Which organic compound is unsaturated?(1) 2-methylbutane (3) 2-hexanol
(2) 2-chloropropane (4) 2-pentene

Answers

The answer is (4) 2-pentene. The pentene belongs to olefin and has double bonds between the carbon atoms. And the other three belongs to alkane which don't have double bonds. So the pentene is unsaturated.

Answer:

Yes; new substances formed, as evidenced by the color changes and bubbles. Some signs of a chemical change are a change in color and the formation of bubbles. The five conditions of chemical change: color chage, formation of a precipitate, formation of a gas, odor change, temperature change

Which equations shows the complete dissociation of a strong base? HCl -> cl- + H+

HNO2 -> H+ + NO2-

HA + h20 -> A- + H+ + h20

BOH + h20 -> B+ + OH- + H20

Answers

The correct answer is the fourth option. The complete dissociation of a strong base is BOH + h20 -> B+ + OH- + H20 since this is the only base from the choices given. A base is a substance that accepts hydrogen ions.

Answer : The correct option is, (4) $BOH+H_20\rightarrow B^++OH^-+H_20$

Explanation :

Strong acid : Strong acids are those acids which are completely dissociates into ions in water. It dissociates into hydrogen ion and an anion.

Strong base : Strong base are those base which are completely dissociates into ions in water. It dissociates into hydroxide ion and a cation.

In all the given options, option (4) $BOH+H_20\rightarrow B^++OH^-+H_20$ equation shows the complete dissociation of a strong base.

While the other options shows the complete dissociation of an acid.

952 grams of ammonium carbonate are dissolved to make 1750 mL of solution

Answers

(%m/v) =mass of solute (in g) / volume of solution (in mL) x 100

= 952 g (NH4)2CO3 / 1750 mL x 100

= 0.544 x 100

(%m/v) = 54.4 g /mL or 54.4% concentration of ammonium carbonate

What is the mass of 2.90 ×1022 molecules of NaOH (Molar mass = 40.0 g/mol)?

Answers

40.0 g ( 1 mole ) --------------- 6.02x10²³ molecules
? ? --------------------------- 2.90x10²² molecules

mass = 2.90x10²² * 40.0 / 6.02x10²³

mass = 1.16x10²⁴ / 6.02x10²³

mass = 1.9269 g

hope this helps!
