The grams are in 0.0150 moles of caffeine C8H10N4O2
mass = moles of C8H10N4O2 x molar mass of C8H10N4O2
= 194g/mol x 0.0150mol = 2.91 grams
there is 2.94 grams in 0.01150 of caffeine
Ead sulfide + oxygen lead oxide + sulfur dioxide
2 PbS(s) + 3 O2(g) 2 PbO(s) + 2 SO2<span>(g)
Hope this is what you are asking for :))</span>
Answer:
Carbon Dioxide = CO2
Explanation:
The synthesis of Malachite is seen in the chemical formula:
CuSO 4 . 5H2O(aq) + 2NaCO3(aq) --> CuCO 3 Cu(OH) 2 (s) + 2Na 2 SO 4 (aq) + CO 2 (g) + 9H 2 O(l)
The bubbles mentioned in the question hints that our interest is the compounds in their gseous phase (g).
Upon examining the chemical equation, only CO2 is in the gaseous state and hence the only one that can be formed as bubbles,
Answer:
Explanation:
First you should calculate the volume of a big sphere,so:
Then you calculate the volume of a small spehre, so:
Finally you subtract the two quantities:
Gravity depends on distance and the moon is closer to earth
