Explanation:
Structureless rocks like granite and other intrusive rocks tend to weather into characteristic rounded shapes through this process
Explanation:
Algae is a group of a photosynthetic eukaryotic organisms that plays a very important role on the ecosystem. It forms the lower base of the food chain and supports all the life forms of the ecosystem. It takes up water and carbon dioxide from the atmosphere to prepare food during the process of photosynthesis and maintains a balance in the ecosystem.
In the context, if the algae disappears, the fish might die as the small fishes feeds on this algae. This is a concern as the algae is main component of food source and forms the base of the food chain. If there will be no algae there will be no life form on earth, as all species depend on each other to survive.
In order to prevent this from occurring, we must protect our algae. We must plant more trees, keep our water bodies healthy, we should not litter our ponds and lakes. We should also help these algae to grow and survive so that other life forms can feed them and thus maintain the ecosystem.
767.448 Joules of heat is required.
You use the equation Q=MCdeltaT
Make sure you convery celsius to Kelvin
Specific heat of water is 4.18
So it will be Q=2.55(4.18)(72)
Q=767.448
The equation CH4 + O2 ? CO2 + H2O is not balanced because there are four hydrogen atoms in the reactant side of the equation and only two on the product side. for balancing this equation we add 2 withO2 in reactants and add 2 with H2O in products.
22.4L.
This is because the standard conversion factor for Liters is 22.4 and in the question it explicitly states liters of CO2.
Therefore, in order to convert Liters of CO2 to Moles of CO2, you'd need to use the conversion factor of 22.4.
Hope this helps!
