Answer:
c) 30
Explanation:
In an atom , the relation between the subatomic particles of the atom are given as follows -
For a neutral atom ,
Atomic number = number of protons = number of electrons ,
Mass number = number of protons + number of neutrons,
Hence , from the given information of the question,
Atomic number of Manganese = 25 ,
mass number of Manganese = 55 ,
Now, to calculate the number of neutrons , the above relation can be used -
Mass number = number of protons + number of neutrons,
Rearranging ,
number of neutrons = Mass number - number of protons
substituting the respective values ,
number of neutrons = 55 - 25 = 30 .
Angular Velocity is the answer
P1* V1 = P2 * V2
100* 5 = 50 * V2
500 = 50 V2
V2 = 500 / 50
V2 = 10.0 L
hope this helps!
Partial pressure is the pressure that would be exerted by one of the gases in a mixture if it occupied the same volume on its own. For a mixture of gases, each gas has a partial pressure which is the hypothetical pressure of that gas if it alone occupied the volume of the mixture at the same temperature.
Since the structures are not given, I'll just provide the structure for these functional groups.
Alkane: You know the compound is an alkane if it conforms to the general formula CₓH₂ₓ₊₂, where x is any positive integer.
Alcohol: A compound is an alcohol if the compound contains an -OH functional group.
Carboxylic acid: The general formula for carboxylic acid is RC=OOH. The R is any hydrocarbon chain. The C atom is attached to one oxygen atom by a double bond, and one O atom by a single bond.
