Substances that are not chemically bonded are mixtures.
Inertia. Inertia is the natural tendency of bodies to remain in their states of either rectilinear or resting motion.
<span>The purpose of washing the product with NaOH is simply to
neutralize any acid which remained or leaked after the 1st initial
separation. The NaOH base reacts with the acid to form neutralization reaction products
which are soluble in water.</span>
Answer:
subtract
Explanation:
To find the net force of two bodies going in opposite directions, we must subtract the forces this is because they are not additive forces.
- The net force is the resultant force acting on a body.
- This resultant force is the single force that will produce the same effects as all given forces.
- When forces are directed oppositely on a body, they are subtracted from each other to find the net force.
Answer:
the ionic radius of the anion 
Explanation:
From the diagram shown below :
The anion 
is located at the corners
The cation 
is located at the body center
The Body diagonal length = 
∴ 
Given that :
(i.e the ratio of the ionic radius of the cation to the ionic radius of
the anion )
Also ; a = 664 pm
Then :
Therefore, the ionic radius of the anion
