Answer:
F < O < Cl
Explanation:
Fluorine has a greater effective nuclear charge than oxygen does, meaning that the electrons are drawn tighter and closer toward the nucleus. Fluorine has 9 protons and 9 electrons while oxygen only has 8 protons and electrons. Chlorine has a larger atomic radius than both fluorine and chlorine because has another energy level (shell). Although chlorine has the same effective nuclear charge as fluorine, chlorine has more electrons, 17, which requires an additional shell to contain them.
0.115 M means that 0.115 moles of KBr are contained in a volume of 1000 ml, therefore a volume of 350 ml will have (0.115 × 0.35) = 04025 moles
From the formula of molarity moles = molarity × volume in liters
1 mole of KBr is equivalent to 119 g
Therefore, the mass = 0.04025 × 119 g = 4.79 g
Answer:
There is one scientific method
it starts with an
OBSERVATION
then a HYPOTHESIS
which goes to planning, creating an EXPERIMENT
and finally a conclusion for your results
Explanation:
The statement “Only the “Conclusion” section discusses whether the original hypothesis was supported, and both sections suggest further research”, best describes the difference between analysis and conclusion.
Answer: Option 4
<u>Explanation:
</u>
In research, we do experiments and derive the results. Then, those results were analyzed by us. In this analysis part, we compare our results with the related results published elsewhere. Also, we correlate the similarities and point out the differences between our analysis and other reported results.
In conclusion part, we have to check hypothesis or it supported. And, we summarise our analysis and figure out the further research need to be done on that to improvise our research. So, the final statement is the correct option which best describes the difference between analysis and conclusion.
