Carbon and oxygen combine to form carbon dioxide. What are the products, or what is the product, in this chemical reaction?
VladimirAG [237]

The product in this chemical reaction is Carbon Dioxide or CO2.

This is because it states, "To form," which means that it was produced from the reactants Carbon and Oxygen.

To know what the products are in a statement rather than an equation, words such as produced and formed are used.

Hope this helps!

Describe why it is important that scientific experiments be repeated
defon

Answer:

Scientific experiments need to be repeated so that scientists can make sure the results are as accurate as possible.

Explanation:

The point of a scientific experiment is to find the answer to a question. If a scientist performs an experiment only one time, they might find an answer to their question. However, they might have messed something up, so the answer is completely wrong. Doing an experiment momre than once can help a scientist make sure that their answer is correct. I hope this helps!
