Answer:
A compound
Explanation:
Sugar is a compound because it contains the atoms of three different elements in a fixed ratio (C:H:O = 12:22:11).
An <em>element</em> contains only one type of atom.
<em>Mixtures</em> and <em>solutions</em> can have variable compositions.
the answer is a chemical element
It contains monosacvharides, the simplest carbohydrate
Answer:
a. very acidic
Explanation:
A solution with a pH of 1.6 would be described as a very acidic solution.
The pH scale is a convenient scale for expressing the level of acidity or alkalinity of aqueous solutions.
The scale ranges from 1 to 14 in which case 1 is the lower limit and 14 the upper limit.
- An acidic solution has a pH value less than 7. As pH decreases, the acidity of the solution increases.
- Neutral solutions have a pH of 7
- An alkaline solution has a pH greater than 7 and the level of alkalinity increases as pH increases.
