Answer:
Wind: Inconsistent power supply is one of the biggest drawbacks of utilizing wind turbines to generate electricity.
Solar: The main disadvantage of solar energy is cost, particularly in the start-up phase.
Explanation:
The signs of ΔS° and ΔH° will be negative.
A combustion reaction is a reaction in which a substance reacts with oxygen gas, releasing energy in the form of light and heat.
Combustion reactions must involve O2 as one reactant.
Consider the combustion of butane gas:
C₄H₁₀(g ) + 13/2O₂(g) → 4CO₂(g) + 5H₂O(g)
4 + 13/2 4 + 5
10.5 mol -------------> 9 mol
As the number of moles decreases entropy will decrease
so ΔS° = negative
since this example for combustion reaction heat is released (exothermic)
so ΔH° = negative.

Answer:
Electrons on the outermost shell of an atom. They are responsible for the chemical properties of an atom.
Answer:
heres the answer: Daily changes in the weather are due to winds and storms. Seasonal changes are due to the Earth revolving around the sun, differences in temperature create a restless movement of air and water in great swirling currents to distribute heat energy from the Sun across the planet.
