Answer:
Density = 2.137 gram per liter (Approx.)
Explanation:
Given:
Gaseous fuel Butane C4H10
Pressure = 0.897 atm
Temperature = 24°C = 24 + 273 = 297 k
Find:
Density of butane gas
Computation:
We know that molar mass of butane = 58.12 g/mol
Density = [molar mass x pressure] / Rt
Density = [58.12 x 0.897] / [0.0821 x 297]
Density = [52.13] / [24.3837]
Density = 2.137 gram per liter (Approx.)
The reaction is actually endothermic because delta H is positive, indicating that it absorbing heat.
Answer:
24 hours
Explanation:
There are 24 hours in a day cause that is how long for the earth to spin on its axis
Answer:
Yes
Explanation:
Certain electrons can indeed, be shared. <u>The only electrons that can be shared between atoms are valence electrons</u>. The reason being is because they are the outer most electrons which are unpaired. You wouldn't want to remove any electrons from paired orbitals. The unpaired electrons seek to be paired, thereby making the element more stable. Your outer most electrons are called <em>valence electrons.</em>
