Funding to prevent deforestation should only be directed at tropical rainforests.
a_sh-v [17]

The correct answer is - False.

The funding for the preservation of the forests should be equally distributed for all the forests on the planet. The tropical rain forests are the thickest, the ones that have the largest biodiversity, and they are the ones that produce the highest levels of oxygen, but that doesn't mean that they are the only ones that need protection. The largest forests in the world are actually not the tropical rain forests, but instead it is the taiga, stretching from Scandinavia, throughout all the length of Russia, and throughout all the length of Canada. The mid latitudes are covered with deciduous forests, and they play a crucial role in this parts of the world, both in cleaning the air, providing oxygen, as well as supporting the ecosystems.

A solution is prepared by mixing 525 mL of ethanol with 597 mL of water. The molarity of ethanol in the resulting solution is 8.
Alenkinab [10]

Answer:

\Delta V = 234.736\,mL

Explanation:

The quantity of moles of ethanol in the solution is:

n_{C_{2}H_{5}OH} = \left(\frac{597\,mL}{1000\,mL} \right)\cdot \left(8.35\,\frac{mol}{L} \right)

n_{C_{2}H_{5}OH} = 4.985\,mol

The mass and volume of ethanol in the solution are, respectively:

m_{C_{2}H_{5}OH} = (4.985\,mol)\cdot \left(46.07\,\frac{g}{mol} \right)

m_{C_{2}H_{5}OH} = 229.658\,g

V_{C_{2}H_{5}OH} = \frac{229.658\,g}{0.7893\,\frac{g}{mL} }

V_{C_{2}H_{5}OH} = 290.964\,mL

The difference between the total volume of water and ethanol mixed to prepare the solution and the actual volume of solution is:

\Delta V = (525\,mL+597\,mL) - (597\,mL + 290.964\,mL)

\Delta V = 234.736\,mL

Vein deposits are usually produced by _____. weathering density sorting hydrothermal solutions cementation
mart [117]

Answer:

Hydrothermal solutions

Explanation:

Vein deposits which cuts through rock layers are usually products of hydrothermal solutions.

Veins are rich ore deposits in which superheated water rich in dissolved minerals penetrated through a rock body and the minerals becomes precipitated and deposited in the process. Most veins have small width and a great length. Some occurs as veinlets depending on the nature of the weaknesses they trace out in a rock body.

Veins contains minerals such as gold, copper ore, rare earth metals. Most hydrothermal solutions contains minerals that are not compatible with the melt as rocks crystallize. They preferred to be carried with super heated water which deposits them seperately.
