Answer:
C
Explanation:
trees (as well as other plants) produce carbon dioxide. deforestation is the removal of trees. this will not cause an increase in any pollutants such as ozone. ozone is made from VOCs and other harmful pollutants, and not caused by trees. tearing down trees will also not create more soil. So the answer has to be C
Answer:
2.8248 g
Explanation:
First, consider the balanced chemical equation:
Then we calculate the number of moles in 4.11 g of citric acid:
n(citric acid)=
According to the balanced reaction, one mole of citric acid produces 3 moles of carbon dioxide. That's 3 times the number f moles of citric acid. So we will do the same with the available number of moles of citric acid.
so n(carbon dioxide) = 0.0214 mol*3=0.0642 mol
mass(carbon dioxide)= mass*molar mass=0.0642 mol* 44g/mol
= 2.8248 g
This plateau is where a phase change occurs. Likely, this cooling curve observes the changing of a liquid into a solid (so that the temperature is quantifiable). As something cools, it’s losing energy to the surroundings; when a phase change occurs, like liquid to solid, energy isn’t lost directly from the atom, but instead the energy maintained by free motion of the atom is used. This lack of motion reduces it into a lattice (all while maintaining a constant internal energy), finalizing the phase change, after which energy is lost directly from the atom again.
Because the molecular solutions have low melting and boiling points, and do not conduct electricity.
Which curve or point of a phase diagram would indicate the melting point at various temperatures and pressures?
fusion curve
