All tropical cyclones can produce widespread torrential rains, which cause massive flooding and trigger landslides and debris flows.
Answer:
A. Heat the solution
Explanation:
To make a supersaturated solution, make a saturated solution of sugar by adding 360 grams of sugar to 100 mL of water at 80 degrees Celsius. When the water cools back down to 25 degrees, that 360 grams of sugar will still be dissolved even though the water should only dissolve 210 grams of sugar.
Answer:
Benzaldehyde is less electrophilic than acetaldehyde
Explanation:
Electrophilicity of carbonyl carbon depends on it's positive charge density.
In benzaldehyde, phenyl group can act as an electron donating group towards carbonyl group due to it's electron donating resonating effect.
In acetaldehyde, methyl group can act as an electron donating group towards carbonyl group due to it's electron donating inductive effect.
We know that resonating effect are more stronger than inductive effect.
Henece, it is expected that positive charge density on carbonyl carbon is much lower in benzaldehyde than acetaldehyde.
So, benzaldehyde is less electrophilic than acetaldehyde.
Resonating effect of phenyl group has been shown below.
Answer:
D. mass has a greater effect than height on gravitational potential energy
Explanation:
The higher up an object is the greater its gravitational potential energy. The larger the distance something falls through the greater the amount of gravitational potential energy the object loses as it falls. ... This is because a tree has more mass, so it needs to be given more gravitational potential energy to reach the same height.More massive objects have greater gravitational potential energy.
D) 60°C
Explanation:
The molecules of Nitrogen gas will have the highest average kinetic energy when their temperature is the highest.
According the kinetic molecular theory, the temperature of gases is directly proportional to their average kinetic energy.
The higher the temperature, the more kinetic energy they possess.
To find out the highest temperature from the given options, we need to solve and express all the given options in a single unit of temperature.
K = 273 + °C
Let us convert all to Kelvin;
-40°C;
K = 273 + (-40) = 233K
60°C;
K = 273 + 60 = 333K
We can see that 60°C has the highest temperature in kelvin and this will furnish the gas with the greatest average kinetic energy.
