Answer:H2+Br2-->2HBr
Step-by-step explanation:
The amount of atoms on the left side must be equal to the amount of atoms on the right side for each element.
On the left you got 2xH and 2xBr.
This means you must have the same amount on the right.
2HBr =2xH + 2xBr
The y-intercept = 127 and the slope = -10
<h3>How to determine the y-intercept and the slope?</h3>
The function is given as:
y = 127 - 10x
A linear function is represented as:
y = c + mx
Where
c = the y-intercept
m = slope
This means that:
y-intercept = 127
slope = -10
The y-intercept implies that, the initial amount of water is 127 ounces and the slope implies that the water leaks by 10 ounces per minute
