Chlorine is element number 17, so the electron configuration must be:
2,8,7
Answer:
In cold water, the food coloring diffuses (spreads out) through the water slowly. The hot water causes the food coloring to diffuse faster.
Explanation:
Answer:
Lithium fluoride i think but I am not really sure
But it should be Lithium fluoride
Explanation: that's because neighter boron nor nitrogen contains water
Answer:
electrons on the the outer most shell of an element
The total amount of gas present in the container of 1 L is 0.0446 moles and in container of 3 L is 0.1334 moles.
Explanation:
It is known that 1 mole of any gaseous element contains 22.4 litres of that gas molecules. So in order to determine the total amount of gas present in 1 L and 3 L, we can divide the given volume with the reciprocal of 22.4 litre to determine the moles of gas at 1 L and 3 L respectively.
So for 1 L

So no. of moles in 1 L = 0.0446 moles of that gas is present in 1 L volume.
Similarly, total amount of gas present in 3 L is
No. of moles present in 3 L = 
So, the total amount of gas present in 1 L is 0.0446 moles and in 3 L is 0.1334 moles. Thus, it can be stated that the number of moles increases with increase in the volume or on expansion of gas molecules.
