These isomers occur because they can branch off at the carbon chain. For example, butane has two isomers, C4H10. One of them has a "linear" carbon atom and the other has a branched chain.

Butane is a 4-carbon alkane, so its molecular formula is C4H10. There are two isomers. n-Butane and isobutane. Here, n-butane is a linear compound with four carbon atoms connected by a single covalent bond.

A gas has a mass of 3.82 g and occupies a volume of 0.854 L. The temperature in the laboratory is 302 K, and the air pressure is 1.04 atm. calculate the molar mass of the gas.

1) 93.4 g/ mol
2) 72.3 g/ mol
3) 107 g/ mol
4) 35.8 g/mol

Answers

The molar mass of the gas that has a mass of 3.82 g and occupies a volume of 0.854 L is 106.66g/mol.

How to calculate molar mass?

The molar mass of a substance can be calculated by dividing the mass of the substance by its number of moles.

However, the number of moles of the gas in this question needs to be calculated first using the ideal gas law equation:

PV = nRT

Where;

P = pressureV = volumen = number of molesT = temperatureR = gas law constant

1.04 × 0.854 = n × 0.0821 × 302

0.888 = 24.79n

n = 0.888/24.79

n = 0.036mol

Molar mass of gas = 3.82g/0.036mol

Molar mass = 106.66g/mol

Answers

The new volume of occupied by helium gas when its pressure is increased from 760 mm Hg to 950 mm Hg at an initial volume of 5 L is equal to 4 L.

Boyle's Law

Boyle's law state that at constant temperature, the volume of a fixed mass of gas is directly proportional to its pressure.

To calculate the volume of the helium gas, we use the formula below.

Formula:

P₁V₁ = P₂V₂............. Equation 1

Where:

P₁ = Initial pressureV₁ = Initial volumeP₂ = Final pressureV₂ = Final volume.

Make V₂ The subject of the equation

V₂ = P₁V₁/P₂............... Equation 2

From the question,

Given:

P₁ = 760 mm HgV₁ = 5 LP₂ = 950 mm Hg

Substitute these values into equation 2

V₂ = (760×5)/950V₂ = 4 L.

Hence, The new volume of occupied by helium gas when its pressure is increased from 760 mm Hg to 950 mm Hg at an initial volume of 5 L is equal to 4 L.

Answers

The moles of water are used in the given reaction between CO₂ & H₂O is 12 moles.

How do we calculate mass from moles?

Mass of any substance will be calculated by using their moles as:

n = W/M , where

W = given or required mass

M = molar mass

Given chemical reaction is:

6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

Moles of 528 g of CO₂ = 528g / 44.01g/mol = 11.99 moles

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

6 moles of CO₂ = reacts with 6 moles of H₂O

So, 11.99 moles of CO₂ = reacts with 11.99 = 12 moles of H₂O

Hence option (a)is correct i.e. 12 moles.

Limestone and lime are used in the treatment of acidic soils. what are the advantages and disadvantages of using limestone or lime in the treatment of acidic soil or water bodies?

I WILL GIVE BRAINLIEST!!!

Answers

Answer:

This study is an overview of previous studies on lime (quick and hydrated) -treated soil. Lime is the oldest traditional stabilizer used for soil stabilization. The mechanism of soil-lime treatment involves cation exchange, which leads to the flocculation and agglomeration of soil particles. The high pH environment then causes a pozzolanic reaction between the free Ca+2 cations and the dissolved silica and alumina. Lime-treated soil effectively increases the strength, durability and workability of the soil. Such treatment also improves soil compressibility. A fluctuation behavior was observed on the influence of lime on soil permeability. However, the factors affecting the permeability of the soil-lime mixture should be extensively studied. Nonetheless, lime treatment has a number of inherent disadvantages, such as carbonation, sulfate attack and environment impact. Magnesium oxide/hydroxide are thus proposed as a suitable alternative stabilizer to overcome at least some of the disadvantages of using lime in soil stabilization.
