faust18 [17]

Answer:

Explanation:

A) Reactant that can produce more of the product

Excess reactant:

In a given reaction, the reactant that is in excess supply is the excess reactant. If the amount of the excess reactant is match, more of the product will be produced.

B) Reactant that can produce a lesser amount of the product

Limiting reactant

The limiting reactant restricts the progress of the reaction. It determines the amount of product that can be formed.

C) Amount of product predicted to be produced by the given reactants

Theoretical yield

For a given amount of reactants, the theoretical yield determines the amount of products that can be produced.

A typical person has an average heart rate of 75.0 beats/min. Pay close attention to significant figures in this question.
frozen [14]

The number of beats  the person have in 1.7 years is  6.7 x 10⁷ beats.

<h3>Number of beats of the person</h3>

The number of beats of the person is calculated as follows;

n = bt

where;

  • b is the beat rate
  • n is number of beats
  • t is time or duration

b = 75 beats/min

t = 1.7 years = 893520 mins

n = 75 beats/min x 893520 mins

n = 67,014,000

n = 6.7 x 10⁷ beats

Thus, the number of beats  the person have in 1.7 years is  6.7 x 10⁷ beats.
