<span>∆T = i * Kf * m
Kf(cryoscopic constant of water) = -1.858°C·kg/mol
i = 1 (for glycerin)
m = molality of solute(glycerin) = nos of moles of glycerin / mass of solvent(water)[n/M]
n = 30.7g/92.09g = 0.33337moles
M is deduced from the density of water which is 1Kg/1000ml(1Kg/L)
M = 376ml * (1Kg/1000ml) = 0.376Kg
m is thus; 0.33337moles/0.376Kg = 0.8866mol/Kg
=> ∆T = 0.8866mol/Kg * 1 * -1.858°C·kg/mol
∆T = -1.647°C
~ -1.65°C.</span>
Answer:
The answer is A, a democracy.
Explanation:
A country must meet the requirements or rules to join the European Union. These rules are called the "Copenhagen Criteria" and outlines the requirements needed. They are defined as:
1) The country's institutions must preserve democratic governance and human rights,
2) Has a market economy that is fully functional, and
3) Intends to uphold the obligations of joining the European Union.
The rules set forth are named after the 1993 European Council meeting in Copenhagen, Denmark. Over the years, many European governing bodies have made adjustments to these rules, such as the European Parliament, the European Commission, and the European Court of Justice and Human Rights.
The answer is B. Russia's fertile soil is extremely depleted from constant use.
I believe it was the failure of pumps and levees, to keep the floods from happening.
Answer:
A.
Explanation:
Groundwater recharge or deep drainage or deep percolation is a hydrologic process, where water moves downward from surface water to groundwater. Recharge is the primary method through which water enters an aquifer.
