Rosa was looking for patterns to predict the products of chemical reactions. she recorded three similar decomposition reactions in the table.

a 2-column table with 3 rows. the first column labeled reactants has entries 2 n a c l o subscript 3, 2 k c l o subscript 3, 2 l i c l o subscript 3. the second column labeled products has entries 2 n a c l + 3 o subscript 2, 3 o subscript 2 + 2 k c l, empty.

what products should she record in the last row of the table?

answer: at 24 february, 2014 the population gets twice of its initial population.

explanation:

since we have given that

the population for alpha city, t years after january 1, 2004 is given as

first we find out the initial population, i.e. t=0,

so, our quadratic equation becomes,

according to question, we have said that if the population has twice its initial population, then it becomes

so, time taken to reach this above mentioned population is given by

now, we know that time can't be negative so, we take t=9.149 years.

hence, at 24 february, 2014 the population gets twice of its initial population.

where’s the list ? the question is incomplete
