Answer:

CH₄ _{(g)}   +     2O₂_{(g)}    →      CO₂_{(g)}   +     2H₂O_{(g)}

Explanation:

This kind of reaction in which a hydrocarbon combines with oxygen gas is a combustion reaction. They are mostly used to produce heat energy that can be transformed into other forms of energy.

 Every chemical reaction is made up of reactants and products. The combining species on the left hand side are the reactant and the products are the result of the combination.

  Note: in writing chemical equations, the state of matter must always be included.

   Reactants :    Methane gas     CH₄

                          Oxygen gas        O₂

   Product:        Carbon dioxide   CO₂

                         Water vapor        H₂O

       CH₄ _{(g)}   +     2O₂_{(g)}    →      CO₂_{(g)}   +     2H₂O_{(g)}

almond37 [142]

The question is incomplete, here is the complete question:

What volume (mL) of the partially neutralized stomach acid having concentration 2 M was neutralized by 0.1 M NaOH during the titration? (portion of 25.00 mL NaOH sample was used; this was the HCl remaining after the antacid tablet did it's job)

<u>Answer:</u> The volume of HCl neutralized is 1.25 mL

<u>Explanation:</u>

To calculate the volume of acid, we use the equation given by neutralization reaction:

n_1M_1V_1=n_2M_2V_2

where,

n_1,M_1\text{ and }V_1 are the n-factor, molarity and volume of stomach acid which is HCl

n_2,M_2\text{ and }V_2 are the n-factor, molarity and volume of base which is NaOH.

We are given:

n_1=1\\M_1=2M\\V_1=?mL\\n_2=1\\M_2=0.1M\\V_2=25mL

Putting values in above equation, we get:

1\times 2\times V_1=1\times 0.1\times 25\\\\V_1=\frac{1\times 0.1\times 25}{1\times 2}=1.25mL

Hence, the volume of HCl neutralized is 1.25 mL

SCORPION-xisa [38]

Answer:

16Ag + 2C2 ---> 4 Ag4C

Explanation:

Ag + C2 ----> AgC2

The valence of Ag is one

Valence of Carbon is four

A balanced equation would be

16Ag + 2C2 ---> 4 Ag4C
