Catalase is an enzyme that speeds up the breakdown of hydrogen peroxide in cells. During this reaction oxygen is given off. A sc
Softa [21]

Answer:

The correct option is A

Explanation:

An independent variable is <u>a variable that is intentionally altered (directly or indirectly) and is not dependent on another variable</u> in the course of an experiment. Unlike the independent variable, the dependent variable depends or is presumed to depend on the altered independent variables.

From the explanation above, it can be deduced that the concentration of the catalase is the independent variable as it was intentionally altered (by using different concentrations) in the course of the experiment. The amount of oxygen given off is the dependent variable here

Given the following data, determine the order of reaction with respect to H2.
alex41 [277]

Answer:

First-order with respect to hydrogen.

Explanation:

Hello!

In this case, considering that the rate law of this reaction can be expressed via:

r=k*p_{H_2}^m*p_{ICl}^n

If we want to know m, the order of reaction with respect to hydrogen, we need to relate the experiments 1 and 3 in order to get rid of the pressure of ICl:

\frac{r_1}{r_3} =\frac{k*p_{H_2,1}^m*p_{ICl,1}^n}{k*p_{H_2,3}^m*p_{ICl,3}^n}

Thus, we plug in the given rates, and pressures to get:

\frac{1.34}{0.266} =\frac{k*250^m*325^n}{k*50^m*325^n}

So we can cancel wout k and 325^n:

\frac{1.34}{0.266} =\frac{250^m}{50^m}

Next we solve for m, the order of reaction with respect to hydrogen:

5.04 =5^m\\\\log(5.04)=m*log(5)\\\\m=\frac{log(5.04)}{log(5)} \\\\m=1.0

It means it is first-order with respect to hydrogen.

Regards!

Which type of chemical reaction occurs in Ca + Cl2 mc009-1.jpg CaCl2?
gregori [183]

Answer : The correct option is, (a) Synthesis

Explanation :

Synthesis reaction : A chemical reaction where multiple substances or reactants combine to form a single product.

It is represented as,

X+Y\rightarrow XY

Combustion reaction : A chemical reaction in which a hydrocarbon react with the oxygen to give product as carbon dioxide and water.

It is represented as,

CH_4+2O_2\rightarrow CO_2+2H_2O

Single replacement reaction : A chemical reaction in which the more reactive element replace the less reactive element.

It is represented as,

A+BC\rightarrow AC+B

In this reaction, A is more reactive element and B is less reactive element.

Double replacement reaction : It is a type of chemical reaction where a positive cation and a negative anion of two reactants exchange places to form two new products.

It is represented as,

XY+AB\rightarrow XB+AY

(X and A are the cations, Y and B are the anions)

The given reaction is, Ca+Cl_2\rightarrow CaCl_2

In this reaction, calcium combine with the chloride to form calcium chloride as a product.

Hence, the given type of reaction is a synthesis reaction.

What two categories of chemicals are based on carbon content?
zaharov [31]

Answer: Option (D) is the correct answer.

Explanation:

Inorganic compounds are the compounds which lack carbon atoms.

For example, water (H_{2}O) is an inorganic compound.

Whereas organic compounds are the compounds which have carbon atom(s). For example, methane (CH_{4}) is an organic compound.

On the other hand, molecules, compounds, living, non-living, ionic, and covalent categories of chemicals can either have carbon content or not have carbon content.

Thus, we can conclude that inorganic and organic categories of chemicals are based on carbon content.
