Answer:A separating funnel is funnel that is used to separate immiscible liquids. Liquids that do not mix with each other are said to be immiscible. Two immiscible liquids, such as oil and water, can be separated by using a separating funnel.
Explanation:
Answer:
Heat of vaporization.
Explanation:
the amount of energy needed to change the specific amount or gram of liquid in to gas phase is called heat of vaporization.
In this liquid is converted into gas phase as because after the boiling point addition of more energy will cause breakage of bonds present in between the liquid molecules which results in the vaporization of liquid.
Carbon dioxide emissions will grow in the next century and global temperatures will increase.
Answer:
V₁ = 228 mL
Explanation:
There is some info missing. I think this is the original question.
<em>A chemist must prepare 575 mL of 50.0 mM aqueous potassium permanganate (KMnO₄) working solution. He'll do this by pouring out some 0.126M aqueous potassium permanganate stock solution into a graduated cylinder and diluting it with distilled water. Calculate the volume in mL of the potassium permanganate stock solution that the chemist should pour out. Round your answer to 3 significant digits.</em>

We want to prepare 575 mL (V₂) of a 50.0 mM solution (C₂). To do so, we start, from a stock solution of concentration C₁ = 0.126 M. In order to find the volume V₁ that the chemist should pour out, we will use the dilution rule.
C₁ × V₁ = C₂ × V₂
0.126 M × V₁ = 50.0 mM × 575 mL
0.126 M × V₁ = 50.0 × 10⁻³ M × 575 mL
V₁ = 228 mL
Answer:
Energy cannot be converted from one form to another.
