Answer:
The Atomic Number of the atom of an element whose model is given is "8" that is option no. 'C' in the question.
Explanation:
An Atom comprises of 3 basic structures that are Protons, Neutrons and Electrons. The central part is the Nucleus which contains protons and neutrons having positive charge and no charge respectively. The electrons are revolving around the nucleus in electronic shells having the negative charge.
<u><em>ATOMIC NUMBER: </em></u>
Atomic number is the number of protons present inside the nucleus of an atom and it determines the place of that particular atom in the <u>Periodic Table.</u>
In the model, given in the question, the nucleus contains 2 types of balls dark gray colored and light gray colored. The key at the bottom shows the dark gray colored ball as having a positive charge and thus it represents the atomic number for the given atom of element which is <u><em>EIGHT (8).</em></u>
So, the atomic number for the given atom is 8 which is element OXYGEN.

Answer:
The enthalpy of the reaction is 64.9 kJ/mol.
Explanation:
..[1]
..[2]
..[3]
..[4]
2 × [2] - [1]- [3] = [4] (Using Hess's law)



The enthalpy of the reaction is 64.9 kJ/mol.
Answer:
All offspring are tall when a homozygous tall parent with homozygous short parent.
Explanation:
When we crossed homozygous tall parent with homozygous short parent, we conclude that all offspring are tall, because homozygous short parent are supressed under the homozygous tall parent, due to law of dominance.
Law of dominance states that, recessive alleles are suppressed by dominant alleles but they can appear in F2 generation.
Using a punett square, we can predict the cross between homozygous tall and homozygous short parent.
The phenotypes are: All are tall plants (4:0).
