<span>The three main types of erosion caused by glaciers are plucking, abrasion, and freeze thawing. Plucking forces rocks off of the back wall when glacier water melts and re-freezes around cracked and broken rocks. Abrasion occurs when rocks frozen to the base of the glacier scrape the bed rock. Freeze thawing occurs when melted water gets into the bed rock. An outwash plain is an area formed by sediments at the terminus of a glacier. Outwash plains may contain suficial braided stream complexes, and kettle lakes. The outwash plains originate from melting ice deposits.</span>

A sample of air was collected on a day when the total atmosphere pressure was
zhuklara [117]

Answer:

1. The gas law used: Dalton's law of partial pressure.

2. Pressure of nitrogen = 331 mmHg

Explanation:

From the question given above, the following data were obtained:

Total pressure (Pₜ) = 592 mmHg

Pressure of Oxygen (Pₒ) = 261 mmHg

Pressure of nitrogen (Pₙ) =?

The pressure of nitrogen in the sample can be obtained by using the Dalton's law of partial pressure. This is illustrated below:

Pₜ = Pₒ + Pₙ

592 = 261 + Pₙ

Collect like terms

592 – 261 = Pₙ

331 = Pₙ

Pₙ = 331 mmHg

Therefore, the pressure of nitrogen in the sample is 331 mmHg

If i add 25 mL of water to 125 mL of a 0.15 M NaOH solution, what will the molarity of the diluted solution be ?
marshall27 [118]
1000 mL=1L

25 mL = 0.025 L
125 mL = 0.125 L

M1V1=M2V2
0.15(0.125) = M2(0.025)
0.01875 = M2(0.025)
0.75 = M2

0.75 M

Compare and contrast melting and sublimation. Can all materials sublime?
kupik [55]

Answer:

Sublimation describes a solid turning directly into a gas. Melting occurs when a solid turns into a liquid. Water can, under the right circumstances, sublimate, though it usually melts at temperatures above 0 degrees Celsius or 32 degrees Fahrenheit.

Explanation: Carbon dioxide (CO2), however, is very different. The conditions that determine whether CO2 melts or sublimates are both temperature and atmospheric pressure.
