Answer:

Option (A)

Explanation:

The resources that can be regenerated again over a specific period of time are known as renewable resources. For example, Wind, Water, and Sunlight.

Water is one of the most necessary and valuable renewable resources. It is considered to be renewable because it can be obtained again and again by undergoing certain processes that form a cycle which is commonly known as the water cycle.

In the water cycle, the water moves from the surface to the atmosphere in the form of vapor by undergoing the process of evaporation and transpiration and comes back to the surface in the form of rainfall, by undergoing the process of condensation.

This is how water changes its phase from one type to another, recycling within the system, thereby regenerating it. So, water is usually classified as a renewable resource.

Thus, the correct answer is option (A).

If a mixture containing 0.50 moles of N2 and 1.8 moles of H2 is allowed to react according to the equation N2 3H2 2NH3 Group of

Lelechka [254]

Answer: hydrogen is the limiting reactant.

Explanation:

We have the equation $\text{N}_{2}+3\text{H}_{2} \longrightarrow 2\text{NH}_{3}$ .

This means that for every mole of nitrogen consumed, 3 moles of hydrogen are consumed.

Considering the nitrogen, the reaction can occur 0.50 times.
Considering the hydrogen, the reaction can occur 1.8/3 = 0.6 times.

Therefore, <u>hydrogen</u> is the limiting reactant.

The empirical formula of a group of compounds is CHCl. Lindane, a powerful insecticide, is a member of this group. The molar mas

Sergeeva-Olga [200]

Answer:

Explanation:

since, n = molar mass / empirical formula mass

Empirical formula mass = Total mass of atoms present in empirical formula

CHCl = 12+1+35.5

= 48.5

Given, Molar mass = 290.8 g.

So, n = 290.8/48.5

= 5.995 , that is approx 6.

So, Molecular formula = n × Empirical formula

= 6 × CHCl

= $C_{6}H_{6}Cl_{6}$

So, Number of C = 6

The following two structures would be considered isomers.<br> Select one:<br> O True<br> O False

Nat2105 [25]

Answer:

False

Explanation:

Isomerism is a phenomenon where by two or more compounds have the same molecular formula but different structural patterns. The compounds involved are called isomers.

Now, let us consider the molecular formula of the two compounds given in the question above.

The two compounds given in the question above have different molecular formula

Benzene has molecular formula as C6H6

Cyclohexane has molecular formula as C6H12.

Since their molecular formula are different, therefore, they are not isomers..
