Answer:
Water is a solvent, and CO2 gas and the powdered drink mix are both solutes.
Explanation:
In order to successfully answer this question, we need to remember that solutions consist of solutes and solvents.
Solutes are components of solutions that are dissolved (typically ionic salts if we have a polar solvent), while solvents are fluids (usually liquids) that provide a medium for the solutes to dissolve (water is the most common polar solvent for ionic salts, for example).
As a general rule, solvent is used in great excess, that is, it makes the greatest percentage in terms of mass of a particular solution.
Applying the theory above for this problem, notice that the greatest percentage of this solution belongs to water, besides, water is a common solvent in general. Thus, it is our solvent.
Also, solution would only have one solvent and one or several solutes. This leaves the two other components, carbon dioxide and powdered drink mix, as our solutes, as they have a lower percentage than our solvent.

Explanation:
Resonance is a valence bond terminology which is used to describe a situation in which a single structure is not able to fully describe the nature of bonding in a molecule.
In such cases, we invoke more than one structure. Each structure contributes significantly to our understanding of the nature of bonding in the molecule under consideration and these structures are called canonical or resonance structures.
The real structure of the molecule is somewhere in between these structures - a resonance hybrid.
For ozone, two equivalent structures can be used to describe the bonding in the molecule. These structures are equivalent as shown in the mage attached. We can see from these structures that the bond order in ozone is 1.5(one and half bonds)
Answer:
When metals react they lose electrons.
Explanation:
An ion is defined as a molecule or atom made up of a different number of electrons and protons. This makes the electric charge of the molecule net, not neutral.
In other words, an ion is a molecule or atom that has a positive or negative electric charge, making it an atom whose electric charge is not neutral.
The characteristic property of a metallic atom is to lose one or more of its electrons to form a positive ion. That is, metals lose electrons and acquire a net positive charge, which is why they are electropositive.
