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.
Answer:
Single-replacement reaction
Explanation:
Single-replacement reactions, aka. single-displacement reactions, involve one element/ion in a compound being replaced by another element/ion. In this case, aluminum is replacing the iron in the compound.
If you need help visualizing, the equation looks like this:
Fe₂O₃ + Al³⁺ --> Al₂O₃ + Fe³⁺
Answer:
Explanation:
The rate of the forward reaction is less than the rate of the reverse reaction. ... The reaction rates of the forward and reverse reactions are equal
The cell wall is mixed with the cell membrane, the cell wall is outside of the membrane and the cell membrane is letter i which allows materials to pass in and out of the cell.
Chloroplasts are letter k they basically just help the plant use photosynthesis.
cell wall: f
chloroplasts: k
