Answer:
0.2g
Explanation:
mass=mole/molar mass
molar mass of oxygen is 32
6.06/32=0.19 or 0.2 units=grams
Answer:
1. a simulation 2. saurology
Explanation:
2. D) A solution that has more solute in it than it can hold is called a supersaturated solution. An easy way to know this is because super means that there is more.
3. I'm not sure about this one, but all I can tell you is that the gram formula mass of H2SO4 is 98 grams.
4. D) C2H6SO is the empirical formula. We know this because all of the subscripts are simplified as much as possible. You might try to simplify the C2 and H6 but take note that the S and O have no subscripts, so elements cannot be simplified anymore.
5. D) ethanoic acid (C2H4O2) has the same empirical formula as glucose. The empirical formula of glucose is CH2O. This is because the subscripts of 6/12/6 have a common factor of 6, so we divide them all by 6 to get subscripts of 1/2/1. Ethanoic acid has subscripts of 2/4/2. They have a common factor of 2, so when we divide them by 2, they will become 1/2/1.
The two ways that climate change can degrade soil are due to carbon dioxide content in soil and its effect on the ecosystem.
Explanation:
When the concentration of carbon dioxide in the atmosphere increases the organisms such as microbes in the soil break down the organic matter and causes even more increase in the carbon dioxide content. This leads to the release of greenhouse gases which further releases a large amount of methane which is harmful.
Secondly, there should always be a balance between the soil and the climate otherwise it would affect the natural and semi-natural ecosystems. When there are changes in the distribution of water to the plants it affects the hydro-logical cycle. Thus, climate change will naturally lead to changes in the functions of soil and degradation occurs.
