Which of the following setups will correctly convert 36.45 grams of sodium to moles of sodium?

Answer:

83 mL

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

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.

Explanation:

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

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

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

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.  

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.

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.

Explanation:

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

a term for disaccharides would be double sugar or boise!

monosaccharides are simple sugars soluble in water. any class of sugars like glucose.

polysaccharide is starch, cellulose, or glycogen. with molecules together. a carbohydrate.

saccharide knows as to the term structure of carbohydrates. carbohydrates are plain simple? organic compounds that are aldehyde or ketone functional group. with the general chemical formula of carbohydrates is c (H O)

n. 2. n

To solve this we must be knowing each and every concept related to monosaccharide, polysaccharide and disaccharide. Therefore, monosaccharide is the term which  describes the given 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.

Answer:

The difference between mass and weight is that mass is the amount of matter in a material, while weight is a measure of how the force of gravity acts upon that mass. Mass is the measure of the amount of matter in a body. Mass is denoted using m or M.

Explanation:

the different between mass and weight is that the weight is the measure of the force of gravity on an object and the mass of an object will never change ,but the weight of an iteam can change based on its location
