The three concerns that the residents of this area might be:
1) <span>The cost of not moving forward is extremely high, so they opposed the plan, as they think it would affect US economy
2) </span><span>Nuclear waste disposal capability is an environmental imperative, so their environment would be polluted by very radioactive materials.
3) </span>Demand for new nuclear plants also demands disposal capability which supports national security but again, their site will be no longer for them. But unfortunately, <span>Extensive studies consistently show Yucca Mountain to be a sound site for nuclear waste disposal so the plan can't be abolished.
Hope this helps!</span>
Answer:
Explanation:
mass of the solution m = 1.6 + 75 = 76.6 g
fall in temperature = 25 - 23.34 = 1.66°C
heat absorbed = mass x specific heat x fall in temperature
= 76.6 x 1.66 x 4.18
= 531.5 J .
= .5315 kJ .
mol weight of ammonium nitrate = 80 g
heat absorbed by 1.6 g = .5315 kJ
heat absorbed by 80 g or one mole = 26.575 kJ
enthalpy change ΔH = +26.575 kJ
b )
enthalpy of hydration = 2630 kJ / mol
lattice energy = enthalpy of hydration + enthalpy change
= 2630 + 26.575
= 2656.575 kJ .
Explanation:
The given data is:
The mass% of a solution is 7.
Mass of solution =450g
The mass of salt required can be calculated as shown below:
Substitute the given values in this formula to get the mass of solute that is salt:
Mass of salt =31.5g
Mass of solvent that is water = 450g-31.5g=418.5g
Explanation:
<h3>Here, mass = 5kg </h3><h3> acceleration = 10m/s^2</h3>
<h3>according to the question ;</h3><h3>F = m×a ( from 2nd law of motion)</h3><h3>F = 5kg × 10m/s^2</h3><h3>F = 50kgm/s^2 or NEWTON </h3>
<h3>SO THE FORCE NEEDED IS 50 NEWTON</h3>
