Hello :)

I just took the quiz, so let me give you a step-by-step explanation of how I solved the problem. Disregard the 25 degrees, it is not needed to find the answer

pH + pOH = 14

4.48 (4.48 is the given pH in problem) + pOH = 14

4.48-4.48 + pOH = 14-4.48 (subtract 4.48 from 14)

pOH = 9.52 (letter c)

Hope this helped :)

What mass of natural gas (CH4) must you burn to emit 264 kJ of heat?
mariarad [96]
The heat released by cpmolete the combustion of organic products with oxygen is called heat of combustion.

Here 1 mol of CH4 realesed 802.3 KJ

To emit 264 kJ you multiply you need (1 mol of CH4/802.3 kJ)* 264 kJ = 0.329 mol of CH4

The molar mass, MM, of CH4 is 12 g/mol + 4*1g/mol = 16 g/mol

The to obtain the mass multiply the number of moles times the molar mass:

mass = n * MM = 0.329mol * 16g/mol = 5.26 grams

Answer: 5.26 grams

Wind transports large rocks by _____.
julsineya [31]
Wind transports large rocks by rock erosion. Erosion should be distinguished from weathering. Erosion is the movement of rocks from one place to other location due to external factors like wind, water or gravity. Weathering, on the other hand, is the breaking of rock into smaller pieces by processes.
