The answer is C. statement of owner's equity
Explanation:
723.4 it's 723.4 cuz 2.40+721.0 = 723.4
Answer:
D) dependent on the element that reacted with carbon.
Explanation:
Nuclear fusion involves the combination of small atomic nuclei to form larger ones. This combination or fusing of nuclei is always accompanied by the release of large amount of energy.
The fusion product depends on the combining elements that fuses together. As we would have it, the fusion results in the formation of a heavier nuclei. Therefore, the combination of the Carbon and the other element would yield another nuclei that is heavier.
Molar mass O2 = 31.99 g/mol
Molar mass CO2 = 44.01 g/mol
Moles ratio:
<span>C3H8 + 5 O2 = 3 CO2 + 4 H2O
</span>
5 x 44.01 g O2 ---------------- 3 x 44.01 g CO2
( mass of O2) ------------------ 37.15 g CO2
mass of O2 = 37.15 x 5 x 44.01/ 3 x 44.01
mass of O2 = 8174.8575 / 132.03
mass of O2 = 61.916 g
Therefore:
1 mole O2 ----------------- 31.99 g
moles O2 -------------------- 61.916
moles O2 = 61.916 x 1 / 31.99
moles = 61.916 / 31.99 => 1.935 moles of O2
In a hot gas, the molecules move faster than in a cold gas; the mass remains the same, but the kinetic energy, and hence the temperature, is greater because of the increased velocity of the molecules. ... We can sense that one gas is hotter than another gas and therefore has a higher temperature.
