why do the noble gases have relatively low electron affinities?

Answers

Answer:

Because noble gases have a full octet, their ionization energies are actually quite high. Electron affinity is the amount of energy released when an electron is added to a neutral atom. Because noble gases have stable electron configurations, they have very low electron affinities.

Noble gases have a stable outer shell

Consider the reaction below. H2PO4â€"" H2O Right arrow. H3O HPO42â€"" Which of the following is a baseâ€""conjugate acid pair? H2O and H3O H2O and H2PO4â€"" H2PO4â€"" and HPO42â€"" H2PO4â€"" and H3O.

Answers

Taking into account the Brønsted-Lowry acid-base theory, a base/conjugate acid pair is H₂O/H₃O⁺.

The Brønsted-Lowry acid-base theory (or the Brønsted-Lowry theory) identifies acids and bases based on whether the species accepts or donates protons or H⁺.

According to this theory, acids are proton donors while bases are proton acceptors. That is, an acid is a species that donates an H⁺ proton while a base is a chemical species that accepts an H⁺ proton from the acid.

So, reactions between acids and bases are H⁺ proton transfer reactions, causing the acid to form its conjugate base and the base to form its conjugated acid by exchanging a proton.

In other words, a conjugate base is an ion or molecule resulting from the acid that loses the proton, while a conjugate acid is an ion or molecule resulting from the base that gains the proton:

acid + base ⇄ conjugate base + conjugate acid

In this case, you know:

H₂PO₄ + H₂O → H₃O⁺ + HPO₄⁻

H₂PO₄ behaves like acid because donates an H⁺ proton while H₂O behaves like base because accepts an H⁺ proton from the acid.

So, H₃O⁺ is the conjugate acid of the H₂O and HPO₄⁻ is conjugate base of H₂PO₄.

In summary,  a base/conjugate acid pair is H₂O/H₃O⁺.

Answer:

Alpha decay

Explanation:

Alpha decay can be blocked with only a sheet of paper.

Extra info : -

In general, alpha particles have a very limited ability to penetrate other materials. In other words, these particles of ionizing radiation can be blocked by a sheet of paper, skin, or even a few inches of air.

Hello there!

Alpha decay can be blocked with only a sheet of paper.Gamma rays can only be blocked with something thick and dense.Beta rays can be blocked with something less dense, but thicker than paper.

Jane made this picture to represent a chemical reaction:

Two circles, one white and the other gray are shown on the left. A small portion of the two circles overlap and the label below the circles is XY. An arrow pointing right is shown on the right of the overlapping circles. There are two circles on the right of the arrow, one white and the other gray, and there is a plus sign between them. The white circle is labeled X and the gray circle is labeled Y.

Which of the following statements best explains the type of chemical reaction represented by Jane's picture? (5 points)

It represents a synthesis reaction because one combined reactant forms multiple products.

It represents a synthesis reaction because the same atoms are present in the reactants and products.

It represents a decomposition reaction because one reactant breaks apart and forms two products.

It represents a decomposition reaction because the total mass of the products is less than the mass of the reactant.

Answers

The reaction represents a decomposition reaction because XY is broken into its constituents.

A decomposition reaction is one in which the reactant is broken up into its constituents. In this case, the reactant is XY. The reactant is shown in the left hand side. The reactant is broken up to yield the products. X and Y.

Since the reactant was broken up into the one white and one gray circles labelled X and Y, then the reaction is a decomposition reaction.

Light is very important for photosynthesis and the overall well-being of plants. In a tight space, light and air become limited. This means that plants growing in such a space will not be able to photosynthesize optimally.

what is mass of sodium hydroxide NaOH is present in 0.25 mole of sodium hydroxide
pls be quick​

Answers

Finding molar mass of NaOH

We know that

Molar mass of Sodium (Na) = 23 g/mol

Molar mass of Oxygen (O) = 32 g/mol

Molar mass of Hydrogen (H) = 2 g/mol

So,

Mass of 1 mole of NaOH

=> 1 × 23 + 1 × 16 + 1 × 1

=> 23 + 16 + 1

=> 40 g/mol

Now,

Mass = 40 × 0.25

Mass = 10 g
