Answer:
C. The electrons are closer to the atom with the higher
electronegativity.
Explanation:
In a covalent bond, the electrons are shared equally when the atoms involved have the same electronegativity. However, when there are differences of electronegativity between those atoms, the electrons preferred are closer to the atom with the higher electronegativity.
Answer:
C) Reactants absorb a minimum amount of energy and then release a smaller
amount of energy as products form.
Explanation:
The statement that best describes how to read a reaction pathway from the graph of an endothermic reaction is that, reactants absorb a minimum amount of energy and then release a smaller amount of energy as products form.
In an endothermic change, heat is absorbed from the surrounding.
- As such, the surrounding becomes colder at the end of the reaction.
- On a graph of an endothermic reaction, the reactants absorbs a minimum energy.
- As the reaction proceeds, the products gives off an even lesser amount of energy.

Once the student has finished his experiment, additional steps he may take are to analyze the data gathered and draw a conclusion, then publish his findings to be seen by his peers (other students).
<h3 /><h3>What comes after the experiment?</h3>
- Once an experiment is concluded, one must go over the data gathered.
- By this, we mean to analyze the information obtained through the experiment.
- This allows the student to draw a conclusion backed by evidence.
- Once complete, it is wise to share and discuss the findings with peers.
Therefore, we can confirm that once the experiment is completed, the most common action that follows is to draw a conclusion based on the analysis of the data gathered during the experiment, then discuss the findings with peers.

the atomic mass of tungsten is 183.84 grams
this is the mass of one mole of tungsten we know that one mole of any substance contains Avagadro number of atoms or molecules or ions.
So one mole of tungsten metal will have 6.023 X 10^23 atoms
thus mass of 6.023 X 10^23 atoms is 183.84 grams hence mass of single atom = 183.84/ 6.023 X 10^23 atoms
= 30.52 X10^-23 = 3.052 X 10^-22 g
