Hi!
Fuel-cell cars only release water and heat in the atmosphere.
Since they are only run by oxygen and hydrogen to produce electricity in the motor, they don't emit carbon dioxide or greenhouse gas as what other people think.
Basically, automotive engineers and scientist classified them as zero-emission.
Inner core: Iron and nickel
Outer core: Molten iron and nickel
Mantle: Magnesium and iron
Crust: Silicon, magnesium, iron, aluminium, oxygen, etc.
The formula for speed is
s=distance/time
Substitute
s=1000m/250 sec
Divide
s=4 m/s
Hope this helps you
Answer:
The name of the molecule which is given below is 2-pentene.
Explanation:
Alkenes are the organic compounds which are composed of carbon and hydrogen atoms, in which double bond is present.
In the given diagram:
Each corner and joints shows the carbon atoms and number of carbon atoms in it is 5.
One double bond is present in the 2nd position.
So the compound is 2 pentene.
Hence, 2 pentene is the name of the compound.
