Ammonia is a base. One adding ammonia to water,the resulting solution will become basic. pH of an alkaline solution is 7. So the pH will increase
Fructose is an Organic molecule among the given options.
Organic Molecules :
An organic molecule is one which contains carbon, although not all compounds that contain carbon are organic molecules. Noticeable exceptions are carbon monoxide (CO), carbon dioxide (CO2), carbonates (e.g. calcium carbonate), carbides (e.g. calcium carbide) and cyanides (e.g. sodium cyanide). Pure carbon compounds such as diamond and graphite are also not organic compounds. Organic molecules can range in size from simple molecules to complex structures containing thousands of atoms.
Although carbon is present in all organic compounds, other elements such as hydrogen (H), oxygen(O), nitrogen (N), sulfur (S) and phosphorus (P) are also common in these molecules.
In simple, Molecules needed for life that have carbon are called Organic Molecules.
The molar mass of H2O can be calculated as the following.
M(H2O)= [2 x M(H)] + [M(O)].
And we know that M(H) = 1g/mol, M(O) = 16g/mol.
So, M(H2O)= 2x1 + 16 = 18g/mol,
That means 1 mole of H2O contains 18g.
Hence, one mole of H2O corresponds to 18 grams.
A pure substance can be defined as any single type of material that has not been contaminated by another substance. In chemistry, a pure substance has a definite composition. It can be a compound or an element. A pure substance is considered to be a material that consists of one type of "building block" of matter.
Examples of pure substances include tin, sulfur, diamond, water, pure sugar (sucrose), table salt (sodium chloride) and baking soda (sodium bicarbonate).
Tin, sulfur, and diamond are examples of pure substances which are chemical elements. All elements are pure substances.
Water, sugar, salt and baking soda are pure substances which are chemical compounds. Chemical compounds also are pure substances
Chemical weathering is what happens when rocks are broken down and chemically altered.
Chemical weathering is the breakdown of rocks by chemical reactions. Chemical weathering involves changes in the chemical composition of the existing rock to form new rock. Some examples of chemical weathering are hydrolysis, oxidation, carbonation, dissolution, etc.
