D = m / V
13.6 = 8.3 / V
V = 8.3 / 13.6
V = 0.610 mL
hope this helps!
Answer:
Explanation:
[ so₃] = 4.37 x 10⁻²
[so₂] = 4.77 x 10⁻²
[ o₂] = 4.55 x 10⁻²
Qc = (4.37)²x10⁻⁴ /(4.77)².(4.55) x 10⁻⁶ =18.44
Qc is less than Kc hence in order to reach equilibrium more of so₃ will be produced . Statement 1 is true.
Kc is always constant . Statement 2 is false.
Statement 3 is false because statement 1 is true.
Qc Is smaller than Kc . So statement 4 is false.
The reaction is not in equilibrium. Statement 5 is false.
Answer:
Lewis structure for isomers of butane has been given below.
Explanation:
Butane is a saturated alkane with molecular formula 
. Due to different positing of methyl groups, positional isomerism exists in butane.
Butane has two positional isomers with same molecular formula. One is n-butane and another one is isobutane. Lewis structures of these two isomers have been given below.
The correct answer is B. Compounds put together will form mixtures because compounds itself are pure substances which contains elements and atoms. Mixtures is a system that is made up of two or more substances or compounds which are not combined chemically.
