Answer: By performing the flame test

Explanation:

The flame test can be performed by the teacher to visually identify the substance in the solution. The metals give a characteristic color on burning. The heat of the flame causes the excitation of the electrons present in the metal ions this leads to release of energy along with the emission of visible wavelength of light. This visible light can be observed by human eye. For example, the copper produces the blue color in flame, barium gives green flame, and sodium gives yellow flame.

Explanation:

that how it's are related are in the periodic table .

Answer:

Explanation:

The electronic configuration of an element is related to its position on the periodic table.

The links are:

the number of circles in the electronic configuration of an element is represented in the periodic table as the period number that element is situated in

the number of electrons in the outermost shell of an element is represented in the periodic table as the group number that element is situated in

the number of electrons in all shells of an element is represented in the periodic table as the element's atomic numbe

The initial temperature of the metal = 35 °C

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]

The bouncing back of light waves observed when light waves hit ice and most of them bounce off and radiate back into space is called reflection.

Light waves are a form of waves which produces visible sensitization of the eyes

Light waves have properties of waves such as:

When light waves hit ice, most of them bounce off and radiate back into space.

This property of light waves is known as reflection.

When light waves hit ice, most of them bounce off and radiate back into space, hence, ice is best described as a reflective surface.

A reflective surface is one which can cause incident light to bounce back (reflection).

According to this question, when light waves hit ice, most of them bounce off and radiate back into space. This means that most of the incident light reflects off the ice surface.

Therefore, the ice surface is best described as a reflective surface.

Answer:

2.Diffusion

Explanation:

As we metabolize certain nutrients for the correct functioning of our cells, carbon dioxide is produced as a result. We need oxygen in order to metabolize them, so we need to have a system to incorporate it, and to eliminate the carbon dioxide produced.

This system is provided by the interaction between the respiratory system, which allows the enter of oxygen into the body and gets rid of the carbon dioxide, and the circulatory system, which acts transporting carbon dioxide and oxygen to and from the lungs, respectively.

The surface available for the gaseous exchange is enlarged by the pulmonary alveoli. The alveoli are the terminal aerial spaces of the respiratory system and the structures where the exchange between the air and blood is produced. Each alveolus is surrounded by a net of capillaries, where oxygen is freed from the hemoglobin and moves into the cells by diffusion. Carbon dioxide, diffuses out of the cells into the capillaries, where most of it dissolves in the plasma of the blood.

Answer:

D.A chemical that is not from living things

Answer:

A gas with a rotten egg smell is evolved

Explanation:

When iron fillings and sulphur were heated in the vessel, the following chemical reaction took place;

Fe(s) + S(s) -----> FeS(s)

This is a direct combination reaction.

Subsequently, when dilute H2SO4 is added, the following reaction takes place;

FeS(s) + H2SO4(aq) ------> FeSO4(aq) + H2S(g)

He immediately observes the evolution of a gas with a rotten egg smell.

The question is asking you to compare each elements electrons, specifically valence since it mentioned their placement on the table.

Similarly: they both are only one electron away from stability (a full octet)

Difference: Sodium will want to loose the one electron, and Chlorine will take it.

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

Now the equation is balanced.

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

The area of the widest part of the figure is 144cm²

Explanation:

Some assume our planet's changing distance from the sun causes the change in the seasons. That's logical, but not the case for Earth. Instead, Earth has seasons because our planet's axis of rotation is tilted at an angle of 23.5 degrees relative to our orbital plane, that is, the plane of Earth's orbit around the sun

Josh is washing glasses with soap and water. He is afraid to carry the glasses because they are slippery. Josh could dry them with a towel to keep the glasses from being slippery.

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.

Thus,  Josh could dry them with a towel to keep the glasses from being slippery.
