Answer:
How you going to delete my answer even though it was right but dont delete his answer bro didnt even say nun
Explanation:
Answer D
Thermal energy flows from the flask on the left to the flask on the right as energy is transferred from higher to lower temperature.
What is thermal energy?
Thermal energy is defined as a type of energy which is contained within a system which is responsible for temperature rise.Heat is a type of thermal energy.It is concerned with the first law of thermodynamics.
Thermal energy arises from friction and drag.It includes the internal energy or enthalpy of a body of matter and radiation.It is related to internal energy and heat .It arises when a substance whose molecules or atoms are vibrating faster.
These vibrating molecules and atoms collide and as a result of which heat is generated in a substance , more the collision of particles , higher is the thermal energy.

g A radioactive isotope of mercury, 197Hg, decays to gold, 197Au, with a disintegration constant of 0.0108hrs.-1. What % of the sample of mercury will remain after 10 days
Answers
Answer:
7.49% of Mercury
Explanation:
Let N₀ represent the original amount.
Let N represent the amount after 10 days.
From the question given above, the following data were obtained:
Rate of disintegration (K) = 0.0108 h¯¹
Time (t) = 10 days
Percentage of Mercury remaining =?
Next, we shall convert 10 days to hours. This can be obtained as follow:
1 day = 24 h
Therefore,
10 days = 10 day × 24 h / 1 day
10 days = 240 h
Thus, 10 days is equivalent to 240 h.
Finally, we shall determine the percentage of Mercury remaining as follow:
Rate of disintegration (K) = 0.0108 h¯¹
Time (t) = 10 days
Percentage of Mercury remaining =?
Log (N₀/N) = kt /2.303
Log (N₀/N) = 0.0108 × 240 /2.303
Log (N₀/N) = 2.592 / 2.303
Log (N₀/N) = 1.1255
Take the anti log of 1.1255
N₀/N = anti log 1.1255
N₀/N = 13.3506
Invert the above expression
N/N₀ = 1/13.3506
N/N₀ = 0.0749
Multiply by 100 to express in percent.
N/N₀ = 0.0749 × 100
N/N₀ = 7.49%
Thus, 7.49% of Mercury will be remaining after 10 days

Which statement is correct? (5 points)
The gas particles in both containers have the same average kinetic energy because they have equal number of particles
The gas particles in both containers have the same average kinetic energy because they have the same volume
The average kinetic energy of the gas particles is greater in container A because it has a lower temperature
The average kinetic energy of the gas particles is greater in container 8 because its particles move faster

Answers
Answer:
D. The average kinetic energy of the gas particles is greater in container B because its particles move faster.
Explanation:
Option D is the correct statement. From the excerpt, it can be seen that container B is being heated. The heat that is applied to container B will make the temperature of the gas to increase, thereby increasing the average kinetic energy. This will cause the gas molecules to mover faster and with force hitting the walls of the gas container. At this time, pressure should increase. Also, the volume of the gas increases just as the temperature of the gas also increases.
Answer:
D. The average kinetic energy of the gas particles is greater in container B because its particles move faster.

What kind of chemical bond forms when electrons are given away or taken on?
Answers
Answer:
ionic bonding
Explanation:
In ionic bonding, electrons are completely transferred from one atom to another. In the process of either losing or gaining negatively charged electrons, the reacting atoms form ions. The oppositely charged ions are attracted to each other by electrostatic forces, which are the basis of the ionic bond.
