Answer:
CaF2
Explanation:
Because HF is a weak acid, fluoride salts behave as bases in aqueous solution. As a Lewis base, F– accepts a proton from hydronium, which is transformed into a water. Picture is attached.
The kinetic theory of gases describes a gas as a large number of submicroscopic particles, all of which are in constant, rapid, random motion. The randomness arises from the particles' many collisions with each other and with the walls of the container.
Answer:
<h2>Density = 8.96 g/cm³</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass of copper = 89.6 g
volume = 10 cm³
Substitute the values into the above formula and solve
That's
We have the final answer as
<h3>Density = 8.96 g/cm³</h3>
