Answer:
C. Solid in liquid
Explanation:
Seawater is an example of a solid in liquid solution.
Sea water is made up of:
- water
- mineral salts
- dissolved gases
A liquid solution is always made up of a solute being dispersed within the solvent medium.
The solvent is the liquid or fluid medium.
Such solutions are homogeneous because the solute particles are distributed evenly or uniformly in the solvent.
The solute is usually present in smaller amount compared to the solvent.
Gold is classified as a Solid
Answer:
Q_d=35881 J/mol
So the activation energy is 35881 J/mol.
Explanation:
Consider the following equations:


Solving the above two equation to find the Q_d in term of diffusivity and temperature we will get:

where:
Q_d is the activation energy
D_1 is the diffusivity at T_1
D_2 is the diffusivity at T_2

Q_d=35881 J/mol
So the activation energy is 35881 J/mol.
Answer:
shows geometrical isomerism.
Explanation:
<u>Geometrical isomerism:</u>
<em>"Molecules having same molecular formula but the but difference in the arrangement of atoms."</em>
Cis and trans isomers are called geometrical isomers.
Among the given ,
shows geometrical isomerism.
The <em>cis </em>and <em>trans</em> forms of the
are as follows.
