Answer:
Because a glass window is harder than a fingernail, a glass window would have a higher number on Mohs hardness scale
Explanation:
Answer:
The equillibrium constant Kc = 11.2233
Explanation:
Step 1:
aA + bB ⇔ cC + dD
with a, b, c and d = coefficients
Kc = equillibrium constant =( [C]^c [D]^d ) / ( [A]^a [B]^b)
Concentration at time t
[A] = 0.300 M
[B] =1.10 M
[C] = 0.450 M
Change :
A: -x
B: -2x
C: -x
The following reaction occurs and equillibrium is established
A + 2B ⇔ C
[A] = 0.110M
[B] = ?
[C] = 0.640 M
For A we see that after change: 0.3 -x = 0.11
Then for B we have 1.1 - 2x = ? ⇒ 1.1 -2 *0.19 = 0.72
This gives us for the equillibrium constant Kc = [C] / [A][B] ²
Kc = 0.64 / (0.11) * (0.72)² = 11.2233
Answer:
The noble gases have 8 valence electrons in their outermost electron shell. In other words, they have full out shells. These elements are highly stable.
Answer:
Co2,so2
Explanation:
Hybridization is the mixing of atomic orbitals to form new hybrid orbitals.
Molecule shapes arise from how many hybrid orbitals the central atom uses and how they are arranged.
