Explanation:

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.

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.

Answer:

Arginine is intermediate product formed during the production of urea

The key combination is ornithine, on which the urea molecule is 'created'; intermediates in the procedure contain citrulline and arginine.

The urea cycle is a procedure of conversion of toxic ammonia to negligibly toxic urea. Consequences of the urea cycle are 1 molecule of urea, 2 molecules of ADP, and 1 molecule of both AMP and fumaric acid.

When Ammonia and carbon dioxide recovery During urea decomposition a mixture of gaseous carbon dioxide and also ammonia is accumulated and also immersed into a dilute aqueous urea resolution.

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%

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.

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

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

Answer:

The number of neutrons in nucleus

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

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

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

       % 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%
