Answer:
0.167
Explanation:
Molar mass of NaOH = 40
40 g of NaOH = 1 mole
5 g of NaOH = 0.125 moles
1000 ml = 1 L
750 ml = 0.75 L
Molarity = 0.125 / 0.75 = 0.1666
Approximately = 0.167
Answer:I think it’s material chemistry
Explanation:
Two hydrogens are bonded with nitrogen
Chlorine is bonded with nitrogen
Because nitrogen has 5 valence electrons, and it has only used 3 electrons for bonding with chlorine and hydrogen, there is one pair of electrons left.
Answer:
ITS B
Explanation:
MY CONSCIOUS MIND IS TELLING ME
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: .
