Why does permeable rock weather more quickly than less permeable rock

Chemistry

a permeable rock weathers chemically at a fast rate because as water seeps through the spaces in the rock, it removes dissolved material formed by weathering. why does chemical weathering occur more quickly in a hot climate.

Under what pressure will a scientist need to store 0.400 miles of gas if the container has a volume of 200.0 mL and the temperat
mihalych1998 [28]
Hello!

Ok so for this problem we use the ideal gas law of PV=nRT and I take it that the scientist needs to store 0.400 moles of gas and not miles.

So if we have
n=0.400mol
V=0.200L
T= 23degC= 273k+23c=296k
R=ideal gas constant= 0.0821 L*atm/mol*k

So now we rearrange equation for pressure(P)

P=nRT/V
P=((0.400mol)*(0.0821 L*atm/mol*k)*(296k))/(0.200L) = 48.6 atm of pressure

Hope this helps you understand the concept and how to solve yourself in the future!! Any questions, please feel free to ask!! Thank you kindly!!!

what is the molarity of a solution made by dissolving 18.5 grams of NaCL into enough water to reach 450.0ML​
ValentinkaMS [17]

Answer:

0.702M

Explanation:

Molarity of a solution, which refers to the molar concentration of that solution can be calculated thus;

Molarity = number of moles (n) ÷ volume (V)

Firstly, we convert 18.5 grams of NaCl to moles using the formula; mole = mass/molar mass

molar mass of NaCl = 23 + 35.5 = 58.5g/mol

mole = 18.5/58.5

mole = 0.32moles

Volume of water (V) = 450mL = 450/1000 = 0.450L

Molarity = n/V

Molarity = 0.32/0.450

Molarity = 0.702M
