in cgs system, plank's constant= h=6.626 x10⁻²⁶ erg s
Value of Plank's constant in SI system= 6.626 x10⁻³⁴ Js
now 1 Joule= 10⁷ ergs
so h= 6.626 x10⁻³⁴ Js (10⁷ ergs/1J)
h=6.626 x10⁻²⁷ erg s
Explanation: We use a different element in the chemical equation.
We explain by a example
In this equation, we use the two elements Na and Cl.
Now, we count the number of atoms present on one side 2 atoms of Na and 2 atoms of Cl then the total numbers will be 4 .
But , we use a molecular formula then we count the number of each element of the molecular formula.

a specific way of pursuing a scientific question that involves performing an experiment and then constructing a hypothesis
The scientific method is a specific way of pursuing a scientific question that involves the systematic formulation, observation, testing, and modification of a hypothesis. Hence, option (C) is correct.
Since at least the 17th century, science has been developed using the scientific method, an empirical approach to information acquisition (with notable practitioners in previous centuries; see the article history of scientific method for additional detail.) Given that cognitive presumptions might skew how one understands the observation, it requires careful observation and the use of strong skepticism regarding what is observed.
It entails creating hypotheses through induction based on such observations, testing their testability through experimental analysis and measurement-based statistical testing of the conclusions drawn from the hypotheses, and then revising (or removing) the hypotheses in light of the experimental results. These are scientific method principles, as opposed to a predetermined set of processes that apply to all scientific endeavors.

There are 4 hydrogens on the right side , and 2 hydrogens on the left per molecule of . To get the same number of hydrogens on both sides, the coefficient should be 2.
(Then the number of oxygens will be consistent, since contributes 2 oxygens, and so does .)
The smallest unit that makes up matter is atom. The correct option is A.
The atom is the smallest component of matter. The fundamental units of matter, or atoms, cannot be further divided without losing their essentialcharacteristics.
They have an orbitally arranged nucleus of protons and neutrons that surrounds them. Molecules, which are collections of atoms bound together, are created when various atom kinds are combined.
On the other hand, cells, which are made up of different molecules, are the fundamental structural and functional units of living things.
Protons are subatomicparticles that can be found in the atom's nucleus, however they are not the tiniest piece of matter.
Thus, the correct option is A.
