Answer:
B) 2-6-2 is in excited state
I believe the correct answer from the choices listed above is the second option. The statement that best describes the most concentrated solution would be that it <span>has the most solute for a given volume. Concentration is oftentimes expressed as amount of solute per unit of volume. Hope this answers the question.</span>
Answer:
The nucleus of an atom is made up of a dense ball
of <u>protons</u> and <u>neutrons</u> surrounded by <u>electrons.</u>
Explanation:
We know that an atom consist of electrons, protons and neutrons. Neutrons and protons are present inside the nucleus while electrons are present out side the nucleus. Electron has a negative charge and is written as e⁻. The mass of electron is 9.10938356×10⁻³¹ Kg . While mass of proton and neutron is 1.672623×10⁻²⁷Kg and 1.674929×10⁻²⁷ Kg respectively.
Symbol of proton= P⁺
Symbol of neutron= n⁰
The number of electron or number of protons are called atomic number while mass number of an atom is sum of protons and neutrons. The umber of protons and electrons are always equal to make the atom electrically neutral and when an atom loses its valance electron the number of protons increases and thus positive charge increased and atom form cation.
Answer:
What are the correct coefficients when this chemical equation is
balanced? *
P4 + 02 P2O5
<h2>1, 5, 2</h2>
Explanation:
For this reaction we have a combination reaction. Balancing Strategies: This combination reaction is a lot easier to balance and if you can get an even number of oxygen atoms on the reactants side of the equation.
They call it H2O because it has 2 Hydrogen molecule and 1 Oxygen molecules <span />
