The properties of elements are determined by their group/family. Usually, its the area they are located on the periodic table. The valence electrons also determine reactivity, etc.

Hello,
1. In this case, for the given p-V equation, one could use the two states to form a 2x2 linear system of equations in terms of A and B:


Whose solution by any method for solving 2x2 linear system of equations (elimination, reduction or substitution) is:

2. Now, for us to compute the work, we must first compute n, as the power relating the pressure and volume for this process:

Now, we compute the work:

Regards.
Answer:
Newton's laws are very important because they tie into almost everything we see in everyday life. These laws tell us exactly how things move or sit still, like why you don't float out of bed or fall through the floor of your house.
Explanation: Newton's laws of motion are important because they are the foundation of classical mechanics, one of the main branches of physics. Mechanics is the study of how objects move or do not move when forces act upon them.
Answer:
73.68 J
Explanation:
To find the energy absorbed by nickel, you need to use the following equation:
Q = mcΔT
In this equation,
-----> Q = energy (J)
-----> m = mass (g)
-----> c = specific heat (J/g°C)
-----> ΔT = change in temperature
The change in temperature is found by subtracting the initial temperature from the final temperature. You can plug the given values into the equation and simplify to find the energy absorbed.
m = 10.0 g
c = 0.120 J/g°C
ΔT = 63.4 °C - 2.0 °C = 61.4 °C
Q = mcΔT
Q = (10.0 g)(0.120 J/g°C)(61.4 °C)
Q = 73.68 J
