What is freshly pumped oil called?

Answer:

6.6242 x 10 ^ 24

Explanation:

This is the correct answer because you know there is 11 oxygen moles in 1 mole of sugar so using dimensional analysis you can solve it. You start will 11 moles of oxygen, and multiply by Avogadro's number(6.022 x 10 ^23) to get the amount of atoms. I don't see it as an answer, but I am confident in this, so I would ask your teacher specifically.

Hope this helps!

Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, 4.42g of aluminum must react with 100 g of copper (ii) phosphate.

The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity or amount of substance. We know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number.

Mathematically,

mole =given mass ÷ molar mass

2 Al + 3 Cu[tex]_3[/tex](PO[tex]_4[/tex])[tex]_2[/tex] → Al[tex]_2[/tex] (PO[tex]_4[/tex])[tex]_3[/tex]+ 3 Cu

moles of copper phosphate= 100 g/380.58

                                               =0.26 moles

3 moles of copper sulphate need 2 mole of Al

0.26 moles of copper sulphate need (2/3)×0.26

                                                         =0.17moles

mass of Al= 0.17×26

                  =4.42g

Therefore, 4.42g of aluminum must react with 100 g of copper (ii) phosphate.

Answer:

I'm pretty sure its just the mass of the sample divided by the molar mass

for example if I had like 7g of carbon and wanted to find the moles, I would divide the mass I have (7g) by the molar mass (the atomic mass value on your periodic table, in this case for carbon it would be 14g)

moles = [tex]\frac{mass}{molarmass} = \frac{7}{14} = 0.5\ moles[/tex]

Answer:

The strongest intermolecular force in sulfur dioxide is dipole-dipole forces.

Explanation:

The interparticle force in [tex]SO_{2}[/tex] (sulfur dioxide) is the dipole-dipole interaction.

Dipole-dipole interaction is a type of intermolecular force that occurs between polar molecules. Polar molecules have a permanent dipole moment, which means they have a partial positive charge on one end and a partial negative charge on the other end. This creates an electrostatic attraction between the partial charges of neighboring molecules. The stronger the dipole moment of a molecule, the stronger its dipole-dipole interaction will be with other polar molecules.

Dipole-dipole interactions are responsible for a variety of physical properties of substances, including their boiling and melting points. Substances with strong dipole-dipole interactions tend to have higher boiling and melting points than substances with weaker interactions. In addition, the strength of dipole-dipole interactions can affect solubility, as polar substances tend to dissolve better in other polar substances due to their ability to form dipole-dipole interactions.

Answer: 0.28 mol H2

Explanation:

0.57mol HCl         1mol H2          

                             2mol Hcl

Hydrochloric acid and zinc show the displacement reaction to produce hydrogen gas and zinc chloride. 0.57 moles of hydrochloric acid and excess zinc react to produce 0.28 mol H₂.

A displacement reaction is the removal of one of the elements from the reactant with highly active species of the reactivity species to produce the products. It can be a single or double displacement reaction.

The balanced chemical displacement reaction is given as:

2 HCl + Zn → H₂ + ZnCl₂

Here, two hydrochloric acids react with zinc to form one mole of hydrogen gas and one mole of zinc chloride.

Given,

Hydrochloric acid = 0.57 moles

Using proportions to calculate moles as:

If 2 moles of HCl = 1 mole H₂

Then, 0.57 moles = X moles

X = 0.57 ÷ 2

= 0.28 mol H₂

Therefore, 0.57 mole HCl produces 0.28 moles of hydrogen gas.

The mass of a 0.513 mol of Al2O3 is 52.33g.

HOW TO CALCULATE MASS:

The mass of a substance can be calculated by multiplying the molar mass of the substance by its number of moles. That is;

mass of Al2O3 = no. of moles of Al2O3 × molar mass of Al2O3

According to this question, there are 0.513 moles of Al2O3.

Mass of Al2O3 = 0.513 × 102

Mass of Al2O3 = 52.33g

Therefore, the mass of a 0.513 mol of Al2O3 is 52.33g.

Electrical Energy is the useful type of energy produced in an electric toothbrush.

If input energy is equal to useful output energy. This means that the total amount of energy that is in an isolated system (such as an engine or a generator) remains constant (conserved) over time.

However, the total amount of useful energy output of an isolated system is never equal to the total energy input.

Explanation:

Answer: V2= 41.2mL

Explanation:

Givens:

* V1= 20ml

* T1 = -109 ⁰C --> K= ⁰C + 273.15 --> 164.15 K

* V2 = ??

* T2= 338.15 K

Use Charles law V1/T1 = V2/T2

Since we are looking for V2 we can rearrange the formula to

V2= (T2 x V1) /T1

V2= (338.15K x 20mL) / 164.15 K

V2= 41.2mL

NOTE:

Temperature should always be in K not in ⁰C or ⁰F

To convert from C to K use

*K= ⁰C + 273.15

Enter your C value in the ( ⁰C ) and you can get K
