What happens to a glass of pure fruit juice when water is added to it?

A - The number of moles of fruit juice increases.
B - The number of moles of fruit juice decreases.
C - The molarity of the juice increases.
D - The molarity of the juice decreases.

Answers

D. The MOLARITY of the juice DECREASES when water is added to it.

MOLARITY refers to the amount of a substance (solute) in a certain volume of solution. It is a measure of the CONCENTRATION OF A SOLUTION. In chemistry, molarity is calculated by dividing the number of moles of a solute by the volume of the solvent i.e.

MOLARITY (mol/L or M) = number of moles (n)/volume of solvent (V)

* The above equation means that the molarity of a solution is inversely proportional to its volume i.e. as molarity increases, volume decreases and vice versa.

According to this question, water is added to a glass of pure fruit juice (dilution). This means that the volume of the juice will increase. As the volume increases via addition of water, the MOLARITY DECREASES.

Electronic configuration, also called electronic structure or electron configuration, the arrangement of electrons in orbitals around an atomic nucleus.

The electron configuration of an element describes how electrons are distributed in its atomic orbitals.

Electron configurations of atoms follow a standard notation in which all electron-containing atomic subshells (with the number of electrons they hold written in superscript) are placed in a sequence.

Silicon belongs to group 14th and 3rd period.Therefore, The electron configuration for silicon is  [Ne] 3s² 3p². Hence Option (C) is correct.

Below!

Explanation:

Isotopes are elements with a similar chemical makeup and the same atomic number, but a different atomic mass and number of neutrons . An example of this would be carbon-12, carbon-13, and carbon-14. Three isotopes of the element carbon that have the same 6 protons but have a different neutron count. A simple way to explain isotopes would be to say that they are just different "versions" of an element.

Write down a step by step process of finding the volume of CO₂ produced during the fermentation of C₆H₁₂O₆ at STP.

Answers

Answer:

Step 1: Write a balanced chemical equation of the reaction

Step 2: Convert the mass of glucose given to moles of glucose by dividing with the molar mass of glucose, 180 g/mol:

Step 3: Using the mole ratio in the equation of reaction, determine the moles of CO₂ produced:

Step 4: Convert moles of CO₂ to volume in litres of CO₂ at STP:

Explanation:

Fermentation is a complex chemical process whereby microorganisms such as yeast are used in converting carbohydrates such as glucose into ethanol and carbon dioxide under anaerobic conditions:

Step 1: Write a balanced chemical equation of the reaction

Theequation of the fermentation of glucose, C₆H₁₂O₆ at STP is as follows:

C₆H₁₂O₆ (aq) ----> 2 C₂H₅OH (l) + 2 CO₂ (g)

Step 2: Convert the mass of glucose given to moles of glucose by dividing with the molar mass of glucose, 180 g/mol:

Moles of glucose = mass of glucose given/molar mass of glucose = x g/ 1180 g/ mol = x moles of glucose

Step 3: Using the mole ratio in the equation of reaction, determine the moles of CO₂ produced:

From the equation of reaction, 1 mole of C₆H₁₂O₆ produces 2 moles of CO₂.

Therefore, x moles of C₆H₁₂O₆ will produce 2x moles of CO₂

Step 4: Convert moles of CO₂ to volume in litres of CO₂ at STP:

1 mole of a gas at STP has a volume of 22.4 L

1 mole of CO₂ has a volume of 22.4 L

2x moles of CO₂ has a volume of 2x × 22.4 L

9. Which is true of a radioisotope that is used to date rock formations?

Answers

Answer:

Radiometric dating or radioactive date is the method that uses radioisotope to date the formation of a rock. The age of the rocks will be determined.

Explanation:

Radioactive deterioration is a natural process and results from the unstable atomic core, which releases bits and parts.

These radioactive particles are released as (there are many types). This decline process results in a more equilibrated nucleus, which makes the atom stable when the number of protons and neutrons balances.

This radioactivity is suitable for dating, as a radioactive "parent" item is constantly decaying into a stable "daughter" element.

A single mineral grain or a whole rock may be dated. There are techniques by which the sample is excited in a nuclear reactor and then measured with a mass spectrometer. The isotope (such as in the argon-argon scheme).

Others put mineral grains under a special microscope, fir in the grains with an ionising laser beam that releases the mineral and the isotopes.

The isotopes are measured by a mass spectrometer inside the same machine (an example of this is SIMS analysis).

An aqueous solution contains
32.7% KCl (weight/weight %).

How many grams of water (H20) are contained in 100 g of this solution?

Answers

Answer:

67.3g

Explanation:

%(w/w) = mass of solute/total mass of solution × 100

According to this question, an aqueous solution contains 32.7% KCl (w/w%). Firstly, we find the mass of the solute (KCl) as follows, if the mass of solution is 100g:

32.7 = mass of solute/100 × 100

mass of solute (KCl) = 32.7g

Mass of solution = mass of solvent (water) + mass of solute (KCl)

100g = x + 32.7g

x = 100 - 32.7

x = 67.3

Hence, the mass of water contained in the 100g solution is 67.3g.

Answer:

D. C₄H₁₀ + 6.5O₂ → 4CO₂ + 5H₂O + heat

Explanation:

The reaction of the combustion of isobutane with oxygen is presented as follows;

In the above reaction, the number of elements on the reactant side are;

4 carbon, C, atoms, 10 hydrogen, H, atoms, and 13 oxygen, O, atoms

The number of elements on the product side of the above chemical reaction are;

The number of carbon atoms, C = 4
