Answers

Answer 1

Answer:

B. Ester

Explanation:

"Esters have the general formula RCOOR′, where R may be a hydrogen atom, an alkyl group, or an aryl group, and R′ may be an alkyl group or an aryl group but not a hydrogen atom."

Answer 2

The type of molecule is ester.

What is molecule?

A molecule is a collection of  more than one atom bound together by chemical bonds; based on the circumstances, the phrase will not include ions that meet this requirement.

What is ester?

Esters were chemical molecules formed by mixing an oxoacid and a hydroxyl substance like alcohol as well as phenol.

It can be seen that molecule have -COO group which represent ester group. Hence, given molecule have ester group.

Therefore, the correct answer will be option (B).

An unknown compound has the following chemical formula: NxO
where x stands for a whole number.
Measurements also show that a certain sample of the unknown compound contains 5.2 mol of nitrogen and 2.65 mol of oxygen
Write the complete chemical formula for the unknown compound.

Answers

Taking into account the definition of empirical formula, the complete chemical formula for the unknown compound is N₂O.

The empirical formula of a chemical compound shows the ratio between the atoms of the compound. That is, it indicates which elements are present and the minimum ratio in whole numbers between their atoms. The empirical formula is the simplest chemical formula for a chemical compound, which is why it is also called the minimum formula.

The empirical formula must be expressed using integer relationships, then to obtain this formula, divide the numbers of moles by the smallest result of them. In this case:

Nitrogen: [tex]\frac{5.2 moles}{2.65 moles}[/tex]= 1.96 moles ≅ 2 moles

Oxygen [tex]\frac{2.65 moles}{2.65 moles}[/tex]= 1 mole

Being the chemical formula of hte compound NxO, where x stands for a whole number, this indicates that the elements N and O are in the compound in a whole number ratio of x: 1.  Then, as in the empirical formula, the numbers of moles must be expressed in whole numbers, as previously calculated, the value of x must be 2.

In summary, the complete chemical formula for the unknown compound is N₂O.

calculate the volume in L od 2.11mol/L CuSo4(aq) solution that contains 0.41 mol copper(2) sulfate

Answers

Answer:

0.194L

Explanation:

Molarity of a solution is its molar concentration, and can be calculated using the formula:

Molarity = no. of moles (n) ÷ volume (V)

According to this question, the molar concentration/molarity of a solution of copper sulfate (CuSO4) is 2.11mol/L and contains 0.41 mol CuSO4. The volume can be calculated as follows;

Volume = no. of moles ÷ molarity

Volume = 0.41mol ÷ 2.11mol/L

V = 0.194 liter

Which of the following is true for the equilibrium constant of a reaction?

It is a ratio of the concentrations in a reaction.
It remains the same at different temperatures.
It is represented by the symbol H.
Its value is always close to 1.

Answers

Answer:

The correct answer is It is a ratio of the concentrations in a reaction.

Explanation:

⇒ It is a ratio of the concentrations in a reaction.

This sentence is true because the equilibrium constant is calculated from the product of the concentration of the reaction products divided into the product of the concentrations of the reactants, each concentration raised by the stoichiometric coefficient. For example, for the following reaction:

aA + bB → cC + dD

The equilibrium constant is expressed as:

[tex]K = \frac{[C]^{c}[D]^{d} }{[A]^{a} [B]^{b} }[/tex]

⇒ It remains the same at different temperatures.

The sentence is false because the equilibrium constant changes with the temperature. In general, an endothermic reaction is favored by the increment of temperature (the equilibrium shifts to the right side) and disfavored with the decrease in temperature (shifts to the left).

⇒ It is represented by the symbol H.

This sentence is false because the equilibrium constant is represented with the letter K.

⇒ Its value is always close to 1.

It is not true because the equilibrium constant can be a number below or above 1.

K < 1 ⇒ there is more concentration of reactants at equilibrium

K > 1 ⇒ there is more concentration of products at equilibrium

Calculate the mass percent of carbon,oxygen, nitrogen and hydrogen in acetamide, C2H5NO.
Molar Mass:
O=16, N=14,C=12, H =1.

Answers

Answer:

40.68 % C

23.73 % N

8.47% H

27.12% O

Explanation:

The mass percent of an element X in a compound is calculated as the molar mass (MM) of X multiplied by the number of atoms of X in the compound, divided into the molecular weight (MW) of the compound, as follows:

mass percent of X = (MM(X) x number of atoms of X)/MW compound x 100

Thus, we first calculate the MW of acetamide (C₂H₅NO) by using the molar mass of the chemical elements C, H, N and O:

MW(C₂H₅NO) = (12 g/mol C x 2) + (1 g/mol H x 5) + 14 g/mol N + 16 g/mol O = 59 g/mol

Now, we can calculate the mass percent of each element (C, H, N, O) in C₂H₅NO:

Mass percent of C (2 atoms of C in 1 molecule of C₂H₅NO):

          % mass C = (12 g/mol x 2)/(59 g/mol) x 100 = 40.68 %

Mass percent of N (1 atom of N in 1 molecule of C₂H₅NO):

       % mass N = (14 g/mol x 1)/(59 g/mol) x 100 = 23.73 %

Mass percent of H (5 atoms of H in 1 molecule of C₂H₅NO):

       % mass H = (1 g/mol x 5)/(59 g/mol) x 100 = 8.47 %

Mass percent of O (1 atom of O in 1 molecule of C₂H₅NO):

       % mass O = (16 g/mol x 1)/(59 g/mol) x 100 = 27.12 %

The sum of the mass percents has to be equal to 100%:

40.68 % C + 23.73 % N + 8.47% H + 27.12% O = 100%

El tipo de enlace en los compuestos: NaF , SO2 e I2 ,son respectivamente de acuerdo a sus electronegatividades que son las siguientes: Na = 0.9 F= 4.0 S= 2.6 I =2.7 F=4.0

Answers

Respuesta:

NaF: Enlace iónico

SO₂: Enlace covalente polar

I₂: Enlace covalente apolar

Explicación:

El tipo de enlace entre 2 elementos depende de la diferencia de electronegatividad.

Si ΔEN = 0, el enlace es covalente apolar.Si 0 < ΔEN ≤ 1.7 , el enlace es covalente polar.Si ΔEN > 1.7 , el enlace es covalente iónico.

NaF

ΔEN = |EN(Na)-EN(F)| = |0.9-4.0| = 3.1

El enlace es iónico.

SO₂

ΔEN = |EN(S)-EN(O)| = |2.6-3.5| = 0.9

El enlace es covalente polar.

I₂

ΔEN = |EN(I)-EN(I)| = |2.7-2.7| = 0

El enlace es covalente apolar.

2. Sulfur dioxide gas (SO2) reacts with excess oxygen gas (O2) and excess liquid water (H2O) to form liquid sulfuric acid (H2SO4). In the laboratory, a chemist carries out this reaction with 67.2 L of sulfur dioxide and gets 250 g of sulfuric acid.
• Write a balanced equation for the reaction.
• Calculate the theoretical yield of sulfuric acid.
• Calculate the percent yield of the reaction.
(One mole of any gas occupies 22.4 L under certain conditions of temperature and pressure. Assume those conditions for this question.)

Answers

Answer:

See explanation

Explanation:

The balanced equation for the formation of sulphuric acid is;

2SO2 + O2 + 2H2O → 2H2SO4

If 1 mole of SO2 occupies 22.4 L

x moles occupy 67.2 L

x = 1 × 67.2/22.4

x= 3 moles

From the reaction equation;

2 moles of SO2 yields 2 moles of H2SO4

Hence 3 moles of SO2 also yields 3 moles of H2SO4

Theoretical yield of H2SO4 = 3 moles × 98 g/mol = 294 g

Percent yield = actual yield/theoretical yield × 100

Percent yield = 250g/294g × 100

Percent yield = 85%
