What is a nonpolar bond? ​

Answers

Answer 1

Answer:

Nonpolar covalent bonds are a type of bond that occurs when two atoms share a pair of electrons with each other. These shared electrons glue two or more atoms together to form a molecul

how much energy is required to change 110 grams of steam at 181 C to 40 C

Answers

Answer:

Q = -64893.84 J

Explanation:

Given data:

Mass of steam = 110 g

Initial temperature = 181 °C

Final temperature = 40°C

Energy released = ?

Solution:

Energy will released in this process because temperature is going to be decreased.

Specific heat capacity of water is 4.184 J/g.°C

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

ΔT = 40°C - 181 °C

ΔT = -141°C

Q =  110 g × 4.184 J/g.°C × -141°C

Q = -64893.84 J

Write the information obtained from solubility curves.​

Answers

Explanation:

The solubility curve helps us to compare the solubility of difference substances at same temperature. It gives the idea that solubility changes with the temperature. The solubility curve helps us to predict which substance will crystalize out first from hot solution containing two or more solutes.

21. Why are radioactive nuclei unstable?
a. There is not the proper neutron to proton ratio resulting in a stable nucleus
b. There is too much energy stored in the bonds between atoms
C. They need to gain/lose electrons to have a full valence energy level
d. Protons reverse their charges and begin to repel one another

Answers

Answer:

a. There is not the proper neutron to proton ratio resulting in a stable nucleus

Explanation:

Radioactive nuclei are unstable because they do not have a proper neutron to proton ration that can result in a stable nucleus for them.

Every atomic nucleus has specific neutron to proton ratio. The ratio ensures the stability of the nucleus. Any nucleus with a neutron/proton combination different from its stability ratio will be unstable and split into one or more other nuclei. This is usually with an attendant emission of small particles of matter and electromagnetic ionizing radiation and energy.
