8.1 K is the amount if bonds that nitrogen have
The metal you can insert in aqueous solution of cobalt(ii) nitrate and displace cobalt is zinc.
<h3>Electrochemical series</h3>
Electrochemical series is as know as reactivity series. The electrochemical series list metals in order of decreasing reactivity.
Generally, metals higher up in the series than cobalt metal will displace cobalt(ii) ions from it solution and produce cobalt metal. Therefore, Metals like Zinc will displace cobalt(ii) form it compound.
The reaction with a solution of cobalt (II) nitrate can be represented as follows:
Co(NO₃)₂ + Zn → Zn(NO₃)₂ + Co

Answer:
A molecule of the kind normally found in living systems.
Organic molecules are usually composed of carbon atoms in rings or long chains, to which are attached other atoms of such elements as hydrogen, oxygen, and nitrogen.
Explanation:

Answer: 225 joules.
Explanation:
If this a one dimension problem, this is the motion is in the same direction of the force, the equation for work is:
Work = distance × force
⇒ Work = 15 m × 15 N = 225 joules.
This is a special case of the general equation
Work = |F| |displacement| cosine (angle between the force and displacement)
When force and displacement are in the same direction, the angle is 0, so cos(0) = 1. This is the two vectors are parellel and the work is just the product of the two magnitudes (force and distance)
