Answer:

Coal

Explanation:

Coal is by far the worst emitter, followed by natural gas, with solar, wind and nuclear all low-carbon.

Coal, a non-renewable energy source releases the most carbon dioxide into the atmosphere.

Energy sources refers to the various sources in which energy for man's needs are obtained.

There are two types of energy sources:

The non-renewable energy sources such as coal release large amounts of carbon dioxide until The atmosphere.

Therefore, Coal, a non-renewable energy source releases the most carbon dioxide into the atmosphere.

Answer:

A.

Explanation:

A wave is a disturbance that moves energy from one place to another. Only energy — not matter — is transferred as a wave moves. The substance that a wave moves through is called the medium. That medium moves back and forth repeatedly, returning to its original position. But the wave travels along the medium

Answer:

the average speed of [tex]V_{av} CO_2[/tex] is 5.24 ×  104 cm/s

Explanation:

The computation of the average speed of a [tex]CO_2[/tex] is as follows:

[tex]\sqrt{average} = \sqrt{\frac{8 RT}{\pi M} }[/tex]

where,

M = Molar mass

[tex]V_{av} = \frac{\sqrt{1}}{M}[/tex]

Given that

[tex]V_{av} \ of\ oxygen= 6.14 \times 10^4 cm/s[/tex]

The molar mass of oxygen i.e. (MO_2) = 31.9988 g/mol

And, the molar mass of CO_2 is  44.0098 g/mol

Now

[tex]\frac{V_{av} CO_2}{V_{av} O_2} = \frac{\sqrt{M_{O2} }}{M_{CO2}}[/tex]

Now place these values to the above formula

[tex]\frac{V_{av}CO_2}{6.14\times 104 cm/s} = \frac{\sqrt{31.9988} }{44.0098}[/tex]

So,

V_av CO_2 is 5.24 ×  104 cm/s

hence, the average speed of [tex]V_{av} CO_2[/tex] is 5.24 ×  104 cm/s

Answer:

6.50 mol

Explanation:

The question is incomplete but I looked it up on the web.

How many moles of water are produced when 3.25 moles of CO₂ are formed during the combustion of methyl alcohol (CH₃OH)?

Step 1: Write the balanced equation

2 CH₃OH +  3 O₂ → 2 CO₂ + 4 H₂O

Step 2: Establish the appropriate molar ratio

According to the balanced equation, the molar ratio of CO₂ to H₂O is 2:4.

Step 3: Calculate the moles of water formed with 3.25 moles of carbon dioxide

We will use the established molar ratio.

3.25 mol CO₂ × (4 mol H₂O/ 2 mol CO₂) = 6.50 mol H₂O

Answer: Adenine and guanine are the two purines and cytosine, thymine and uracil are the three pyrimidines. The main difference between purines and pyrimidines is that purines contain a sixmembered nitrogencontaining ring fused to an imidazole ring whereas pyrimidines contain only a sixmembered nitrogencontaining ring. They both are types or categories of nitrogen containing bases present in nuclei acids of DNA and RNA.

Purines are 2 Ring or Carbon Ring, Nitrogen containing bases. That consist of these 2 rings next placed next to each other. These examples include - Adenine and Guanine.

Pyrimidines are 1 or single Ring Nitrogen containing structures. There are 3 nitrogenous bases that are categorized as pyrimidines. Cytosine, Thymine, and Uracil.

Answer:

B) Na3BO3.

Explanation:

Hello!

In this case, since percent compositions are used to identify the empirical formula of an unknown compound, we can assume we have 54.0 g of sodium, 8.50 g of boron and 37.5 g of oxygen, and we compute the moles of each one:

[tex]n_{Na}=54.0g*\frac{1mol}{23g} =2.35mol\\\\n_B=8.50g*\frac{1mol}{11g}=0.773mol\\\\n_O=37.5g*\frac{1mol}{16g}=2.34mol[/tex]

Now, we divide by the moles of boron as those are the fewest:

[tex]Na:\frac{2.35}{0.773}=3\\\\B:\frac{0.773}{0.773}=1\\\\O=\frac{2.34}{0.773}=3[/tex]

Thus, the empirical formula is B) Na3BO3.

Answer:

the change in internal energy of the gases is  -3.0924 KJ

Explanation:

The computation of the change in internal energy of the gases is as follows;

Given that

Q = -3.1 KJ

= -3100 J

It is negative as the heat is lost from the mixture

And,

W = + 7.6 J

It is positive as the work is done in the mixture

Now we use the following equation

Delat E = Q + W

= -3100 J + 7.6 J

= -3092.4 J

= -3.0924 KJ

Hence, the change in internal energy of the gases is  -3.0924 KJ

Answer:

A 7.59 mol Ne

Explanation:

The number of moles of Ne in a sample of 4.57 x 10²⁴ atoms of neon (Ne) are 7.59 mol of Ne. Hence Option (A) is the correct option. It can be solved with the help of Mole concept.

The mole, symbol mol, is the SI base unit of amount of substance.

The quantity amount of substance is a measure of how many elementary entities of a given substance are in an object or sample.

n = given number / Avogadro's number

  = 4.57 x 10²⁴ / 6.022 x 10²³

  = 7.59 mol of Ne

Therefore, The number of moles of Ne in a sample of 4.57 x 10²⁴ atoms of neon (Ne) are 7.59 mol of Ne. Hence Option (A) is the correct option. It can be solved with the help of Mole concept.

Answer

Incidentally, they all form dew but because grass is closer to the soil, which maintains heat longer than the air where tree leaves are found, you will find more condensation in that region. Also, higher up the wind and sun will allow faster evaporation which makes the dew less noticable on tree leaves.

Explanation:

Preferred objects of dew formation are thus poor conducting or well isolated from the ground, and non-metallic, while shiny metal coated surfaces are poor infrared radiators. ... If the wet soil beneath is the major source of vapor, however (this type of dew formation is called distillation), wind always seems adverse.

Answer:

Nuclear fusion is when two atomic nuclei combine and form one nucleus. Nuclear fusion generates all of the Sun's energy. Inward pulling by the Sun's gravity is counteracted by outward pushing by the Sun's nuclear fusion; this balance keeps the sun from collapsing or exploding.

My wife and I just visited the City of Baguio for a week. We stayed at the Hotel Supreme Convention, which was very nice. We ate dinner at some really nice places: Mario's (expensive), Don Henrico's (mid), and Good Taste (cheap). We found a nice bar called the Old Bohemian for good live music. We ventured out toward Camp John Hay a couple of times for shopping(the commissary is a tourist trap with retail prices). We also did some street shopping.
