At constant pressure, the volume of a gas is directly proportional to temperature as measured on the kelvin temperature scale.

This is defined as the degree of hotness or coldness of a substance and is influenced by thermal energy.

The standard unit is Kelvin which also compares it to volume  at constant pressure of a given gas.

Answer:

In water, bases dissolve and provide hydroxide (OH-) to the surrounding solution. This lowers the acidity of the solution.

Answer: How much heat it takes to raise the temperature

Specific heat describes how much heat a substance takes to raise the temperature. Hence, Option (c) is correct

Specific heat capacity is the amount of heat energy required to raise the temperature of a substance per unit of mass.

The specific heat capacity of a material is a physical property.

It is also an example of an extensive property since its value is proportional to the size of the system being examined.

The compound which on combustion produces Carbon-di-oxide and water is carbohydrates.

Those reaction in which the Crabon present in the reatctant gets reacted with oxygen and produces Carbon-di-oxide.

It is an Exothermic Reaction.

To find out the percentage of C, H and O, we must know about there weight in the product.

Given,

Total weight of compund [Reactant] = 17.41 grams

Weight of carbon dioxide [Product] = 25.61 grams

Weight of water [Product]= 10.48 grams

Now, we need to find out the weight of C,H and O in the products ;

No. of Moles of Crabon =   [tex]\frac{Given \\ weight\\ of\\ the\\ compound}{Molecular\\ weight\\ of\\ the compound}[/tex] x No. of C-atoms in molecule                          

No. of Moles of Crabon =25.61 / 44 = 0.58 x 1 = 0.58 moles

Mass of Carbon = 0.58 moles x 12 = 6.98 gm

No. of Moles of Hydrogen =   [tex]\frac{Given \\ weight\\ of\\ the\\ compound}{Molecular\\ weight\\ of\\ the compound}[/tex] x No. of H-atoms in molecule                          

No. of Moles of Hydrogen =10.48/ 18 = 0.58 x 2 = 1.16 moles

Mass of Hydrogen = 1.16 moles x 12 = 15.08 gm

                                       =   17.41 grams - ( 15.08 gm + 6.98 gm)
Mass of Oxygen  = 4.6 gm

Now,

The Newman projection gives the view of the molecule. In molecule A the torsional strain and in B steric strain are present because of the gauche methyl group.

The Newman projection depicts the molecules in the head-on view and uses the letters and the lines to represent the molecule. The torsional strain is because of the molecule's resistance to the twisting.

The steric strain is the Vander wall strain that is due to the forced interaction of the molecules separated by covalent bonds resulting in molecular potential energy.

Answer:

I think a small spark can start a huge explosion because, a spark or a small firework for an example, can start a fire. You don’t want to have a spark or sparkler lit in your house. This is why I think that it could start a fire.

Explanation:

reasoning

My reason is that if you have a lighter, and you lite the sparkler or spark, you will definitely see a flame glowing at the top. One reason for why you need to lite things that could start fires outside is, that it can be deadly if you accidentally leave one inside or somewhere close to your house or a window. Another piece of evidence is one from a movie. This scenario is kind of like the one in a dogs purpose. A dog’s purpose is about how a dog begins there life as a puppy, they eventually end up having to be saved again by their owner but that’s the summary for just the small unimportant parts. But the real reason for why I’m comparing the question to this is because, in the movie, the rising action, is kind of when the dog, gets put to sleep. But after it goes on all different types of adventures both dangerous, boring at times, and then mood changing I think the story is similar to the question because, a adult sets a fire on the house and the owner of the dog and the owners mom have to get out with there dog. The owner that’s a boy or adult boy, has to jump out the window after saving his dog and this is how a small spark can make a huge impact or life changing lesson.

Answer:

81.08g of H[tex]_{2}[/tex]O will be produced.

Explanation:

Write down the balanced chemical equation:

[tex]B_5H_9 + O_2[/tex] ⇒ [tex]B_2O_3+H_2O[/tex]

[tex]2B_5H_9+12O_2[/tex] ⇒ [tex]5B_2O_3+9H_2O[/tex]

Determine the limiting reagent:

[tex]B_5H_9[/tex] :-    126/63.12646 = 1.995993 mol

               1.995993/2 = 0.9979965

[tex]O_2[/tex] :-         192/31.9988 = 6.000225 mol

               6.000225/12 = 0.50001875

Therefore, [tex]O_2[/tex], is the limiting reagent.

Use stoichiometry ratios to determine the number of moles of water produced:

         [tex]O_2[/tex]         :        [tex]H_2O[/tex]

         12          :          9

  6.000225   :       4,500168756328362

Use the mole formula to calculate the mass of water produced:

[tex]n=\frac{m}{M} \\m=nM\\m=(4.500168756328362)(18.01528)\\m=81.08g[/tex]

Food industries require that reaction rates be lowered and this can be done by addition of preservatives and by freezing food substances.

The rate of a reaction is a measure of amount of substances converted to products per unit.

Substances that speed up rate of reactions are known as catalysts.

Some catalysts though, reduce or slow down the rate of reactions.

An industry that requires the rate of reactions to slow down is the food industry.

The final concentration of a solution that has been diluted by adding 100 ml of water to the original solution is 0.15M.

How to calculate concentration?

The concentration of a solution can be calculated using the following formula:

C1V1 = C2V2

Where;

C1 = initial concentration

C2 = final concentration

V1 = initial volume

V2 = final volume

1.5 × 10 = 100 × C2

15 = 100C2

C2 = 0.15M

Therefore, the final concentration of a solution that has been diluted by adding 100 ml of water to the original solution is 0.15M.

The structure of the cytosine base after catalysis by DNMT is 5'Mecytosine.

Cytosine (C) is one of the four nucleotide bases in DNA, with the other three being adenine (A), guanine (G) and thymine (T).

Methylation of the cytosine base is catalyzed by the enzyme DNA methyltransferase (DNMT), and S-adenosyl methionine (SAM) functions as the methyl group donor.

Answer:

Explanation:

This will never naturally occur but you can tweak the system quantum mechanically to temporarily reverse entropy.

A gas at STP is heated to 35 degree C. The new pressure will be 2.41 atm.

The pressure of the mass of the gas is directly proportional; to the temperature of the gas.

[tex]\dfrac{P_1 }{T_1} =\dfrac{P_2}{T_2}[/tex]

Converting the temperature into kelvin

The initial temperature = 35 °C = 35 + 273 K= 308 K

The final temperature = 50 °C =50 + 273 K = 323 K

Initial pressure = 2.3 atm

Final pressure ?

Putting the values in the equation

[tex]\dfrac{P_1 }{T_1} =\dfrac{P_2}{T_2}\\\\\\{P_2 = \dfrac{P_1 \times T_2}{T_1} \\\\\\\\\\{P_2 = \dfrac{2.3 \times 323 }{308} = 2.41 atm.[/tex]

Thus, the new pressure will be 2.41 atm.
