Drag one molecule and one chemical property to each bin. If one property can apply to more than one functional group, choose the
BartSMP [9]

There are different kinds of functional group. The answer to the functional group, is below.

  • (OH) Alcohol is one of the most polar and may act as a weak acid
  • (COOH) Carboxylic acid serves as the acid.
  • (C=O) Aldehyde: can be an isomer of a chemical ketone
  • (S-H) Thiol usually transform to a disulfide bond
  • (NH2) Amine serves to be the base of chemical compounds
  • (PO4) Organic phosphate carries a negatively charged atom.

<h3>What is functional group ?</h3>

A functional group in organic chemistry is known to be a composition of atoms that is found inside a molecules that often bind together to react in certain ways.

The Examples of functional groups are the group hydroxyl, ketone, amine, and others.

Ariana is accelerating her car at a rate of 4. 6 m/s2 for 10 seconds. Her starting velocity was 0 m/s. What was her final veloci
Studentka2010 [4]

Answer:

<h3>the answer is v=46 m/s</h3>

Explanation:

<h3>to find the final velocity we use formula from uniformly accelerated motion , equation 1, that is ; V=U+at</h3>

<h3>our given is U=0m/s</h3><h2> a=4.6m/s^2</h2><h3> t=10s</h3><h3>requaired,V=?</h3>

<h3>solution will be; V = u+at</h3>

<h3>replacing the values of each individual</h3>

<h3>V=0m/s+(4.6m/s^2)(10s)</h3><h3>V=0m/s+46m/s ;second found on the unit of acceleration canceled by the unit of time and finaly the left is m/s</h3><h3>V=46m/s</h3>

2) Use the Kspa expressions for CuS and ZnS to calculate the pH where you might be able to precipitate as much Cu2 as possible w
Phantasy [73]

The pH where you might be able to precipitate as much Cu2 as possible will be any value that is less than 5.85.

<h3>How to illustrate the information?</h3>

The solubility product of salt is defined as the product of molar concentrations of ions in a saturated solution of it.

An ion will be precipitated if the ionic product exceeds the solubility product of the cation. In the case of Cu and Zn, the solubility product is greater for Zinc than Copper.

Also Cu will be precipitated in an acidic medium while Zn is precipitated in an alkaline medium. We have for CuS, K= S2 so S = 2.4495*10-8. For ZnS, S = 0.1414. So the lower the pH higher will be the amount of CuS precipitated.

If we are starting with 0.075M CuS and ZnS solution it will have 0.075 moles each of Cu2+, Zn2+, and S2. Since the anion concentration can be equated to POH, POH for Cus and Zns are 14.096 and 5.85.

The maximum precipitation will take place is any value which is less than 5.85.
