Inner shell electrons are not shared between atoms when they form
chemical bonds.
1.TRUE
2.FALSE
Answers
Yes, the statement is true because chemical bonds formed by sharing or transferring outermost electrons of an atom.
Why inner shells are not shared?Inner shell electrons are not shared between atoms when they form chemical bonds but the outermost electrons can form bonds with the atoms because they are easy to lose and share.
So we can conclude that the statement is true because chemical bonds formed by sharing or transferring outermost electrons of an atom.

Answers
Answer: A. Catalyst
Explanation:
An catalyst is used to speed up the rate of the reaction. In a biochemical reaction an enzyme is the only catalyst which is exposed to the reactant forming the enzyme substrate or reactant complex thus forming the product. The catalyst increases the product formation from the reactant by increasing the pace of the reaction. Catalyst does not get consumed in the reaction. It can be used repeatedly for multiple reactions.

A person is driving north in a car at a constant speed. A police officer is driving south toward him at a constant speed. The police officer uses a radar unit to measure the speed of the person’s car. The radar unit sends out waves of a certain frequency toward the person’s car. The waves reflect off the person’s car and travel back to the radar unit in the police car.
What happens to the frequency of the waves detected by the radar unit?
A )The frequency is lower as the person’s car approaches.
B) The frequency is higher as the person’s car approaches.
C) The frequency remains the same but with increased energy as the person’s car approaches.
D) The frequency remains the same but with decreased energy as the person’s car approaches.

For an electron with angular (azimuthal) quantum number ℓ = 2, the magnetic quantum number m can have
Answers
Answer:
-2, -1, 0, +1, +2
Explanation:
The quantum numbers describe the quantum state of an electron in an atom. These numbers are symbolized as n, l, m, and s. There are rules for the combination of these numbers. The angular quantum number (ℓ) is related to the magnetic number (m): if ℓ is equal to a number a, thus m can be any integer number between - a and +a.
According to this rule:
If ℓ = 2, thus m can be have a value of an integer between -2 and +2 ⇒ -2, -1, 0, +1, +2

Two 15.Kg objects are placed at four different distances from each other. At which distance would the two objects have the strongest gravitational attraction to each other?
Answers
Answer:
The strongest gravitational attraction between the two objects will be experienced when the distance between the two objects is smallest.
Explanation:
According to Newton's law of universal gravitation, the force of attraction between two objects is proportional to the products of their masses and inversely proportional to the square of the distance of separation between the two objects. This attraction between objects is known as gravity and it applies to all objects in the universe.
From the law of universal gravitation, since their is an inverse square relationship between gravitational force and the distance of separation between two interacting objects, an increase in the distance of separation will result in weaker gravitational forces. For example, if the distance of separation between two objects is increased by a factor of 2, then the force of gravitational attraction is decreased by a factor of 4 (since 2² = 4). However, if the distance of separation between the two objects is decreased by a factor of two, i.e. is halved, then the force of gravitational attraction is increased by a factor of 4.
Thus, the strongest gravitational attraction between the two objects will be experienced when the distance between the two objects is smallest.
The strongest gravitational attraction happens when the distance between the objects is smaller.
At which distance should we place the objects?We know that the gravitational force between two objects is inversely proportional to the square of the distance between the two objects.
This means that, because the mass of the objects does not change, the only thing that we can change to change the strength of the force is the distance between the objects, and because as we increase the distance the force decreases, we should select the smallest distance between the two objects.
Concluding, the strongest gravitational attraction happens when the distance between the objects is smaller.

Explanation:
Viruses are said to be so numerous that they vastly outnumber the number of stars in the universe. Viruses are quite small and are not technically alive until they get into a living cell.
Viruses are made up of compounds like everything else but just because a virus has not been discovered does not mean that it is made of unknown material. Every natural element available has already been discovered so any new virus is made of compounds of known elements.
How can a compound not conduct electricity as solid but do so when liquid?
HELP
Answers
Explanation:
Ionic compounds conduct electricity when molten (liquid) or in aqueous solution (dissolved in water), because their ionsare free to move from place to place. Ionic compoundscannot conduct electricity when solid, as their ions are held in fixed positions and cannot move.

I say the 1st one I'm so terrible sorry if I'm wrong
Explanation:
Water can take many forms. At low temperatures (below 0°C), it is a solid. When at “normal” temperatures (between 0°C and 100°C), it is a liquid. While at temperatures above 100°C, water is a gas (steam).
The state the water is in depends upon the temperature. Each state (solid, liquid, and gas) has its own unique set of physical properties.
