Answers

Answer:

See explanation

Explanation:

In the section A,B

C triple bond O has a higher bond energy. A triple bond is shorter and more difficult to break hence they have a higher bond energy.

For the same reason in the C,D section; C triple bond N has a higher bond energy.

In the next section, the higher the bond order the shorter the bond. Hence C triple bond C is the shortest in the A,B section while C triple bond O is the shortest in the C,D section. Both have a bond order of 3.

In the A,B section; I is larger than Br hence H-Br has the shortest bond length.

In the C,D section; Br is larger than Cl hence P-Cl has the shortest bond length.

1. What volume, will be occupied by 3.86 g of C2H2 gas (acetylene) at 2.50 atm and a temperature
of 28.5 °C?
2. A gas at 650.0 torr and 75 °C is cooled to 25 °C. What is the pressure of the gas after it has
cooled?

Answers

Answer:

1. V = 1.47L

Explanation:

1) Using PV = nRT

Where;

P = pressure (atm)

V = volume (L)

R = gas constant (0.0821 Latmk mol)

n = number of moles

T = temperature (K)

To get number of moles, we say mole = mass/molar mass

Molar Mass of C2H2 = 12(2) + 1(2)

= 24 + 2 = 26g/mol

mole = 3.86/26

mole = 0.148mol

T (K) = 28.5°C + 273.15

T(K) = 301.65K

PV = nRT

2.5 × V = 0.148 × 0.0821 × 301.65

2.5V = 3.665

V = 3.665/2.5

V = 1.466

V = 1.47L

R =

PV = nRT

P1 V1\ n1 T1 =P2 V2/ n2 T2

1. What volume, will be occupied by 3.86 g of C2H2 gas (acetylene) at 2.50 atm and a temperature

of 28.5 °C?

2. A gas at 650.0 torr and 75 °C is cooled to 25 °C. What is the pressure of the gas after it has

Answer: D

Explanation:  Physical science is the study of the inorganic world. That is, it does not study living things. (Those are studied in biological, or life, science.) The four main branches of physical science are astronomy, physics, chemistry, and the Earth sciences, which include meteorology and geology.
