In an experiment the chemical reaction between a piece of aluminum foil and copper(ii)chloride solution in a beaker is observed. the aluminum seems to disapear over time. the balanced chemical equation is given by: 2 al + 3 cucl ⇒3 cu +2 alcl3

can you predict the outcome of the same experiment when aluminum is replaced with a more reactive element such as silver?

a) no reaction would occur.
b) the silver would disappear but no solid precipitate would form.
c) the silver would disappear and a silver solid precipitate would form.
d) the silver would disappear and a brownish red solid precipitate would form.

hint: what would the new product be?

A)No reaction would occur.

Explanation:

Single replacement reaction is a chemical reaction in which more reactive element displaces the less reactive element from its salt solution.

Example:

Thus When aluminium is treated with copper chloride ,aluminium being more reactive than copper displaces copper from its salt solution and thus produce aluminium chloride.

But when aluminum is replaced by silver, o reaction would occur as silver is less reactive than copper and hence would not be displace it from its salt solution.

i think if it were me i whould divide 300 dide 15

step-by-step explanation:

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6
