Answer:
Explanation:
Boyle believed that chemistry – the behavior of substances – could be explained through the motion of atoms, which in turn could be understood through mechanics – Galileo's mathematics of motion. Boyle was ultimately proved correct, because today we can understand chemistry mathematically, through quantum mechanics.
Answer:
2.50 g of AlCl3
Explanation:
Goodness, stoichiometry...
So, what we need to find first is the amount of grams of AlCl3. To do this we look at the formula of molarity.
M = mols/L of solvent
So we know two parts of this formula. We have the Molarity (0.150) and the mL (125).
Now, we can't forget that we must convert 125 mL into liters so we have 0.125 L ( I forgot and had to do the entire problem again...)
So if we do the backwards equation we get:
0.150 = x/0.125
If we do math (fun ikr) we get 18.75 mols of the solution.
Now, we have to plug this wonderful number into stoichiometry
<u>0.01875 mols | 133.5 g</u>
<u>| 1 mol AgCl3</u>
If you are unfamiliar with what I'm doing, I'm basically going to multiply 0.01875*133.5 then divide that whole thing by 1.
So, I got 2.503125 g AlCl3
If your teacher is a stickler for significant figures there are 3 sig figs for this problem so your final answer should be
2.50 g of AlCl3
Hope you have a great day and fun with chemistry!!!!
The difference between the plant and animal cells is in their structures, and this makes their functions to differ. Some organelles are present in the plant cell which are absent in the animal cell and vice versa. The presence/absence of these organelles impact the kind of functions that can be carried out by each cell.
- The plant cell has a rigid cell wall made of polysaccharides while the animal cell lacks cell wall. The cell wall serves supportive functions in the plant and gives it a shape. Animal cells are more or less round in shape.
- Plant cells have chloroplasts while it is absent in the animal cell. the chloroplast contains chlorophyll, a green pigment that is responsible to absorbing radiant energy, As such, the chloroplast enables plant cells to carry out photosynthesis. Animals cells cannot synthesize their own foods.
- Plant cells have large central vacuole that stores water and other contents while animal cells have small vacuole
- Animal cells have centrioles while plant cells do not. The centrioles make mitotic division different between the two cells, although, the same result is obtained at the end of the day.
