A base has Kb of 2.5 x 10-11. which of the following statements is true?(1 point)a) this is a concentrated base
b)this base ionizes slightly in a aqueous solution
c)this is a strong base
d)an aqueous solution of this base would be acidic
I'm thinking b. help and i'll give medal. Thank you

Answer 1

Answer: I disagree with the answer pick of D. If you have a neutral pH 7 solution and you proceed to add a base even with an relatively insignificantly low Kb your solution would still be more basic then acidic. The answer should be b which is true that the base only ionizes slightly in aqueous solution. This is also truer to the definition of what Kb represents.

How many grams of copper, CU are there in 2.55mol of CU?

Answers

2.55 mol Cu* 63.54 g Cu / 1 mol Cu so you cancel mol Cu, leaving you with 2.55 * 63.54 g Cu /1 =162.027

Final answer:

To calculate the number of grams of copper (Cu) in 2.55 mol of Cu, multiply the number of moles by the molar mass of copper. The molar mass of Cu is 63.55 g/mol. Therefore, there are 162.05 grams of copper (Cu) in 2.55 mol of Cu.

Explanation:

To calculate the number of grams of copper (Cu) in 2.55 mol of Cu, we need to use the molar mass of copper. The molar mass of Cu is 63.55 g/mol. Therefore, 2.55 mol of Cu is equal to:

2.55 mol Cu × 63.55 g/mol = 162.05 g Cu

So, there are 162.05 grams of copper (Cu) in 2.55 mol of Cu.

Which element is least likely to undergo a chemical reactionA) lithium
B) carbon
C) flourine
D) neon
and can you give me a explanation with the answer you chose

Answers

The correct option is D.
Elements undergo chemical reactions because they are not stable and they want to become stable, that is they want to attain octet form. To attain octet form, an atom of element must have eight electrons in its outermost shell. Thus, elements undergo various types of chemical bonding in order to have 8 electrons in their outermost shells.
Neon has atomic number of 10 and its electronic configuration is 2,8. This means that, neon already has 8 electrons in its outermost shell and so does not need to form any chemical bond with any other element again, it is already stable. This is why, neon is the least likely to undergo chemical reaction and this is also the reason whey the element is chemically inert.
The other elements given in the option do not have 8 electrons in their outermost shell, so they will be quite willing to undergo chemical reactions in order to become stable.

d neon is the element that is least likely to undergo a chemical reaction

Which of the following compounds contains both ionic and covalent bonds?Select one:
a. NH3
b. NaNO3
c. CH3OH
d. AlCl3

Answers

Answer:

d. AlCl3

Explanation:

In AlCl₃ each Al³⁺ cation is surrounded by three Cl⁻ anion. Al³⁺ has a small ionic radius giving it a high charge density whereas Cl⁻ has a large ionic radius, low charge, and easily polarizable. Al³⁺ pulls one electron from each of the three Cl⁻ ion thus giving the Al-Cl bond a covalent character.

NaNO3 because Na is a cation allowing it to bond with anions which are NO3. NO3 is a covalent compound because nitrogen and oxygen are sharing electrons when they bond; thus making a covalent bond
