The moles of I₂ will form from the decomposition of 3.58g of NI₃ is 0.0136 moles.

Moles of any substance will be calculated as:

n = W/M, where

W = required mass

M = molar mass

Given chemical reaction is:

2NI₃ → N₂ + 3I₂

Moles of 3.58g of NI₃ will be calculated as:

n = 3.58g / 394. 71 g/mol = 0.009 moles

From the stoichiometry of the solution, it is clear that:

2 moles of NI₃ = produce 3 moles of I₂

0.009 moles of NI₃ = produce 3/2×0.009=0.0136 moles of I₂

Hence, option (3) is correct i.e. 0.0136 moles.

Mass is the measure of the quantity of the substance present in the sample containing a compound or molecule. The mass of sucrose in the sample is 171 g.

The mass of the compound in the sample is the product of the number of moles of the substance and the molar mass of the compound.

Given,

The molar mass of the sucrose compound = 342.3 g/mol

Number of moles of sucrose = 0.500 moles

Mass of sucrose is calculated as:

[tex]\begin{aligned}\rm mass &= \rm moles \times molar \; mass\\\\&= 0.500 \;\rm moles \times 342.3 \;\rm g/mol\\\\&= 171.15 \;\rm gm\end{aligned}[/tex]

Given the pressure in KPa, the value of the pressure reading in torr obtained is 20.73 torr

101.325 KPa = 760 torr

The value of the pressure in torr can be obtained as illustrated below:

101.325 KPa = 760 torr

Therefore,

2.76324 KPa = (2.76324 × 760) / 101.325

2.76324 KPa = 20.73 torr

Thus, 2.76324 KPa is equivalent to 20.73 torr

Answer:

The formation of double and triple bonds is not as widespread among the atoms of the periodic table as one might expect. At least one of the atoms involved in a multiple bond is almost always C, N, or O, and in most cases both atoms are members of this trio

Covalent bonding occurs when electrons are shared between atoms. Double and triple covalent bonds occur when four or six electrons are shared between two atoms, and they are indicated in Lewis structures by drawing two or three lines connecting one atom to another.

Explanation:

If a geologist drips a small amount of vinegar (acetic acid) onto a sample of dolomite, fizzing will occur because carbon dioxide is produced.

Effervescence observes whenever any gas tried to escape out from an aqueous solution, that's why CO₂ show effervescence.

Reaction between dolomite and acetic acid will be represented as:

MgCO₃ + 2CH₃COOH → CO₂ + H₂O + Mg(CH₃COO)₂

From the above reaction it is clear that carbon dixide gas is produced by showing the effervescence and fizzing behavior.

Yes, we can dissolve 35 moles of KMnO₄ into 500 mL of water to give a molarity of 70 M

Molarity is defined as the mole of solute per unit litre of solution. Mathematically, it can be expressed as:

Molarity = mole / Volume

Molarity = mole / Volume

Molarity = 35 / 0.5

We can not dissolve 35 moles of potassium permanganate into 500 ml of water as it produces the solution with higher molarity than water have.

Molarity of any solution is define as the number of moles of solute present in per liter of the solvent as:

M = n/V

The molarity of the solvent, water, is the highest for aqueous solutions and molarity of 1000g of pure water in 1 liter is 55.5M

Given that,

On putting values, we get

M = 35/0.5 = 70M

Preparation of this solution is impossible.

Hence, KMnO₄ will not dissolve in the water as it produces solution with higher molarity than water.
