Explanation:

Explanation:

Carbon has the ability to form long chains of carbon atoms as well as ringed compounds by continuously bonding to itself. This covalent bonds may be single, double, or triple. Carbon forms covalent bonds easily with other elements, especially hydrogen, oxygen, nitrogen, halogens, and a variety of nonmetals.

Answer:

[tex]\Delta H_{comb}=2043.85kJ/mol[/tex]

Explanation:

Hello there!

In this case, according to the given chemical reaction, it possible for us to set up the expression for the calculation of the enthalpy change as shown below:

[tex]\Delta H_r=-\Delta H_{comb}=3\Delta _fH_{CO_2}+4\Delta _fH_{H_2O}-\Delta _fH_{C_3H_8}-3\Delta _fH_{O_2}[/tex]

Thus, given the values of the enthalpies of formation on the attached file, we obtain:[tex]-\Delta H_{comb}=3(-393.5kJ/mol)+4(-241.8kJ/mol)-(-103.85kJ/mol)-3(0kJ/mol)\\\\-\Delta H_{comb}=-2043.85kJ/mol\\\\\Delta H_{comb}=2043.85kJ/mol[/tex]

Answer: The concentration of [tex]H_2SO_4[/tex] is 0.234 M

Explanation:

According to the neutralization law,

[tex]n_1M_1V_1=n_2M_2V_2[/tex]

where,

[tex]n_1[/tex] = basicity [tex]H_2SO_4[/tex] = 2

[tex]M_1[/tex] = molarity of [tex]H_2SO_4[/tex] solution = ?

[tex]V_1[/tex] = volume of  [tex]H_2SO_4[/tex] solution = 50.0 ml

[tex]n_2[/tex] = acidity of [tex]NaOH[/tex] = 1

[tex]M_1[/tex] = molarity of [tex]NaOH[/tex] solution = 0.375 M

[tex]V_1[/tex] = volume of  [tex]NaOH[/tex] solution = 62.5 ml

Putting in the values we get:

[tex]2\times M_1\times 50.0=1\times 0.375\times 62.5[/tex]

[tex]M_1=0.234M[/tex]

Therefore concentration of [tex]H_2SO_4[/tex] is 0.234 M

Answer:

Water acts as a solvent of carbon dioxide excreted from tissues, in blood and helps in regulating pH (because it forms carbonic acid that lowers pH when it tends to get higher). Blood pH should be maintained at about 7.4. One major reason is that the structure of protein is dependent ton pH because pH determines its ionization hence also affecting the charges and interaction between side groups of amino acids. A change in pH may, therefore, denature proteins and negatively affect cellular functions.

Answer:

10.5 g

Explanation:

Step 1: Given data

Step 2: Calculate the moles of solute (n)

Molarity is equal to the moles of solute divided by the liters of solution.

M = n/V

n = M × V

n = 0.243 mol/L × 0.580 L = 0.141 mol

Step 3: Calculate the mass corresponding to 0.141 moles of KCl

The molar mass of KCl is 74.55 g/mol.

0.141 mol × 74.55 g/mol = 10.5 g

Answer:

[tex]\mathbf{-1.12 \times 10^4 \ kJ/mol}[/tex]

Explanation:

Given that:

mass (m) of the sample = 1.02 g

number of moles of stearic acid  [tex]=\dfrac{mass}{molar mass}[/tex]

[tex]= \dfrac{1.02 \ g}{284.49 \ g/mol} \\ \\ = 0.000358 \ moles[/tex]

The change in temp. [tex]\Delta T = 4.26^0 \ C[/tex]

heat capacity of the calorimeter (c) = 9.43 kJ/° C

Thus, heat due to reaction = cΔT

= 9.43 kJ/° C × 4.26° C

= 40.17 kJ

The heat in kJ/mol = [tex]\dfrac{40.17 \ kJ}{0.00358 \ mol}[/tex]

= 11204.23 kJ/mol

= 1.12 × 10⁴ kJ/mol

As a result of  the reaction is exothermic, the heat reaction of the  combustion is:

[tex]\mathbf{-1.12 \times 10^4 \ kJ/mol}[/tex]

Answer:

A) 2 Al(s) + 6 HCl(aq) → 2 AlCl₃(aq) + 3 H₂(g)

No, this is a single replacement reaction, in which Al replaces H in its acid.

B) 2 Al(s) + 3 Cl₂(g) → 2 AlCl₃(s)

No, this is a synthesis reaction, in which two simple substances combine to form a compound.

C) 2 AlCl₃(s) → 2 Al(s) + 3 Cl₂(g)

No, this is a decomposition reaction, in which a compound decomposes into simple substances.

D) AlCl₃(aq) + 3 KOH(aq) → Al(OH)₃(s) + 3 KCl(aq)​

Yes, this is a double replacement reaction, in which both reactants exchange their cations and anions.

Answer:

0.95 L

Explanation:

Step 1: Given data

Concentration of the Mg(NO₃)₂ solution (C): 0.32 M (0.32 mol/L)

Mass of Mg(NO₃)₂ (solute): 45 g

Step 2: Calculate the moles corresponding to 45 g of Mg(NO₃)₂

The molar mass of Mg(NO₃)₂ is 148.33 g/mol.

45 g Mg(NO₃)₂ × 1 mol Mg(NO₃)₂ /148.33 g Mg(NO₃)₂ = 0.303 mol Mg(NO₃)₂

Step 3: Calculate the volume of solution that contains 0.303 moles of Mg(NO₃)₂

The concentration of the solution is 0.32 M, that is, there are 0.32 moles of Mg(NO₃)₂ per liter of solution.

0.303 mol Mg(NO₃)₂ × 1 L Solution / 0.32 mol Mg(NO₃)₂ = 0.95 L

Explanation:

Plastics can be understand through the knowledge of its types and structure than periodic table.

Answer:

56.8 g

Explanation:

Your first conversion factor is the molar mass of H2O to convert from grams of water to moles. Your second conversion factor is the mole ratio of 2 mol C2H10 for every 10 mol H2O. Your last conversion factor is the molar mass of C2H10 to convert from moles back to grams.

150. g H2O • (1 mol H2O / 18.02 g H2O) • (2 mol C2H10 / 10 mol H2O) • (34.1 g C2H10 / 1 mol C2H10) = 56.8 g C2H10

Answer:

Change in temperature (Δt) = 18.18°C (Approx.)

Explanation:

Given:

Mass of metal block (M) = 55g

Specific heat of metal (c) = 0.45 J/g°C

Amount of energy added (Q) = 450 J

Find:

Change in temperature (Δt)

Computation:

Using Specific Heat Energy formula

Q = McΔt

450 = (55)(0.45)(Δt)

450 = (24.75)(Δt)

Change in temperature (Δt) = 450 / 24.75

Change in temperature (Δt) = 18.18°C (Approx.)

mass percent = (mass of element in 1 mole of compound / mass of 1 mole of compound) x 100. The formula for a solution is:

mass percent = (grams of solute / grams of solute plus solvent) x 100. or.

mass percent = (grams of solute / grams of solution) x 100. The final answer is given as %.
