liq [111]4 years ago
6 0

Answer:

1s2 2s2 2p6 3s2 3p6 3d4 4s2

Explanation:

Cobalt has twenty seven electrons hence Co3+ has twenty four electrons. It has lost three electrons from its valence shell. In filling the orbitals, we keep in mind that the energy of the 4s level is higher than that of the 3s level when a transition metal forms a complex hence the 4s is filled before the 3s level as shown in the answer above.

Gre4nikov [31]

The correct answer is B. An observation

Explanation:

An observation is defined as a statement or conclusion you made after observing or measuring a phenomenon, this includes statements based on precise instruments. For example, if you conclude a plant grows 2 inches every month by measuring the plant during this time, this is classified as an observation. The conclusion of the student is also an observation because he concludes this after analyzing the volume of the water in the cylinder through the lines in the graduated cylinder, considering the water is just in the middle of 100 mL and 200 mL which indicates there are 150 mL of water.

Short note of parents as inspires​
REY [17]

Answer:

My role models are my parents. They are my pillars of strength. They are my guide and give me the courage to battle obstacles in life.

My mother, being a working professional, manages all her work perfectly and with efficiency.

My father goes to office, but still does not forget to help me with my studies. They always encourage me in every aspect and motivate me even when I do not succeed.

My mother always smiles, no matter what the circumstances are and that gives me the strength and inspiration to face all problems.

My parents have made me understand what life is about and how to find that little ray of happiness in difficult situations.

What I am today and what I will become in future involves the support and affection of my parents. They have made me disciplined, dedicated and sincere.

A role model does not have to be a famous personality. It can be anyone who makes us believe in ourselves.

My parents fill sweetness in my life. From childhood I have learnt everything from my parents.

Not just parents, I also consider my teachers as role models. Even they guide me and show the path of success.

They have turned me into a fighter in the war of life
