Chapter 3 lecture readiness Assessment Part II Stoichiometry Model 1 2A + 3B + 5C 4D molecules A produces molecules c molecules B produces molecules C molecules A produces molecules D molecules B produces molecules D molecules A reacts with molecules B molecules are produced along with molecules D 1. What do the coefficients of a balanced equation represent? 2. If 6 molecules A are reacted, how many molecules D are formed? Explain as a group how you calculated this answer and show your work. 3. If 15 molecules B are reacted, how many molecules are formed? Make sure to show your work. 4. If 8 molecules of A are reacted, how many molecules B are used? Make sure to show the calculation.

Answer 1

2A + 3B 50+ 4D 2 molecides A produces 5 moleculer e 3 molecules 3 producen 5 moleculere 2 molecules A produces 4_ molecules D 3 molecules B produces 4 molecules D molecules At sieacts with 3 moleculer B 5 molecules @ are produced along with I 4 molecules D

1. The coefficients of a balanced chemical reaction represent the number of moles or molecules or atoms of the reactants involved and products formed.

2.
2A + 3 B > 50 + 4D - X 3 16A + 9B 15ct 12D Hence, 12 molecules of D are formed if - 6 molecules of Á are seated Just look for how much you have to multiply to make mo. of molecules of A = 6 . Here it is 9-3 je. if we the entire ean by '3' we will get the no. of a molecules of a 7 molecule D

3. Similoily as discussed in@, multiply equat - 2 5 Le 10 A + 15B - 25C + 20 D - ice, dlecul e tormed. Hence, as molecules of c are formed. 4. Multiply equ ① by 2 a 4 h. e. SA+12B - 200 + 16 D Hence, la molecules of B are used it 8 moleculer off are freacted.
