The chemical formula of Nylon is (C12H22N2O2)n

When table sugar (sucrose) is dehydrated with concentrated sulfuric acid (H2SO4), the sugar turns into a column of carbon, and water and carbon dioxide are produced. This is a dehydration reaction, which is a chemical reaction that removes water from a molecule or ion.

Drinking hard water can help strengthen bones because it contains calcium, an essential mineral for bone health. Your body absorbs calcium from hard water the same way it does from other food sources.

Simple sugar molecules (monosaccharide ) when combined to form larger molecules (dissacharides or polysaccharides) is called condensation , water molecules is generated in the process, the reverse process is known as hydrolysis. sugar can be hydrolyszed at room temperature by the action of enzymes. Sugars can be hydrolyzed by the action of enzymes: Invertase: Hydrolyzes sucrose (table sugar) into glucose and fructose. Yeast normally secretes this enzyme. Lactase: Hydrolyzes lactose in milk. Many adults do not produce lactase and cannot digest lactose.

The concentration of a solution is the amount of a constituent divided by the total volume of the mixture. When water is added to a solution, the total volume increases, but the number of moles of solute remains the same. This results in a decrease in concentration.

When photographic film is exposed to sunlight, it undergoes a chemical reaction that converts light energy into chemical energy. This reaction causes the film to change chemically and appear black, spoiled, or unable to be developed.The silver bromide in the film breaks down into silver grains. The film produces free silver, which appears as black spots. The chemical equation for this reaction is: 2 AgBr → 2 Ag + Br2 Ag gains an electron to become reduced to Ag metal. -Option B

Lime is by far the most widely used neutralizing agent for industrial acidic waste waters. Lime, also known as calcium hydroxide, reacts with the acidic components in waste to form water, salts, and other less harmful compounds.

The bonds between the molecules in plastic are very strong, so microorganisms can't break them down.Thus, they are non-biodegradable.

Ernest Rutherford's alpha-scattering experiment led to the conclusion that atoms are mostly empty space, with a nucleus that contains the atom's positive charge.

The compound R formed with R(NO3)2 shows that the metal R has a valency of +2. If R reacts with tetraoxosulphate(VI), SO4 2- has a valency of - 2. If both react or combine together, their valencies will cancel out each other, which implies the formula will be RSO4.

Boyle's Law states that the volume of a given mass of gas is inversely proportional to its pressure at a constant temperature. As particles are constantly moving and colliding with each other and the walls of their container. The particles are far apart, so the forces between them are negligible. When a gas is compressed, the gas particles move faster and hit the walls of the container more often. This increases the pressure of the gas and invariably brings the molecules of the gases closer together, and this leads to a decrease in the average distance between them.

According to the equation 2NH3 → N2 + 3H2 2x22400cm 3 of ammonia will produce 3x22400cm 3 of hydrogen if 100cm3 of NH3 is used H2 volume = 100/2x22400 x 3 x22400 = 150cm3

Ammonia gas, NH3 is given off.

The major factor to consider when selecting a method for preparing a simple salt is the salt's solubility in water: Soluble in water: A salt can be prepared by titration. Insoluble in water: A salt can be prepared by precipitation. In this method, the insoluble salt is precipitated, washed, and dried.

Trioxonitrate(v) acid will only form one type of salt because it is a monobasic acid i.e. it contains only one replaceable hydrogen atom.
