In a pack of CaCl2 and H2O, hydrolysis of Ca+2 will occur

This will result in formation of Ca(OH)2.

The reaction is exothermic in nature

so the balanced thermo-chemical equation will be

CaCl2(aq) + H2O (l) ---> Ca(OH)2 + 2HCl + Heat

In a pack of NH4NO3 and H2O hydrolysis of NH4+ will occur as

NH4NO3 (aq) + H2O(l) + Heat ---> NH4OH(aq) + HNO3 (aq)

It is an endothermic reaction

Devise a way to separate sand from a mixture of charcoal, sand, sugar, and water

madreJ [45]

A mixture of charcoal, sand, sugar, and water is a heterogeneous mixture. Sugar can easily dissolve in water. Slightly heating the mixture will ensure all of the sugar is dissolved in the water. The mixture then can be filtered to separate out sugar solution from sand and charcoal. The mixture of sand and charcoal is washed several times with water and filtered so that no traces of sugar solution remain in the mixture. To the mixture containing sand and charcoal, water is added. Charcoal being lighter floats on the surface of water, whereas sand being heavy sinks to the bottom. The charcoal floating can be removed manually. After all the charcoal is removed, the mixture of sand and water is again filtered and the sand collected on filter paper is dried. Therefore, by using the above process sand can be separated out from a mixture of charcoal, sand, sugar, and water.

Before Mendeleev published his periodic table, Döbereiner grouped elements with similar properties into "triads," in which the u

mamaluj [8]

Answer:

a) The atomic mass of the potassium is 54.23 amu.

b) The melting point of bromine gas is 6.3°C.

Explanation:

a) Atomic mass of Na =22.99 amu

Atomic mass of Rb = 85.47 amu

Döbereiner triad = Na , K ,Rb

Taking average of atomic masses of Na and Rb

Atomic mass of the K = $\frac{22.99 amu+85.47 amu}{2}=54.23 amu$

The atomic mass of the potassium is 54.23 amu.

b) Melting point of chlorine gas =-101.0°C

Melting point of iodine gas =113.6°C

Döbereiner triad = Cl, Br , I

Melting point of bromine gas :

= $\frac{-101.0^oC +113.6^oC}{2}=6.3^oC$

The melting point of chlorine gas is 6.3°C.
