The environment affects natural selection. Speices need to adapt to changes in environmnet. The weaker organisms which fail to adapt to environment perish while the stronger ones who adapt to the environment survive. This is how environment affects natural selection.
Volume in liters:
870 mL / 1000 => 0.87 L
Moles ( CO₂) = molarity x volume
Moles (CO₂) = 0.75 x 0.87
= 0.6525 moles of CO₂
hope this helps!
<em>Answer:</em>
<em>Chemical equations must be balanced to satisfy the law of conservation of matter, that states that matter cannot be produced or destroyed in a closed system. The law of conservation of mass governs the balancing of a chemical equation.</em>
Explanation:
Answer:
ΔS = 16.569 J/K
Explanation:
In this case, we need to use the correct expression to solve this. In thermodynamics, the expression to use that puts a relation between heat, temperature and entropy is the following:
ΔS = Q/T
To determine the entropy change of the universe, we need to sum the entropy change of Earth and the entropy of the sun.
As the sun is transfering radiation to Earth, the sun is losing energy, therefore, heat is negative, while Earth receives the heat, so it's positive. Calculating the entropy for the sun and Earth:
ΔSs = -Q/Ts
ΔSe = Q/Te
ΔSu = ΔSe + ΔSs
Let's calculate both entropies by separate:
ΔSe = 5x10^3 / 285 = 17.54 J/K
ΔSs = -5x10^3 / 5,150 = -0.971 J/K
Therefore, the entropy of universe:
ΔSu = 17.54 - 0.971
ΔSu = 16.569 J/K
