Water, lower, and I'm not too sure for the third one... sorry.
Answer:
There are 19 atom sin total in antimony silicate,
.
Explanation:
Number of antimony atoms = 4 × 1 = 4
Number of silicon atoms = 3 × 1 = 3
Number of oxygen atoms = 3 × 4 = 12
Number of atoms in antimony silicate:
= 4 + 3 + 12 = 19
There are 19 atom sin total in antimony silicate,
.
If temperature were to double the pressure would likewise double. Increased temperature would increase the energy of the molecules and the number of collisions would also increase causing the increase in pressure.
I believe it’s the last option
