The prevention of fruits browning is the result of :
>slowing the rate of enzyme reaction
The browning of fruits can be slowed down by preventing the enzyme from working properly. Lemon juice contains an acid which can stop enzymes from working properly. For example, water and sugar in jam prevents oxygen in the air to reach enzymes and hence protects from browning.
Always keep cut fruits such as apples, pears and peaches from turning brown by coating them with an acidic juice such as lemon or orange.
The enzyme that is responsible for the browning is called polyphenol oxidase. PPO enzyme in the presence of oxygen changes substances known as phenolic compounds, through oxidation, into quinones.

Explanation:
OB. Concentration
OC. Mass
OD. Volume
Molarity is a measure of concentration in a solution.
Molarity is a measure of concentration in a solution. It represents the amount of a solute dissolved in a given volume of solvent. Molarity is calculated by dividing the moles of solute by the volume of the solution in liters.
a.carbon?
Answer:
FeCl: Ferric Chloride (also called iron chloride), comes from Fe (ferrum, or iron), and Cl (Chlorine)
HNO: Nitroxyl, from N (Nitrogen), and the acidic nature of a radical ending in -yl.
NaSO: Sodium sulfate, Na (Sodium), S (Sulfur), O (Oxygen).
SO: Sulfur monoxide (Mono-One), O (Oxygen) and S (Sulfur).

Explanation:
Let's consider two kind of equations:
Answer:
every atom has no overall charge. because they contain equal numbers of positive protons and negative electrons. they cancel each other out making them a neutral atom.
There are two types of chemical compound one is covalent compound and other is ionic compound, covalent compound formed by sharing of electron and ionic compound formed by complete transfer of electron. Therefore, the name and formula of the compound made of magnesium and fluorine is Magnesium fluoride and MgF₂ respectively.
Chemical Compound is a combination of molecule, Molecule forms by combination of element and element forms by combination of atoms in fixed proportion.
An ionic compound is a metal and nonmetal combined compound. Ionic compound are very hard. They have high melting and boiling point because of strong ion bond.
The name and formula of the compound made of magnesium and fluorine is Magnesium fluoride and MgF₂ respectively. Magnesium fluoride is an ionic compound.
Therefore, the name and formula of the compound made of magnesium and fluorine is Magnesium fluoride and MgF₂ respectively.
