Answer: Option (c) is the correct answer.
Explanation:
A monomial is defined as an algebraic expression in which there is only one term present.
For example, 3x is a monomial.
A binomial is defined as an expression where there will be two terms present. For example, is a binomial.
A polynomial is defined as an algebraic expression which contains more than two terms.
For example, is a polynomial.
Thus, we can conclude that the given expression is a polynomial.
Considering the reaction stoichiometry, the amount of moles of NO that is produced when 27 moles of HNO₃ react is 6.75 moles.
<h3 /><h3>Reaction stoichiometry</h3>The balanced reaction is:
3 Cu + 8 HNO₃ → 3 Cu(NO₃)₂ + 2 NO + 4 H₂O
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
It is possible to determine the the amount of moles of NO produced by a rule of three: if by stoichiometry 8 moles of HNO₃ produce 2 moles of NO, if 27 moles of HNO₃ react how many moles of NO will be formed?
<u><em>amount of moles of NO= 6.75 moles</em></u>
In summary, the amount of moles of NO that is produced when 27 moles of HNO₃ react is 6.75 moles.
