True, because diatomic elements (H2, O2, F2, Br2, I2, N2, Cl2) consist of only one element but are molecules with covalent bonds.
The skin lotion being described above is an example of a colloid specifically an emulsions. Emulsion is a fine dispersion of the minute droplets of one liquid in another in which they are not soluble or miscible. The emulsion is a continuous phase.
Answer:
graph 2
Explanation:
Graham's law:
∴v1: gas diffusion rate 1
∴ v2: gas diffusion rate 2
∴ M1: gas molecular weight 1
∴ M2: gas molecular weight 2
Let Y = R = v1/v2 and X = M2/M1
⇒ Y = √X
the graph for the function Y = √X; is as shown in graph 2.
Answer:
I will not have any of these issues but it must have a very good evening and a great deal to do it in.
