A mixture of hydrocarbons contains 34.8% heptane, C7H16, 10.1% nonane, C9H20, and 55.1% octane, C8H18. The mixture is combusted
Zinaida [17]
<h3>Mass of CO₂ generated from the combustion : 14.277 kg</h3><h3>Further explanation</h3>

Mass Heptane : 0.348 x 17 = 5.916 kg

mass C in Heptane (MW=100.21 g/mol) :

\tt \dfrac{7.12}{100.21}\times 5.916=4.959~kg

Mass Nonane : 0.101 x 17 = 1.717 kg

mass C in Nonane (MW=128.2 g/mol) :

\tt \dfrac{9.12}{128.2}\times 1.717=1.446~kg

Mass Octane : 0.551 x 17 = 9.367 kg

mass C in Otane (MW=114.23 g/mol) :

\tt \dfrac{8.12}{114.23}\times 9.367=7.872~kg

Total mass produced :

4.959+1.446+7.872=14.277 kg

Why earth not flat and why we live in this country not yours
bagirrra123 [75]

Answer:

Earth is not flat because the spheroidical shape provides a more effective shape in terms of exposed surface area for absorbing and radiating radiation, and also for a relatively more uniform gravity pull on different points on its surface which might not be so for a flat surface.

You live in your country, not mine because you have evolved over time to be more adapted to living in your own kind of envoirment. Members of a certain species (like you and me as humans) have been spread to maximize the survivability of their species compared to if they were clustered to a particular place.

A bowling ball is pushed with a force of 22.0 N and accelerates at 5.5m/s. What is the mass of the bowling ball
Luden [163]
Hello!

Data:

F (force) = 22.0 N
m (mass) = ? (in Kg)
a (acceleration) = 5.5 m/s²

We apply the data to the Resultant Force formula, we have:

F =m*a

22 = m*5.5

5.5 m = 22

m =  \dfrac{22}{5.5}

\boxed{\boxed{m = 4\:Kg}}\end{array}}\qquad\checkmark

I hope this helps. =)
