We will have to have
first in mind the formula of
density:
ρ
, where
ρ is the density,
m is the mass and
V is the volume.
We will next calculate the mass of the diamond:
1 carat ............................................... 200 mg
1.1 carat ............................................ x mg.
We will next find out the volume:
ρ
=> V =
=
Answer: False
Explanation: adding heat to matter results in thermal energy.
The net ionic equation is as below
H^+(aq) + H^-(aq) → H2O(l)
Explanation
from the chemical equation
HClO4(aq) + NaOH (aq) → H2O(l) + NaClO4(aq)
write ionic equation
that is,
H^+(aq)+ClO4^-(aq) + Na^+(aq) +OH^-(aq)→ H2O(l) + Na^+(aq)+ClO4^-(aq)
cancel the spectator ions in both side(ions that do no take place in a chemical equation)
that ClO4^- and Na^+
the net ionic is therefore
= H^+(aq) + OH^-(aq) → H2O(l)
Its A It provides support for the body
The bones(Cartilage?) provide support for the body
Agitate (stir) the solution
Heat the solution
Shake the solution
Explanation:
To increase the solubility rate, we can:
- Agitate the solution by stirring it. This will bring more of the solute in contact with the solvent. The process of stirring enables contact between solute faces and the dissolving medium.
- Heating the solution also helps. Increase in temperature by heating a solution generally cause a rise in reaction rate. This allows for more frequent collisions between the particles of the specie.
- Shaking the solution brings solute and solvent into more contact.
