Answer:
atmosphere
Explanation:
atmosphere is composed of all air particles surrounding the Earth
biosphere is composed of all living organisms on the Earth
hydrosphere is composed of all water particles in the Earth
I guess geosphere is all about rocks and soils
Answer:
m = 176.12 g
Explanation:
Let's write the reaction again:
Mg(s) + 2HCl(aq) --------> MgCl₂(aq) + H₂(g)
This reaction is a simple displacement reaction, in this case, the magnesium is displacing the atoms of hydrogens to form MgCl₂. 1 mole of Mg reacts with 2 moles of HCl. If the magnesium is the limiting reactant, we need to calculate the theorical yield of MgCl₂. The mole ratio between these two is 1:1 so, all we have to do is calculate the moles of magnesium and then the moles of MgCl₂:
moles Mg = 45 / 24.3 = 1.85 moles
As the mole ratio is 1:1 then:
moles Mg = moles MgCl₂ = 1.85 moles
Now, we calculate the mass using the molecular mass:
m = 1.85 * 95.2
<h2>
m MgCl₂ = 176.12 g</h2><h2>
This is the theorical yield</h2>
The answer is A.
215K is equivalent to -58.15 °C and temperature corresponds with the average kinetic energy.
So the 15°C has a higher energy level than 215K.

What's the question so I can help?
I will just edit my answer when you have asked your question and post it here.
Explanation:
Answer;
Mutation rate
-Mutation rate is not a difference between a population showing exponential growth and a population showing logistic growth.
Explanation;
-When the resources are unlimited, populations exhibit exponential growth, resulting in a J-shaped curve and when the resources are limited, populations exhibit logistic growth.
-The carrying capacity is the maximum population size of the species that the environment can sustain indefinitely, given the food, habitat, water, and other necessities available in the environment. It affects the size of population and thus has an effect on both exponential and logistic growth.
-Food limits and disease limits are also other factors that may determine the population size in a biological ecosystem.
