C because ships and other boats has underwater microphones underwater because on most cargo ships the engine is to loud so they use microphones underwater to detect torpedos so your answer is C
Answer:
16.02 g
Explanation:
the balanced equation for the decomposition of CuCO₃ is as follows
CuCO₃ --> CuO + CO₂
molar ratio of CuCO₃ to CO₂ is 1:1
number of CuCO₃ moles decomposed - 45 g / 123.5 g/mol = 0.364 mol
according to the molar ratio
1 mol of CuCO₃ decomposes to form 1 mol of CO₂
therefore 0.364 mol of CuCO₃ decomposes to form 0.364 mol of CO₂
number of CO₂ moles produced - 0.364 mol
therefore mass of CO₂ produced - 0.364 mol x 44 g/mol = 16.02 g
16.02 g of CO₂ produced
Answer:
a
Explanation:
because na + has 11 electrons and has a higher chance to give away one then to gain 7 more. so the answer is a
3 C6H12O6,
C=3*6=18 Carbon atoms
H=3*12=36 Hydrogen atoms
O=6*3=18 Oxygen atoms
0.86 moles of CO2 - i’m not sure if this is right but it should be something like that
