Explanation:
Average heart beat = Number of heart beats/ time
7.0 years = 7.0 * 365 * 24 * 60 = 3679200 minutes
If there are 69 beats in 1 minutes
There are x beats in 3679200 minutes
x = 253865 beats
x = 254000.00 beats ( to 3 sf)
beats in 7.00 years = 254000.000 beats
beats in 7.000 years = 254000.0000 beats
Assuming that you mean table sugar (sucrose), then at room temperature and without any catalyst, there is no reaction.
However if you elevate and hold the temperature of the aqueous solution at 50 to 60 °C (especially in the presence of a suitable catalyst, like mineral acid) the sucrose dimer will split into glucose and fructose. This is called hydrolysis and the resulting solution is called an invert sugar solution.
The reaction could be written as:
C12H22O11 (sucrose) + H2O (water) → C6H12O6 (glucose) + C6H12O6 (fructose)
or
C12H22O11 (aq) + H2O (l) → C6H12O6 (aq) + C6H12O6 (aq)
Notice that both of the produced sugars have the same empirical formula. Check with your instructor or in your textbook to see if more exact formulas are needed.

Electronegativity refers to the ability of an atom to attract shared electrons in a covalent bond. The higher the value of the electronegativity, the more strongly that element attracts the shared electrons.
