Calculate the mass of the bag of glass based on the weight (F) shown. The measurement from the scale is given in the caption (textbook page 8 picture next to question 6). This is what it says on caption: F=4.9 N Formula: m= F/a Formula: m= kg. m/s ^2 / 9.8 m/s^2 m= kg Type your answer *

i think 4.44 moles

fe 55.85 g/mol and h2o 18.02 g/mol.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
