Find the mass in kilograms in 2.6 mol of C8H12 (which is called windowpane).

Answers

Considering the definition of molar mass,  the mass in 2.6 moles of C₈H₁₂ is 0.2808 kg.

Definition of molar mass

The molar mass of an atom or molecule is the mass of one mole of that particle expressed in grams.

The molar mass of a compound is the sum of the molar mass of the elements that form it multiplied by the number of times they appear in the compound.

Mass of 2.6 mol C₈H₁₂

Being the molar mass of C₈H₁₂ 108 g/mole, you can apply the following rule of three: If by definition of molar mass 1 mole of the compound contains 108 grams, 2.6 moles of the compound contains how much mass?

mass= (2.6 moles× 108 grams)÷ 1 mole

mass= 280.8 grams= 0.2808 kg (being 1000 gr= 1 kg)

Finally, the mass is 0.2808 kg.

A student standardized a solution of NaOH and found that the concentration was 0.544 M. They then used it to titrate a monoprotic acid. If 45.50 mL of the base was used, how many moles of acid were neutralized? (Do not report your answer in scientific notation)

Answers

The number of moles of a monoprotic acid neutralized is equal to 0.025 mol.

What is a neutralization reaction?

A neutralization reaction can be defined as a reaction in which reaction of an acid and base generates salt and water. When a strong acid and a strong base react the salt can be neither acidic nor basic.

When monoprotic acid HA reacts with NaOH (a strong base), the resulting salt is NaA and water.

HA    +    NaOH   →   NaA  +   H₂O

Given, the concentration of NaOH = 0.544 M

The volume of the NaOH = 45.50 ml = 45.50 × 10⁻³

The number of moles of NaOH, n = M × V = 0.544 × 45.50 × 10⁻³ = 0.025 mol

The number of moles of HA monoprotic acid = moles of NaOH = 0.025 mol

By beta, tungsten 188 decays. The mechanism through which an insecure atomic structure is produced is known as radioactive decay.

How does radioactive decay work?

The process through which highly unstable molecular nucleus loses its energy through radiation is described as radioactive decay, also characterized as nuclear decay, radiography, radioactivity breakdown, or nuclear disintegration. A substance that has unstable nuclei is regarded as radioactive. For a large variety of human activities, radioactive decay is crucial.

What occurs when radioactive material decays?

Alpha, beta, and/or gamma rays are all types of ionizing radiation that are released when radioactive atoms decay.

calculate the percent of copper in copper oxide​

Answers

Answer:

To calculate the percent of copper in copper oxide, you would need to know the mass of copper in the compound and the mass of the compound itself. Once you have this information, you would divide the mass of copper by the mass of the compound and multiply by 100 to express the result as a percentage.

Example:

If the mass of copper in copper oxide is 40 grams and the mass of the compound is 100 grams, the percent of copper in the compound would be:

(40/100) * 100 = 40%

In PbO + 2HCl → PbCl2 + H20,13 g of lead oxide is
mixed with 6.4g of hydrochloric acid to produce lead chloride
and water. Which of the following is true?

Answers

Answer:

HCl acts as an excess reagent

Explanation:

The reaction equation is;

PbO + 2HCl → PbCl2 + H20

Number of moles of PbO = 13g/223.2 g/mol = 0.058 moles

Since the mole ratio is 1:1, 0.058 moles of PbCl2 is produced

Number of moles of HCl = 6.4 g/36.5g/mol = 0.175 moles

2 moles of HCl yields 1 mole of PbCl2

0.175 moles yields 0.175 moles * 1/2

= 0.0875 moles of PbCl2

Hence; PbO yields the least number of moles of product so it is the limiting reactant and HCl is the reactant in excess

What type of rock commonly often contains gas bubbles and the mineral(s) hornblende, muscovite, olivine, lucite, and/or plagioclase?

Answers

Igneous rock  commonly often contains gas bubbles and the mineral(s) hornblende, muscovite, olivine, lucite, and/or plagioclase.

What are igneous rocks?

Igneous rocks are rocks that form when molten rock cools and solidifies, either below the Earth's surface or on its surface. They are the oldest type of rocks on the planet and are composed primarily of crystals. Examples of igneous rocks include basalt, gabbro, granite, obsidian, pumice, and scoria.

Igneous rocks form from cooling and crystallizing molten rock, or magma. As the magma cools, minerals crystallize out of the molten material, forming the igneous rock. Hornblende, muscovite, olivine, lucite, and/or plagioclase are all common minerals that form as the magma cools, due to their high melting points. Gas bubbles may also form as the magma cools, creating a "vesicular" texture.

How many moles of aspartame are present in 4.50 mg mg of aspartame?

Answers

1.53 × 10⁻⁵ moles of aspartame are present in 4.50 mg of aspartame.

Two amino acids, aspartic acid and phenylalanine, make up the low-calorie sweetener known as aspartame. In addition to being present in tabletop sweetener packets, aspartame is a common component used to substitute sugar in low-calorie foods and beverages.

Here there are 4.50 mg of aspartame.

First, the mass is converted from mg to g by:

1 g = 1000 mg

So, 1 mg = 0.001 g

So, 4.5 mg = 4.5 × 10⁻³ g

Molar mass of aspartame = 294.40 g/mol

So, Number of moles of aspartame = [tex]\frac{Given mass}{Molar mass}[/tex]

or, n = 4.5 × 10⁻³ / 294.3

or, n = 1.53 × 10⁻⁵ moles.

Hence, 4.50 mg of aspartame has 1.53 × 10⁻⁵ moles of aspartame.

Answers

Ice will not melt as we need 16.72 KJ of heat but we have only 3.76 KJ

What is the enthalpy of fusion?

In thermodynamics, the enthalpy of fusion can be described as the change in its enthalpy resulting from giving energy, heat, to a specific amount to change its state from a solid to a liquid.

Given the reaction is  2 Na (s) + 2 H₂O(l) → 2 NaOH (aq) + H₂ (g)

Given the mass of sodium = 0.470 g

The moles of sodium = 0.470/23 = 0.020 mol

Given that two moles of sodium (Na) release heat = 368 KJ

Heat released by 0.020 mol of sodium (Na) = (368/2) × 0.020 = 3.76 KJ

Given the mass of ice = 50g

The number of moles = 50/18 = 2.78 mol

For melting, one mole of ice heat is required = 6.02 kJ/mol.

For 2.77 mol of ice = 6.02 × 2.78 = 16.72 KJ

But we have only 3.76 KJ of heat therefore, the ice will not melt.

What is the theoretical yield of water in this test reaction?

Answers

The theoretical yield of water in this reaction is 1 mole (18.015 grams) of water.

What is theoretical yield?

Theoretical yield is the amount of a product one would expect to yield from a reaction if it proceeds to completion, according to a balanced chemical equation. It is calculated by multiplying the limiting reactant by the molar ratio between the reactants and the products. The actual yield of a reaction is usually lower than the theoretical yield, due to a number of factors such as incomplete conversion of reactants to products, product losses, and impurities in the reactants. Theoretical yield is used to calculate the percentage yield of a reaction, which is the ratio of the actual yield to the theoretical yield multiplied by 100.

O Ethane, because its molecules can fit into the spaces between water molecules more easily than those of propanol can.
O Propanol, because its molecules have a greater mass than the molecules of ethane have.
O Propanol, because its molecules can form hydrogen bonds with water molecules.

Answers

Propanol, because its molecules can form hydrogen bonds with water molecules.

Reason:

Propanol contains a hydroxyl (-OH) group, which can form hydrogen bonds with the partially negative oxygen atoms in water molecules.This interaction increases the solubility of propanol in water.Ethane is a nonpolar hydrocarbon and it does not have any functional groups that can interact with water in this wayHydrogen bonding between propanol and water makes the solution more stable and thus more soluble.Nonpolar compounds like Ethane are not attracted to water molecules and are less likely to dissolve in them.

Therefore, propanol is more soluble in water than Ethane.

O-H

A water molecule is polar because the electrons are not shared equally between the oxygen and hydrogen atoms. Oxygen is more electronegative than hydrogen, so it pulls the electrons closer to itself, creating a partial negative charge on the oxygen side of the molecule and a partial positive charge on the hydrogen side. This causes the molecule to have a dipole moment and makes the molecule polar.

NH3 (Ammonia) - the molecule is a pyramidal shape, which means that the Nitrogen is at the center and the three hydrogen atoms are located at the three corners of a pyramid.
