A generic Lewis structure is given where Y represents the central atom and the outer atoms are represented by X. The outer atoms

are not necessarily all the same element. The central Y atom has one lone pair of electrons. The Y atom is double bonded to an X atom with two lone pairs of electrons. The Y atom is also single bonded to an X atom with three lone pairs of electrons. Which compound is represented by the generic Lewis structure?

Answer:

Compound is the Nitrosyl Chloride; NOCl

Explanation:

From the Question, we have two X atoms (different elements) bonded to Y.

The central Y atom has one lone pair of electrons.

- A single lone pair can be found with atoms in the nitrogen group such as nitrogen in ammonia

The Y atom is double bonded to an X atom with two lone pairs of electrons.

- Two lone pairs can be found with atoms in the chalcogen group such as oxygen in water

The Y atom is also single bonded to an X atom with three lone pairs of electrons.

- The halogens can carry three lone pairs such as in hydrogen chloride.

Compound is the Nitrosyl Chloride; NOCl

To what temperature should 2.3L of a gas at 25degree Celsius be heated in order to expand its volume to 4 L under constant press
lakkis [162]

Answer:

518.52K

Explanation:

Charles law, which describes the direct relationship between the volume and the temperature of a gas when the pressure is constant, will be used for this question. The Charles law equation is:

V1/T1 = V2/T2

Where; V1 is the volume of the gas at an initial state (Litres)

T1 is the absolute temperature of the gas at an initial state (Kelvin)

V2 is the volume of the gas at a final state (Litres)

T2 is the absolute temperature of the gas at a final state (Kelvin)

According to the question, V1 = 2.3L, T1 = 25°C, V2 = 4L, T2 = ?

We need to convert the temperature to the absolute temperature unit in Kelvin (K) i.e.

T(K) = T(°C) + 273.15

T(K) = 25°C + 273.15

T1 (K) = 298.15K

To find for T2 in the equation, we make T2 the subject of the formula:

T2 = V2 × T1 / V1

T2 = 4 × 298.15 / 2.3

T2 = 1192.6/2.3

T2 = 518.52

Thus, the temperature must be heated to 518.52K in order to expand to a volume of 4L. This answer is in accordance to Charles law that the volume increases with increase in temperature and vice versa.

1) How many grams of carbon dioxide are produced at the same time as 360 g of water vapor in the
shutvik [7]

Answer:

3520 g of CO₂

Explanation:

2C₂H₆ + 70₂ → 4CO₂ + 6H₂O

molar ratio of the above reaction is;

2 : 7 → 4 : 6

2 moles of C₂H₆ will form 6 moles of H₂O

Thus, 1 mole of C₂H₆ will form 3 moles of H₂O

mass of H₂O = 360 g

molecular weight of H₂O = 18 g/mol

molar mass = mass ÷ molecular weight = 360÷18 = 20 moles

Total number of moles of H₂O formed = 6 * 20 moles = 120 moles

Number of moles of C₂H₆ reacted = 120 moles ÷ 3 = 40 moles

molar ratio of C₂H₆ to CO₂ = 1 : 2

Thus, number of moles of CO₂ formed = 2 * 40 moles = 80 moles

molecular weight of CO₂ = 44 g/mol

mass of CO₂ formed = number of moles x molecular weight = 80 * 44 = 3520 g
