According to modern atomic theory, the exact location of a(n) ____________________ is uncertain.

Answers

Answer 1

Answer: The correct answer is electrons. According to the modern atomic theory, the exact location of an electron is uncertain. But the region in which there will be high in probability of finding an electron is in the orbitals of the electron cloud.

Answer 2

Answer:

is going to be electrons

Most plants and all animals depend on _____ to meet their need for nitrogen.lightning strikes
denitrifying bacteria
bacteria that break apart cellulose
nitrogen-fixing bacteria

Answers

Answer: nitrogen fixing bacteria

Explanation:

Most plants and animals are dependent on nitrogen fixing bacteria for their nitrogen requirements. As they are incapable of absorbing the atmospheric nitrogen directly. The soil bacteria traps the atmospheric nitrogen convert it into forms like ammonia, nitrates and nitrites which are readily absorbed by the plants and some soil borne animals.

They depend on nitrogen-fixing bacteria, which convert atmospheric nitrogen into a usable form.

As the temperature of a chemical reaction in the gas phase is increased, the rate of the reaction increases because(1) fewer particle collisions occur
(2) more effective particle collisions occur
(3) the required activation energy increases
(4) the concentration of the reactants increases

Answers

Answer: option (2) more effective particle collisions occur.

Justification:

Always keep in mind that the temperature is a measure of the average kinetic energy of the particles.

The higher the temperarute the hiigher the kinetic energy.

Also, remeber that the kinetic energy is the energy of motion: the higher the kinetic energy the hgher the speed of the particles and the more energetic the collisions.

Therefore, those more energetic collisions will increase the number of collisions that overcome the activiation energy leading to higher rate of conversion (reaction), whic is what a more effective particle collisions occur mean.

When the compound, Na2S, is mixed with water, the Na2S is:soluble because all Na+1 compounds are soluble in water

insoluble because most Na+1 compounds are insoluble in water

soluble because all S−2 compounds are soluble in water

insoluble because there are no water soluble S−2 compounds

Answers

Answer: Option (a) is the correct answer.

Explanation:

Atomic number of sodium is 11 and its electronic distribution is 2, 8, 1. Whereas atomic number of sulfur is 16 and its electronic distribution is 2, 8, 6.

So, when both sodium and sulfur chemically combine together then it results in the formation of an ionic bond due to transfer of an electron from sodium to sulfur atom.

Sodium changes into $Na^(+)$ by losing an electron and sulfur changes into $S^(2-)$ by gain of two electrons from two sodium atoms.

As it is known that water is a polar solvent and all ionic substances will dissolve in water.

Therefore, we can conclude that when the compound, $Na_2S$ , is mixed with water, the $Na_2S$ is soluble because all $Na^(+1)$ compounds are soluble in water.

When the compound, Na2S, is mixed with water, the Na2S is soluble because all Na+1 compounds are soluble in water. The rest of the choices do not answer the question above.

If the pressure P applied to a gas is increased while the gas is held at a constant temperature, then the volume V of the gas will decrease. The rate of change of the volume of gas with respect to the pressure is proportional to the reciprocal of the square of the pressure. Which of the following is a differential equation that could describe this relationship?

Answers

The differential relationship has been $\rm \bold{(dV)/(dP)\;=\;(C)/(P^2)}$ .

The gas has been termed to be the ideal gas. For an ideal gas at a constant temperature, the relationship of the change in pressure and volume can be given as constant. The relationship has been given with the application of Boyle's law.

The product of the pressure and volume has been a constant quantity for a reaction.

Pressure $*$ Volume = Constant
