Answer:
The correct answer is - directly; Avogadro’s.
Explanation:
At the same temperature and pressure, gases of the same or equal volume have the same number of molecules. The relation between the moles of the gases and the volume of the gases are indirectly proportional to one another at the same temperature and pressure. This law is called Avogadro's law. In the case of an ideal gas of a particular mass has the volume and moles are directly proportional.
Thus, the correct answer is - directly; Avogadro’s.
Answer:
the answer should be c
Explanation: why because 37/19 k toward 0+1e +37/18 AR is equivalent to the beta decay and it describes the best beta decay in the formula.
North Pole ,land is the answer
Answer:
Dissociation NH3 0.10 M : 1.2%
Dissociation NH3 0.010 M : 3.9%
Dissociation CH3NH2 0.10 M : 6.5%
Explanation:
Hello!
To calculate the percentage of dissociation it is necessary:
Pose the balanced chemical equation.
Pose the equilibrium constant.
Calculate the value of "x"
Calculate the percentage of dissociation.
By having the concentrations given two significant figures we express the dissociations with the same amount of significant figures.

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
