How is cellular rep presentation the reverse of photosynthesis

1 answer:

7 0

Cellular respiration is the reverse of photosynthesis because it is glucose + oxygen yield carbon dioxide water and ATP while photosynthesis is carbon + water yields oxygen and glucose. Cellular respiration is the way cells gain energy from the sun. Photosynthesis is the plants way of producing energy and these processes are basically the reverse of the other .

Which would exert more pressure on the floor, a 100kg man wearing snow shoes or a 60kg woman wearing high heels? PLEASE EXPLAIN

iris [78.8K]

Pressure can be defined as the force acting on a perpendicular surface per unit area.

Force exerted by a man of mass 100 kg wearing snow shoes = m.a

Where m = mass of the man = 100 kg

a = acceleration due to gravity= 9.8 $m/s^{2}$

Force exerted by the man of mass 100 kg = $100 kg(9.8 m/s^{2}) = 980 N$

Force exerted by woman of mass 60 kg = $60 kg(9.8 m/s^{2}) = 588 N$

Force exerted by 100 kg man is greater than that exerted as 60 kg woman. The area on which this force is acting determines the pressure. Pressure is inversely proportional to the area on which the force acts. Therefore, the pressure exerted by 100 kg man wearing snow shoes is less than the pressure exerted by a 60 kg woman woman wearing high heels as the force acts over a larger area when the man wears snow shoes when compared to the force exerted over a smaller area in case of the woman wearing high heels.

1. big bang-the most accepted theory on the origin of the universe 
2. steady state-all is the same and will always stay the same 
3. oscillating universe-agrees with the big bang theory, but insists the universe expanded much quicker

What volume of CH4(g), measured at 25oC and 745 Torr, must be burned in excess oxygen to release 1.00 x 106 kJ of heat to the su

anastassius [24]

Answer:

$V=27992L=28.00m^3$

Explanation:

Hello,

In this case, the combustion of methane is shown below:

$CH_4+2O_2\rightarrow CO_2+2H_2O$

And has a heat of combustion of −890.8 kJ/mol, for which the burnt moles are:

$n_{CH_4}=\frac{-1.00x10^6kJ}{-890.8kJ/mol}= 1122.6molCH_4$

Whereas is consider the total released heat to the surroundings (negative as it is exiting heat) and the aforementioned heat of combustion. Then, by using the ideal gas equation, we are able to compute the volume at 25 °C (298K) and 745 torr (0.98 atm) that must be measured:

$PV=nRT\\\\V=\frac{nRT}{P}=\frac{1122.6mol*0.082\frac{atm*L}{mol*K}*298K}{0.98atm}\\\\V=27992L=28.00m^3$

Best regards.
