Le-Chatelier’s Principle states that when a system is in equilibrium and a stress is applied, the system responds by acting in a way that, to the greatest extent feasible, negates the impact of the stress and keeps the system in equilibrium. This rule applies to all types of equilibrium, such as thermal, chemical, etc.

The transition temperature is the temperature at which a substance’s allotropic forms are in equilibrium.Potassium nitrate (KNO3) changes from an orthorhombic crystal structure (α-phase) to a rhombohedral crystal structure (β-phase) at atmospheric pressure when heated above the transition temperature of about 123°C.

1 mole of H2SO4 has 32g Sulphur.

Thus, (1.5 x 32)g of sulfur, or 48 grams, are present in 1.5 mole of H2So4.

The reaction’s balanced chemical equation is provided below.

4Al + 3O2 → 2Al2O3

The molar mass of oxygen gas is 32g, whereas that of aluminum is 27g. According to the equation above, 3×32 = 96, meaning that 96g of oxygen is needed to fully react with 4×27 = 108g of aluminum. So

108g of aluminium → 96g of oxygen

1g of aluminium → (96 / 108) of oxygen

so 27g of aluminium → (96 x 27) / 108 of oxygen = 24g of oxygen

Any reaction’s half-life can be calculated, but the precise calculation technique will vary depending on the reaction’s order.

Glyoxal, or C2H2O2, is created when tetrahydroxy ethane C2H6O4 loses two water molecules and two H2O.

One common illustration of an electrophilic addition reaction is the reaction between ethene and bromine. The first stage of this reaction is the creation of an intermediate known as a bromonium ion. This is created when a bromine molecule is added across the ethene double bond. A cyclic intermediate with a positive charge on the bromine atom is the bromonium ion. The (A) option provides the accurate depiction of the reaction’s intermediate. Because of its high reactivity, this intermediate can combine with a nucleophile to create the finished product.

The collection of materials and energy under study is called a system. For instance, if reactions are taking place in a jar, the surroundings are everything outside the jar, and the system is everything within. Everything outside of the system, or the rest of the cosmos, is referred to as the surrounds.
