Answer:
high concentrations of molecular is to a lower concentration of monoculars
Silicon and Germanium. You can conclude it from its position in the periodic table. Silicon and Germanium are in the same group of the Carbon. That implies that all three have the same number of electrons in the outer orbital, which is responsible for the bonds.
1. You can use the formula V1/ T1 = V2/T2
Solve for V2 give than V1= 10.0 L, T1= 25 C= 298 K, T2= 10 C= 283 K.
(10.0L/298K)= V2/283K------> V2= 9.50 L.
I cant see the answer there.. weird!
2. you can use the formula P1V1= P2V2
solve for V2 given than P1= atm, V1= 2.0 L, P2= 300 atm.
(1atm)x(2.0L)= (300atm)V2----->0.00667 atm.
so answer is A.
