What is sugar?

Sugar is the generic term for a variety of sweet-tasting, soluble sugars, many of which are utilized in food. Glucose, galactose, and fructose are examples of simple sugars, often known as monosaccharides.

Disaccharides comprise sugars (carbohydrate compounds) created when two simple sugars, or monosaccharides, combine to create a disaccharide.

Polysaccharides, also known as polycarbohydrates, are among the most common carbohydrates present in foods. They are polymeric long-chain carbohydrates made up of monosaccharide units linked together by glycosidic bonds.

Therefore, monosaccharide is the term which  describes the given sugar.

If I have an unknown quantity of gas held at a temperature of 1195 K in a container with a volume of 25 liters and a pressure of 1,000 atm, how many moles of gas do I have?

Answers

I think you use PV= nRt.

So P=1000
V=25
We are trying to find the moles so n is blank.
R=0.08206
T=1195

This means that your equation is:

(1000)(25) = (n)(0.08206)(1195)

So you are gonna divide each side by (0.08206)(1195) because you are trying to get the moles by itself.

(0.08206)(1195) is gonna cancel each other out, so your new equation is going to be:

(1000)(25)/0.08206/1195 = n

Put that into your calculator and you get:

n= 254.941532

or 254.94moles

If i’m wrong please correct me.

1

Explanation:

The molarity of the hydrochloric acid solution is 1 M

Molarity is simply defined as the mole of solute per unit litre of water. Mathematically, it can be expressed as:

[tex]Molarity = \frac{mole}{volume}[/tex]

With the above information in mind, we can obtain the molarity of the hydrochloric acid solution as follow:

Mole of HCl = 3 moles

Volume of water = 3 L

Molarity =?

[tex]Molarity = \frac{mole}{volume}\\Molarity = \frac{3}{3}\\Molarity = 1 M[/tex]

Therefore, the molarity of the hydrochloric acid solution is 1 M.

Answers

the answer is B i believe

Scientists decided that Pluto are more in common with than the original 8 planets of the solar system will be the other, newly discovered, dwarf planets. Option A is correct.

In 2006, scientists redefined the definition of a planet, leading to the reclassification of Pluto as a dwarf planet. This decision was influenced by the discovery of other celestial bodies in the outer regions of the solar system that shared similar characteristics with Pluto.

The other, newly discovered, dwarf planets" is correct. Scientists recognized that there were other objects in the solar system, such as Eris, Haumea, Makemake, and Ceres, that shared similar characteristics with Pluto and were classified as dwarf planets alongside Pluto.

This reclassification highlighted the presence of a population of objects in the outer regions of the solar system known as the Kuiper Belt, which consists of numerous icy bodies similar to Pluto. By considering the properties and characteristics of these newly discovered dwarf planets, scientists concluded that Pluto had more in common with these objects than with the original eight planets of the solar system.

The moon and the asteroids are not accurate. While the moon and asteroids are significant celestial objects in the solar system, they do not represent the specific group of objects that are considered dwarf planets and have characteristics similar to Pluto.

Hence, A. is the correct option.

Answers

Answer:

B. increases the relative concentration of uranium-235 to 30-50% to avoid a nuclear explosion at higher percentages.

Explanation:

Uranium enrichment may be defined as a process which is necessary for creating effective nuclear fuel from the mined uranium by mainly increasing the percentage of the uranium-235 that undergoes fission with a thermal neutrons.

The enrichment process removes the unwanted uranium-238, thus making uranium 235 concentration higher. It takes up much work to increase the relative concentration of the uranium 235 to make it 30% to 50% so as to avoid a nuclear explosion at such higher percentages.

Explanation:

Use the dilution equation M1V1 = M2V2

M1 = 18 M

V1 = ?

M2 = 6.0 M

M2 = 250 mL

Solve for V1 --> V1 = M2V2/M1

V1 = (6.0 M)(250 mL) / (18 M) = 83 mL

Indicate which aqueous solution has the highest boiling point elevation. (Kb for water = 0.512 °C/m)

Answers

Answer:

carbon tetrachloride

Explanation:

Boiling point elevation of a liquid or a compound is defined as the boiling point of a liquid that is that will be higher when some other other compound is added. It means that the solution has a higher boiling point than the solvent. When a non volatile solute is added to the pure solvent like water, it results in the highest boiling point elevation.

Carbon tetrachloride, Kb = 5.03°C/m shows highest boiling point elevation when it is used to make a 0.10 m non - electrolyte solution.

Calculate the molarity of a sugar solution if 4 liters of the solution contains 12 moles of sugar.

Answers

Answer:

3M

Explanation:

Molarity is one of the measures of the molar concentration of a solution, which can be calculated by using the formula below:

Molarity = number of moles ÷ volume

From the information given in this question, 4 liters of a solution contains 12 moles of sugar. This means that n = 12mol and V = 4L

Molarity = n/V

Molarity = 12/4

Molarity = 3

Hence, the molarity of the sugar solution is 3mol/L or 3M

How many grams are there in 2.5 moles of C2H5OH?

Answers

2.5 mol C2H5OH x (46.0g C2H5OH / 1 mol C2H5OH) = 115g C2H5OH

2.5 moles of  C2H5OH would be 115.175 grams of the same compound.

Recall that:

Mole = mass/molar mass

Hence,

mass = mole x molar mass

Molar mass of  C2H5OH = 46.07

Mass of 2.5 moles of  C2H5OH = 2.5 x 46.07

                                                     = 115.175 grams

There is a very slight change in gravity at the top of a mountain. Which property would most likely be less at the top of a mountain?


mass

weight

body density

body temperature

Answers

Answer:

The entity that decreases is the Weight.

Explanation:

Every object on the surface of the earth is usually pulled downwards by the action of gravity. The force or weight is W = mg

Now, the farther one gets away from the surface of the earth by climbing a mountain, the further the person is from the Earth's centre of gravity.

We know that the formula for Force of gravity away from the Earth's surface is given by;

F_g = GM1M2/r²

So the greater the distance, the lesser the gravitational force.

Now, the gravitational force equals the weight of the individual.

Thus, the entity that decreases is the Weight of the individual.

If you have 730 moles of a gas at 304 Kelvin in a 4.50 Liter container what
is the pressure of that eas in atmospheres?

Answers

Answer:

4046atm

Explanation:

For this question you can use the ideal gas law,

[tex]PV=nRT[/tex]

Where P is pressure, V is volume, n is moles of substance, R is the constant, and T is the temperature.

Because of the units given, R will equal .08026[tex]P=4046 atm[/tex]

Rearrange the equation to solve for pressure:

[tex]P=\frac{nRT}{V}[/tex]

Then, plug in the values (I'll be excluding units for simplicity, but they all cancel out for pressure in atm):

[tex]P=\frac{(730)(.08206)(304)}{4.5}[/tex]

This will give you:
