The answer of this statement is false because partial charge occurs only on polar bonds.

I should write partial charges on any polar bond within a molecule, but not a molecule which whole is nonpolar because charge only occurs when the atom gains or loses electron.

So we can conclude that The answer of this statement is false because partial charge occurs only on polar bonds.

Explanation:

The process of hydrogenation changes the double bonds in unsaturated fatty acids into single bonds, giving the fat a more solid consistency.

Fat can be defined as one of the main classes of food that is made up of triesters of glycerol and fatty acids or triglycerides.

At room temperature, fats are solids, while those that are liquid at room temperature are called oils.

Fats can be saturated or unsaturated. But an unsaturated fat can be made saturated through the process of hydrogenation.

Hydrogenation of fat can be defined as the addition of hydrogen in the presence of nickel catalyst to form saturated fat.

The Moon is able to fully cover the Sun during a solar eclipse because of its current orbit. One million years from now, this will change because the Moon is slowly moving ____________ from the Earth.

The Moon is able to fully cover the Sun during a solar eclipse because of its current orbit. One million years from now, this will change because the Moon is slowly moving away from the Earth.

[tex]__________[/tex]

Because the Moon passes between Earth and the Sun during a solar eclipse, the Sun is fully hidden. Even though the Moon is much smaller than the Sun, it may entirely obscure the Sun's light from Earth's perspective because it is just the appropriate distance away.

The moon is slowly moving away from earth as  due to the effect of gravity of moon on the earth.

The moon is moving away from the earth due to the effect of it's gravity on earth.Tides which rise in the ocean  cause a drag and thus slow down the spin rate of earth.

This results in loss of angular momentum  which is compensated by the moon speeding up and thus moving away  from the sun. Due  to the moon's gravitational pull  there is production of tidal forces due to which earth's surface bulge out and cause rotation of the earth to loose momentum.Earth's rotation cause this tidal bulge  to occur in  a position which is  slightly ahead of moon in it's orbit around the sun.

As the moon moves away the orbital speed increases and earth's rotation slows down .

During the replacement reaction of magnesium and hydrochloric acid MgCl₂ is produced with hydrogen gas.

Replacement reactions are those reactions in which one entity from the one of the reactant will replace by another entity for the formation of the product.

Balanced chemical reaction between magnesium and HCl will be represented as:

Mg²⁺  +  2HCl  →  MgCl₂  +  H₂

In the baove reaction magnesium displaces hydrogen atom from the acid molecule.

Hence MgCl₂ is produced in the reaction.

C. people rely on ecosystem services provided by intact ecosystems

Explanation:

:) Comment was correct! <3

Protecting and managing biodiversity resources is a crucial part of maintaining ecological harmony and ensuring the survival of species' future generations so that they can live long healthy lives. The correct option is C.

In order to stop the extinction of species, biodiversity should be protected. To keep nature in balance, it is conserved. Other organisms will suffer if one species in the food chain becomes extinct.

The systems that sustain all life on Earth, including humans, depend on biodiversity. We cannot have the healthy ecosystems that we depend on to give us the air we breathe and the food we consume without a diverse variety of animals, plants, and microorganisms.

Thus the correct option is C.

New covalent bonds form between oxygen atoms and hydrogen atoms.

Explanation:

For example, when hydrogen gas, H2(g), is burned in the presence of gaseous oxygen, O2(g), a new substance, liquid water, H2O(l ), forms. The covalent bonds within the H2 molecules and O2 molecules break, and new covalent bonds form between oxygen atoms and hydrogen atoms (Figure 7.1).
