Moles of Zn present= 2.36/65.4= 0.0361 moles
Therefore maximum moles of ZnO= 0.0722
Mass of one mole of ZnO= 81.4
Mass of ZnO produced= 0.0722 x 81.4= 5.87g
Also, remember, light energy (from the sun) is a reactant for photosynthesis. The plant uses water sunlight and carbon dioxide to make sugars as well as oxygen. Plants, the organisms that carry out photosynthesis, are typically the first ate organism is a Food chain and so most other organisms energy came from the plant somehow. But the plant got its energy from the sun.
Answer:
Hence the correct option is an option (b) Sr4, Cl,Br−,Na+.
Explanation:
Bromine and chlorine belong to an equivalent group. As we go down the group the dimensions increases which too there's a charge on the bromine atom. therefore the size of the Br- is going to be larger in comparison to the chlorine atom.
Sr atom is within the second group, and also it's below the above-mentioned atoms.so Sr is going to be the larger one among all the atoms.
Sodium and chlorine belong to an equivalent period .size decrease from left to right. but due to the charge on sodium its size decreases and there's an opportunity that Na+ size could be adequate for Cl.
Here we finally assume that two atoms are of an equivalent size (Na+ and Cl) which are less in size compared to the opposite two(Sr and Br-) during which one is greater (Sr)and the opposite is smaller(Br-).

The solvent is usually referred to as the component of a solution which is present as the one with the larger quantity and in most cases as the liquid which dissolves a solid. In a solution, there are two components namely the solvent and the solute. The solute is the one in smaller amount.
