Answer:
C2H4O2 + 2O2 —> 2CO2 + 2H20
The coefficients are 1, 2, 2, 2
Explanation:
C2H4O2 + O2 —> CO2 + H20
To balance the above, do the following
Since there are 2 carbon on the left, put 2 in front of CO2, we have
C2H4O2 + O2 —> 2CO2 + H20
We have 4 hydrogen on the left, to balance it put 2 in front of H2O i.e
C2H4O2 + O2 —> 2CO2 + 2H20
Now, we have a total of 6 oxygen on the right side. To balance it, put 2 in front of O2:
C2H4O2 + 2O2 —> 2CO2 + 2H20
The coefficients are 1, 2, 2, 2
Answer:

Explanation:
<em>Specific Heat:</em><em> </em>The specific Heat of any material is the heat absorbed or evolved by the material to raise or fall it's temperature by 1°C per unit mass of the material.
The heat absorbed or evolved (Q) is directly proportional to the mass of substance(m) and rise or fall of temp(∆T)
The general formula for specific heat is,

Where
- s is specific heat,
- Q is the Heat absorbed or evolved
- m is mass of substance
- & ∆T is change is temperature
<em>Now coming to your question,</em>
<em>The specific heat of Aluminium is 897 J/kg °C</em>
<em>The specific heat of Aluminium is 897 J/kg °C& specific heat of methanol is 2450 J/kg ° C</em>
The definition states that, <u>if the specific heat would be more, more amount of heat will be required for per unit change in temperature.</u>
The specific heat of Aluminium is 897 J/kg °C which means for one kilogram aluminium, 897 Joule energy is required to change it's temperature by 1°C & Similarly for one kilogram methanol 2450 joule energy is required.
Hence, the correct answer would be methanol!

The Balanced Reaction is 2N₂O₃⁻ -----> 2 N₂ + 3 0₂
<h3>What is a Balanced Reaction ?</h3>
A reaction in which the number of atoms of each element in the reactant and the product are equal is called a Balanced Reaction .
It is given in the question:
To Balance the chemical equation.
N₂O₃⁻ -----> N₂ + 0₂
To balance the reaction , the number of molecules of each element , i.e. Nitrogen (N) and Oxygen (O) needs to be balanced
2N₂O₃⁻ -----> 2 N₂ + 3 0₂
