When ethylene glycol (an antifreeze) is added to water,
the boiling point of the water
A) decreases, and the freezing point decreases
B) decreases, and the freezing point increases
C) increases, and the freezing point decreases
D) increases, and the freezing point increases

Answers

Explanation:

the answer is D they both increase

When ethylene glycol (an antifreeze) is added to water, the boiling point of the water increases, and the freezing point decreases.

What is antifreezer?

Antifreezers are the substance which on mixes with any other compound will decreases the freezing point of that compound.

When we add ethylene glycol which is an antifreeze substance in the water then depression in freezing point takes place but at the same time elevation in boiling point also happen, because they had a great attraction force within themselves.

Decresing in boiling point and freezing point is wrong.Decreasing in boiling point and increasing in freezing point is also wrong.Increasing in boiling point and freezing point is also not possible.

Hence increasing in boiling point and decreasing in freezing point takes place.

Your mommy buys you a helium balloon at the circus. It has a volume of 4.00 liters at STP. What mass of helium, expressed in grams, does this balloon contain?

Answers

Answer:

I believe it will still be 4.00

Explanation:

0.714g of Helium is contained in the balloon

What is STP?

STP stands for standard temperature and pressure. STP refers to a specific pressure and temperature used to report on the properties of matter.

According to IUPAC( International Union of Pure and Applied Chemistry), it is defined as -

Temperature of 0 degree celsius (273K)Pressure of 1 atm

It is generally needed to test and compare physical and chemical processes where temperature and pressure plays an important role as they keep on varying from one place to another.

One mole of a gas under STP conditions occupies a volume of 22.4L.

Given,

Volume = 4L

1 mole of a gas occupies 22.4L of volume at STP.

Thus, 1L of a gas occupies = 1 / 22.4 moles

so, 4 L will occupy = 4 / 22.4 moles

                               = 0.178 moles

Moles = mass / atomic mass

Mass =  moles × atomic mass of He

             = 0.178 × 4

              = 0.714g

Therefore, 0.714g of Helium is contained in the balloon.
