There are many elements with a Latin name such as sodium, iron, potassium which all of their symbols refer to their Latin name, hope this helps.
The molecular formula for Hydrocarbon = C₄H₁₀
<h3>
Further explanation:</h3>
Given
50 ml hydrocarbon
200 ml CO₂
250 ml H₂O
Required
The molecular formula of Hydrocarbon
Solution
From Avogadro's hypothesis, at the same temperature and pressure, the ratio of gas volume will be equal to the ratio of gas moles
So moles Hydrocarbon : CO₂ : H₂O = 50 ml : 200 ml : 250 ml = 1 : 4 : 5
mol C in 1 mol CO₂=1, and for 4 moles CO₂ there are 4 moles C
mol H in 1 mol H₂O =2, and for 5 moles H₂O there are 10 moles H
So mol ratio C : H in compound = C₄H₁₀
Given :
Temperature, T = 55° C = ( 55 + 273 ) K = 328 K .
Volume of container, V = 28.9 dm³ = 0.0289 m³ .
Pressure, P = 144 kPa = 144000 Pa .
To Find :
Number of moles of nitrogen gas.
Solution :
We know, by ideal gas equation :
PV = nRT ( R ( universal gas constant ) = 8.31 J K⁻¹ mol⁻¹ .
Therefore, number of moles of nitrogen gas is 1.53 moles.
Answer:
Yes!
Explanation:
I think It would be fun!, Going thought space going from planet to planet. once i get back to earth i can make a document about my time in space.
