both a and b

    • Both a and c

    Correct Answer
    A. Pressure and volume
    Explanation
    Boyle's Law states that the pressure of a gas is inversely proportional to its volume, given a constant temperature. This means that as the volume of a gas decreases, the pressure increases, and vice versa. Therefore, Boyle's Law deals with the relationship between pressure and volume.

    What is the volume of any gas at STP?

    • 1 mole

    • 1atm

    • 760 torr.

    • Avagadros number

    • 22.4L

    Correct Answer
    A. 22.4L
    Explanation
    The volume of any gas at STP is 22.4L. This is because at standard temperature and pressure (STP), which is defined as 0 degrees Celsius and 1 atmosphere of pressure, one mole of any gas occupies a volume of 22.4 liters.

    Charles’s law deal with?

    • Temperature & pressure

    • Volume& temperature

    • Pressure& volume

    • All of the above

    • None of the above

    Correct Answer
    A. Volume& temperature
    Explanation
    Charles's law states that the volume of a gas is directly proportional to its temperature, assuming that the pressure and amount of gas remain constant. This means that as the temperature of a gas increases, its volume also increases, and vice versa. Therefore, the correct answer is "volume & temperature" as Charles's law specifically deals with the relationship between these two variables.

    Taking away heat favors what reaction?

    • Endothermic

    • Chemical

    • Covalent

    • Exothermic

    • None of the above

    Correct Answer
    A. Exothermic
    Explanation
    Taking away heat favors the exothermic reaction. In an exothermic reaction, heat is released as a product, so removing heat from the system will shift the reaction towards the product side. This is because the reaction wants to counteract the decrease in temperature by releasing more heat. Therefore, taking away heat promotes the exothermic reaction.

    Gay-Lussac’s law deal with?

    • Pressure& volume

    • Volume& temperature

    • Temperature & pressure

    • Both a and b

    • None of the above

    Correct Answer
    A. Temperature & pressure
    Explanation
    Gay-Lussac's law, also known as the pressure-temperature law, states that the pressure of a gas is directly proportional to its temperature, provided that the volume and the amount of gas remain constant. This means that as the temperature of a gas increases, its pressure will also increase, and vice versa. Therefore, Gay-Lussac's law deals with the relationship between temperature and pressure in a gas sample.

    If there is .75 atm of H2, How many mmHG are there?

    • 730MMhg

    • 512MMhg

    • 570MMhg

    • 112MMhg

    • 750MMhg

    Correct Answer
    A. 570MMhg
    Explanation
    The correct answer is 570 mmHg. This is because 1 atm is equal to 760 mmHg, so by converting .75 atm to mmHg, we multiply it by 760. Therefore, .75 atm is equal to 570 mmHg.

  • 8. 

    How many torr. are there if there is 3.5 atm

    • 2945

    • 2740

    • 2720

    • 760

    • 1400

    Correct Answer
    A. 2720
    Explanation
    The given question asks for the conversion of 3.5 atm to torr. The correct answer, 2720, is the conversion factor used to convert atm to torr. 1 atm is equal to 760 torr, therefore 3.5 atm is equal to 3.5 multiplied by 760, which gives us 2720 torr.

    Which way would the equibrium shift for the equation, if you increase the temperature? - ProProfs

    Which way would the equibrium shift for the equation, if you increase the temperature?

    • Shift left

    • Shift right

    • Nothing happens

    • Shift up

    • Shift down

    Correct Answer
    A. Shift left
    Explanation
    Increasing the temperature of a reaction typically causes the equilibrium to shift in the direction that consumes heat, which is the left side of the equation. This is because an increase in temperature is considered as an increase in energy, causing the reaction to favor the endothermic direction in order to absorb the excess heat. Therefore, the equilibrium will shift to the left.
