a compound X is formed by an element y which is in the form of pellet. The compound X is also the product of chlor - alkali process. Identify X and Y​

Answers

Answer 1

Answer:

X is sodium hydroxide (caustic soda, NaOH)

y is sodium (Na)

Explanation:

The process of industrial electrolysis of sodium chloride solution by which chlorine and sodium hydroxide (caustic soda) can be produced is known as the chlor-alkali process as follows;

2NaCl + 2H₂O → Cl₂ + H₂ + 2NaOH

Given that the compound X is formed from a element y which is in the form of a pellet, we have;

The element in the above reaction that can exist as pellet is the silver white metallic sodium pellet

Therefore, the compound X is NaOH and the element y is sodium, Na.

Magnesium reacts with fluorine to form magnesium fluoride. Which diagram shows the correct arrangement of electrons in the product?

Answers

Answer:

Diagram B shows the correct arrangement of electrons in the product.

Magnesium reacts with fluorine to form magnesium fluoride two electrons of magnesium are transferred to the 2 atoms of fluorine and fluorine is the most electronegative element of the periodic table. Option C is correct.

What is electronegativity?

Electronegativity is the tendency or power of an atom to attract the electrons from the metals they are mostly nonmetals and want to complete their octave too.

The most electronegative elements of the periodic table are oxygen, nitrogen, and fluorine, as they are always willing to complete the octave, and fluorine will take electrons from magnesium.

Therefore, Option C is correct if the 2 atoms of fluorine and fluorine are the most electronegative element of the periodic table. Magnesium reacts with fluorine to form magnesium fluoride two electrons of magnesium are transferred.

Which of the following describes what happens in a chemical reaction?
O A. Molecules change from one phase to another.
B. Molecules dissolved in solution are separated again.
O c. Chemical bonds are broken, and new ones are formed.
O D. Molecules mix without rearranging atoms.

Answers

Answer:

c. Chemical bonds are broken, and new ones are formed.

Explanation:

Hope this helps. :)

In a chemical reaction, chemical  bonds are broken, and new ones are formed.

What is a chemical reaction?

Chemical reactions are defined as reactions which occur when a substance combines with another substance to form a new substance.Alternatively, when a substance breaks down or decomposes to give new substances it is also considered to be a chemical reaction.

There are several characteristics of chemical reactions like change in color, change in state , change in odor and change in composition . During chemical reaction there is also formation of precipitate an insoluble mass of substance or even evolution of gases.

There are three types of chemical reactions:

1) inorganic reactions

2)organic reactions

3) biochemical reactions

During chemical reactions atoms are rearranged and changes are accompanied by an energy change as new substances are formed.

how many atoms are in 2.10 g of K? molar mass of K=39.10g/mole.

Answers

Answer:

The answer is option B

Explanation:

To calculate the number of atoms we must first calculate the number of moles

Molar mass = mass / number of moles

number of moles = mass / Molar mass

Molar mass (K) = 39.10mole

mass = 2.10g

number of moles = 2.10/ 39.10

= 0.0537mol

After that we use the formula

N = n × L

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10^23 entities

Number of K atoms is

N = 0.0537 × 6.02 × 10^13

N = 3.23×10^22 atoms of K
