Sodium is the reducing agent because a reducing agent is always the donor of electrons.
Answer:
Combustion reaction
Explanation:
Let's consider the following balanced equation.
CH₄ + 2 O₂ ⇒ CO₂ + 2 H₂O
This reaction is known as a combustion reaction, in which a compound reacts with oxygen to form a compound of carbon and water.
- If the product is carbon dioxide, the combustion is complete.
- If the product is carbon monoxide or carbon, the combustion is incomplete.
Answer:
everything (matter) is made up of molecules(atoms)
Explanation:
Option 2: 12.0 L of 
at STP.
The standard pressure and temperature values are 1 atm and 273.15 K.
Using the ideal gas equation, number of moles of gas can be calculated which is as follows:
PV=nRT...... (1)
Here, P is pressure, V is volume, n is number of moles, R is gas constant and T is temperature.
Also, in 1 mole of any gas there are 
molecules of the gas. This is known as Avogadro's number and denoted by symbol 
Thus,
Equation (1) can be rewritten as follows:
On rearranging,
Here, all the other terms are constant except volume, thus, gas with volume equal to the volume of 
will have same number of molecules.
Volume of gas and 
gas is same thus, will have same total number of molecules as gas.
It might be physical forces
