Answer:
THE PRESSURE EXERTED BY THE GAS IS THEREFORE 2.88 atm.
Explanation:
Boyle's law states that at constant temperature, the volume of a given mass of gas is inversely proportional to the pressure of the gas.
Mathematically, P1 V1 = P2 V2
Write out the values of the variables given:
P1 = 2.4 atm
V1 = 1.8 L
V2 = 1.5 L
P2 = unknown
Re-arranging the variables by making P2 the subject of the equation, we have:
P2 = P1 V1 / V2
P2 = 2.4 * 1.8 / 1.5
P2 = 2.9=88 atm
Hence, the pressure exerted by the gas is therefore 2.88 atm
The general process for coal mining and refining is option C.
Coal mining is carried out by two main processes based on the depth, quality, thickness, and structure of coal seam. Based on the depth, coal seam of less than 180ft to the surface is surface mined while coal seems between 180ft.-300ft. are deep mined. The coal mined is transported to a nearby processing plant using a conveyor, train, ship, etc. where it is washed to remove other component like dirt, sulphur, rocks, etc. and afterwards dried.
Answer:
The heat could put stress on the metabolism, which could lead to dehydration. Energy drinks are designed to be stimulants and can give people a little edge when playing sports. They can also be dangerous because stimulants can increase body temperature and pose a hypothermia threat. But if you leav it in the stove then it the liquid would eventually evaporate and the sugar would be left. But, that also would leave the rest of the sugar which would look like tar or slime.
As per the problem 2 moles of propane are produced when 7 moles of carbon are supplied
so if we supply 1 mole of carbon the moles of propane obtained = 2 /7
if we supply 1.4 moles of carbon the moles of propane obtained = 2 X 1.4 /7 = 0.4 moles of propane
Hence answer is propane we can produce using this reaction = 0.4 moles from 1.4 moles of carbon
