Answer : The final volume of gas will be, ![2.36\times 10^9L](https://tex.z-dn.net/?f=2.36%5Ctimes%2010%5E9L)
Explanation :
Charles' Law : It is defined as the volume of gas is directly proportional to the temperature of the gas at constant pressure and number of moles.
![V\propto T](https://tex.z-dn.net/?f=V%5Cpropto%20T)
or,
![\frac{V_1}{V_2}=\frac{T_1}{T_2}](https://tex.z-dn.net/?f=%5Cfrac%7BV_1%7D%7BV_2%7D%3D%5Cfrac%7BT_1%7D%7BT_2%7D)
where,
= initial volume of gas = ![2.74\times 10^9L](https://tex.z-dn.net/?f=2.74%5Ctimes%2010%5E9L)
= final volume of gas = ?
= initial temperature of gas = ![20.0^oC=273+20.0=293K](https://tex.z-dn.net/?f=20.0%5EoC%3D273%2B20.0%3D293K)
= final temperature of gas = ![-20.0^oC=273+(-20.0)=253K](https://tex.z-dn.net/?f=-20.0%5EoC%3D273%2B%28-20.0%29%3D253K)
Now put all the given values in the above formula, we get the final volume of the gas.
![\frac{2.74\times 10^9L}{V_2}=\frac{293K}{253K}](https://tex.z-dn.net/?f=%5Cfrac%7B2.74%5Ctimes%2010%5E9L%7D%7BV_2%7D%3D%5Cfrac%7B293K%7D%7B253K%7D)
![V_2=2.36\times 10^9L](https://tex.z-dn.net/?f=V_2%3D2.36%5Ctimes%2010%5E9L)
Therefore, the final volume of gas will be, ![2.36\times 10^9L](https://tex.z-dn.net/?f=2.36%5Ctimes%2010%5E9L)
When a material is heated, the kinetic energy of that material increases and its atoms and molecules move about more. This means that each atom will take up more space due to its movement so the material will expand. ... Some metals expand more than others due to differences in the forces between the atoms / molecules.
In these atoms, the positive and negative charges cancel each other out, leading to an atom with no net charge.
(Protons, neutrons, and electrons)
An ion is an atom with a different number of electrons than its number of proton, the charge of an ion is not net
need more information to find the charge but it can't be 0 if it is an ion
an ionic bond is when 2 or more ions attract negative and positive
Answer:
Explanation:
iron is element number 26 this means that it has 26 number of electron and proton in its atomic structure so its atomic number is 26
