Chemists need the mole concept to bridge the gap between the microscopic world of atoms to the macroscopic world of humans. As you know, the molecular level consists of particles that are invisible to us.

Answer:

it allows us to count atoms and molecules by weighing macroscopic amounts of material.

The part that contains the information that a plant cell uses for growth and activities is known as Chromosome. Thus, the correct option for this question is C.

Chromosomes may be defined as thread-like structures that appear during cell division. These structures are present in the nucleus of the cell and are made up of DNA, RNA, histones, and some non-histone proteins.

Chromosomes were first discovered by E. Strasburger in 1875. But the term chromosome was given by Waldeyer in 1888. Ultimately, the nucleus of the cell contains all sorts of genetic information which are essential for the growth and activities of organisms.

The Nucleus contains DNA which is known as the genetic material of most organisms including plants.

Therefore, a chromosome is a part that contains the information that a plant cell uses for growth and activities. Thus, the correct option for this question is C.

A.In an exothermic reaction, energy is absorbed, bonds are broken, and the temperature decreases.

Answer:Pure water does not contain fluoride, but much drinking water does contain fluoride that is deliberately added to reduce tooth decay of children who drink the water. Some drinking water supplies also contain fluoride naturally.

Explanation:

in small doses not harmful

Fluoride is a chemical that is intentionally added to drinking water in order to prevent tooth decay in children. Pure water does not naturally contain fluoride. Some sources of drinking water naturally contain fluoride as well.

Fluoride is a chemical that is intentionally added to drinking water in order to prevent tooth decay in children. Pure water does not naturally contain fluoride. Some sources of drinking water naturally contain fluoride as well.

Compared to magnesium found in food, magnesium in water is present as hydrated ions, which are more easily absorbed. Thus, the role played by water magnesium in the prevention of magnesium insufficiency may be quite important for people who drink water with high magnesium levels.

Explanation:

Explanation:

The speed at which a planet orbits the Sun changes depending upon how far it is from the Sun. When a planet is closer to the Sun the Sun’s gravitational pull is stronger, so the planet moves faster. When a planet is further away from the sun the Sun’s gravitational pull is weaker, so the planet moves slower in its orbit.

Answer:

10

Explanation:

Atomic number = No. of protons

Therefore, the number of protons of an element with an atomic number of 10, is also 10.

Answer:

Exothermic

Explanation:

Bond strength has everything to do with the energy associated with it. What I mean by that, is a stronger bond will require a lot higher of an energy input to break than a weaker bond.

In the same way, energy is released when a bond is made. So, the formation of a stronger bond releases more energy than the formation of a weaker bond.

So, putting the two ideas together, if the bonds formed as stronger than the bonds broken, then more energy is released than taken in, which means energy is released overall over the course of the reaction. This means that the reaction is exothermic.

If there was energy taken in overall, this would be an endothermic reaction.

Let me know if that makes sense, and hope I helped! :)

Exothermic reaction is a reaction in which the bonds formed during the reaction are stronger than the bonds broken.

When chemical reactions occur, there will always be an accompanying energy change.

In exothermic reaction the bonds formed in the products are stronger than the bonds broken in the reactants whereas in endothermic reaction the bonds broken in the reactants are stronger than the bonds formed in the products.

Answer:

Negatively charged ions are called anions, and an anion is formed when an atom gains an electron. Thus, the atom has an extra charge of electrons,

Explanation:

so it becomes negatively charged.

Negative ions (or anions) are atoms that have gained electrons.

Electrons have a negative charge so if an atom is getting more of them, it's becoming more negative.
