The option that is more likely to happen is The molar enthalpy is 447 kJ and the reaction is endothermic. We can say this <span>because decomposition reaction need more energy input than output and when this is the case, a reaction is given to be endothermic and when energy is given in, the value is positive. Hope this info can help you</span>

Cerrena [4.2K]

Answer:

Your answer will be 118 cm^3.

Explanation:

V1/T1 = V2/T2, so V2 = V1T2/T1. 60C = 333K and 120C = 393K.

V2 = (100cm3)(393K)/(333K) = 118 cm3

1.00 g of a compound is combusted in oxygen and found to give 3.14g of CO2 and 1.29 g of H2O. From these data we can tell thatA.
lora16 [44]

Answer:

the compound contains C, H, and some other element of unknownidentity, so we can’t calculate the empirical formula

Explanation:

Mass of CO2 obtained = 3.14 g

Hence number of moles of CO2 = 3.14g/44.0 g = 0.0714 mol

The mass of the carbon in the sample = 0.0714 mol × 12.0g/mol = 0.857 g

Mass of H2O obtained = 1.29 g

Hence number of moles of H2O = 1.29g/18.0 g = 0.0717 mol

The mass of the carbon in the sample = 0.0717 mol × 1g/mol = 0.0717 g

% by mass of carbon = 0.857/1 ×100 = 85.7 %

% by mass of hydrogen = 0.0717/1 × 100 = 7.17%

Mass of carbon and hydrogen = 85.7 + 7.17 = 92.87 %

Hence, there must be an unidentified element that accounts for (100 - 92.87) = 7.13% of the compound.
