Answer:
8.32 s⁻¹
Explanation:
Given that:
The concentration of myosin = 25 pmol/L
R_max = 208 pmol/L/s
The objective is to determine the turnover number of the enzyme molecule myosin, which has a single active site.
In a single active site of enzyme is known to be a region where there is binding of between substrate molecules, thereafter undergoing chemical reaction.
The turnover number of the enzyme is said to be the number of these substrate molecule which binds together are being converted into products.
The turnover number of the enzyme molecule of myosin can be calculated by the expression: 
⇒ 
= 8.32 s⁻¹
4Fe+3O₂⇒2Fe₂O₃
CO₂+2Cl₂⇒O₂+CCl₄

Equalization of chemical reactions can be done using variables. Steps in equalizing the reaction equation:
1. gives a coefficient on substances involved in the equation of reaction such as a, b, or c, etc.
2. make an equation based on the similarity of the number of atoms where the number of atoms = coefficient × index (subscript) between reactant and product
3. Select the coefficient of the substance with the most complex chemical formula equal to 1
For simple equations, you can experiment with the balance of the number of atoms on the left and right
4Fe+3O₂⇒2Fe₂O₃
CO₂+2Cl₂⇒O₂+CCl₄
aFe+bO₂⇒Fe₂O₃
Fe , left=a, right=2⇒a=2
O, left=2b, right=3⇒2b=3⇒b=3/2
the equation :
2Fe+3/2O₂⇒Fe₂O₃ x2
4Fe+3O₂⇒2Fe₂O₃
aCO₂+bCl₂⇒O₂+CCl₄
C, left=a, right=1⇒a=1
Cl, left=2b, right=4⇒b=2
O, left=2a, right=2⇒2a=2⇒a=1
the equation :
CO₂+2Cl₂⇒O₂+CCl₄

Answer:
D - Hydroxide Ion (OH-)
Explanation:
A base provides either hydroxide ions (OH–) or other negatively charged ions that combine with hydrogen ions, reducing their concentration in the solution and thereby raising the pH. In cases where the base releases hydroxide ions, these ions bind to free hydrogen ions, generating new water molecules.

Answer:
a) The approximate absorbance of benzoic acid at 228 nm? : A = 0.8
b) The molar absorptivity(∈)
of benzoic acid at 228 nm? : ∈ = 
Explanation:
Looking at the absorbance spectra, we can see that the approximate absorbance of benzoic acid at 228 is 0.8.
mass concentration of benzoic acid = 
the molar concentration of benzoic acid = (mass concentration of benzoic acid) / (molar mass of benzoic acid )
molar concentration of benzoic acid = 
molar concentration of benzoic acid = 
molar absorptivity (∈) of benzoic acid = (absorbance) /[ (molar concentration of benzoic acid ) × (path length) ]
∈ = (0.8) / [ (
) ×(1.00 cm)]
=
