Answer:
400 meters every 20 seconds
Explanation:
First. let's write the reaction formula: HBr +LiOH ----> LiBr + H₂O
let's get the moles of LiOH first
moles= Molarity x Liters
moles= 0.253 M x 0.01673 Liter= 0.00423 moles LiOH
using the balanced equation, you can see that 1 mol LiOH is equal to 1 mol HBr. so:
0.00423 mol LiOH = 0.00423 mol HBr
now let's find the concentration
molarity= mol/ Liters
0.00423 mol/ 0.01000 Liters= 0.423 M
Running water. Streams, lakes, rivers, ponds, oceans- all affect the Earth's landscape.
When multiplying and deviding follow the least number of sf.
since wavelength = 1/period
hence wavelength=1/2.7
=0.37 (2sf)
