When a saturated solution of NH4Br dissolved in 100 grams of water is cooled from 60°C to 30°C, how much NH4Br will precipitate?
stepladder [879]

Answer:

m_{precipitated}=24.8g

Explanation:

Hello,

In this case, since at 60 °C, 108 grams of ammonium bromide are completely dissolved in 100 grams of water for a saturated solution, once it is cooled to 30 °C, wherein only 83.2 grams are completely dissolved in 100 grams of water, the following mass will precipitate:

m_{precipitated}=108g-83.2g\\\\m_{precipitated}=24.8g

Best regards.

Which of the following elements has 3 electrons in the outermost d orbital?
Nina [5.8K]

Answer:

A

Explanation:

Element A has 3 electrons in outermost shell so its valency is 3. It will loose 3 electrons to attain stability, as loss of 3 electrons is easier than gain of 5 electrons.

Valency of B is −2 as it will gain 2 electrons to attain stability and combine with other atom.

Valency of A⟶+3

Valency of B⟶−2

(Refer to Image)

Cross multiply valency of A and B

∴A2B3 compound will be formed.
