The question ask to predict the effect where as coal can be used to generate hydrogen gas by this endothermic reason and the best answer among your choices based on the element you give is letter C. raising the temperature of the reaction mixture. I hope my answer is correct
Impulse is the product of a force and the time during which that force acts on a body.
Explanation:
Number of moles(n)=Number of atoms(N)/Avogadro's constant.
Avogadro's constant=6.02×10²³
so we have
n=9.05×10²³/6.02×10²³
n=1.0503moles.
n=mass/molar mass
1.0503=mass/28
mass=1.0503×28
mass=29.4084g

Explanation:
Answer:
Is removed from the atmosphere by photosynthesis.
Explanation:
The carbon dioxide (CO2) is presented in the atmosphere and its cycle began with it's incoming by respiration, combustion of fuels and decomposition. The autotrophs, which realize photosynthesis, use CO2 as fuel to produce their food with Sun rays.
The CO2 comprises about 0.3% of the atmospheric gases, and in the past few years, its input is being higher than its removal of the atmosphere, which is aggravating the greenhouse effect. Besides, the atmosphere of Venus has higher levels of CO2.
