Answer:
1.19 g
Explanation:
Given that:
Molecular weight of diene 136 g/mol
Molecular weight of Maleic Anhydride 96 g/mol
Mass of crude diene = 2.5 g
Percent of Composition for Peak A = 66%
Percent of Composition for Peak B = 22.66%
Percent of Composition for Peak C = 11.33%
Let us determine the amount of diene in the sample;
So, using to represent the amount of diene; we have :
=
=
= 1.65 g
Using the limiting reagent equation to determine the amount of Maleic Anhydride
=
=
= 1.19 g
The grams of Maleic Anhydride used to react with 2.5 g sample of crude diene = 1.19 g
Not sure what the question is, but a standard sodium atom has 11 protons, 11 electrons, and 12 neutrons with an atomic mass of 23. A sodium atom with a mass number of 24 probably has 13 neutrons.
I think B. because of this picture??
Answer:
False
Explanation:
When electrons move from lower to higher electron energy level they absorb the energy. When they move from higher to lower energy level they emit energy.
Answer:
- <u><em>Sodium fluoride</em></u>
Explanation:
A <em>solution </em>is constituted by two parts: the solute and the solvent (there may be more than 1 solute and more than 1 solvent, but that is not the key of the answer).
<em>Solute</em> is the substace that is dissolved and it is in less amount than the solvent.
<em>Solvent</em> is the substance that can dissolve the solute and it is a greater amount than the solute.
In the given solution:
- <em>sodium fluoride</em>, <em>85.0 mL</em>, is the solute,
- <em>water</em>, <em>350.0 mL</em> is the solvent, and
- the mixture of both substances is the solution.
