Is mercury a poison for humans? + Example - Socratic
The mercury caused the hatters to become insane over time. Mercury poisoning may happen through bioaccumulation along food chain, as recognised in a community living near Japan's Minamata Bay. The disease was first reported as an unknown epidemic in 1956, but mercury as the causative agent was identified only in 1959.

Question #4793b - Socratic
Yes In addition to Lucio's explanation, gravitational potential energy depends on height. When you hear "potential energy" there is energy that is stored that can be released. For the case of any mass elevated by h (height above ground), it has the potential to fall down. The greater h, the greater amount it could fall and thus greater gravitational potential energy. For problems that ...

Maximum altitude ~~2.8m Ignoring air resistance, other sources of friction, etc., this problem can be solved with energy conservation: E_(mech)=K+U Where K is kinetic energy and U is potential energy. Thus, when energy is conserved in a system it should follow that E_i=E_f =>K_i+U_i=K_f+U_f From this relationship we can see that if potential energy, for example, were to decrease, kinetic ...

How does the kinetic theory of matter define heat? - Socratic
Kinetic theory of matter advocates atomism. We have a large number of identical (in some cases non identical as well) gas molecules moving with superb speed in all sorts of directions. All the thermal energy is associated with these molecules/atoms in their ever existing motion. Heat can be interpreted as the energy transfered between to systems without mechanical means! Let me explain below ...

A pyramid has a parallelogram shaped base and a peak directly above its center. Its base's sides have lengths of #7 # and #8 # and the pyramid's height is #5 #. If one of the base's corners has an angle of #pi/4#, what is the pyramid's surface area?

How does energy evolve in the INCOMPLETE combustion of benzene...?
You might have to qualify your question here. I can easily write a stoichiometric equation for the incomplete combustion of benzene: C_6H_6(l) + 6O_2(g) rarr 4CO_2(g) +CO(g)+C(s) +3H_2O(l) Is this balanced? Don't trust my arithmetic. Of course, I don't know that this precise stoichiometry will occur, but given thermodynamic parameters (which you have ommitted!), we could work out the enthalpy ...

What can cause electromagnetic energy to degrade as it ... - Socratic
Distance from origin. Electromagnetic radiation follows the Inverse Square law wherein it's intensity is inversely proportional to the square of the distance from the origin. (proportional to 1/r^2). This causes attenuation of the energy that you describe.

Question #62177 - Socratic
The cell use glucose for it's fuel in a process called "Cellular respiration" In the Cellular respiration, the cell breakdown glucose in the presence of oxygen and transforms it to smaller parts called "ATP" which is a type of energy that the cell can use any time without wasting. Besides, ATP(also known as energy currency is the power molecule used by all cells of an organism in order to keep ...

Question #04ff1 - Socratic
The change in free energy will be equal to "+173 kJ". Start with the balanced chemical equation for your reaction N_(2(g)) + O_(2(g)) -> color(red)(2)NO_((g)) Notice that the reaction produces color(red)(2) moles of nitric oxide; the standard enthlapy of formation is always given for the formation of 1 mole of a substance from its elements in their most stable form. This means that the ...

Question #6033f - Socratic
100g ⋅ 333.55 J 1g = 33,355 J This is the case because the enthalpy of fusion of water, ΔH fus, which tells you the energy needed to convert 1 g of ice at 0∘C to liquid water at 0∘C, is equal to 333.55 J g−1. This tells you that in order to convert 1 g of ice at 0∘C to liquid awter at 0∘C, you need to provide 333.55 J of heat.
