Answer:

Explanation:

The two carbon atoms would be different. These different carbon isotopes are called isotopes. Isotopy is the existence of two or more atoms of the same element having the same atomic number but different mass number due to the difference in the number of neutrons in their various nuclei.

Carbon for example has 3 known isotopes which are:

                    ¹²₆C         ¹³₆C         ¹⁴₆C

These isotopes have different places in nature where they can be found. Some can occur together naturally.

Isotopes have the same chemical properties because they share similar electronic configuration.

A sample of helium gas occupies 355ml at 23°c. if the container the he is in is expanded to 1.50 l at constant pressure, what is
ss7ja [257]

Answer: The final temperature would be 1250.7 K.

Explanation: We are given a sample of helium gas, the initial conditions are:

V_{initial}=355mL=0.355L  (Conversion factor: 1L = 1000 mL)

T_{initial}=23\°C=296K (Conversion Factor: 1° C = 273 K)

The same gas is expanded at constant pressure, so the final conditions are:

V_{initial}=1.50L

T_{initial}=?K

To calculate the final temperature, we use Charles law, which states that the volume of the gas is directly proportional to the temperature at constant pressure.

V\propto T

\frac{V_{initial}}{T_{initial}}=\frac{V_{final}}{T_{final}}

Putting the values, in above equation, we get:

\frac{0.355L}{296K}=\frac{1.50L}{T_{final}}

T_f=1250.7K
