1. 90.0 mL of distilled water is added to a 10.0mL sample of 0.150mol/L sodium
aniked [119]

Answer: dilute

Explanation:

A concentrated solution which is used to prepare solutions of lower concentrations by diluting it with addition of water.

A dilute solution is one which contains lower concentration.

Using Molarity equation:

M_1 =concentration of stock solution = 0.150 mol/L

V_1 = volume of stock solution = 10.0 ml

M_2 = concentration of dilute solution = ?

V_2 = volume of dilute solution = (10.0+90.0) ml = 100.0 ml

0.150\times 10.0=M_2\times 100.0

M_2=0.015mol/L

As the concentration is less than the original concentration, the solution is termed as dilute.

As the sun heats the surface of the oceans, two layers of water result. What separates the layers?
Basile [38]

Answer:

Thermocline separate these two layers.

Explanation:

Ocean consist of three major layers on the basis of temperature.

1. Upper layer

2. Deep layer

3. Thermocline

Upper layer:

The first layer is called upper layer which is present on the surface and directly expose to the sun. The sun heat up this upper layer easily and warm it.

Deep layer

The deep layer is present below the thermocline. It is present in deep where sunlight can not approach to it and its temperature remain low.

Thermocline

It is the middle layer, present between the upper and deep layer. It separated the upper layer from deep layer. Its upper portion is warmer while lower is colder.
