Explanation

The correct rate equation for the hypothetical reaction aA + bB → cC + dD is Rate = k[A]^a[B]^b.

This equation indicates that the rate of reaction depends on the concentrations of reactants A and B raised to the power of their respective stoichiometric coefficients.

Explanation

The formula for sulfuric acid is H2SO4.

It indicating that one molecule contains two hydrogen atoms, one sulfur atom, and four oxygen atoms.

Explanation

Explanation

The difference of lithium from the other alkali metals is mainly because of small radius and high charge density.

Lithium has a smaller atomic radius compared to other alkali metals.

This resulting in a higher charge density that leads to stronger ionic interactions and unique chemical properties.

Explanation

The correct ideal gas equation is PV = nRT.

Where P is pressure, V is volume, n is the number of moles, R is the ideal gas constant, and T is temperature in Kelvin.

This equation relates these properties for an ideal gas under various conditions.

Explanation

The number of moles is directly proportional to the mass of an element.

It is calculated by dividing the mass of the element by its molar mass.

Explanation

The -NH₂ group is an electron-donating substituent that releases electrons to the benzene ring through resonance.

It increasing the electron density on the ring.

Explanation

The principle that states that if a stress is applied to a system at equilibrium, the system will nullify the effect of the stress as far as possible is known as Le Chatelier's principle.

This principle helps predict how a change in conditions (like concentration, temperature, or pressure) will affect the position of equilibrium in a chemical reaction.
