Answer:
ethene
Explanation:
The chemical compound acetylene (systematic name: ethyne) has the formula C2H2. It's a hydrocarbon and the most basic alkyne. Because its two carbon atoms are linked together in a triple bond, acetylene is unsaturated as an alkyne.And the ending of acetylene has ene which indicates that it's an alkene .And the ending of acetylene has ene which indicates that it's an alkene.
The volume of 0. 250 mole sample of gas occupy if it had a pressure of 1. 70 atm and a temperature of 35 °C is 3.71 L.
Calculation,
According to ideal gas equation which is known as ideal gas law,
PV =n RT
- P is the pressure of the hydrogen gas = 1.7 atm
- Vis the volume of the hydrogen gas = ?
- n is the number of the hydrogen gas = 0.25 mole
- R is the universal gas constant = 0.082 atm L/mole K
- T is the temperature of the sample = 35°C = 35 + 273 = 308 K
By putting all the values of the given data like pressure temperature universal gas constant and number of moles in equation (i) we get ,
1.7 atm×V = 0.25 mole ×0.082 × 208 K
V = 0.25 mole ×0.082atm L /mole K × 308 K /1.7 atm
V = 3.71 L
So, volume of the sample of the hydrogen gas occupy is 3.71 L.
