The number of grams of copper reacted is 445 grams
<u><em>calculation</em></u>
2Cu +O₂ → 2CuO
from equation above the mole ratio of Cu:CUO is 2:2 =1:1, therefore the moles of Cu is also= 7.00 moles
mass=moles x molar mass
from periodic table the molar mass of Cu= 63.5 g/mol
mass= 7.00 moles x 63.5 g/mol =445 grams
Answer:
claim to be scientific, yet do not follow all the rules of science
Explanation:
Pseudoscience as the name implies "pseudo=false" means false science. It is a practice which poses itself as being scientific but does not conform to scientific principles or methods. In other words, they claim to be scientific but in the actual sense, they are not because they do not follow the rules guiding scientific knowledge.
Examples of pseudoscience as stated in the question are astrology, biorhythms. These ideas or studies are not subject to principles that qualifies them to be scientific.
Greetings!
I believe the answer is true.
While precipitation does require a lot of energy, evaporation takes longer, and requires more energy from heat, whereas precipitation doesn't really require any.
Hope this helps you!
