When 2.0 g copper is heated with an excess of sulfur, copper (I) sulfide is the product. What is the mass of the copper (I) sulfide produced? (mass to mass)
Answer: Mass is 2.50 g
Explanation: reaction 2 Cu + S ⇒ Cu2S
Amount of Cu = m/M = 2.00 g /63.55 g/mol= 0.03147 mol
Amount of Cu2S = 0.5 n(Cu) = 0.01574 mol
M(Cu2S)= 159.17 g/mol, m = n·M

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?
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 atmIt 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.

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
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.
