Answer:
a. form a hypothesis, conduct an experiment, record data, make a conclusion
Explanation:
Performing scientific investigations involved following the SCIENTIFIC METHOD, which is a rule or guideline followed in order to discover knowledge about natural phenomena. The scientific method has been divided into steps viz:
- Making observation/asking questions: In this case, the problem is HOW ANTS FEED.
- Formulating hypothesis: The hypothesis is a testable explanation given to solve the asked question.
- Testing hypothesis: The hypothesis must be able to be tested via conducting an experiment.
- Analyze result: The results of the test is recorded and analysed as data.
- Make conclusions: The conclusion either accepts or rejects the hypothesis depending on the result of the experiment.
Therefore, based on this; form a hypothesis, conduct an experiment, record data, make a conclusion are the steps Colby should take to best study the feeding patterns of ants
Answer:
<h2>hydrogen gas is produced .</h2>
CO2 is the emperical formula of carbon dioxide
Answer:
-) Oxidizing agent: 
-) Reducing agent: 
Explanation:
The first step is separate the reaction into the <u>semireactions</u>:
A.
B.
If we want to balance in <u>basic medium </u>we have to follow the rules:
1. We adjust the oxygen with 
2. We adjust the H with 
3. We adjust the charge with 
Lets balance the first semireaction A. :
Now, lets balance semireaction B:
Finally, we have to add the two semireactions:
_________________________________________
_________________________________________
Cancel out the species on both sides:
Simplifying the equation :
The is <u>oxidized</u> therefefore is the <u>reducing agent</u>. The is<u> reduced</u> therefore is the <u>oxidizing agent</u>.
