Answer:
The reaction rate k is 0.0012563 (1/hour).
Explanation:
We considered the reactions occurring in the plant as first order, and represented by this equation:
where y is the BOD at time t, L is the initial value of BOD and k is the reaction rate.
If we replaced with the values
y = 2 mg O2/l (1% of the initial value)
L = 200 mg 02/l
t = 8 hr
We can calculate k
The reaction rate k is 0.0012563 1/hour.
<em><u>Given</u></em>
Weight of pottasium fluoride (KF) = 29 gms
<em><u>To find</u></em>
Number of moles of pottasium fluoride = ?
<em><u>Solution</u></em>
we know that molar mass of KF = 58.0967 g
Now,
<em>Number of moles = 29/58 = 0.5 moles</em>

Answer: faster than , less energy
Answer:
ionize
Explanation:
Acids are chemical substances that lose/donate their hydrogen ion (H+) when they react with water. This property of acids is termed IONIZATION. In a chemical reaction involving acids and bases, acids release their proton or hydrogen ion (H+) in the presence of water solutions to form a conjugate base, which is usually an anion.
For example, in the chemical reaction;
HX + H20 -------> X- + H30+
HX is the acid because it loses its electron to water and forms the anion, X-, which is the conjugate base. Hence, it can be said that acid HX ionizes in water.
