Which of the following bonds will have the smallest difference in electronegativity?
Vitek1552 [10]

Answer:

The answer to your question is the first choice (H₂)

Explanation:

Process

Look for the electronegativity of the elements of this exercise

a) H₂ = 2.2 - 2.2 = 0

b) NaF = 3.98 - 0.93 = 3.05

c) HBr = 2.96 - 2.2 = 0.76

d) HS⁻ = 2.58 - 2.2 = 0.38

The molecule that has the smallest difference in electronegativity is H₂

Two samples of matter differ in temperature by 20°C. What is the difference in temperature of these two samples using the Kelvin
anyanavicka [17]

Answer:

The difference is 293.15 Kelvin.

Explanation:

Given data:

Temperature difference of matter = 20°C

Temperature difference of matter in kelvin = ?

Solution;

Formula:

0°C +273.15

now we will put the values instead of 0.

20°C + 273.15 = 293.15 K

Thus, the temperature difference between two sample is 293.15 K.

A gas bottle contains 8. 61×1023 oxygen molecules at a temperature of 359. 0 k. what is the thermal energy of the gas? (you migh
Cloud [144]

A gas bottle contains 8. 61×1023 oxygen molecules at a temperature of 359. 0 k then the thermal energy of the gas is 6.35KJ.

<h3>What is thermal energy? </h3>

Thermal energy is the energy contained within a system which is responsible for its temperature. Heat is also termed as flow of thermal energy.

Thermal energy is directly proportional to the temperature. As temperature increase thermal energy increases.

Given,

temperature = 395K

Number of oxygen molecules= 8.61 × 10^(23)

Firstly we will calculate the number of moles = N/A

where A is the avagadro number = 6.022 × 10^(23)

number of moles = 8.61 × 10^(23)/6.022 ×10^(23)

number of moles = 1.42moles

Using the energy equation,

E = 3/2 × nRT

where R is the gas constant = 8.314J/molK

E = 3/2 × 1.42 × 8.314 × 359

= 6357.4J

= 6.35KJ

Thus, we found that the thermal energy of the gas is 6.35KJ.
