What is the boiling point of a 2.86 m solution of ammonium nitrate NH4NO3 Assume that the solvent is water which has a Kb of 0.51ºC m and a boiling point of 100.0ºC?
To find the boiling point elevation of the solution, you can use the formula: ΔTb = i * Kb * m, where i is the van't Hoff factor, Kb is the ebullioscopic constant, and m is the molality of the solution. Plug in the values given and solve for ΔTb. Then, add this value to the boiling point of the solvent (100.0°C) to find the boiling point of the solution.
What is a factor in the U.S. need to find alternative energy sources?
One factor is the desire to reduce dependence on fossil fuels, which have negative environmental impacts. Another factor is the need to address climate change by transitioning to cleaner and more sustainable energy sources. Additionally, increasing energy security and diversifying the energy mix are important considerations for the U.S.
What factor most influences the amount of solar enegry an area on earth receives?
The latitude of the area is the most influential factor in determining the amount of solar energy it receives. Areas closer to the equator receive more direct sunlight and therefore more solar energy compared to areas further from the equator. Other factors such as season, time of day, and cloud cover can also impact the amount of solar energy received.
What factor most influences the amount of solar energy absorbed at the earths surface?
The angle of incidence of the sun's rays is the factor that most influences the amount of solar energy absorbed at the Earth's surface. A higher angle means the rays have to pass through more atmosphere, reducing the intensity of the sunlight absorbed. Additionally, factors like cloud cover and air pollution can also impact the amount of solar energy reaching the surface.
How reliable is geothermal energy?
Geothermal energy is considered a reliable source of renewable energy because it provides continuous power 24/7, unlike solar or wind energy which are intermittent. Geothermal power plants have high uptime and can operate at a consistent capacity factor, making it a dependable energy source. However, its availability is limited to areas with accessible geothermal reservoirs.
Why is ammonium nitrate a good fertiliser?
nitrogen is often (though not always) the limiting factor in plant growth, and since both the ammonium (NH3) and the nitrate (NO3) both contain nitrogen (N) and plants can absorb both these molecules, it can inhance plant growth.
What factor would result in sugar dissolving in water faster?

How do you calculate nitrate content from nitrogen?
To calculate nitrate content from nitrogen, you use the formula: Nitrate (NO3-) = Nitrogen (N) x 4.43. This conversion factor accounts for the molecular weight of nitrate (62 g/mol) compared to nitrogen (14 g/mol).
What are the rates that effect the rate of dissolving?
The polarity of solute and solvent, the concentration, the temperature.
Is Q factor ratio of energy stored to energy dissipated?
yes ,Q factor is ratio of energy stored to energy dissipated
Vant's hoff factor of ca NO3 2?
Oh, dude, Vant Hoff factor is basically the number of particles a compound breaks into in a solution. So, for Ca(NO3)2, it's like, "Ca" is calcium, and "NO3" is nitrate, right? So, it's gonna break into three particles - one calcium ion and two nitrate ions. So, the Vant Hoff factor for Ca(NO3)2 is 3. Easy peasy, lemon squeezy!
What will happened to the ke if its velocity is reduced by 12 times?
Kinetic energy is proportional to the square of the speed. If you reduce the speed by a factor of 12, the kinetic energy will reduce by a factor of 12 x 12 = 144.Kinetic energy is proportional to the square of the speed. If you reduce the speed by a factor of 12, the kinetic energy will reduce by a factor of 12 x 12 = 144.Kinetic energy is proportional to the square of the speed. If you reduce the speed by a factor of 12, the kinetic energy will reduce by a factor of 12 x 12 = 144.Kinetic energy is proportional to the square of the speed. If you reduce the speed by a factor of 12, the kinetic energy will reduce by a factor of 12 x 12 = 144.
What is a exponential factor?
The exponential factor gives the proportion of collisions with kinetic energy greater than the activation energy
The amplitude of oscillation of a pendulum decays by a factor of 27.0 in 110 s By what factor has its energy decayed in that time?
27^2 = 729 is a factor of energy decayed. (time takes NO role in this case)
What is Q factor of a coil?
The Q factor of a coil, sometimes called the unloaded Q factor, is the ratio of the energy stored in the coil to the energy dissipated in the resistance of the wire.
What is quality factor of damped oscillation?
The quality factor (Q factor) of a damped oscillation is a measure of how "good" or efficient the oscillation is in terms of energy loss. It represents the ratio of the energy stored in the oscillator to the energy dissipated per cycle. A higher Q factor indicates lower energy loss and a more efficient oscillation.
Increasing the temperature of a blackbody by a factor of 3 will increase its energy by a factor of?
