Answer:
Pressure=3.91atm
Explanation:
As given in the question that gas is ideal so
we can use Ideal gas equation
volume of gas is not given directly but volume of container is given and we know gas takes the volume in which they are kept.
therefore mole remains contant
P1=2.5 atm
V1=2L
T1=320K
P1=?
V1=1L
T1=250K
..............(1)
................(2)
eqn2/eqn1
Pressure=3.91atm
Answer:
A
Explanation:
water molecules are combined to make food
Answer:
4th Option
Explanation:
HNO3 is an acid, KOH is a base and they react to produce KNO3 which is a salt and H2O water.
So this reaction is a neutralisation reaction.
When two compounds have same molecular formula but different structural formula, they are said to be
isomers of each other and this phenomenon is called as
isomerism.
Hexane has
six isomers.
The isomers of hexane have a difference in their structure due to parent chain length (
chain isomerism). They are also differentiated on the basis of straight chain as in n-hexane and branched chain as in remaining five. Structures along with names are shown below.
