which is the correct order of ease of carbon dioxide production by heating the group II metal carbonates?

seraphim [82]

Which is the correct order of ease of carbon dioxide production by heating the group II metal carbonates?

A) $BaCO_{3} > SrCO_{3} > CaCO_{3} > MgCO_{3}$

B) $MgCO_{3} > CaCO_{3} > SrCO_{3} > BaCO_{3}$

C) $CaCO_{3} > MgCO_{3} > BaCO_{3} > SrCO_{3}$

D) $SrCO_{3} > BaCO_{3} > CaCO_{3} > MgCO_{3}$

Answer:

Explanation:

The correct option is A:

$BaCO_{3} > SrCO_{3} > CaCO_{3} > MgCO_{3}$

On the periodic table, carbonates required stronger heating as one does down the groupings in order for them to decompose. The implication is that the stability of compounds will increase from $MgCO_{3}$ to $BaCO_{3}$ .

So the carbonates will be stable according to the following order:

$BaCO_{3} > SrCO_{3} > CaCO_{3} > MgCO_{3}$ , thus making B the correct answer.

1. When light is reflected, the incident rays are bent and change direction.

ololo11 [35]

1. B. False, when light is reflected, the incident rays are bent and change direction.

2. B. become diffused. Light hitting a rough surface would most likely.

3. B. False. Plane mirrors create virtual images.

4. D. All of the choices are correct.

5. B. The illusion of water on top of hot asphalt on a summer day is mirage.

6. A. The mirror refracts light rays that pass through it outward and away from the optical axis is convex mirrors.

7. A. True. The bending ability of a substance is recorded on the index of refraction.

8. A. True. Light travels at the same speed at all times.

<h3>What is refraction of light?</h3>

The refraction of light is change in speed and direction of light when it hits obstacle.

<h3>What is reflection is light?</h3>

Reflection of Light occurs when the waves encounter a surface or other boundary that does not absorb the energy of the radiation and bounces the waves away from the surface.

<h3>Reflection of light can be diffused or Specular</h3>

Specular reflection is a type of surface reflectance often described as a mirror-like reflection of light from the surface.

Diffuse reflection is the reflection of light or other waves or particles from a surface such that a ray incident on the surface is scattered at many angles rather than at just one angle.
