Question

question 3 (1 point) listen which of the following is a homogenous mixture? check all that apply 1) solution of sugar dissolved 2) excess salt in water, more than what can dissolve 3) a cup of black coffee 4) pizza with all its toppings 5) water from a local pond, with things floating in it, and things dissolved in it

Explanation:

A homogeneous mixture has a uniform composition throughout. A sugar - dissolved solution is uniform as sugar molecules are evenly dispersed in water. Black coffee is also a homogeneous mixture as the coffee compounds are uniformly mixed in water. Excess salt in water (more than what can dissolve) has undissolved salt, making it heterogeneous. A pizza with toppings has different components like cheese, sauce, and toppings which are not uniformly distributed, so it's heterogeneous. Pond water with floating and dissolved things is also heterogeneous due to the non - uniform distribution of substances.

Answer:

1. Solution of sugar dissolved
2. A cup of black coffee
