c. dmitri mendeleev
d. sir issac newton

  C. Dmitri Mendeleev

Explanation:  Dmitri Mendeleev was the first scientist who initiated the arrangement of elements in the regular pattern which is known as the Periodic table of Elements.

He tried to arrange these elements on the basis of the chemical properties and on the basis of their atomic number.

Atomic number was considered as the basis of the periodic table as it is the most basic and essential property of the elements.

the ratio of the conjugate base to the acid required to attain the desired ph.

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
