A 25.5 liter balloon holding 3.5 moles of carbon dioxide leaks. If we are able to determine that 1.9 moles of carbon dioxide escaped before the container could be sealed, what is the new volume of the container?

Answers

Answer: The new volume of the container is 13.8 L

Explanation:

To calculate the new volume of the system, we use the equation given by Avogadro's Law. This law states that volume of the gas is directly proportional to the number of moles of the gas at constant pressure.

Mathematically,

$(V_1)/(n_1)=(V_2)/(n_2)$

where,

$V_1\text{ and }n_1$ are the initial volume and moles of the gas.

$V_2\text{ and }n_2$ are the final volume and moles of the gas.

We are given:

$V_1=25.5L\nn_1=3.5\nV_2=?\nn_2=1.9$

Putting values in above equation, we get:

$(25.5)/(3.5)=(V_2)/(1.9)\n\nV_2=13.8L$

Thus the new volume of the container is 13.8 L

Ethanol contains the elements carbon, hydrogen, and oxygen. When ethanol burns, it chemically reacts with oxygen gas. C2H6O + O2 ethanol oxygen gas What elements will be present in the substances that are created when ethanol burns?

Answers

Answer:

The elements that will be present after the burning of Ethanol are;

(i) Carbon

(ii) Oxygen

(iii) Hydrogen

Explanation:

The balanced chemical equation for the burning of ethanol is as follow;

C₂H₅OH + 3 O₂ → 2 CO₂ + 3 H₂O

It can be observed in given balanced chemical equation that there three elements involved in this entire reaction. The elements that present in the reactant side are also found on the product side. It means that the elements have just rearranged going from reactant to product.

This means that this reaction is obeying Law of Conservation of Mass which states that mass can neither be created nor destroyed but it can be changed from one form to another hence, to keep the mass on both sides of the reaction balanced the same elements should be present on the product side too.

Answer: carbon, hydrogen, and oxygen only

Explanation: When a chemical reaction occurs, the atoms in the original set of substances are rearranged to form a new set of substances. The number of atoms of each element does not change.

The elements carbon, hydrogen, and oxygen are the only elements present in the original substances, so the only elements in the final substances after the reaction will be carbon, hydrogen, and oxygen, as well. The number of atoms of each element must be the same before and after the reaction.

Why is crushed ice used for snow cones? a) decreasing the pressure helps dissolve more flavoring
b) increasing the temperature helps dissolve more flavoring
c) increasing the surface area helps dissolve more flavoring
d) decreasing agitation helps dissolve more flavoring

Answers

The reason for crushing ice for snow cones is C) increasing the surface area helps dissolve more flavoring. The amount of flavoring absorbed depends on the temperature and the surface area of contact. Because the temperature can not be increased without melting the ice, the ice is crushed. This increases its surface area and more flavoring is dissolved.

The answer to the question is C, increasing the surface area helps dissolve more flavoring. The motivation behind why squashed ice utilized for snow cones is a direct result of expanding the surface range breaks down all the more enhancing. The snow cone is a cone-molded paper glass that contains little bits of ice enhanced with a sweet syrup.
