According to Coulomb’s law, what will happen to the electric force between

two identical negative charges as they move closer together?

A. Fe will become negative and decrease in magnitude.

O B. Fe will stay negative and increase in magnitude.

C. Fe will stay positive and increase in magnitude,

D. Fe will become positive and decrease in magnitude.

Answers

Answer 1

Answer:

C. Fe will stay positive and increase in magnitude.

Explanation:

Coulomb's law states that the force of attraction of repulsion between two charged particles is directly proportional to the magnitude of their charges and inversely proportional to the square of the distance of separation between them.

This means that if the size of the charges are large, the force acting on them will be large as well. Also if the distance between the two charges increases the force decreases. However, the force increases when the distance of separation decreases.

Like charges repel, therefore, two negative charges brought together will repel each other, and the distance between the two charges decreases, the force will increase in magnitude. Forces of repulsion are considered positive, therefore, the force, Fe, will stay positive and increase in magnitude.

Answer:

d

Explanation:

check if one element replaces another element in a compound

The single replacement reaction can be identified when there has been the replacement of one element with another element in the compound. Thus, option C is correct.

The replacement reaction can be defined as the reaction in which the highly reactive element replaced the low reactive element in the reaction and forms a compound.

The reaction has been given as:

X + AY [tex]\rightarrow[/tex] AX + Y

The X has been highly reactive than Y replaces Y in the compound and forms the compound AX.

The single replacement reaction can be identified when there has been the replacement of one element with another element in the compound. Thus, option C is correct.

Salt particles will move toward the left through diffusion.
Salt particles will move toward the left through active transport.
Salt particles will move toward the right through diffusion.
Salt particles will move toward the right through active transport.

Answers

Answer: Hope it may help you

Explanation:

Diffusion can be defined as the movement of particles from a region where there a more concentration of solute to the region having less concentration of the solute.

Here, the salt particles will move from right side of the box to the left side of the box.

This is because the right side has more particle and the left side has less particles so they will move towards the left side.

A 200.0-mL sample of helium gas is in a cylinder with a movable piston at 110 kPa and 275 K. The piston is pushed in until the sample has a volume of 95.0 mL. The new temperature of the gas is 310. K. What is the new pressure of the sample?

51.1 kPa
261 kPa
249 kPa
274 kPa

Answers

Answer:

P₂ = 261 KPa

Explanation:

Given data:

Volume of sample = 200 mL

Initial pressure = 110 KPa

Initial temperature = 275 K

Final volume = 95 mL

Final temperature = 310 K

Final pressure = ?

Solution:

Formula:

P₁V₁/T₁ = P₂V₂/T₂

P₂ = P₁V₁T₂ /T₁ V₂

P₂ = 110 KPa× 200 mL× 310 K /275 K  × 95 mL

P₂ = 6820000 KPa / 26125

P₂ = 261 KPa

7. Calculate the average atomic mass of bromine. One isotope of bromine has an atomic mass of 78.92amu and a relative abundance of 50.69%. The other major isotope of bromine has an atomic mass of 80.92amu and a relative abundance of 49.31%.

Answers

Answer:

Average atomic mass  = 79.9 amu.

Explanation:

Given data:

Average atomic mass of Bromine = ?

Atomic mass of 1st isotope = 78.92 amu

Relative abundance of 1st isotope = 50.69%

Atomic mass of 2nd isotope = 80.92 amu

Relative abundance of 1st isotope = 49.31%

Solution:

Average atomic mass = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass)  / 100

Average atomic mass  = (50.69×78.92)+(80.92×49.31) /100

Average atomic mass =  4000.45 + 3990.16 / 100

Average atomic mass  = 7990.61 / 100

Average atomic mass  = 79.9 amu.

D. formation of zinc from zinc sulphide ​

Explanation:

A redox reaction could be explained as an artificial reaction in which electrons are moved between two reactants partaking in it. This substitution of electrons can be recognized by examining the variations in the oxidation states of the reacting classes. The generation of hydrogen fluoride is an illustration of a redox reaction. We can crack the reaction down to investigate the oxidation and loss of reactants.

Arrange the following in order of increasing atomic radius: Mg, Na, P, Si, and Ar.

Answers

Answer:

Ar, P, Si, Mg, Na

Explanation:

Ar=106pm

P=107pm

Si=111pm

Mg=141pm

Na=166pm

Na>Mg>Si>P>Ar is the order of increasing atomic radius.

What are elements?

Elements are the simplest substances which cannot be broken down using chemical methods.

Atomic radii vary in a predictable way along or across the periodic table. The atomic radius increases from top to bottom in a group, and decreases from left to right across a period. Thus we can say that helium is the smallest element, and francium is the largest.

Ar=106pm

P=107pm

Si=111pm

Mg=141pm

Na=166pm

Hence, Na>Mg>Si>P>Ar is the order of increasing atomic radius.
