Which statement is correct for the reaction below?4X+Z yields 2R+2S
A: The rate of formation of R is one-half the rate of the disappearance of Z.
B: The rate of disappearance of Z is one-fourth of the rate of disappearance of X.
C: The rate of formation of R is double the rate of formation of S.
D: The rate of formation of S is double the rate of disappearance of X.
Answers
B: The rate of disappearance of Z is one-fourth of the rate of disappearance of X
Because as x -> 0, 4->0
z-> 0, 1->0

Final answer:
A solution is a homogeneous mixture and does not necessarily have to include a liquid component. It can exist in gas, liquid, and solid states. Examples include air (a gas solution) and alloys (a solid solution).
Explanation:
No, a solution doesn't always have to involve a liquid. This is a common misunderstanding because water is often used as a solvent, which leads many to associate solutions with liquids. However, solutions can exist in all states of matter: gas, liquid, and solid.
A solution is a homogeneous mixture of two or more substances. The substance present in the largest quantity is usually the solvent, and substances in lesser amounts are the solutes.
For instance, air is a gaseous solution involving nitrogen, oxygen, and various other gases. Alloys, like the nickel dissolved in copper in US five-cent coins, are examples of solid solutions. Therefore, while often associated with liquids, solutions can exist across various physical states.

Further Explanation:
Rutherford’s experiment:
Rutherford's model of atom is the classic model of the atom instead of having many limitations. He designed an experiment that used alpha particles emitted by radioactive elements as objects that can demonstrate the structure of the atom. Rutherford showed his own physical model for the subatomic structure as a result of the experimental observations.
The postulates of Rutherford’s model are as follows:
1. An atom consists of a positive charge in a very small volume. Most of its mass is concentrated in a very small region of the atom and this region was termed as the nucleus of the atom.
2. The nucleus of the atom is surrounded by the negatively charged particles which were called electron. These electrons were supposed to revolve around the atomic nucleus in a circular path at a very high speed. This circular path is called orbit.
3. A very strong electrostatic force of attraction holds together the negatively charged electrons revolving around the nucleus positively charged concentrated in the nucleus.
Limitations of Rutherford’s model:
1. It did not tell anything about the distribution of electrons in various orbits.
2. This model failed to explain Maxwell’s theory of electromagnetic radiation.
3. It was unable to explain the stability of an atom.
Therefore most of the volume of an atom is taken up by empty space in the atom.

- Crystals are solids that are made up of particles such as molecules, atoms or ions, which are arrange in a highly ordered microscopic structure, forming a crystal lattice which extends in all directions.
- Examples of crystals include quartz, that is made up of silicon (iV) oxide molecules that are arranged in a lattice,table salt is another example that is made up of sodium and chloride ions that are arranged in a lattice
- Crystals are very ordered, they may be made up of atoms of the same elements or atoms of different elements such as in the case of table salt.

As the temperature of liquid increases, its vapor pressure increases. Therefore, option (2) is correct.
What is vapour pressure?
Vapour pressure can be defined as the pressure exerted by a vapor with its condensed phases in a closed system at a given temperature. The equilibrium vapor pressure is also served as an indicator of the rate of evaporation of a liquid.
A material that has a high vapor pressure at normal temperatures is commonly referred to as a volatile material. The pressure exhibited by the molecules of the gas above a liquid surface is called vapor pressure.
The temperature and the vapor pressure of liquid are directly related to each other. If the temperature of the liquid increases, more gasmolecules have the energy to escape from the surface of the liquid.
Therefore, the vapor pressure increases with an increase in the temperature of the liquid.
