Resources can be renewable or nonrenewable based on their replenishing power. Some renewable energy sources are wind, water, and solar energy, and nonrenewable is natural gas, coal, diesel, etc.

<h3>What are renewable and non-renewable sources?</h3>

Renewable resources are the things that can get refilled when they are utilized for the purpose. Nonrenewable resources are the sources that have a short existing period of life.

Some examples of renewable resources are wind, air, groundwater, solar energy, timber, soil, etc. Some nonrenewable resources are coal, petrol, diesel, natural gas, etc.

Renewable resources are present for an infinite time period while the non-renewable get depleted when excessively used. Renewable has less environmental impact than nonrenewable sources as they lack harmful chemicals that causes the environmental imbalance.

Therefore, nonrenewable resources are harmful to the environment compared to renewable resources.

How many moles of NH3 can you make from 0.37 moles of H2
uranmaximum [27]

Answer:

The correct answer is 0.25 moles NH₃

Explanation:

First, we need to know the chemical equation for NH₃ formation from H₂. The balanced chemical reaction involved in NH₃ obtention is the following:

N₂(g) + 3 H₂(g) → 2 NH₃(g)

According to this, 2 moles of NH₃ are formed from 3 moles of H₂. We can write that estequiometrical relation as: 2 moles NH₃/ 3 moles H₂.

From the problem, we have to calculate how many moles of NH₃ are produced from 0.37 moles H₂. So, we can simply multiply the number of moles of H₂ to obtain by the convertion factor:

0.37 moles H₂ x 2 moles NH₃/ 3 moles H₂= 0.246 moles NH₃ ≅ 0.25 moles NH₃

Thus, 0.25 moles of NH₃ will be obtained.

The total number of valence electrons in the phosphate ion is
Vitek1552 [10]

Answer:

32

Step-by-step explanation:

There are two ways you can count the valence electrons.

A. From the Periodic Table

1 × P (Group 15)               =   5

4 × O (Group 16) = 4 × 6 = 24

+3 e⁻ (for the charges)   = <u>  3</u>

                              Total = 32

B. From the Lewis structure

In the <em>Lewis structure</em> (below), each line (bond) represents a pair of bonding electrons, and each dot represents an unbound electron (half a lone pair).

5 lines (bonds)                    = 5 × 2 = 10

3 single-bonded O atoms = 3 × 6 = 18

1 double-bonded O atom              = <u>  4</u>

                                              Total = 32
