Nio conducts a science experiment. he puts yeast into a bottle with water and sugar, and then caps the bottle with a balloon. he returns two hours later and notices there are bubbles on the surface of the mixture in the bottle and that the balloon has inflated, but there are no other apparent changes. what most likely happened? a non-chemical change, because there are no indicators of chemical changes taking place a chemical change, because the mixture changed color a chemical change, because a gas was produced a non-chemical change, because the changes that occurred are reversible

Answer

Hi,

The correct answer option is {C} A chemical change because a gas was produced.

Explanation

In this experiment, the yeast acts on the sugar to produce carbon dioxide gas that fills the bottle and then the balloon. This process is called fermentation. Chemical changes occur in the bottle, were the sugar is turned to alcohol, carbon dioxide and energy. This is possible because yeast produces an enzyme maltase responsible for glucose formation which can ferment.

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.
