Cells are the basic building blocks of all living things
The reaction is:
C₂H₄ + 3O₂ → 2CO₂ + 2H₂O; ΔH = 1410 kJ
When we reverse this reaction, the sign of the enthalpy change, ΔH, will be changed. The enthalpy change for the reversed reaction would be 1,410 kJ.
Next, we must also multiply the reaction by 2, so the final enthalpy change for the reverse reaction will be:
ΔH = 2,820 kJ
Ferns reproduce with spores which existed the longest in Earth history.
Gymnosperms reproduce with cones and has needle-like, waxy leaves.
Angiosperms reproduce with flowers and newest type of plant in Earth history.
<h3>How ferns, gymnosperm and angiosperm reproduce?</h3>
Ferns reproduce with spores that existed the longest in Earth, gymnosperms reproduce through the formation of cones having needle-like, waxy leaves whereas angiosperms reproduce with flowers which turns into seed. The newest type of plant in Earth history is also belongs to this group.

Explanation:
dry wooden spoon destabilizes the bubbles when they come into contact with its water-repelling surface. This makes the boiling water retreat. ... The wooden spoon, being considerably cooler than 100°C, thus works to break the bubbles and make the foam retreat
