<h2>Orderly Internal Arrangement of Atoms</h2>
Explanation:
- Crystals have an orderly internal arrangement of atoms arranged in a lattice pattern.
- Crystalline structure is generally known as an ordered arrangement of the particles like ions, molecules, or atoms that are placed altogether in a three-dimensional space of a lattice.
- The repeating pattern is known as a unit cell of the structure which is the smallest group of particles of the whole crystal structure.
Answer:
Add more pieces of zinc (2n) to the mixture
Heat the hydrochloric acid (HC) solution.
Explanation:
The reaction rate is simply the speed of the reaction. It is usually monitored by the rate at which the concentration of either of the reactants or products are changing per unit of time.
The factors affecting the rate of reactions are:
- Nature of the reactants
- Concentration or pressure of gases
- Temperature of the reaction
- Availability of catalysts
- Sunlight
In this problem, if the concentration of the zinc increases, the rate of reaction will increase.
If the temperature of HCl increases, so also the rate of the reaction.
Answer:
B. The substance is in the liquid state.
Explanation:
The symbol (l) in a chemical equation represents that the substance is in liquid state which is one of the physical states of a chemical substance.
