Answer:

C2H5OH(l) +3O2(g) → 2CO2(g) + 2H2O(l)

it is combustion reaction and heat is also produced.

Explanation:

This is oxidation reduction reaction which is also called redox reaction.

C2H5OH  is reducing agent while O2 is oxidizing agent.

Chemical equation:

C2H5OH + O2 → CO2 + H2O

Now we will balance the equation. In given chemical equation two carbon atoms on the left side and one carbon atom on the right side. While six hydrogen atoms are present on the left and just two hydrogen on right side. We will write coefficient two with carbon dioxide and and three with water molecules.

C2H5OH + O2 → 2CO2 + 3H2O

now we will balance the oxygen atoms. we can see there are three oxygen atoms on the left and seven on right side. we will write coefficient three with oxygen on left and equation becomes balance.

C2H5OH + 3O2 → 2CO2 + 3H2O

Complete chemical equation with physical states:

C2H5OH(l) + 3O2(g) → 2CO2(g) + 3H2O(l)

Convection - hot air rises, cold air sinks
Insulation - to insulate or capture heat
Radiation - by waves
Direct contact means touch, therefore the answer would be conduction.

As temperature increase and the volume stays constant, how will the pressure change
crimeas [40]

Answer:

There will be more collisions and so a greater pressure. The number of particles is proportional to pressure, if the volume of the container and the temperature remain constant. ... Volume is inversely proportional to pressure, if the number of particles and the temperature are constant.

How can you tell what is what and how that what affects what
VLD [36.1K]

Answer:

Hi, this is a super vague question, so its pretty confusing to answer.  Could you please be a bit more specific?

If you are referring to chemistry, then how you tell "what is what" is by the molecular makeup of an element (Periodic table), and "how that..affects what", chemical reactions can occur between elements
