Answer:

Compound is made of two or more than two elements in a fix ratio by mass. Compounds have different properties from the parent elements.

Explanation:

The chemical and physical properties of compound are different from the parent materials because it is produced from the chemical combination of elements. In chemical combination, bonds are formed and new substance is produced which is quite different from the parent substances. For example, CO2 is produced when carbon and oxygen react with each other. The properties of CO2 are different from carbon and oxygen.

Answer: A compound

Explanation: A compound is a substance which contains two or elements chemically combined together.

The properties of a compound are different from the properties of the individual elements. For example, water H2O which is made up of hydrogen and oxygen atoms has properties different from the individual properties of hydrogen and oxygen.

Also, water is a compound made up of hydrogen and oxygen atoms which are combined in the ratio is 2 hydrogen atoms to 1 oxygen atom.

Answer : The value of $K_c$ for the given reaction is, 0.36

Explanation :

Equilibrium constant : It is defined as the equilibrium constant. It is defined as the ratio of concentration of products to the concentration of reactants.

The equilibrium expression for the reaction is determined by multiplying the concentrations of products and divided by the concentrations of the reactants and each concentration is raised to the power that is equal to the coefficient in the balanced reaction.

As we know that the concentrations of pure solids and liquids are constant that is they do not change. Thus, they are not included in the equilibrium expression.

The given equilibrium reaction is,

$Br_2(aq)+Cl_2(aq)\rightleftharpoons 2BrCl(aq)$

The expression of $K_c$ will be,

$K_c=\frac{[BrCl]^2}{[Br_2][Cl_2]}$

First we have to calculate the concentration of $Br_2,Cl_2\text{ and }BrCl$ .

$\text{Concentration of }Br_2=\frac{Moles}{Volume}=\frac{0.500mol}{0.500L}=1M$

$\text{Concentration of }Cl_2=\frac{Moles}{Volume}=\frac{0.500mol}{0.500L}=1M$

$\text{Concentration of }BrCl=\frac{Moles}{Volume}=\frac{0.300mol}{0.500L}=0.6M$

Now we have to calculate the value of $K_c$ for the given reaction.

$K_c=\frac{[BrCl]^2}{[Br_2][Cl_2]}$

$K_c=\frac{(0.6)^2}{(1)\times (1)}$

$K_c=0.36$

Therefore, the value of $K_c$ for the given reaction is, 0.36

What do acids feel like

djverab [1.8K]

Answer:

In fact, some strong bases can burn the skin as badly as strong acids. Bases feel soapy or slippery because they react with acidic molecules in your skin called fatty acids. ... Like acids, bases change the colors of acid-base indicators, but the colors they produce are different. Bases turn litmus paper blue.
