Answer:- 6984 kJ of heat is produced.
Solution:- From given information, 1367 kJ of heat is produced by the combustion of 1 mole of ethanol. We are asked to calculate the heat produced by the combustion of 235.0 g of ethanol.
Let's convert given grams to moles and multiply by the heat produced by one mole of ethanol to get the total heat produced. Molar mass of ethanol is 46 grams per mole. The set will be:
= 6984 kJ
So, 6984 kJ of heat is produced by the combustion of 235.0 g of liquid ethanol.
3,91·10²⁴ = 39,1·10²³
-----------------------------
110,96g ----------- 6,02·10²³ molecules
Xg ------------------ 39,1<span>·10²³ molecules
X = (110,96</span>×39,1·10²³)/<span>6,02·10²³
<u>X = 720,687g</u>

There are two<span> types of </span>comet tails<span>: dust and gas ion. A dust </span>tail<span> contains small, solid particles that are about the same size found in cigarette smoke. This </span>tail<span> forms because sunlight pushes on these small particles, gently shoving them away from the </span>comet's<span> nucleus.</span>
The valency of an atom is equal to the number of electrons in the outer shell if that number is four or less. Otherwise, the valency is equal to eight minus the number of electrons in the outer shell. Once you know the number of electrons, you can easily calculate the valency.
