Ionic compounds form when metals transfer valence electrons to nonmetals. Ionic compounds exist as crystals rather than molecules.

A water sample has a pH of 8.2 and a bicarbonate concentration of 97 mg/L. What is the alkalinity of the sample in moles/L and i
goldfiish [28.3K]

Answer:6.94

Explanation:

Molar mass of CaCO3=40+12+16×3

=40+12+48=100g/mol

Moles=mass of substance/molar mass

=97mg/100g=0.097/100=0.00097moles/L.

PH=-log[CaCo3]=-log(0.00097)=6.94

P.s it's log to base e

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.

Apply solubility rules of inorganic slats to predict the occurance of precipitation reactions?
kakasveta [241]

Explanation:

An ionic solution is when a compound's ions in an aqueous solution have dissociated. As you combine two aqueous solutions, a reaction occurs. This is when you find out whether or not a precipitate is going to form. A precipitate occurs when the ion reaction component in water is insoluble.The formation of a precipitate is an indication that a chemical change has occurred. for example if we mix clear solutions of silver nitrate and sodium chloride, sodium nitrate is formed which is a precipitate.
