Why does the salt reappear when the water evaporates??

Answers

Answer 1

Answer:

Salt particles move about the water. Each particle is surrounded by water molecules.The water particles (molecules) keep the salt particles from rearranging themselves back into a salt crystal. Salt particles are carried throughout the solution surrounded by water particles.

As the water evaporates less and less water molecules are present to keep the salt particles apart. The salt therefore recrystalises and can be collected.

Answers

Answer:

144cm²

Explanation:

Given dimensions:

     Length x breadth x thickness

        18cm  x   8cm    x    5cm

The widest part of this figure will be the face containing the length and the breadth.

The breadth is the width of the figure;

Area of the widest part  = length x breadth = 18cm x 8cm  = 144cm

When Earth is tilted on its axis why does it orbit the sun ?

A 20.0g sample of metal with a specific heat of 5 J/(g°C) raised it's initial temperature to 40.0 when 500J heat was added. What was the initial temperature of the metal?

Answers

The initial temperature of the metal = 35 °C

Further explanation

Heat can be formulated :

Q = m . c . ΔT

Q = heat, J

c = specific heat, J/g C

ΔT = temperature, °C

m = 20 g

c = 5 J/(g°C)

Q = 500 J

T₁ = 40 C

the initial temperature :

[tex]\tt \Delta t(T_2-T_1)=\dfrac{Q}{m.c}\\\\40-T_1=\dfrac{500}{20.5}\\\\40-T_1=5\\\\T_1=35^oC[/tex]

5 20 oC good poor

Answers

Answer:

1.  c

2. ionic

3. c

4. ionic

5. alloy or ionic

Explanation:

The compound classification.

The compounds are classified as per several different criteria and one common elements is the specific element that is present this makes it an iconic or a molecular. The presence of the oxides, hydrides, and various atomic groups.

Hence the answer is melting point to conductivity classified as c, iconic, c, iconic, and alloy.

A poor conductor of electricity will have a conductivity classification of c. The 396 good conductors will be iconic and a 0 C not teste will have a conductivity of c. The 200 C of good conductor will be iconic and 20 C of good conductor will be alloy or iconic.

What are glasses ?

Glasses are visual eyewear that have lenses fixed in a frame that holds them in front of a person's eyes. The frame often has a bridge over the nose and arms that rest over the ears. Glasses are also known as eyeglasses or spectacles.

The term "glasses" likely originated from the word "spyglass," which was originally used to describe "a pair of eyeglasses" that had to be held up to the eyes in order to be fully effective.

Eyeglasses, often known as glasses or spectacles, are lenses that are mounted in frames and worn in front of the eyes to improve vision or to correct astigmatism, myopia, or hyperopia.

Write a balanced equation for the following reaction;
potassium metal reacts with nitrogen gas to form potassium nitride

Answers

Answer:

6K + N₂ —> 2K₃N

Explanation:

K + N₂ —> K₃N

The above equation can be balanced as illustrated below:

K + N₂ —> K₃N

There are 2 atoms of N on the left side and 1 atom on the right side. It can be balance by putting 2 in front of K₃N as shown below:

K + N₂ —> 2K₃N

There are 6 atoms of K on the right side and 1 atom on the left side. It can be balance by putting 6 in front of K as shown below:

6K + N₂ —> 2K₃N
