4 moles

Explanation:

Given parameters:

number of moles of reacting NO = 24moles

Equation of the reaction:

    4C₃H₆     +     6NO    ⇒     4C₃H₃N   +  H₂O    +     N₂

Solution:

The moles is synonymous the quantity of matter that contains the avogadro's number of particles.

To solve this problem, we must ensure that the given equation is balanced by simply inspecting.

 The equation is balanced by inspection.

From the balanced equation;

          6 moles of NO reacted to produce 1 mole of nitrogen gas

        24 moles of NO will therefore produce    \frac{24}{6} = 4 moles

Exponatial notation is used for a/ writing very small numbers b/writing very large numbers c/avoid tedious work d/all above
morpeh [17]

Answer:

The correct answer is option d/ "all above".

Explanation:

Exponential notation is a way of expressing mathematical equations by simplifying numbers that could be very small or very large. The number included within the exponential notation (the exponent) describe how many times the number included in the base is multiplied. If the exponent is an integer the number is very large, while if the exponent is a ratio the number is very small. This avoids the tedious work of writing the complete number that results from the exponential multiplication.
