Answer:
164atm
Explanation:
Given parameters:
Initial pressure = 150atm
Initial temperature = 27°C = 27 + 273 = 300K
New temperature = 55°C = 328K
Unknown:
New pressure = ?
Solution:
At constant volume, the pressure of a given gas varies directly with the absolute temperature.
Mathematically;
=
P and T are pressure and temperature values
1 and 2 are the initial and new states
Insert the parameters and solve;
=
300P₂ = 150 x 328
P₂ = 164atm
0.52kg = 520g
520g x 0.35 = 182g
182 x 6.022x10^23 = 1.096004E26
1.096004E26 / 107.8 = 1.0167012987E24 atoms
m(NaOH)=20 g
M(NaOH) = 23+16+1=40 g/mol
20 g*1 mol/40 g= 0.50 mol
0.05 mol NaOH
It was by far "warm and wet growing seasons" that was the most important factor in terms of the South's economic development. Cotton and tobacco were the biggest exports.
Explanation:
These crops created tons of cash, had massive markets round the world, however required a stable and enormous hands to grow and harvest them.The yank South is understood for its long, hot summers, and wealthy soils in stream valleys creating it a perfect location for growing cotton. the various southern seaports and riverside docks allowed shipping cotton to remote destinations. By 1860, Southern plantations equipped seventy fifth of the world's cotton, with shipments from Houston, city, Charleston, Mobile, Savannah, and some different ports. The unquenchable European demand for cotton was a results of the commercial Revolution that created the machinery and factories to method raw cotton into vesture that was higher and cheaper than hand-made product.
