Autotrophs are organisms that make their own food. Example: plants
From the stoichiometry of the reaction, the percentage yiled of the copper is 89.6%
<h3>What is reaction equation?</h3>
The reaction equation here is given as; Fe(s) + CuSO4 (aq) ----->FeSO4(aq) + Cu(s)
Number of moles of Fe = 0.9845 g/56 g/mol = 0.018 moles. Since the reaction is 1:1, this is also the number of moles of Cu formed.
Theoretical yiled of Cu = 0.018 moles * 63.5 g/mol = 1.143 g
Percentage yiled = 1.024 g/1.143 g * 100/1 = 89.6%
If 1 mole of Fe contains 6.02 * 10^23 molecules
0.018 moles of Fe contains 0.018 moles * 6.02 * 10^23 molecules/1 mole = 1.1 * 10^22 molecules.
Number of moles of AgNO3 = 1.35 g/170 g/mol = 0.0079 moles
Molarity of the solution = 0.0079 moles/250 * 10^-3 L = 0.0032 M
Hence; 0.0032 M * V1 = 100 mL * 0.01 M
V1 = 312.5 mL

Answer:
21.4666666667 g/cm^3
Explanation:
The density of a substance can be found by dividing the mass by the volume.
d=m/v
The mass of the sample is 16.1 grams and the volume is 0.75 cubic centimeters.
m= 16.1 g
v=0.75 cm^3
Substitute the values into the formula.
d=16.1 g / 0.75 cm^3
Divide
d= 21.4666666667 g/cm^3
The density of platinum is 21.4666666667 grams per cubic centimeter.
In order to retrieve the soluble salt from the solution, crystallization must be carried out.<span />
Electrons are the subatomic particles with the smallest mass.
Neutrons have no charge and protons have a positive charge, both of their masses are equal. Electrons have a negative charge and have the least mass.
