Answers
Answer: The correct answer is Option B.
Explanation:
Photosynthesis is defined as a process in which a plat uses carbon dioxide reacts with water in the presence of sunlight to produce glucose as a product, oxygen and water as a byproduct.
The chemical equation for this reaction follows:
By Stoichiometry of the reaction:
6 moles of carbon dioxide reacts with 12 moles of water in the presence of light to produce 1 mole of glucose, 6 moles of oxygen and 6 moles of water.
Hence, the correct answer is Option B.

J. J. Thomson worked in the field of chemistry and proposed the atomic model theory after the discovery of the electron. He proposed the plum pudding model. Thus, option A is correct.
What is the plum pudding model of the atom?
The plum pudding model of the atom was proposed by J.J. Thomson, after the discovery of electrons. The “plum pudding” atomic model was based on the plum cake structure where the sub-atomic particles were placed.
According to the model, the electrons being negative species were embedded as the cherries in the structure, while the protons being positive in charge were freely present in the rest of the pudding.
Therefore, Thomson proposed the “plum-pudding” atomic model.

All the elements of group 1 in the periodic table are known as alkali metals. These are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (fr).
Characteristics of alkali metals are as follows.
- Alkali metals are soft and can be cut with a knife.
- They are good conductors of heat and electricity.
- They have only 1 electron in their outermost sub-shell.
- They are very reactive.
- Alkali metals are ionic in nature.

A rate equation can be written based on the rate constant k, concentration of reactants and half life time t1/2 of reactant if given. [A⁰] is the initial concentration of reactant A and [A]t be the final concentration.
What is rate of reaction?
Rate of a reaction is the rate of decrease in concentration of reactants or rate of increase in concentration of products. Rate of the reaction written in terms of molar concentration of reactants is called the rate law.
Consider the simplest reaction A gives B. Here the only one reactant is A. The molar concentration of A is written as [A]. The rate constant k is then,
k = [B] / [A]
If any coefficients attached with them it is written as power of the concentration term. Now, the rate of the above reaction is written as follows:
rate r = k [A]
Sometimes the initial and final concentrations of A can be considered. Where, [A⁰] is the initial concentration and [A]t be the final concentration.
The half life t1/2 is the time taken to consume half of the reactants concentration.
