The possibility of metals replacing each other is dependent on the relative positions of the metals in the activity series.

The activity series is an arrangement of elements in order of decreasing reactivity. The elements that are higher in the series can displace the elements that are lower in the series.

Before we make a decision in each case, we must consider what metal is lower or higher in the series;

  • Between Na and K, Na is lower in the series so the answer is no
  • Between Co and Cu, Co is higher than Cu in the series so the answer is yes
  • Since Zn and Zn^2+ are just a specie and its ion, the answer is no.
  • Since Ba is higher than Ni, Ni can not replace Ba so the answer is no

How many mg of metallic ions are in 1.0 mL of 0.10 M LINO3
Anton [14]

Answer:

0.6941 mg

Explanation:

First we <u>calculate how many LiNO₃ moles there are</u>, using the <em>given concentration and volume</em>:

  • 1.0 mL * 0.10 M = 0.10 mmol LiNO₃

As 1 mol of LiNO₃ contains 1 mol of Li,<em> in the problem solution there are 0.10 mmol of Li</em> (the only metallic ion present).

Now we<u> convert Li milimoles into miligrams</u>, using its <em>atomic mass</em>:

  • 0.10 mmol Li * 6.941 mg/mmol = 0.6941 mg

Name the functional group in the<br> following molecule:
Anna71 [15]

Answer:

B. Aromatic

Explanation:

Functional groups are groups that differentiate a specific organic compound from others. A functional group determines the chemical property of the compound that possesses it.

For example, just like alkene and alcohol functional groups have characteristics double bond (=) and hydroxyl (OH) group respectively, the image in the attachment of this question has a BENZENE RING at the core of its structure, hence, the organic compound can be regarded to have an AROMATIC FUNCTIONAL GROUP.
