RMM of CaH2=20+(1x2)=22
Number of moles or formula units
=mass/RMM
=8.294/22
=0.377
Answer:
Explanation:
Carbon sink is basically anything that absorbs carbon from the atmosphere. Particularly, the soil, trees, plants and the ocean absorb the most carbon, which helps with greenhouse emission.
<span>Answer:
Moles Ca(NO3)2 = 100 x 0.250 / 1000 = 0.025
Ca(NO3)2 >> Ca2+ + 2NO3-
Moles NO3- = 2 x 0.025 = 0.05
Moles HNO3 = 400 x 0.100 / 1000 = 0.04
Total moles = 0.05 + 0.04 = 0.09
Total volume = 500 ml = 0.500 L
M = 0.09 / 0.500 = 0.18</span>
Answer:
true because of the elements
combustion is when you burn something in presence e of oxygen and the products will be mainly the CO2 and H2O
