Answer:
60.42 grams
Explanation:
So, neon has a molar mass of 20.18 g/mol , which means that every mole of neon has a mass of 20.18 g so that means three of them is 60.42 grams

Answer:
In a chemical reaction, chemical equilibrium is the state in which the forward reaction rate and the reverse reaction rate are equal. The result of this equilibrium is that the concentrations of the reactants and the products do not change.
Explanation:
Answer:
Explanation:
The perfect illustration for the Table is shown below:
Generic Reactions Reactants Products Transition state
Synthesis
A + B → AB A+B = -15 kJ AB = 20 kJ 30 kJ
Single
Replacement
C + AB → CB + A C + AB = 65 kJ CB + A = 30 kJ 85 kJ
Double
Replacement
AB+CD → AD+CB AB+CD = 10 kJ AD+CB = 60 kJ 70 kJ
We are tasked to create the potential energy diagrams for each of the three chemical reactions.Then, analyze the data and your diagrams for each reaction.
TO ANSWER THAT ; I HAVE CAREFULLY DRAWN THE POTENTIAL ENERGY DIAGRAMS FOR THE THREE CHEMICAL REACTIONS & THE ANALYSIS FOR EACH ARE SHOWN IN THE DIAGRAMS ATTACHED BELOW .
NOW; over to the total change in enthalpy and the activation energy: Using the energy values provided for each reaction is : we can see the calculation of the total change in enthalpy and the activation energy in the diagram as well by using the energy values provided for each reaction.
Activation Energy Enthalpy change
Synthesis reaction 45 kJ + 35 kJ
Single replacement 20 kJ - 35 kJ
reaction
Double replacement 65 kJ + 50 kJ
Answer : The partial pressure of is 102.3 mmHg.
Explanation :
As per question,
Mass of = 62.9 g
Mass of = 33.2 g
Molar mass of = 18 g/mole
Molar mass of = 62 g/mole
First we have to calculate the moles of and .
Now we have to calculate the mole fraction of and .
Now we have to partial pressure of .
According to the Raoult's law,
where,
= partial pressure of water vapor
= total pressure of gas
= mole fraction of water vapor
Therefore, the partial pressure of is 102.3 mmHg.
Hey there!:
β-decay:
Unstable nucleus undergo β-decay in which a neutron is converted into proton , so
¹₀ n ----> ₁¹p + ₋₁⁰e ( Z + 1 )
The complete reaction is as follows:
²²⁷₈₉AC -----> ²²⁷₉₀ Th + ₋₁⁰e
Therefore , the daughter nucleus is : ²²⁷₉₀ Th
Hope that helps!
