Which is the correctly balanced equation for the reaction of rust, Fe2O3, and hydrochloric acid, HCl? Fe2O3 + HCl → FeCl3 + H2O
Fe2O3 +3 HCl → 2 FeCl3 + H2O
Fe2O3 + 6 HCl → 2 FeCl3 + 3 H2O
Fe2O3 + 3 HCl → 2 FeCl3 + 3 H2O
.

step-by-step explanation:

i think it would be c

mark brainliest if im right

step-by-step explanation:

this "question" looks more like a project is there any other info you can give me about this. it could be too complex for someone else to do on this website

the given growth  function for the length of the fish (cm) is

f(m) = 5(1.07)m = 5.35m

where 

m = months

at the end of the study, the length is 9.19 cm. the  time for conducting the study is determined as

5.35m = 9.19

m = 1.7178 months

part a.

the study was performed over a time period  of about 1.72 months. therefore  the domain for  plotting the function is 0 < = m < = 1.72.

note:

if growth  continues at this rate for up to m months, then the domain would be 0< =m< =m.

part b.

the growth function is a linear function.

when m=0, f=0.

therefore the initial growth is zero, which represents the y-intercept.

part c.

assume that the growth function is valid for 0< =m< =9.

the average rate of change of the function is the slope of the linear function, which is 5.35 cm/month.
