Answers

Answer 1

Answer:

First of all what is your hypotheses? Finally, you've reached your conclusion. Now it is time to summarize and explain what happened in your experiment. Your conclusion should answer the question posed in step one. Your conclusion should be based solely on your results. Was your hypothesis correct? If your hypothesis wasn't correct, what can you conclude from that? Do you need to run your experiment again changing a variable? Is your data clearly defined so everyone can understand the results and follow your reasoning? Remember, even a failed experiment can yield a valuable lesson.

Answer:

Explanation:

The subscript numbers mean how many of that specific atom there are. So O(sub:2) would mean 2 oxygen atoms. If there is a normal number in front, you multiply all atoms by that number. So 6H(sub:2)O would be 6*2=12 Hydrogen atoms and 6*1= 6 oxygen atoms
