Answer:

D. Catalase is an enzyme, O₂ and H₂O are products, and H₂O₂ is a substrate.

Explanation:

As per the given reaction the compound (H₂O₂) on the left side of the equation is the reactant or substrate and the two compounds (O₂ and H₂O₂ )on the right side is the product. Catalase is neither a reactant nor product, it is a catalyst. The role of a catalyst is to accelerate the rate of a reaction by lowering the activation energy of the reaction without itself undergoing any change.

Calculate the percent ionization of propionic acid (C2H5COOH) in solutions of each of the following concentrations (Ka is given

tekilochka [14]

Answer:

a) = 0.704%

b) = 1.30%

c) = 2.60%

Explanation:

Given that:

$K_a$ = $1.34*10^{-5$

For Part A; where Concentration of A = 0.270 M

Percentage Ionization(∝) $\alpha = \sqrt{\frac{K_a}{C} }$

$\alpha = \sqrt{\frac{1.34*10^{-5}}{0.270} }$

$\alpha = \sqrt{4.9629*10^{-5}}$

$\alpha = 7.044*10^{-3$

percentage% (∝) = $7.044*10^{-3}*100$

= 0.704%

For Part B; where Concentration of B = $7.84*10^{-2$ M

$\alpha = \sqrt{\frac{1.34*10^{-5}}{7.84*10^{-2}} }$

$\alpha = \sqrt{1.709*10^{-4} }$

$\alpha = 0.0130\\$

percentage% (∝) = 0.0130 × 100%

= 1.30%

For Part C; where Concentration of C= $1.92*10^{-2} M$

$\alpha = \sqrt{\frac{1.34*10^{-5}}{1.97*10^{-2}} }$

$\alpha = \sqrt{6.802*10^{-4}}$

$\alpha =0.02608$

percentage% (∝) = 0.02608 × 100%

= 2.60%

Answer:

HCl is the formula for Hydrochloric acid

Explanation:

Chemical formula is a formula of a compound showing the symbols of elements present in the compound.
Chemical formula also shows the number of atoms of each element present in a compound.
HCl is the chemical formula of hydrochloric acid. From this formula we can tell that hydrochloric acid is made up of hydrogen and chlorine elements.
The formula also shows that HCl contains 1 hydrogen atom and 1 chlorine atom.
