A given hydrocarbon is converted completely to carbon dioxide and water, and equal numbers of moles of co2 and h2o are produced.

Sauron [17]

X moles of CO₂, and x moles of H₂O

CxH2x + 3x/2 O₂ -------> xCO₂ + xH₂O

CxH2x or CnH2n ----> ALKENE ( hydrocarbon with double bond)

Given the balanced equation representing a reaction: H2 → H + H What occurs during this reaction? 1. Energy is absorbed as bonds

RoseWind [281]

Answer : The correct option is, (2) Energy is absorbed as bonds are broken.

Explanation :

As we know that the bonds are formed and breaks during the chemical reaction. Some energy is released or absorbed when the bonds are formed and breaks during the chemical reaction.

During the bond breaking, some energy is required to break the bonds.

During the bond formation, some energy is released to the formation of the bonds.

In the given reaction, the bond between the hydrogen-hydrogen in $H_2$ are breaking into two hydrogen. That means during the bond breaking, some energy is required or absorbed to break the bonds.

Hence, the correct option is, (2) Energy is absorbed as bonds are broken.

Describe what occurs at mid-ocean ridges?

Tanya [424]

<span>A mid-ocean ridge is a mountain rage under the water. It is formed due to plate tectonics. The shifting of the plates lifts up the floor of the ocean. When convection currents happen they raise the mantle that is located beneath the oceans crust and it creates magma where the two tectonic plates meet.</span>
