What is the difference between a strong electrolyte and a weak electrolyte

This element is in group 1.

According to the octet rule, this element would be expected to form an ion with a charge of +1.

If X is in period 5, the ion formed has the same electron configuration as the noble gas Krypton

The symbol for the ion is Rb⁺

Electronic configuration refers to the arrangement of electrons in the orbitals of an atom or molecule, indicating the energy level of the electrons, the number of electrons in each energy level, and the number of electrons in each orbital.

Considering the given element:

It has one valence electron, hence it is in group 1. Group 1 elements form ions with a charge of +1.

Losing one electron will give the ion the same electron configuration as Kyrton since it is the noble gas in Period 4.

The element is rubidium and the ion is Rb⁺.

Because when heated, it releases carbon dioxide gas, which is responsible for the rising of cookies, doughnuts, and bread.

The temperature at which a solid transforms into a liquid at atmospheric pressure is referred to as the liquid’s melting point.

The fact that water boils at a greater temperature than fluorine makes option C the correct choice. The melting point of water is zero degrees Celsius (32 degrees F). Depending on the atmospheric pressure, different amounts of water will boil at different temperatures. When purified water reaches its boiling point at sea level, it does so at 212 degrees Fahrenheit (100 degrees Celsius).

Compared to fluorine, water has a greater boiling point. Regarding the melting and boiling points of water and fluorine molecules, this statement is accurate.

The temperature at which a substance's solid and liquid phases are in equilibrium is known as its melting point. A temperature at which a substance's vapour pressure reaches its boiling point.

Explanation:

The question gives us the following balanced equation:

H2SO4 + 2NaOH → Na2SO4 + 2H2O

The equation tells us that 1 mole of H2SO4 react with 2 mole of NaOH producing 1 mole of Na2SO4 and 2 moles of H2O.

It is important to know the ratio between sodium sulfate and water: 1:2.

Also, the question tells us the quantity in grams of Na2SO4. We need to transform it to moles, using the following formula:

n = m/MM

MM of Na2SO4 = 142.04 g/mol

so:

n = 2/142.04

n = 0.0014 moles of Na2SO4

The ratio between Na2SO4 and H2O is:

1 mole of Na2SO4 ---- 2 moles of H2O

0.0014 moles of Na2SO4 ---- y

y = 0.0028 moles of H2O

Answer: It is produced 0.0028 moles of H2O.

Explanation:

Sulfuric acid is prepared industrially by means of the response of water with sulfur trioxide which in turn is made by way of a chemical combination of sulfur dioxide and oxygen both by way of the touch system or the chamber system.

                         H2SO4 (l) H2O (g) + SO3 (g).

The reaction is highly exothermic as an enormous amount of heat is liberated.

The usual approach is to dilute the sulfur trioxide in sulphuric acid. This produces oleum. SO3 (g) + H2SO4 → H2S2O7 (1) Oleum can be in addition diluted in water to acquire concentrated sulphuric acid.

An acid catalyst is added to protonate the carbonyl carbon. How does this catalyze the response, robust acid catalysts catalyze the hydrolysis and transesterification of esters which enables the mechanism with a view to boom the electrophilicity of the carbonyl carbon to assist protonate the carbonyl oxygen.

Molar mass P2O5 = 31 x 2 + 16 x 5 => 142 g/mol

142 g ---------------- 6.02 x 10²³ molecules

0.930g g ------------ ( molecules )

molecules = 0.920 x ( 6.02 x 10²³ ) / 142

molecules = 5.53 x 10²³ / 142

= 3.89 x 10²¹ molecules

1 molecule P2O5 -------------------------- 7 atoms

3.89 x 10²¹ molecules -------------------- ( atoms )

atoms = ( 3.89 x 10²¹) x 7 / 1

2.72 x 10²² atoms of P₂O₅ are there in 0.930 g of  P₂O₅.

Molar mass P₂O₅ = 31 x 2 + 16 x 5 => 142 g/mol

142 g atoms are present in 6.02 x 10²³ molecules

Therefore, total number of molecules in 0.930g of atoms is calculated as-

molecules = 0.930 x ( 6.02 x 10²³ ) / 142

molecules = 5.53 x 10²³ / 142

= 3.89 x 10²¹ molecules

1 molecule of P₂O₅ contains 7 atoms

Therefore, the number of atoms in 3.89 x 10²¹ molecules is calculated as

Lipids are fatty, waxlike molecules found in the human body and other organisms. They serve several different roles in the body, including fueling it, storing energy for the future, sending signals through the body and being a constituent of cell membranes, which hold cells together.

Explanation:

In biology and biochemistry, a lipid is a macrobiomolecule that is soluble in nonpolar solvents. Non-polar solvents are typically hydrocarbons used to dissolve other naturally occurring hydrocarbon lipid molecules that do not dissolve in water, including fatty acids, waxes, sterols, fat-soluble vitamins, monoglycerides, diglycerides, triglycerides, and phospholipids.

To solve such type of question we must be knowing the concept behind the ideal gas equation. The final pressure of the gas mixture after the addition of the Ar gas is 2.25 atm

Ideal gas equation is the mathematical expression that relates pressure volume, temperature and number of moles of gas

Mathematically,

PV=nRT

according to question T and V is constant

P ∝ n

P₁/n₁= P₂/n₂

Where

P₁ = initial pressure= 0.75atm

P₂ = Final pressure=?

n₁= number of moles of gas initially present=n

n₂ = Final moles of gas present=2n

Substituting into the given equation

P₂= P₁n₂/n₁

P₂ = 0.75atm ×2n/n

P₂ = 1.5 atm

The total pressure of the gas=partial pressure of N2 +  partial pressure after addition of Ar = 0.75 atm + 1.5 atm = 2.25 atm

The final pressure of the gas mixture after the addition of the Ar gas is 2.25 atm

Explanation: 1 mole of NaOH is equal to 40 g, so we can start setting up the equation by saying that 52 g NaOH= 1 mole/40 g.
