describe how you could use research and the scientific method to test a claim that organic foods are better than natural foods.

Use complete sentences, state your hypothesis and explain specifically how you would conduct the research and gather the data that you will use. You do not have to conduct the experiment, only explain what you would do and how you would analyze the results.

Natural food is not regulated - there is no rule or regulation. Food manufacturers can label any food as "natural". 

Orgranic food is regulated by USFDA and must follow rules and regulations during material selection and processing.  It must also passed inspections to maintain its "organic" label.

So the hypothesis is organic foods are better than natural foods. An experiment can be conducted to test this claim. Food ingredients are listed in all food labels. Visit the local supermarket and copy down the ingredients lists of both orgranic and natural foods.
 
Correlate the ingredients in two separate columns labeled organic and natural. Look them up to see if they are healthy; or man-made/processed.  If there are more healthy ingredients in organic foods, the results support the claim.

Natural food is not directed - there is no run or control.<span>
So the speculation is natural foods are superior to characteristic foods. An analysis can be led to test this claim. Food fixings are recorded in all food names. Visit the nearby general store and duplicate down the fixings arrangements of both organic and regular foods.

Explain why CaCl2 is likely to have properties similar to those of CaBr2
qaws [65]

Answer:

Because both CaCl2 and CaBr2 both contain elements (Chlorine and Bromine) from the same group (group 7)

Explanation:

Elements are placed into different groups in the periodic table. Elements in the same group are those that have the same number of valence electrons in their outermost shell and as a result will behave similar chemically i.e. will react with other elements in the same manner.

Chlorine and Bromine are two elements belonging to group 7 of the periodic table. They are called HALOGENS and they have seven valence electrons in their outermost shell. Hence, when they form a compound with Calcium, a group two element, these compounds (CaCl2 and CaBr2) will possess similar properties because they have elements that are from the same group (halogen group).

How many moles of H2O are needed to produce 5.6 mol of NaOH?<br> Na2O + H2O --&gt; 2NaOH
navik [9.2K]

Answer: 2.8 moles

Explanation:

The balanced equation below shows that 1 mole of sodium oxide reacts with 1 mole of water to form 2 moles of sodium hydroxide respectively.

Na2O + H2O --> 2NaOH

1 mole of H2O = 2 moles of NaOH

Let Z moles of H2O = 5.6 mole of NaOH

To get the value of Z, cross multiply

5.6 moles x 1 mole= Z x 2 moles

5.6 = 2Z

Divide both sides by 2

5.6/2 = 2Z/2

2.8 = Z

Thus, 2.8moles of H2O are needed to produce 5.6 mol of NaOH
