Review the equation below. 2KClO3 mc012-1.jpg 2KCl + 3O2 How many moles of oxygen are produced when 2 mol of potassium chlorate (KClO3) decompose?

Answers

Answer 1

Answer: Stoichiometry of the reaction:

2 KClO₃   =   2 KCl + 3 O₂
  ↓ ↓

2 mole KClO₃ ----------> 3 mole O₂
2 mole KClO₃ ----------> ?

KClO₃ = 2 * 3 / 2

KClO₃ = 6 / 2

= 3 moles de KClO₃

hope this helps!

Answer 2

Answer:

Answer:

the answer is 3

Explanation:

2 mol of potassium chlorate x $(3)/(2)$ = 3

A change in which property of light will have no effect on whether or not the photoelectric effect occurs??? Frequently energy intensity and wavelength

Answers

Intensity has no affect on whether or not the photoelectric effect occurs. The determining property is frequency and since frequency and wavelength are inversely proportional, wavelength matters as well. If a frequency of light can't cause the photoelectric effect to happen, no matter what the intensity is, the light can't make it happen.

I hope this helps. Let me know in the comments if anything is unclear.

Answer: your answer is intensity

Explanation: your welcome

Matter is anything that has what?

Answers

Matter is anything that has mass and occupies space.

Anything that has physical or real existence is matter. Everything that exists in the known universe manifests itself as matter or energy.
Matter can be liquid, solid or gaseous. Examples of raw: paper, wood, air, water, stone.

Matter is anything that has mass and occupies space.

What is matter?

In science, matter is anything that has mass and occupies space. This means that matter has volume and mass.

Matter is made up of tiny particles called atoms. Atoms are the basic building blocks of matter. They are the smallest units of matter that can exist independently.

The properties of matter are determined by the composition of the atoms that make up the matter. For example, the boiling point of a liquid is determined by the strength of the intermolecular forces between the molecules of the liquid.

When the compound, Na2S, is mixed with water, the Na2S is:soluble because all Na+1 compounds are soluble in water

insoluble because most Na+1 compounds are insoluble in water

soluble because all S−2 compounds are soluble in water

insoluble because there are no water soluble S−2 compounds

Answers

Answer: Option (a) is the correct answer.

Explanation:

Atomic number of sodium is 11 and its electronic distribution is 2, 8, 1. Whereas atomic number of sulfur is 16 and its electronic distribution is 2, 8, 6.

So, when both sodium and sulfur chemically combine together then it results in the formation of an ionic bond due to transfer of an electron from sodium to sulfur atom.

Sodium changes into $Na^(+)$ by losing an electron and sulfur changes into $S^(2-)$ by gain of two electrons from two sodium atoms.

As it is known that water is a polar solvent and all ionic substances will dissolve in water.

Therefore, we can conclude that when the compound, $Na_2S$ , is mixed with water, the $Na_2S$ is soluble because all $Na^(+1)$ compounds are soluble in water.

When the compound, Na2S, is mixed with water, the Na2S is soluble because all Na+1 compounds are soluble in water. The rest of the choices do not answer the question above.
