How many miles of co2 are emmited into the atmosphere when 11.6g of c8h18 is burned?

0.816 mole

Explanation:

To solve this problem, first, we need to balance the equation. The balance equation is given below:

2C8H18 + 25O2 —> 16CO2 + 18H2O

Next, let us covert 11.6g of C8H18 to moles. This is illustrated below:

Molar Mass of C8H18 = (12x8) + (18x1) = 96 + 18 = 114g/mol

Mass of C8H18 = 11.6g

Number of mole = Mass /Molar Mass

Number of mole of C8H18 = 11.6/114

Number of mole of C8H18 = 0.102mole.

Now we can easily find the number of mole of CO2 emitted as shown below:

From the balanced equation,

2 moles of C8H18 produced 16 moles of CO2.

Therefore, 0.102mole of C8H18 will produce = (0.102x16)/2 = 0.816mole of CO2.

Therefore, 0.816 mole of CO2 are emitted.

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
