What mass of ethanol will All
a 250.0 ml container if its
density is 0.789 g/ml?

Answers

Answer:

The answer is 197.25 g

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

mass = Density × volume

From the question

volume = 250 mL

density = 0.789 g/ml

So we have

mass = 250 × 0.789

We have the final answer as

197.25 g

Jose adds five grams of a chemical to one liter of liquid and observes a reaction. If the reaction is endothermic, what will happen?
A
The liquid's mass increases; therefore, the volume of the liquid will increase
B
The liquids' mass decreases; therefore, the volume of the liquid will decrease.
С
Energy is released during the reaction; therefore, the temperature of the liquid will increase.
Energy is absorbed during the reaction; therefore, the temperature of the liquid will decrease.
D

Answers

Answer:

D. Energy is absorbed during the reaction; therefore, the temperature of the liquid will decrease

Explanation:

In a chemical reaction, the reaction is said to be ENDOTHERMIC if the reaction utilizes or uses energy instead of given it off. In this reaction, Jose adds five grams of a chemical to one liter of liquid and observes the reaction.

According to this question, the reaction is ENDOTHERMIC. This means that energy is absorbed or used up during the reaction; therefore, the temperature of the liquid will decrease i.e. the liquid used in the reaction will become COLDER.

How can charged objects interact without touching

Answers

Electrostatic forces are non-contact forces; they pull or push on objects without touching them. Rubbing some materials together can result in something called 'charge' being moved from one surface to the other. Charged objects pull on other uncharged objects and may either push or pull on other charged objects(hopefully this helps)
