Explanation:

Haemoglobin is a protein found in red blood cells that is responsible for transporting oxygen from the lungs to the rest of the body.

Iron is an essential component of haemoglobin, as it is responsible for binding to oxygen.

The percentage of iron by mass in haemoglobin is approximately 0.33%.

The molecular mass of haemoglobin is 67200.

To find the number of iron atoms in each molecule of haemoglobin, we need to use the following formula:

Number of iron atoms = (percentage of iron by mass / atomic mass of iron) x molecular mass of haemoglobin

Substituting the values in the formula, we get:

Number of iron atoms = (0.33 / 55.85) x 67200

Number of iron atoms = 4

Therefore, the correct answer is option (b), which states that there are four iron atoms in each molecule of haemoglobin.

Iron content in haemoglobin = 0.33%by mass=0.33% of molecular mass=67200*0.33/100=221.76 it means this amount of mass of iron in 1 molecule of haemoglobin. number of iron atom present =221.76/atomic mass =221.76/56=3.96~4

Attempt All sub parts from each question.Molecular Perspective In water, there are two types of molecules. Some molecules are at the surface, called exterior molecules, and some molecules are inside, called interior molecules. The interior molecules are attracted to all the molecules around them. The exterior molecules are attracted to only the other surface molecules and to those below the surface. So that the energy state of the molecules on the interior is much lower than that of the molecules on the exterior. The molecules always try to maintain a lower energy state and hence the exterior molecules experience a downward force. This force is known as cohesive force. As a result they try to maintain a minimum surface area, thus allowing more molecules to have a lower energy state. Thus surface tension is created. The water molecules attract one another due to the water molecule’s polar property. The hydrogen ends, which are positive in comparison to the negative ends of the oxygen, cause water to "stick " together. This is why there is surface tension. Water has very high surface tension. It is 72.8 milli newton per meter at 20°C.Q. Which one of the following is the correct molecular structure of water molecule?

Two containers X Y are present with container X consisting of some mass of He at some temperature while container Y having double the volume as that of container X kept at same temperature containing same mass of H2 gas as the mass of Helium gas. Based on this data the following conditions answer the question that followsAssume sizes of H2 molecule He atom to be same size of Hatom to be half to that of Heatom only bimolecular collisions to be occuring.Condition I: all except one atom of He are stationary in cont. X all molecules of H2 are moving in container Y.Condition II: both containers contain all moving moleculesQ. Assuming condition I to be applicable if no. of total collisions occuring per unit time is A in container X then no. of total collisions made by any one molecule in container Y will be
