What type of reaction is Al + 3CuSO4 --> Al2(SO4)3 + 3 Cu
laila [671]

It's a Single Replacement (or Displacement) Reaction because the equation follows the basic format for that type of reaction.

For Single Replacement Reactions, the general formula is:

AB + C = AC + B

So, if there's an element and compound on both sides of the equation, it's single replacement.

It is a hot summer day. You fill your glass with ice and pour in some sweet tea. What form of energy is found in the ice cubes?
vlabodo [156]
I think the form energy that is found in the ice cubes would be thermal energy. It <span> is the </span>energy<span> that comes from heat. Since all things tend to go towards equilibrium, the ice cubes dissipates heat to equilibriate with the environment.</span>

Which of the following pairs does not share the same empirical formula?
Svetradugi [14.3K]
PbCl2 and PbCl4

Empirical formula is when the molecular formula is reduced (each element) by the same number until you are unable to do so any further.
CH2O cannot be further reduced, but C3H6O3 can all be divided by 3 making it CH2O (same empirical formula)

Which of these things would you expect to have cells with both mitochondria
Allushta [10]

Answer:

D. Grass​

Explanation:

Every living organism must contain one or more cells to be considered "living". Each cell, however, contains certain structures that perform specific roles called ORGANELLES. These organelles are of different types and hence, perform different tasks. For example, mitochondria is the power house of a cell i.e. site of energy production, and hence, is found in every eukaryotic cell.

On the other hand, chloroplast is an organelle designed to perform photosynthesis, which only occurs in plant cells. Since only plant cells can undergo photosynthesis, only plant cells can contain chloroplast. Hence, according to this question, GRASS as a type of plant is an organism that will contain both mitochondria and chloroplast in its cells.
