Answer:

Explanation:
Let's call the unknown compound X.
1. Calculate the mass of each element in 1.23383 g of X.
(a) Mass of C

(b) Mass of H

(c)Mass of Fe
(i)In 0.4131g of X

(ii) In 1.2383 g of X

(d)Mass of O
Mass of O = 1.2383 - 0.632 07 - 0.074 157 - 0.195 67 = 0.336 40 g
2. Calculate the moles of each element

3. Calculate the molar ratios
Divide all moles by the smallest number of moles.

4. Round the ratios to the nearest integer
C:H:O:Fe = 15:21:1:6
5. Write the empirical formula

Answer:
A) Concentration
Explanation:
When you add a chemical to itself it becomes more concentrated making it more powerful and faster
Answer:
Down below
Explanation:
The following uses nickel(II) chloride
2AgNO3(aq) + NiCl2(aq) ==> Ni(NO3)2(aq) + 2AgCl(s) Molecular
The cell will not store food, water, nutrients, and waste.
Explanation:
In the absence of a vacuole in a cell, the cell will not be able to store food, water, nutrients and its wastes.
The vacuole provides a storage medium for the products in the cell. It is a very important cell structure.
They store food and are both found in both plant and animal cells
*Genetic information are transmitted by the nucleus
* Energy is produced in the mitochondria
* Photosynthesis takes place using the chloroplast
