Which of the following best describes a Lewis base? A.It donates protons in solution.

B.It accepts protons in solution.

C.It donates electrons in solution.

D.It accepts electrons in solution.

Answers

Answer 1
Answer:

Answer: Option (C) is the correct answer.

Explanation:

According to Lewis, a base is a substance or specie which is able to donate electrons.

For example, is a lewis base because nitrogen has a lone pair of electron.

Therefore, when ammonia is dissolved in HCl it will accept the hydrogen atom as nitrogen gave electron to the hydrogen atom. As a result, hydrogen bonds with nitrogen atom.

               

Thus, we can conclude that it donates electrons in solution best describes a Lewis base.

Answer 2
Answer: Not 100% sure but I believe it is C.

Which substances dissolves in pure water and produces a solution that is a good conductor of electricity? 1) CaCl2
2) C6H12O6
3) N2
4) O2

Answers

Answer:

Explanation:

We have to keep in mind that a good conductor would be a substance that has the ability to produce ions (charged species). These species are responsible for the electricity conduction on water.

Therefore, we have to check which ones of these compounds will produce ions in water. For and we have diatomic molecules (also gases) this type of molecules don't have the ability to produce ions due to his simplicity, they already are very stable.

In the sugar molecule we have a covalent compound. The ions are produced by ionic compounds. So, this molecule can be discarded too.

For we have an ionic compound that have the ability to produce ions:

~~Ca^+^2~+~2Cl^-" alt="CaCl_2~~->~~Ca^+^2~+~2Cl^-" align="absmiddle" class="latex-formula">

So, this is the compound that would be a good conductor due to the and the ions.

CaCl2 is a good conductor of electricity when dissolved in water.

Write the equilibrium constant expression for this reaction: h2so4 (aq) → 2h+ (aq) + so−24 (aq)

Answers


when Kc = [the concentration of products]^(no.of its mol in the balanced equation)     /  [the concentration of the reactants]^(no.of mol in the balanced equation)
∴ The equilibrium constant expression for this reaction is:
Kc= [H+]^2 * [So4-2] / [H2SO4]

Answer:

Explanation:

The equilibrium constant K is a parameter that relates the concentration of products to that of the reactants at equilibrium and under a given temperature.

Consider a hypothetical reaction:

xA + yB ↔ zC

where A and B are the reactants ;  C is the product

x and y are the coefficients of the reactants; z is the product coefficient

The equilibrium constant is given as:

A binding protein binds to a ligand l with a kd of 400 nm what is the concentration of ligand when y is 0.25

Answers

Answer:

The answer is 7600 nm.

Explanation:

As, Y = 0.25 = [ L ÷ (400 + (L)]

0.95 x 400 + 0.25 [ L] = [ L ]

380.25  = [ L ] - 0.95 [ L ]

              = 0.05 [L]

[L] = 380 ÷ 0.05 = 7600nm

Determine what type of decay occurs when thorium-231 undergoes radioactive decay to form protactinium-231.

Answers

Thorium and Protactinium are elements in the periodic table with atomic number which corresponds to the number of proton in the nucleus equal to 90 and 91, respectively. 

From the radioactive decay of Thorium-231 to Protactinium-231, the atomic number is increased by 1 while the mass number is unchanged. This type of radioactive decay is called the BETA DECAY.
