substances a and b react in a ratio of a + b → ab. colin was combining substance a and substance b to form substance ab. he added 10 g of substance a and 45 g of substance b. how much of substance ab would colin make? 10 g 35 g 45 g 55 g
Answer
Explanation:
Step1: Identify reaction principle
The reaction is $A + B\rightarrow AB$. Mass is conserved in a chemical - reaction.
Step2: Calculate mass of product
The mass of $AB$ formed is the sum of the masses of $A$ and $B$ that react. Given $m_A = 10g$ and $m_B=45g$. Then $m_{AB}=m_A + m_B$. $m_{AB}=10g + 45g=55g$
Answer:
55 g
