Answer: 750ml
Explanation:
Using charle's law
V1/T1=V2/T2
V1= 500ml
T1= -73⁰C
V2= ?
T2=27⁰C
We can see that the temperature is in Celsius
Now,we will convert to Kelvin
Kelvin= 273+ Celsius
So convert the Celsius value to Kelvin
For T1= 273+(-73)
T1= 273-73
T1= 200K
For T2= 273+27
T2= 300K
V1/T1=V2/T2
500/200=V2/300
Cross multiply
200×V2=500×300
200V2= 150000
V2= 150000/200
V2= 750ml
So,
750ml of gas will occupy at 27⁰C
I would say that it sounds like you are an alchemist as during the 1500's at least they tried to turn base metals like Pb or lead into Au or gold. While this is not possible, their experiments gave rise to the science and techniques of metallurgy and assaying as confirmed by the great first mine geologist, Georgius Agricola in the 1500's,
Answer:The answer is simple. Nuclear fusion
Explanation
Where does sun gets its energy from to perform nuclear fusion?
The answer is simple. Nuclear fusion requires very high temperatures to occur. The sun is made of gasses, mostly hydrogen. When a gas is compressed adiabatically (without heat transfer) the temperature of the gas increases. (Incidentally, this is why Diesel engines don’t need spark plugs. The compression stroke causes the temperature of the fuel mixture to rise, causing ignition.) The increase in internal energy comes from work done on the gasses by gravity. In the process of formation of a star, like the sun, the mixture of gases of which it is composed is compressed due to gravity until it reaches a high enough temperature to produce fusion
Volume percentage is the percentage of volume of interested compound from the whole volume of the solution.
volume percentage of isopropyl alcohol can be calculated as follows;
volume percentage (v/v%) = volume of alcohol/ total volume of solution x 100%
total volume = 135 + 745 = 880 mL
substituting the values ,
v/v % of alcohol = 135 mL / 880 mL x 100 %
answer = 15.34 %
Answer:
Explanation:
Oleic acid originates from an unsaturated fatty acid with 18 carbon atoms and one double bond, which can be found in olive oil and many other vegetable and animal oils and fats. Its economic importance includes the production of soap making and cosmetics etc.
The line-bond structure of the given oleic acid in the question can be found in the attached below.
