4% starch solution will decrease in volume.
This is because the less starch concentration, the more water molecules exists. Since 4% is less than 10%, so the 4% will contain more water. Water molecules tend to flow from a region of higher water potential to a region of lower water potential through the semi permeable membrane in osmosis. Therefore, since the 4% contains more water, the water there will flow away from the 4% and to the 10% one in order to reach equilibrium.
Answer:
a. 0.171M
b. 0.0938M
c. 0.284
d. 1.99atm
e. 1.88
Explanation:
Hello,
In this case, for the given reaction whose balance should be corrected as:
For which the law of mass action, in terms of the change due to stoichiometry and the reaction extent, turns out:
Thus, the initial concentration of hydrogen sulfide is:
Now, since the equilibrium amount of sulfur is given, the change due to equilibrium reaching is:
Therefore:
a. Equilibrium concentration of hydrogen:
b. Equilibrium concentration of hydrogen sulfide:
c.) Equilibrium constant, Kc:
d.) Partial pressure of sulfur gas:
e. Kc, for the reaction:
In that case, it equals the inverse halved initial reaction, whose modification is related as:
Best regards.
Answer:
0.3 J
Explanation:
The equation for heat capacity is Q = mcΔT where Q is the heat, m is the mass of the substance, c is the specific heat capacity of the substance and delta T is the change in temperature. Plugging those values into the equation, we have Q = (.500)(0.24)(27.5-25) = 0.3
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.
