Answer:

1.5 mol

Explanation:

Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, 1.50moles are there in  95.33 grams of  copper. The correct option is option A.

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. The stoichiometry represents the number of moles.

Mathematically,

number of moles of copper=given mass of copper÷ molar mass of copper

Molar mass of 1 mole of copper=63.55g/mol

mass of copper=95.33g

Substituting all the given values in the above equation, we get

number of moles of copper=95.33/63.55

number of moles of copper =1.50moles

Therefore, 1.50 moles are there in  95.33 grams of  copper. The correct option is option A.

Answer:

[tex]\lambda=10^{12}\ m[/tex]

Explanation:

Given that,

The frequency of the light, [tex]f=3\times 10^{-4}\ Hz[/tex]

We need to find the wavelength of the light.

The relation between frequency, wavelength and the speed of light is given by :

[tex]c=f\lambda\\\\\lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3\times 10^8}{3\times 10^{-4}}\\\\\lambda=10^{12}\ m[/tex]

So, the wavelength of the light is [tex]10^{12}\ m[/tex].

The wavelength of light will be "[tex]10^{12} \ m[/tex]"

Given:

By using the relation,

→ [tex]\lambda = \frac{c}{f}[/tex]

By putting the values, we get

→    [tex]= \frac{3\times 10^8}{3\times 10^{-4}}[/tex]

→    [tex]= 10^{12} \ m[/tex]

Thus the above response is right.

Answer:

0.214 M.

Explanation:

The equation showing the balanced chemical reaction between HCl and NaOH is given below;

HCl + NaOH ------------------> NaCl + H​​​​​​2​​​​O

Therefore, in entry one(1) the volume of HCl solution is 10mL and the volume of NaOH solution is 21.5 mL. Hence, the molarity of HCl solution is given below;

NB: the molarity of NaOH = 0.1 M.

The molarity of HCl = molarity of NaOH × volume of NaOH/ volume of HCl solution.

The molarity of HCl = 0.1 × 21.5 / 10 = 0.215 M.

For entry two(2), the volume of HCl solution is 10mL and the volume of NaOH solution is 21.3 mL. Hence, the molarity of HCl solution is given below;

The molarity of HCl =0.1 × 21.3 / 10 = 0.213 M.

For entry three(3), the volume of HCl solution is 10mL and the volume of NaOH solution is 21.43 mL. Hence, the molarity of HCl solution is given below:

Molarity of HCl = 0.1 × 21.43 / 10 = 0.2143 M.

Therefore, let's take the average of all the molarities of HCl in the three entries.

Hence, 0.215M + 0.213M + 0.2143M / 3 = 0.214 M.

Answer:Because When you're cleaning your glassware, you use water to rinse it off. If the burette is not completely dry by the time you use it, the remaining traces of water on the inside will make your titrant more dilute and thereby change its concentration.Before a burette is used, it needs to be cleaned. During the cleaning process, usually, water is introduced into the burette. Be the water clean or not, if the burette is then used without rinsing it with the solution that it is going to be filled with, the result of that analytical exercise will not be precise and accurate. The reason is that water residue in the burette would dillute the solution when it's filled in the burette which would make it impossible to determine the exact concentration of the solution moved by the burette. By rinsing and re-rinsing the burette several times with the solution it is going to be filled with, residue water from the cleaning process would be successfully removed from the burette as are other leftover substances from the cleaning process.

Answer:

I believe the answer for this is A

Answer:

Isopropyl has the specific orientation of being attached to a central carbon atom with two CH3 molecules attached (so in IUPAC naming it can become dimethylethyl), whereas propyl is three carbons all attached in a line branching off the main carbon chain, so it's two CH2 molecules and one CH3 molecule.

Explanation:

n-propane are longer chain hydrocarbon whereas isopropane is branched hydrocarbon. Isopropyl radical is more stable than n-propyl radical.

Radicals are reaction intermediates containing one unpaired electron. They are highly reactive species . The stability of radicals depends on the structure and reaction condition.

n -propyl radical is  CH₃-CH₂-CH₂·

Isopropyl radical  is written as CH₃-CH·-CH₃

The isopropyl group contains a branch in the second carbon and its makes the central carbon with secondary structure.

The stability of tertiary radicals is greater than secondary which is greater than primary. Therefore, isopropyl radical is more stable than n -propyl radical.

Answer:

210 moles

Explanation:

From the question given above, the following data were obtained:

Volume of solution = 25.6 L

Molarity = 8.20 M

Mole of solute =?

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

Molarity = mole /Volume

With the above formula, the mole of solute dissolved can be obtained as follow:

Volume of solution = 25.6 L

Molarity = 8.20 M

Mole of solute =?

Molarity = mole /Volume

8.20 = mole / 25.6

Cross multiply

Mole = 8.20 × 25.6

Mole = 209.92 ≈ 210 moles

Thus, the mole of solute dissolved in the solution is 210 moles

Answer:

a) The mean repeat unit molar mass for PEVA is 30.72 g/mol

b) degree of polymerization of the copolymer is 1300

Explanation:

Given that;

the wt% of copolymer consist of 12.9 wt% of vinyl acetate and 87.1 wt% Ethylene.

Basis: 100 g of PEVA consist of 12.9 of vinyl acetate and 87.1g of Ethylene.

now we calculate the mole fraction of vinyl acetate Ethylene in the copolymer;

the molecular weights of vinyl acetate and ethylene are 86.09 g/mol and 28.05 g/mol respectively

so

moles of vinyl acetate = wt. of vinyl acetate / molecular weights of vinyl acetate

moles of vinyl acetate = 12.9 g / 86.09 g/mol

moles of vinyl acetate = 0.1498 mol

moles of Ethylene = wt. of Ethylene / molecular weights of Ethylene

moles of Ethylene = 87.1 g / 28.05  d/mol

moles of Ethylene  = 3.1052 mol

Total moles = 0.1498 mol + 3.1052 mol = 3.255 mol

Next we calculate the mole percent;

mole percent of vinyl acetate [tex]X_{V}[/tex] = moles of vinyl acetate / total  moles

[tex]X_{V}[/tex] = (0.1498 mol / 3.255 mol) × 100

[tex]X_{V}[/tex]  = 4.6%

mole percent of Ethylene [tex]X_{E}[/tex] = moles of Ethylene / total  moles

[tex]X_{E}[/tex]  = (3.1052 mol / 3.255 mol) × 100

[tex]X_{E}[/tex]  = 95.397% ≈ 95.4%

we know that, mean repeat unit molar mass for a sample = ∑[tex]X_{i}[/tex][tex]M_{i}[/tex]

where [tex]X_{i}[/tex] is the fraction ratio and [tex]M_{i}[/tex] is the molecular  weight

so or the PEVA

mean repeat unit molar mass M = ( [tex]X_{V}[/tex][tex]M_{V}[/tex]) + ( [tex]X_{E}[/tex][tex]M_{E}[/tex])

so we substitute

M = ( 4.6% × 86.09) + ( 95.4% × 28.05 )

M = 3.96014 + 26.7597

M = 30.72 g/mol

Therefore, The mean repeat unit molar mass for PEVA is 30.72 g/mol

b)

Degree of polymerization

[tex]DP_{n}[/tex] = [tex]\frac{M_{n} }{M}[/tex]

where [tex]M_{n}[/tex] is the number average molecular weight ( 39,870 g/mol )

so we substitute

[tex]DP_{n}[/tex] = 39,870 g/mol / 30.72 g/mol

[tex]DP_{n}[/tex]  = 1297.85 ≈ 1300   { 3 significance figure }

Therefore, degree of polymerization of the copolymer is 1300

M = n/V = 0.578 mol/0.850 L = 0.680 M

Answer:an element in a chemical equation is called a subscript.

Explanation:

it represents the the number of atoms of that element present in the compound. hope this helps have a great day yall

The number at the bottom right of an element in a chemical equation is called a subscript.

Subscripts represent the number of atoms of that particular element in a molecule or formula unit. They indicate the ratio of atoms or ions present in a compound. Subscripts are written in a smaller font size and appear slightly below the element's symbol.

For example:

In the chemical compound water [tex](H_2O)[/tex],the subscript '2' indicates that there are two atoms of hydrogen (H) bonded to one atom of oxygen (O). The subscript specifies the ratio of elements in the compound, indicating that there are two hydrogen atoms for every one oxygen atom in water.

Therefore, the term subscript refers to the number on the right of an element in a chemical equation.
