D.
Since she's not driving her car, there is no carbon emissions emitting from her car. Thus, there will be less carbon dioxide in the atmosphere in comparison if she were to drive her car. Good luck!
A con that is that eventually all of the forest will be destroyed.
Explanation:
The clearcutting method is a method that is often used around the world, so it is no wonder that this happens in Oregon as well. While the clearcutting manages to supply the market and even create surplus with timber and later its products, it also has several negatives about it. One major con about the clearcutting is that eventually all of the forest will be destroyed.
Because this method is based on mass cutting down of wood and not using any sustainable means, such as planting saplings on the places that were cut and cleared, it has terrible effects on the long run. Bit by bit, the forest will be cut in total, and because it was not renewed in meantime, the only thing that will be left behind will be barren and heavily eroded land.
This will cause big problem for the timber industry as they will have nothing to work with. The prices of the timber products will skyrocket because of this. The ecosystem will be totally destroyed. The land won't be used for agriculture because the soil is of poor quality and because of high rates of erosion.
If ΔG is negative, the reaction is always spontaneous.
If ΔG is positive, the reaction is non-spontaneous and will require a sustained input of energy for it occur.
If ΔG is zero, the reaction is at equilibrium and no work can be done.
Answer:
D. A positive charge, because of a covalent bond with oxygen
Explanation:
A water molecule contain both hydrogen and oxygen atom. Water is a polar molecule because it has positive electric charge in one of it's poles and negative charge on the other. The hydrogen is positively charged and the oxygen is negatively charged which are bonded by covalent bond. Hydrogen is positively charged because it cannot attract electrons strongly like oxygen which is positively charged. There is unequal sharing of electrons in water molecules and this is why oxygen is slightly negative and hydrogen is slightly positive.
