Answer:-
5.554 litres
Explanation:-
Initial Volume V 1 = 5.00 litres
Initial temperature T 1 = 34 C + 273 = 307 K
Final temperature T 2 = 68 C + 273 = 341 K
Using the relation of Charles Law (V 1 / T 1) = (V 2 / T 2)
New Volume V 2 = V1 x T2 / T1
Plugging in the values
V2 = 5.00 litres x 341 K / 307 K
= 5.554 litres.
4.61*10^22 oxygen atoms in 2.30 quartz
Answer:
A.
Explanation:
We know quite well that there are three states of matter. Solid,liquid and gaseous states.
While the gaseous states gives the highest freedom of movement, the solid state gives the least freedom of movement. Molecules and atoms of a solid are so tightly packed.
This makes them very dense as they are held together by strong intermolecular forces of attraction. These strong forces prevents the movement of the particles.
As these particles are strongly attracted towards each other, they tend to be incompressible.
It has 4 valence electron, all of which are needed to bond with nearest neighbors
