Answer:

natural resources: materials or substances such as minerals, forests, water, and fertile land that occur in nature and can be used for economic gain.

renewable resources: a natural resource that is unlimited or that is naturally replenished rather quickly, such as sunlight or water

non renewable resources: (also called a finite resource) is a natural resource that cannot be readily replaced by natural means at a pace quick enough to keep up with consumption.

Match each molecular formula to the corresponding empirical formula.

lawyer [7]

Explanation:

C₄H₈O₂ C₂H₄O

C₄H₁₂O₄ CH₃O

C₂H₁₀O₂ CH₅O

The empirical formula is that which expresses the composition of a compound in the simplest whole number ratio of the atoms of the different elements that makes up a compound.

The molecular formula is the true formula of the compound. It expresses the actual number of moles of atoms of the different elements present in a molecule of the compound.

C₄H₈O₂ C₂H₄O

4: 8 : 2 divided by 2 gives 2: 4 : 1

C₄H₁₂O₄ CH₃O

4: 12: 4 divided by 3 gives 1: 3: 1

C₂H₁₀O₂ CH₅O

2: 10: 2 divided by 2 gives 1: 5: 1

Mama L [17]

Explanation:

Nitrous oxide or dinitrogen monoxide can be simple be prepared by the decomposition of ammonium nitrate in the following way -

The reaction is as follows -

NH₄NO₃ ----------------> N₂O + H₂O

This is the unbalanced reaction as was asked in the question , without mentioning the states of matter .

The reaction is carried out in an anhydrous condition ,since , ammonium nitrate can explode on heating .

What is Avogadro's constant?
Avogadro's number tells us how many particles are in one mole (or mol) of a substance. Electrons, molecules, or atoms could be among these particles. Avogadro's number has a value of approximately 6.022140857×10²³ mol⁻¹. Avogadro's number tells us how many particles are in one mole (or mol) of a substance. Electrons, molecules, or atoms could be among these particles. Avogadro's number has a value of approximately 6.022140857×10²³.

Computation of mass
Avogadro calculated that every material had 6.022 x 10^23 atoms per mole.

5.2 x 10^22 atoms of Mn would contain how many moles?
= 6.022 x 10^23 /1 x 5.2 x10^22
=11.58 moles

Mn mass equals 11.58 moles multiplied by 54.9
= 635.784 grams
