Answer:

Increasing the temperature increases reaction rates because of the disproportionately large increase in the number of high energy collisions. It is only these collisions (possessing at least the activation energy for the reaction) which result in a reaction.

Explain the difference between elements and compounds, a teacher filled

stiv31 [10]

Answer:

Kindly check explanation.

Explanation:

So, without mincing words the solution to this particular Question is given below:

First, an ELEMENT is a that entity that has what is known as the atoms. Although, there might be more elements but the recognized elements are group into the periodic table/chart. Examples of elements are Hydrogen, Helium, Lithium, Beryllium, Boron, carbon, Nitrogen, oxygen, Fluorine, neon, sodium, magnesium, Aluminium and so on.

A COMPOUND consist of different elements that are chemically combined. Examples of compounds are; H2O, CaCO3, H2SO4, HNO3, MgCl2, NaCl, HCl and many more.

Also, elements has the same atoms while componds have different number of atoms since it is a combination of elements.

Finally, ELEMENTS can not be broken down through the use of chemical process while COMPONDS can be broken down through chemical processes.

To the second part of the question. The box that will represent elements will contain balls of the same colors and the balls are not joined together.

Which cellular change in an organism could be inherited be the next generation?

ikadub [295]

In order for a cellular change to be inherited, this change must be present in the male gamete, or sperm or present in the female gamete, the egg or ovum. This is due to the fact that a baby is created from the fusion of an egg and sperm. Therefore, choice 2, the deletion of a single DNA base in a sperm cell of a trout, is the correct answer.

If we think about it logically, cellular changes in other parts of body should not affect the next generation. For example, if mom has skin cancer, it does not mean at all that the baby will have it as well.

The product of a Lewis acid-base reaction is a(n) __________, a single species that contains a new covalent bond. The Lewis acid

andreyandreev [35.5K]

Answer:

Adduct, donate, accept

Explanation:

Lewis acids are those having suitable vacant orbital for electron acceptance and forming a covalent bond with an electron rich species. Example: $BCl_{3}$ (B has vacant 2p orbital for electron acceptance)

Lewis bases are those having energetically available unshared electrons that can be donated to an electron deficient species and form a covalent bond. Example: $NH_{3}$ (N has energetically available lone pair)

So, product of Lewis acid-base reaction is an adduct ( $BCl_{3}-NH_{3}$ ) where a new covalent bond is formed between B and N.
