Answer:
Most erosion is performed by liquid water, wind, or ice (usually in the form of a glacier). If the wind is dusty, or water or glacial ice is muddy, erosion is taking place. The brown color indicates that bits of rock and soil are suspended in the fluid (air or water) and being transported from one place to another. This transported material is called sediment.

Answer:
Explanation:
Ok, so I suppose you meant NaCl. But ok:
So we have the formula moles = grams/MM, where MM is molar mass. The molar mass of NaCl is 58.44 g/mol. That means that 55/58.44 is the number of moles which appears to be 0.94 moles.
Answer:
a) Mass of solid W crystallized out 0°C is 141.564 g
b) 91.92% is the percent recovery.
Explanation:
The solubility of solid W in water at 100°C = 21.3 g/100 mL
Volume of water at 100C required to dissolve 154.0 g of W: x


723.0 mL of water will dissolve 154.0 grams of solid W.
The solubility of solid W in water at 0°C = 1.72 g/100 mL
Mass of W soluble in 723.00 mL of water at 0°C = m


a) Mass of solid W crystallized out 0°C : 154.0 g- 12.436 g=141.564 g
b) Percent recovery of solid at 0°C:

91.92% is the percent recovery.
It is Iron 2 (Fe2) and Oxygen 3 (O3). Hope this helps!
