<span>What caused the bubbles to form when you added the catalyses to the hydrogen peroxide and water mixture at 40 °C? A. Catalyses activity heated the solution to its boiling point. B. Hydrogen gas formed during the formation of hydrogen peroxide. C. Oxygen gas formed during the decomposition of hydrogen peroxide.

This would be the water, mixture.</span>

\boxed{{\text{Formation of oxygen}}} caused the bubbles to form when catalase is added to the hydrogen peroxide and water mixture at 40\;^\circ {\text{C}}.

Further explanation:

Catalyst:

These are the substances that change the rate of a chemical reaction but these don’t get consumed in the reaction. These have wide applications in petroleum, fertilizer and pharmaceutical industries. These are also used in the formation of many substances such as ammonia, nitric acid, and sulphuric acid.

Enzymes are biological catalysts that increase the rate of chemical reactions. These are highly specific in nature. Most enzymes are proteins. These increase the rate of reaction by decreasing the activation energy. Catalase is a common enzyme that catalyzes the decomposition of hydrogen peroxide to water and oxygen.

The given reaction occurs as follows:

2{{\text{H}}_{\text{2}}}{{\text{O}}_{\text{2}}}\xrightarrow{{{\text{Catalase}}}}2{{\text{H}}_{\text{2}}}{\text{O}} + {{\text{O}}_{\text{2}}}

Here, catalase catalyzes the decomposition of hydrogen peroxide and result in the formation of water and oxygen. Bubbles are formed due to production of oxygen gas during the reaction.

Hypochlorous acid decays in the presence of ultraviolet radiation. Assume that degradation occurs accord- ing to first-order kin
Dennis_Churaev [7]

Answer:

35.75 days

Explanation:

From the given information:

For first-order kinetics, the rate law can be expressed as:

\mathsf{In \dfrac{C}{C_o} = -kt}

Given that:

the rate degradation constant = 0.12 / day

current concentration C = 0.05 mg/L

initial concentration C₀ = 3.65 mg/L

\mathsf{In( \dfrac{0.05}{3.65})= -(0.12) t}

㏑(0.01369863014) = -(0.12) t

-4.29 = -(0.12)

t = -4.29/-0.12

t = 35.75 days

Consider the work of Thomson, Rutherford, and Bohr. In your opinion, which was the most important and why? Be sure to state what
kobusy [5.1K]
The two of them both made models of the current atom, which was very excellent because now we could imagine how an atom would look.  I would say that the best one was the electron orbital configuration because we needed to know what valence electrons are.

Why does the solution decolorize on standing after the equivalence point has been reached?
Arisa [49]

The equivalence point of a titration is equal to its stoichiometric equivalents of analyte and titrant.

Depending on the concentration of titrant we could be adding little excess of it and this may result in persistence of color of solution. After continuous stirring for a while the excess titrant may react with dissolved CO₂ in air and thus decolorizing the solution.

If you burn 23.4 g of hydrogen and produce 209 g of water, how much oxygen reacted?
Kitty [74]
The chemical reaction is expressed as:

2H2 + O2 = 2H2O

To determine the amount of oxygen used in the reaction, we use the amount of water produced and the relation of the substances in the reaction we do as follows:

209 g H2O ( 1 mol / 18.02 g ) ( 1 mol O2  / 2 mol H2O ) ( 32 g / 1 mol ) = 185.57 g O2
