Answer:
do what you can do not what people tell you to do
Explanation:
Answer:
Equilibrium constant for the reaction is 0.0892
Explanation:
This is the reaction of equilibrium
H₂O + Cl₂O ⇄ 2HClO
Eq 0.077M 0.077M 0.023M
Let's make the expression for Kc
Kc = [HClO]² / [Cl₂O] . [H₂O]
Kc= 0.023² / 0.077 . 0.077 = 0.0892
Answer:
im pretty sure the correct option here id c

Answer:
C₁₁H₁₂NO₄
Explanation:
In order to determine the empirical formula of doxycycline, we need to follow a series of steps.
Step 1: Determine the centesimal composition
C: 59.5 mg/100 mg × 100% = 59.5%
H: 5.40 mg/100 mg × 100% = 5.40%
N: 6.30 mg/100 mg × 100% = 6.30%
O: 28.8 mg/100 mg × 100% = 28.8%
Step 2: Divide each percentage by the atomic mass of the element
C: 59.5 /12.0 = 4.96
H: 5.40/1.00 = 5.40
N: 6.30/14.0 = 0.450
O: 28.8/16.0 = 1.80
Step 3: Divide all the numbers by the smallest one
C: 4.96/0.450 = 11
H: 5.40/0.450 = 12
N: 0.450/0.450 = 1
O: 1.80/0.450 = 4
The empirical formula of doxycycline is C₁₁H₁₂NO₄
