at equilibrium.
<h3>Explanation</h3>
Concentration for each of the species:
There was no Y to start with; its concentration could only have increased. Let the change in be .
Make a table.
Two moles of X will be produced and two moles of Z consumed for every one mole of Y produced. As a result, the <em>change</em> in will be and the <em>change</em> in will be .
.
Add the value in the C row to the I row:
.
What's the equation of for this reaction? Raise the concentration of each species to its coefficient. Products go to the numerator and reactants are on the denominator.
.
. As a result,
.
.
The degree of this polynomial is three. Plot the equation on a graph and look for any zeros. There's only one zero at . All three concentrations end up greater than zero.
Hence the equilibrium concentration of Y: .
Answer:
3.98 g
Explanation:
Step 1. Write the balanced chemical reaction. In this case, magnesium reacts with oxygen to produce magnesium oxide:
\\
Step 2. Calculate the number of moles of magnesium:
\\
Step 3. Calculate the number of moles of oxygen:
\\
Step 4. Identify the limiting reactant comparing the equivalents. Equivalent of Mg:
Equivalent of oxygen:
Therefore, Mg is the limiting reactant.
\\
Step 5. According to the stoichiometry of this reaction:
\\
Step 6. Convert the number of moles of MgO into mass:
Calculate the mass defect and nuclear binding energy of an atom ... To convert to joules per nucleon, simply divide by the number of nucleons.
Answer:
113
Explanation:
We are given that the atom of cadmium has 66 neutrons:
Number of neutrons in Cd = 66
Now;
Mass number = ?
The mass number of an element is the sum of the number of protons and number of neutrons
Mass number = number of protons + number of neutrons
By the position of cadmium, it has an atomic number of 47 and this is the number of protons
Mass number = 47 + 66 = 113
The three patters are clumped, random, and uniform
