Chemistry

Veronika [31]3 years ago

Given the balanced chemical equation for combustion of propane:

C_{3}H_{8}+5O_{2}-->3CO_{2}+4H_{2}O

Moles of propane C_{3}H_{8}=3.6 mol

Propane is the limiting reactant as the other reactant oxygen is said to be present in excess.

Amount of products formed would depend on the moles of limiting reactant.

Mole ratio of water to propane as per the balanced chemical equation

                                   =\frac{4molH_{2}O }{1molC_{3}H_{8}}

Calculating the moles of water produced from 3.6 mol propane:

  3.6molC_{3}H_{8}*\frac{4molH_{2}O }{1molC_{3}H_{8}}

                          = 14.4molH_{2}O

Theoretical yield of water = 14.4 mol

Actual yield = 12 mol

Percent yield = \frac{ActualYield}{TheoreticalYield}*100

                      = \frac{12 mol}{14.4 mol}*100=83.3%

Determine the chemical formulas for the two compounds below. (Carbon, Hydrogen, and Oxygen).
tester [92]
Remember that any intersection of lines is a C, and that the number of hydrogens attached are the necessary to complet the 4 bonds.

1) CH3 - CH (OH) - CH (CH3) -CH3

2) CH3 - O - CH(CH3)-CH2 - CH3

I have used the parenthesis to indicate that the radical inside is in other branch, bonded by a single line -

The job outlook for physical therapists
Ann [662]

The job outlook for physical therapists<u>  "will improve over time".</u>


Physical therapists, help harmed or sick individuals enhance their development and deal with their agony. These therapists are frequently an imperative piece of the restoration, treatment, and counteractive action of patients with unending conditions, ailments, or wounds.  

Physical therapists commonly work in private workplaces and centers, clinics, patients' homes, and nursing homes. They invest quite a bit of their energy in their feet, effectively working with patients.

Calculate the enthalpy of the reaction below (∆Hrxn, in kJ) using the bond energies provided. CO(g) + Cl₂(g) → Cl₂CO(g).
nalin [4]

The enthalpy change of the reaction below (ΔHr×n , in kJ) using the bond energies provided. CO(g) + Cl₂(g) → Cl₂CO(g). is - 108kJ.

The bond energies data is given as follows:

BE  for C≡O  = 1072 kJ/mol

BE for Cl-Cl = 242 kJ/mol

BE for C-Cl = 328 kJ/mol

BE for C=O = 766 kJ/mol

The enthalpy change for the reaction is given as :

ΔHr×n = ∑H reactant bond - ∑H product bond

ΔHr×n = ( BE C≡O + BE Cl-Cl) - ( BE C=O + BE 2 × Cl-Cl )

ΔHr×n = ( 1072 + 242 ) - ( 766 + 656 )

ΔHr×n = 1314 - 1422

ΔHr×n = - 108 kJ

Thus, The enthalpy change of the reaction below ( ΔHr×n , in kJ) using the bond energies provided. CO(g) + Cl₂(g) → Cl₂CO(g). is - 108kJ.
