45:06 What most likely occurred during this demonstration? In a science demonstration, a teacher mixed zinc (Zn) with hydrogen chloride (HCI) in a flask and quickly attached a balloon over the mouth of the flask. Bubbles formed in the solution and the balloon inflated. O The Zn and HCl both retained their identity. O Either Zn or HCI, but not both, retained its identity. Evaporation of one of the substances occurred. O One or more new substances formed. Mark this and return Save and Exit Next Submit

One or more new substances formed.

Explanation:

This is an example of a chemical property because bubbles formed, and the mixture produced a gas which allowed the balloon to inflate. The production of bubbles is an indicator of a chemical change. When a chemical change occurs, one or more new substances form as a result.

- I took the quiz and got 100%

Hope this helps!

explanation:

crosscutting concepts have application across all domains of science. as such, they are a way of linking the different domains of science. they include patterns; cause and effect; scale, proportion, and quantity; systems and system models; energy and matter; structure and function; and stability and change.
