The units of molarity are moles per liter; therefore, in order to compute the molarity, we must first find the moles of potassium perchlorate and the volume in liters:
Moles = mass / molecular mass
Moles = 18.4 / 138.6
Moles = 0.13 mol

Volume = 300 mL
1 L = 1000 mL
Volume = 0.3 mL

Molarity = moles / liters
Molarity = 0.13 / 0.3
Molarity = 0.43 M

A solution is prepared by dissolving 0.23 mol of benzoic acid and 0.27 mol of sodium benzoate in water sufficient to yield 1.00
Monica [59]

Answer:

The pH does not decrease drastically because the NaOH reacts with the <u>D) Benzoic acid</u> present in the buffer solution.

Explanation:

The hydroxide ions will react with acidic part of the solutions, it means the benzoic acid, so it will form the conjugate base, the benzoate ion.

If Jerome is swinging on a rope and transferring energy from gravitational potential energy to kinetic energy, _____... is being
Pachacha [2.7K]

<u>Answer;</u>

-Work

If Jerome is swinging on a rope and transferring energy from gravitational potential energy to kinetic energy, <u>work </u> is being done.

<u>Explanation;</u>

  • Work refers to the application of a given force over a distance. Thus, we can say work is the product of force and distance.
  • Energy on the other hand is the ability of a body to change, its location, shape, or state of another body.
  • According to the work-Energy principle, a change in the kinetic energy, which is the energy possessed by a body in motion, is equivalent to the net work done on the body.

Can someone help with this please?
Aleks04 [339]
I think the answer would be yes. if my math is correct 84,596 divided by 29 equals 2,917 sickles. 2,917 sickles is equal to 172 galleon. therefore he would have enough to buy the 70 galleon broomstick. hopefully i did this right and it helped!
