Answer:
The least whole number coefficient for HNO₃ is 6
Explanation:
The chemical equation above is the reaction between calcium orthophosphate and nitric acid.
To balance a chemical equation, we have to consider law of conservation of matter which states that matter can neither be created nor destroyed.
What this law implies is that, whatever we have at the reactant side must be equal to whatever is obtainable at the product side.
The above equation is
Ca₃(PO₄)₂ + HNO₃ → Ca(NO₃)₂ + H₃PO₄
To balance the equation, we'll have to check the number of atoms at each side and possibly balance the equation with the number of moles.
The balanced equation is
Ca₃(PO₄)₂ + 6HNO₃ → 3Ca(NO₃)₂ + 2H₃PO₄
From the balanced equation above, we can see that the number of calcium (Ca), Phosphorus (P), Oxygen(O), Nitrogen(N) and hydrogen (H) are balanced at both sides of the equation.
The least number coefficient for HNO₃ is 6

Answer:
Correct options:
Organic compounds can be synthesized in a laboratory setting.
There are hundreds of thousands of organic compounds.
Explanation:
1) Organic compounds are only found in living things: False
Organic compounds are mainly carbon based. Although organic compounds are derived from living things like plants and animals, non-living things like sedimentary rocks are also rich in carbon.
2) Organic compounds can be synthesized in a laboratory setting: True
There are four major categories of organic compounds: carbohydrates, proteins, lipids and nucleic acids all of which can be synthesized in a laboratory.
3) Organic compounds contain carbon: False
Organic compounds are identified by the presence of both carbon and hydrogen (and sometimes other elements like O, N, S).
4)CO2 is an organic compound: False
There are no H atoms, hence CO2 is not organic.
5) There are hundreds of thousands of organic compounds: True
