A zookeeper predicted the weight of a new baby elephant to be 272 pounds when it was born. The elephant actually weighed 304 pounds at birth. What was the percent error of the zookeeper’s prediction?

12.4%

Explanation:

The percent of error can be found by dividing the difference in weights by the predicted weight.

290 - 258 = 32 pounds

32/258 = 0.124

0.124 = 12.4% approximately was the percent of error

c- cold periods in earth's history during which glaciers covered much of the surface.

explanation:

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
