The combustion of methane, CH4, releases 890.4 kJ/mol. That is, when one mole of methane is burned, 890.4 kJ are given off to the surroundings. This means that the products have 890.4 kJ less than the reactants.
Answer:
THE AMOUNT OF HEAT ABSORBED DURING THE REACTION IS 151.64 JOULES
Explanation:
Mass = 12.58 g
Specific heat of CaCO3 = 0.82 J/g K
Change in temperature = 38.3 C - 23.6 C = 14.7 C
How many joules of heat are absorbed?
Heat of a reaction is the amount of heat absorbed or evolved when a gram of a sample is raised by 1 C.
Heat = mass * specific heat * change in temperature
Heat = 12.58 * 0.82 * 14.7
Heat = 151.64 J
The amount of joules absorbed during this reaction is 151.64 J.
Answer:
If the choices were coal, petroleum, and natural gas, I would say that petroleum has the greatest impact on the CO₂ levels in the atmosphere. I chose petroleum because of transportation, such as cars, trucks, planes, and more.
Answer:
A beach forms when waves store sand and rock along the shoreline. A few sea shores are comprised of rocks and stones. After some time, they are moved around smooth by the waves.
Explanation:
A beach is a geologic arrangement that is situated along a huge waterway, including lakes, streams, and seas. Sea shores are described by the presence of small bits of natural silt. The dregs might be made out of sand, rock, shell, green growth, or stones. Normal sea shores may take a large number of years to advance, a cycle that is the consequence of continually moving water that disintegrates the land situated around its edge. Basically, rocks or coral reefs situated off the shore are worn out by moving waves. Moreover, streams and rainwaters may dissolve rocks found further inland. These dregs are stored along the coastline, framing a sea shore.
