To convert from moles to atoms you times the number of mols by Avogadro's number (6.022×10²³)
0.74 × 6.022×10²³ = 4.45628×10²³
Answer: 2 C2H4 + 6 O2 => 4 CO2 + 4 H2O
Explanation:The coefficient are as follows: 2: 6: 4: 4
Each atom on the reactant and product side are equal.
Reactant Product
C 2x2 = 4 4x1 = 4
H 2x4 = 8 4x2 = 8
O 6x2 = 12 (4x2) + 4 = 12
Lol. It is now a solution and not really inseparable, so your only logical option would be to throw it away and try again.
Precision relates to how close the answers are to each other, so I’d think it would be D because of the limited range between data points.
Answer:
Explanation:
Hello there!
In this case, since the thermodynamic definition of heat in terms of mass, specific heat and temperatures is given by:
We are to calculate the specific heat of the ethanol as shown below:
Thus, by plugging it the given data we can obtain:
Regards!
