Chemistry
1 answer:
Brrunno [24]3 years ago
5 0

Answer:

Explanation:

no of moles of water=8.00/18=0.4

1 mole of C2H6 produced 1 mole of CO2 and 1 mole of H2O

so  for 1 mole of H2O 1 mole of CO2 is produced therefore for 0.4 mole of H2O 0.4 mole of CO2  is produced

now 0.4 mole of CO2 contain how much grams=0.4*44=17.6grams

but complete combustion of 2 mole of ethane produce 4 mole of CO2 and 6 moles of H2O

so  for 6 mole of H2O 4 mole of CO2 is produced therefore  for 0.4 moles of H2O 0.27 moles of CO2 is produced

in heating a kettle of water on an electric stove, 3.34×10^3 J of thermal energy was provided by the element of the stove. yet,
insens350 [35]

Answer:

The percentage efficiency of the electrical element is approximately 82.186%

Explanation:

The given parameters are;

The thermal energy provided by the stove element, H_{supplied} = 3.34 × 10³ J

The amount thermal energy gained by the kettle, H_{absorbed}  = 5.95 × 10² J

The percentage efficiency of the electrical element in heating the kettle of water, η%, is given as follows;

\eta \% = \dfrac{H_{supplied} - H_{absorbed} }{H_{supplied}}  \times 100

Therefore, we get;

\eta \% = \dfrac{3.34 \times 10^3 - 5.95 \times 10^2}{3.34 \times 10^3}  \times 100 = \dfrac{549}{668} \times 100 \approx 82.186 \%

The percentage efficiency of the electrical element, η% ≈ 82.186%.
