Question

which of the following is an example of a homogeneous mixture?
mcdonalds sweet tea
water (h2o)
nitrogen
pepperoni and sausage pizza.

Explanation:

A homogeneous mixture has a uniform composition throughout. McDonalds Sweet Tea is a mixture of tea, sugar, water and other flavor - compounds and appears uniform. Water ($H_2O$) is a compound, not a mixture. Nitrogen is an element, not a mixture. A pepperoni and sausage pizza is a heterogeneous mixture as you can see the different components (pepperoni, sausage, cheese, crust).

Answer:

McDonalds Sweet Tea
