Answer:
nitrogen is the answer because of the same position of group in periodic table
Answer: There are
moles
present in
particles.
Explanation:
According to the mole concept, 1 mole of a substance contains
particles.
Hence, number of moles present in
particles are calculated as follows.
No. of moles =
mol
=
mol
Thus, there are
moles
present in
particles.
Answer:
Explanation:
Exothermic: the surrounds feel warmer. A wood fire stove is a good example of an exothermic reaction. You can feel the heat on your hands. It's exothermic.
Endothermic is exactly the opposite. The reaction takes place, but the heat comes from the surroundings. When you touch something that goes through an endothermic reaction, it feels much cooler.
This reaction, just by definition is endothermic.
Answer:
Saponification is a process of mixing triglycerides with potassium hydroxide (lye) in order to produce fatty acid and glycerol also known as soap.
During this experiment, many errors can occurs which are following;
- Incorrect measurement of both the salts that combine to form soap.
- The beaker and the stirrer has residue of some other chemical that gets mixed with two components and reacts.
- The two products are not mixed well or not long enough to reach the end product.
- The temperature is not favorable.
- The resting period is not calculated properly
I hope the answer is helpful.
2 C₁₇H₁₉NO₃ + H₂SO₄ → Product
Moles of H₂SO₄ = M x V(liters) = 0.0116 x 8.91/1000 = 1.033 x 10⁻⁴ mole
moles of morphine = 2 x moles of H₂SO₄ = 2.066 x 10⁻⁴
Mass of morphine = moles x molar mass of morphine = 2.066 x 10⁻⁴ x 285.34
= 0.059 g
percent morphine =

=

= 8.6 %
