Answer:
2.67g Ni
Explanation:
To convert from moles to mass, use molar mass as a conversion factor.
Nickel has a molar mass of 58.69g/mol.
0.0455mol () = 2.67g Ni
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 question was to be what is metal in modern periodic table?. Thank for understanding.
Now we come to business:
Metal in modern periodic table:is all the elements to the left of the line.
Explanation:
- if you look at the modern periodic table diagram you will see a stair-stepped line starting at Boron(B),atomic number 5,and going all the way down to Polonium(Po), atomic number 84.Except for Germanium(Ge)and Antimony(Sb),all the elements to the left of the line can be classified as metals.
All of the elements in a period have the same number of atomic orbitals. For example, every element in the top row (the first period) has one orbital for its electrons. All of the elements in the second row (the second period) have two orbitals for their electrons. As you move down the table, every row adds an orbital.
