So, the expression 10 + 2p - 3r10+2p−3r10, plus, 2, p, minus, 3, r equals 333 when p = 4p=4p, equals, 4 and r = 5r=5r, equals, 5

p = 6

Explanation:

Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

3p - (2 • 5)     3p - 10

————————————  =  ———————

     5              5  

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
