Explanation:
Human activities commonly affect the distribution, quantity, and chemical quality of water resources. The range in human activities that affect the interaction of ground water and surfa.ce water
The effects of human activity on groundwater and surface water in a watershe, Watersheds directly affect water quality, whether it's for drinking or recreation. For example, algae blooms from fertilizer runoff draining into water harm watershed health, as do mercury and lead seeping into the water supply due to pollution. ... The polluted water supply that results can become harmful to humans.
a result, most water becomes polluted by human activities. These include: throwing sewage and industrial waste into rivers and oceans, using harmful fertilizers, and even littering. All of these human activities affect our water sources. ... Water pollution affects the plants, animals, and soil around the river.
Answer : The enthalpy change of dissolution of is -54.0 kJ/mole
Explanation :
where,
q = heat released by the solution
c = specific heat of water =
m = mass of solution = mass of water + mass of = 102.00 + 1.69 = 103.69 g
= change in temperature =
Now put all the given values in the above formula, we get:
Now we have to calculate the enthalpy change of dissolution of
where,
= enthalpy change of dissolution = ?
q = heat released = 0.659 kJ
m = mass of = 1.69 g
Molar mass of = 138.55 g/mol
Therefore, the enthalpy change of dissolution of is -54.0 kJ/mole
Answer:
really hyped up and excited
S + 2HNO3---> H2SO4 + 2NO
Answer:
Explanation:
molar volume=moles*given volume
for molar concentration we use two formulas molarity and molality
molarity=no of moles/volume
molality=no of moles/kilogram
