Substances [tex]$A$[/tex] and [tex]$B$[/tex] react in a ratio of [tex]$A + B \rightarrow AB$[/tex]. Colin was combining substance [tex]$A$[/tex] and substance [tex]$B$[/tex] to form substance [tex]$AB$[/tex]. He added 10 g of substance [tex]$A$[/tex] and 45 g of substance [tex]$B$[/tex].

How much of substance [tex]$AB$[/tex] would Colin make?

A. 10 g
B. 35 g
C. 45 g
D. 55 g


Sagot :

Let's address the problem step by step:

1. Identify the reaction:
The reaction given is [tex]\( A + B \rightarrow AB \)[/tex]. This indicates that one unit of substance [tex]\( A \)[/tex] reacts with one unit of substance [tex]\( B \)[/tex] to produce one unit of substance [tex]\( AB \)[/tex]. This is a 1:1 ratio.

2. Amounts of substances combined:
Colin added 10 grams of substance [tex]\( A \)[/tex] and 45 grams of substance [tex]\( B \)[/tex].

3. Determine total mass:
Since the reaction is in a 1:1 ratio, all of the given substances [tex]\( A \)[/tex] and [tex]\( B \)[/tex] will combine to form [tex]\( AB \)[/tex], without any excess. Thus, we need to calculate the total mass of the newly formed substance [tex]\( AB \)[/tex].

4. Calculate total mass of [tex]\( AB \)[/tex]:
The mass of [tex]\( AB \)[/tex] formed will be the sum of the masses of substance [tex]\( A \)[/tex] and substance [tex]\( B \)[/tex].

[tex]\[ \text{Total mass of } AB = \text{Mass of } A + \text{Mass of } B \][/tex]

Substituting the given values:

[tex]\[ \text{Total mass of } AB = 10 \text{ g} + 45 \text{ g} = 55 \text{ g} \][/tex]

Therefore, Colin would make [tex]\( 55 \)[/tex] grams of substance [tex]\( AB \)[/tex].

The correct answer is:
[tex]\[ \boxed{55 \text{ g}} \][/tex]
