Aspartame (c14h18n2o5) is a solid used as an artificial sweetener. its combustion produces carbon dioxide gas, liquid water, and
Law Incorporation [45]

Aspartame (C₁₄H₁₈N₂O₅) is a solid used as an artificial sweetener. its combustion produces carbon dioxide gas, liquid water, and nitrogen gas

C₁₄H₁₈N₂O₅ + 16O₂-----> 14CO₂ + 9H₂O + N₂.

As it can be seen from the equation, that the coefficient of nitrogen gas in the balanced equation for the reaction is 1.

So the answer here is 1 only that is coefficient of nitrogen gas in the balanced equation for the reaction is 1.

Use the IUPAC nomenclature rules to give the name for Mg(ClO4)2
Makovka662 [10]

Answer:

The answer to your question is Magnesium Perchlorate

Explanation:

IUPAC Rules to name ternary salts of chlorine

1.- Ternary salts use prefixes and suffixes it depends on the number of oxygens they have.

Example

Metal + Chlorine + 1 oxygen =  Name of the metal + hipo chlor + ite

Metal + Chlorine + 2 oxygens = Name of the metal + chlor + ite

Metal + Chlorine + 3 oxygens = Name of the metal + chlor + ate

Metal + Chlorine + 4 oxygens = Name of the metal + per + chlor + ate

For this compound the name is  Magnesium Perchlorate.

The half-cell is a chamber in the voltaic cell where one half-cell is the site of the oxidation reaction and the other half-cell
marysya [2.9K]

Answer:

\boxed{\rm \text{Fe(s) $\rightleftharpoons$ Fe$^{2+}$(aq) + 2e$^{-}$}}

Explanation:

The half-cell reduction potentials are

Ag⁺(aq) +   e⁻ ⇌ Ag(s)     E° =  0.7996 V

Fe²⁺(aq) + 2e⁻ ⇌ Fe(s)     E° = -0.447    V

To create a spontaneous voltaic cell, we reverse the half-reaction with the more negative half-cell potential.

The anode is the electrode at which oxidation occurs.

The equation for the oxidation half-reaction is

\boxed{\rm \textbf{Fe(s) $\rightleftharpoons$ Fe$^{2+}$(aq) + 2e$^{-}$}}
