The more work someone does, the more energy they need. For example, if someone is moving a large couch they are going to use a lot of energy because it is heavy. However, if the couch was smaller, they would be using less energy because it does not weigh as much as they will not become as tired!
Answer:
(a) OPTION E=4
b) option E C sp² + C p
Explanation:
DEGREE OF UNSATURATION = C -H/2 -X/2 +N/2 +1
X IS HALOGENS
5-5/2+1/2+1= 4
b) Ethene comprises of two sp2-hybridized carbon atoms (bound to each other by sigma and two atoms each with hydrogen). The remaining unhybridized carbon p orbitals form a pi bond, giving ethene reactivity
The principal ingredient of glass is quartz sand (SiO₂).
