Question

Not a timed or graded assessment. Quick answer will receive amazing review. Will need to be shown exactly how I should put in my answer.

Answer 1

`1CF_4+2Br_2\rightarrow1\text{CBr}_4+2F_2`

Explanations:

Given the unbalanced chemical reaction:

`aCF_4+bBr_2\rightarrow cCBr_4+dF_2`

You need to determine the values of the constants a, b, c, and d that will balance the chemical reaction.

Note that to balance the reaction, the number of moles of elements on both sides of the reaction must be equal.

For Carbon elements:

a = c

For Flourine element:

4a = 2d

2a = d

For Bromine element:

2b = 4c

b = 2c

Recall that a = c, therefore, b = 2a

Replace c = a, b = 2a and d = 2a into the reaction to have:

`\begin{gathered} \cancel{a}CF_4+2\cancel{a}Br_2\rightarrow\cancel{a}CBr_4+2\cancel{a}F_2 \\ 1CF_4+2Br_2\rightarrow1\text{CBr}_4+2F_2 \end{gathered}`

This gives the balanced equation for the chemical reaction.
