The peak at 1620-1680 cm⁻¹ is characteristic absorption peak of C=C stretching while peak at 3010-3100 cm⁻¹ is characteristic absorption peak of C-H streching in which C is sp² hybridized.
It means that the structure contains carbon double bond carbon but there is no H attached to sp² hybridized carbon.
I have drawn one structure which follows the scenario. And molecular formula of Molecule is
C₆H₉N.
Result: According to given information the best suggested compound has formula
C₆H₉N with structure shown below,
Answer:
0.373M
Explanation:
Given parameters:
Mass of NaOH given = 112g
Volume of solvent = 0.75L
Solution:
1....To solve this problem, we first find the number of moles of the solute using the expression below:
Number of moles = mass/molar mass
Solving:
Molar mass of NaOH
Atomic mass of Na = 23g
Atomic mass of O = 16g
Atomic mass of H = 1g
Molar mass = 23 + 16 + 1 = 40g/mol
Number of moles = 112/40 = 2.8mol
2..... From the number of moles of solute, we then evaluate the molarity of the solution that would be produced using the expression below:
Molarity = number of moles/Volume
Molarity = 2.8/0.75 = 0.373M
'Acceleration' means any change in speed or direction
of motion.
so
C). No acceleration. Straight, at constant speed.
No change of speed or direction.
Answer:
A voltaic cell
Explanation:
A voltaic cell is a device which converts chemical energy to electrical energy. The chemical reactions that take place inside the cell causes electrons to flow from anode to cathode hence, electricity is produced. A simple voltaic cell is made by placing two different metals in contact with an electrolyte separated by a salt bridge. The cathode is the negative electrode while the anode is the positive electrode. It is also called a galvanic cell.
In a voltaic cell having a copper/copper solution half cell, reduction occurs at the cathode. Hence, at the cathode copper II ions accept two electrons and become reduced to ordinary metallic copper. This causes the blue colour of the solution to become discharged (fade) as the cell continues to function.
When the temperature increases,the particles will conduct successful collisions and the rate of reaction will also increase
