Fill in the missing piece of the table​
djyliett [7]

Answer: The final volume V_2 is 263.09 ml

Explanation:

To calculate the final volume of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

\frac{V_1}{T_1}=\frac{V_2}{T_2}

where,

V_1\text{ and }T_1 are the initial volume and temperature of the gas.

V_2\text{ and }T_2 are the final volume and temperature of the gas.

We are given:

V_1=156ml\\T_1=215^oC=(215+273)K=488K\\V_2=?\\T_2=550^0C=(550+273)K=823K

Putting values in above equation, we get:

\frac{156}{488}=\frac{V_2}{823}\\\\V_2=263.09ml

Thus final volume V_2 is 263.09 ml

Why do cars tires need more air in the winter then in the summer?

Aluminum has the electronic configuration 2,8,3. How many valence
Klio2033 [76]

Answer:

3 valence electrons

Explanation:

Because aluminum has three, that means three fluorines can bond. The make the formula AlF3, also known as aluminum trifluoride. Each of the fluorine atoms gets an electron to fill their shell, and the aluminum loses three, giving it a filled shell too (remember, aluminum has three extra electrons).
