The graph above shows data from a scientific study measuring the heart rate of daphnia in different water temperatures. Researchers in the study want to test the heart rate of daphnia at 90 F. Based on the data which of the following is the best prediction of Daphne has heart rate at 90 F? a. 100 BPM
B. 125 BPM
C. 148 BPM

D. 210 BPM

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.

rosa was looking for patterns to predict the products of chemical reactions. she recorded three similar decomposition reactions in the table.she should record 2licl + 3o2.

in the last row of the table. it is the thermal decomposition of chlorate lithium, hence, she should record these products as: lithium chloride ( 2licl ) and oxygen ( 3o2 )   2 > 2 licl + 3o2.
