Which of the following is used for purification of water?
a) Sodium bicarbonate
b) Alum
c) Copper sulphate
d) Sodium Hydroxide​

Answers

A. Sodium bicarbonate is a water treatment method used to soften water (removing calcium and magnesium impurities from it) in older water softener systems. The process uses a chemical reaction to convert the calcium hydroxide (or magnesium hydroxide) into calcium carbonate, which isn't water soluble.

B. Alum, also known as potassium aluminum sulfate, can be used to purify water. ... Add 1.4 ounces of alum powder to the contaminated water in the reaction vessel and carefully stir the mixture with the stirring stick for at least five minutes. Sediment will form as the phosphorous in the water binds with the alum powder.

C. If Copper sulphate crystals are added to water it is called 'hydrated copper sulphate solution'.

If it is added to cold water then:-

it is more saturated

but if it is added to warm water then:-

it is unsaturated

and it turns bluish in colour in dissolving in water

D.  Sodium hydroxide is used in the treatment of drinking water to raise the pH of the water to a level that minimizes the corrosion. Raising the pH remains one of the most effective methods for reducing lead corrosion and minimizing lead levels in drinking water.

ありがとう!

Sodium chloride reacts with copper sulfate to produce sodium sulfate and copper chloride. This equation represents a double replacement reaction. Therefore, the correct option is option D.

What is double replacement reaction?

In a double replacement process, the ions in two input ionic compounds are exchanged for the same ions in two new product compounds. When two reactants swap cations or anions to produce two new products, the process is known as a double replacement reaction.

Double displacement reactions and metathesis reactions are other names for double replacement processes. Double replacement reactions include neutralisation, precipitation, and gas production. Sodium chloride reacts with copper sulfate to produce sodium sulfate and copper chloride. This equation represents a double replacement reaction.

Therefore, the correct option is option D.

Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field. ... Electric charge is carried by subatomic particles. In ordinary matter, negativecharge is carried by electrons, and positive charge is carried by the protons in the nuclei of atoms.

Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field. There are two types of electric charge: positive and negative (commonly carried by protons and electrons respectively). Like charges repel and unlike attract. An object with an absence of net charge is referred to as neutral. Early knowledge of how charged substances interact is now called classical electrodynamics, and is still accurate for problems that do not require consideration of quantum effects.

Convert 23 grams of nitrogen dioxide into moles of nitrogen dioxide.

Answers

Answer:

We have to convert the following into moles.

(a) 32 g of oxygen gas = 1 mole

1 gram of oxygen gas = 1/32 mole

Given that 12 g of oxygen gas

No: of moles = given mass / molar mass

= 12 / 32  = 0.375 mole

(b) 18 g of water = 1 mole

1 gram of water = 1/18 mole

Given that 20 g of water

No: of moles = given mass / molar mass

= 20 / 18  = 1.111 mole

(c) 44 g of carbon dioxide = 1 mole

1 gram of CO2 = 1/44 mole

Given that 22 g of carbon dioxide

A student borrows $10,000 from a bank but ends up paying $13,000 on the

loan over the next five years. How much interest did the student pay?

Answers

The student paid an interest of $3,000 over the next five years.

HOW TO CALCULATE INTEREST:

The interest on a borrowed amount of money can be calculated by subtracting the principal from the amount paid over time. That is;

Interest = principal - amount

According to this question, a student borrows $10,000 from a bank but ends up paying $13,000. This means that the principal is $10,000 while the amount is $13,000. The interest is calculated thus;

Interest = $13,000 - $10,000

Interest = $3,000

Therefore, the student paid an interest of $3,000 over the next five years.

A. The nucleus of the atom is unstable.
B. A neutron turns into a proton.
C. A proton turns into an electron.
D. An electron is ejected from the nucleus.

Answers

Answer:

C

Explanation:

When Beta decay happens, the atomic number of an element goes up, and that means there is an extra proton. A is not the answer because unstable atoms cause decay. B is also not correct because this is what happens in Beta decay: a neutron becomes a proton. D is not correct because an electron is actually emitted from the nucleus.
