The concentration of acetic acid in the vinegar is found to be 0.5857 M.
<u>Explanation:</u>
Here one mole of acetic acid is used to neutralize one mole of sodium hydroxide. According to the law of Volumetric analysis, we can write the equation as,
V1M1 = V2M2
V1 and M1 being the volume and molarity of NaOH
V2 and M2 being the volume and molarity of CH₃COOH
M2 = 
= 
= 0.5857 M
So the concentration of acetic acid in the vinegar is 0.5857 M.
Answer:
Explanation:
Mechanical energy = Gravitational potential energy + kinetic energy
Time Gravitational potential energy kinetic energy Total ME
0 4 0 4
2 2 2 4
4 0 4 4
6 2 2 4
8 4 0 4
and so on .....
We see that total mechanical energy is always 4 which is constant .
So gravitational and kinetic energy changes cyclically but total mechanical energy is constant .
Answer:
The functional group is called an amide. This is option C.
Explanation:
We see this is a three-carbon chain (a propyl chain), that ends with a double bond to oxygen and a single bond to an amine group (NH2). If the end carbon were only bound to the NH2 group and 2 hydrogen atoms, it would be an amine. If the end carbon only had a double bond to oxygen and a single bond to hydrogen, it would be an aldehyde. However, when a terminal carbon (a carbon at the end of a chain) has both a double bond to oxygen, and a single bond to an amine (NH2), it is called an amide.
We can also discount the answer thiol right away because those have a carbon-sulfur bond, and there is no sulfur in this molecule.
Is would be heat or light
Nitrogen is a gas because it is an airlike fluid substance which expands freely to fill any space available, irrespective of it's quantity
