Which of the following leads to a lower rate of diffusion? A. Heated gas
B. Lower molar mass of particles
C. Higher velocity of particles
D. Reduced temperature

Answers

Answer 1
Answer:

Reduced temperature leads to a lower rate of diffusion. Hence, Option (D) is the correct answer.

What is Diffusiion ?

Diffusion is the net movement of anything generally from a region of higher concentration to a region of lower concentration.

Diffusion is driven by a gradient in Gibbs free energy or chemical potential.

Therefore, Reduced temperature leads to a lower rate of diffusion. Hence, Option (D) is the correct answer.

A solid-state component with three layers of semiconductors is a

Answers

A solid-state component with three layers of semiconductors is a transistor. 

Answer: A solid-state component with three layers of semiconductors is a transistor.

Explanation:

A device with the help of which current or voltage is regulated and for electronic signals it acts as a switch or gate is known as a transistor.

A transistor has three layers of semiconductors. Each of these layers are capable of carrying current.

Thus, we can conclude that a solid-state component with three layers of semiconductors is a transistor.


Given the equation representing a reaction at equilibrium: N2(g) + 3H2(g) 2NH3(g) What occurs when the concentration of H2(g) is increased?

Answers

Given the equation representing a reaction at equilibrium: N2(g) + 3H2(g) = 2NH3(g). When the concentration of the hydrogen gas is increased, the equilibrium will tend to go to the products or to the forward reaction. Therefore, more products are formed.

Which element, represented by X, reacts with fluorine to produce the compound XF2?

Answers

Elements in Group 2 of the periodic table.

The percentage by mass of Br in the compoundAlBr3 is closest to
(1) 10.% (3) 75%
(2) 25% (4) 90.%

Answers

Answer: The correct answer is option(4).

Explanation:

Molar mass of the aluminium bromide, AlBr_3=266.69 g/mol

Atomic mass of bromine = 79.90 g/mol

Percentage of Mass of bromine in AlBr_3:

\% Br\text{ by mass}=\frac{\text{Atomic mass of Br}* \text{Number of Br atoms}* 100}{\text{Molar mass of }AlBr_3}

\% Br\text{ by mass}=(79.90 g/mol* 3* 100)/(266.69 g/mol)=89.97\%\approx 90\%

Hence, the correct answer is option(4).

What you have to do it find the percentage / solve it. Divide the mass by the entire mass. 
239.7 ÷ 266.68 = 0.898 × 100 = 90% Br.

A researcher is using a particle accelerator in an experiment studying isotopes. How can the researcher change one isotope into a different isotope of the same element?by removing valence electrons

by adding valence electrons

by adding or removing protons

by adding or removing neutrons

Answers

The researcher can change one isotope into a different isotope of the same element by adding or removing neutrons. This is because, isotopes are two or more forms of an element which contain equal number of protons and electrons but different number of neutrons. Isotopes differ in relative atomic mass but have same chemical properties.

Answer: by adding or removing neutrons

Explanation:
