Thermal decomposition of rail car load of limestone to lime and carbon dioxide requires 7.92 x 106 kj of heat. convert this energy to calories. once you have the value, determine its log (base 10) and enter this in decimal format with three decimal places. do not include units.

Explanation:

As we know that one kilo joules is equal to gram calories

Given ,

Energy required by thermal decomposition of rail car load of limestone to lime and carbon dioxide is equal to

Kilo joules

This kilo joules of energy is converted into calories and is equal to

On taking the log of this value, we get -

log ()

Hence, the answer is

the way that the mass of carbon can be conserved through cellular respiration is through a process/law called the law of conservation of mass which even tho it undergoes a process, mass is not be destroyed or changed

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.
