The answer is head-to-tail joining of monomers. Monomer used in condensation have  two functional groups that combine to form amide and ester linkages. When this reaction occurs, water molecules is removed and that is why it is called a condensation reaction.

Which statement describes the water gas particles in the air above the cup compared with the water liquid
Law Incorporation [45]

Answer:

The particles move faster and are far apart

Explanation:

A substance may exist in three states of matter; solid, liquid and gas.

In the solid state, there is very strong intermolecular forces between the particles of the substance. They can only vibrate or rotate about their mean positions but can not translate.

In the liquid state, the particles of the substance have a greater degree of freedom than in the solid. The magnitude of intermolecular forces is lower than in solids, the molecules can move at low speeds.

In a gas, the molecules are separated from each other with negligible intermolecular interaction hence they move at very high speed.

Therefore, for the water gas particles in the air above the cup; the particles move faster and are far apart.

what is the concentration of hydroxide ions after 50.0 ml of 0.250 m naoh is added to 120 ml of 0.200 m na2so4? please show all
Galina-37 [17]

The concentration of the hydroxide ions after 50 ml of 0.250M NaOH is added to 120ml of 0.200M Na2SO4 is 7.35 x 10^-2 M.

What is meant by concentration?

Concentration is the total amount of solute present in the given volume of solution. this is expressed in terms of molarity, molality, mole fraction, normality etc. The term concentration mostly refers to the solvents and solutes present in the solution.

Concentration of hydroxide ions can be calculated by,

M (OH^-) = V (NaOH) x M (NaOH) / V (total) = 50ml x 0.250M / 50ml + 120ml = 0.0735M = 7.35 x 10^-2 M.

where M (OH^-) = concentration of hydroxide ions, V(NaOH) = volume of NaOH, M(NaOH) = concentration of NaOH.

Therefore, the concentration of the hydroxide ions after 50 ml of 0.250M NaOH is added to 120ml of 0.200M Na2SO4 is 7.35 x 10^-2 M.

Which of the following would form an anion? He H N B
vagabundo [1.1K]
<h3><u>Answer;</u></h3>

Nitrogen (N)

<h3><u>Explanation;</u></h3>
  • Atoms may lose or gain electrons to achieve stability. Metal atoms lose electrons to attain stable configuration, and as a result they form positively charged ions called cations.
  • <u>Non-metals on the other hand gain electrons to attain stable configuration, and as a result form negatively charged ions called anions.</u>
  • <u>Among the elements given above nitrogen (N) gains electrons to form a negatively charged ion called anion. </u>
