Answer:
B
as the flows along the outside edge of a curve it removes rock and soil from the river bank
Answer: 0.050M urea, 0.10M glucose, 0.2M sucrose, pure water
Explanation:
Vapor pressure refers to the ease with which a liquid substance is transformed into vapour. High vapour density implies that the liquid is easily transformed into gas. Pure water is expected to have the lowest vapour density since it is held by strong intermolecular forces in the liquid state. Urea is an organic liquid held by weak Van der Waals forces hence its extremely high vapor pressure.
Cause the heavier object makes you use a lot of force and the smaller object make you use less Force if that makes sense haha

Answer:
There correct answer is option 1 (-50100 J)
Explanation:
Step 1: Data given
Mass of water = 150.0 grams
ΔHfus = 334 J/g
Temperature = 0°C
ΔHfus = the amount of energy needed to change phase of 1 mol water to ice
Step 2: Calculate the amount of heat required
Q = m*ΔHfus
⇒Q = the amount of heat reuired = TO BE DETERMINED
⇒m =the mass of water = 150.0 grams
⇒ΔHfus = 334 J/g
Q = 150.0 grams * 334 J/g
Q = 50100 J of heat required
Step 3: Calculate heat released
Qrequired = -Q released
Qreleased = -50100 J
There correct answer is option 1 (-50100 J)
