In the mixtures lab, you waited to see if the liquid would form lumpy or fluffy masses, which would indicate it was a a) suspension b) colloid c) homogeneous mixture d) solutionand explain!

B) colloid

Explanation:

Colloids, also called the colloidal system, is the term used to describe mixtures that look like a homogeneous solution, but are heterogeneous. It is not possible to realize that these mixtures are heterogeneous with the naked eye, for this reason, to find out if the solution is a colloid, the researcher must submit the substance to a process and wait to see if the liquid would form irregular or soft masses. Examples of colloids are: moisturizing cream, yogurt, milk, blood, paints and jam.

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day

attach the statements so i can answer : )
