Explanation:
The observation of student was that thermometer reading changed from 27°C to 35°C which indicates that temperature of the beaker solution rose after reaction due to release of heat during reaction as a product.
Those chemical reactions which gives heat energy as a product into their surrounding are categorized as exothermic reactions. During the course of these reaction temperature of the surroundings also increased.
So, this means that reaction between silver nitrate and copper wire is an exothermic reaction.
Three ways that the student could speed up the reaction :
- By adding catalyst to the reaction.
- By decreasing the temperature.
- By increasing the concentration of silver nitarte solution.
Explanation:
Since the wheel moves up and down, the position that represents the potential energy is that which has the maximum height from the ground.
Potential energy is the energy at rest of a body.
It is given as:
Potential energy = m x g x h
m is the mass of the body
g is the acceleration due to gravity
h is the height of the body
We can see that mass and height are directly related to the potential energy a body exerts.
The higher the wheel from ground, the higher its potential energy.

Answer:
4.00 moles
Explanation:
Avogadro´s number is 6.022 x 10²³ molecules, atoms, particles, etc.
Here we are talking of atoms of copper, so 1 mol of copper is equal to 6.022 x 10²³ atoms, and we only need to setup the proportion to find the number of mol in 2.41 x 10²⁴ atoms. ( Think of it like a dozen, avogadro´s is 6.022 x 10²³ )
( 1 mol copper/ 6.022 x 10²³ atoms of copper ) x 2.41 x 10²⁴ atoms
= 4.00 moles
Answer:
The answer is given below
Explanation:
- β oxidation of stearoyl-CoA------------ 8 FAD reduced
- β oxidation of oleoyl-CoA -------------- 1- 7 FAD reduced and 2- reduced requires δ3,δ2-enoyl-CoA isomerase required for completion of round 4
- in Both ----------- 1- 9 acetyl-CoA produced, 2- 8 NAD+ reduced and 3- β oxidation completed in 8 rounds
