Answer:

Hi mate, here is ur answer:

You can dissolve more salt in hot water because in hot water, molecules move faster than cold water because of the higher energy, as a result the molecules of hot water move fast and settles down. As they settle fast, it is easy for higher amount of salt to dissolve in hot water.

HOPE THIS HELPS U

Heat is transferred directly from a heat reservoir at 200 C to another heat reservoir at 5C. If the amount of heat transferred i

Daniel [21]

Answer:

ΔS=0.148 KJ/K

Explanation:

Given that

Q = 100 KJ

T₁=200°C

T₁=200+273 = 437 K

T₂=5°C

T₂=5 + 273 = 278 K

Reservoir 1 is rejecting heat that is why it taken as negative while the reservoir 2 is gaining the heat that is why it is taken as positive.

So the total change in entropy given as

ΔS= - Q/T₁ + Q/T₂

ΔS= - 100/473 + 100/278 KJ/K

ΔS=0.148 KJ/K

Element z reacts with bromine to form an ionic compound zbr2

slamgirl [31]

Explanation:

Physical properties of ZBr₂

The compound is an ionic substance. Therefore it will have properties of ionic compounds. Some of these properties are:

it is a hard solid usually with high melting points or a liquid with high boiling points.
Soluble in water and insoluble in non-polar solvents.
It can conduct electricity in aqueous solutions or in molten form.
it will undergo a fast reaction.

Z is a metal

To form ionic compound, a metal will combine with a non-metal. Bromine is a non-metal and it is expected that Z will be a metal. This is because ionic bonds involves transfer of electron from one specie to the other. Metals are usually the donor and non-metals are the receptor. This is how ionic bond forms. The electrostatic attraction resulting from the ions produced the ionic bond.

Formula of the oxide

Z 0

+2 -2

It is obvious that Z has 2 valence electrons. It will lose the two valence electrons to attain stability.

Oxygen requires 2 electrons to resemble Neon. This combination will give a compound ZO.
