How much NH4Cl will dissolve in 100 g of water at 85 °C?

The solubility is 70 g/100 g water.

Explanation: It appears that "they" are asking you to interpret a solubility curve like the one below.

You draw a vertical line from 90 °C on the horizontal axis upward until it hits the curve for

NH

4

Cl

.

Then, go horizontally from there until you reach the vertical axis.

The solubility is 70 g/100 g water.Solubility curve

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
