44g per mole of CO2(1 mole=44g)
Answer:
4. gives the relative number of atoms of each element per formula unit
Explanation:
An empirical formula -
It refers to the formula which determined the simplest whole - number ratio of all the atoms in a given species , is referred to as an empirical formula .
In simple terms ,
It is he smallest formula of the whole number which when multiplied by some whole number gives the actual structure of the compound .
Hence , from the given information of the question ,
The correct option for empirical formula is 4.
The silver chloride electrode usually functions as a redox electrode where the equilibrium is achieved between silver and its salt (silver chloride).
The half reaction for this electrode is as follow:
<span>AgCl(s)+e−→Ag(s)+Cl−(aq) where:
</span>(s) refers to solid state
(aq) refers to the aqueous state and
e- is the electron
I believe it might be A. Damaged buildings.
B is a positive and so is Tourism.
Answer:
4 Ag⁺ + 2 H₂O + BrO⁻ → 4 Ag + BrO₃⁻ + 4 H⁺
Explanation:
In order to balance a redox reaction, we will use the ion-electron method.
Step 1: Identify both half-reactions
Reduction: Ag⁺ → Ag
Oxidation: BrO⁻ → BrO₃⁻
Step 2: Perform the mass balance adding H⁺ and H₂O where necessary
Ag⁺ → Ag
2 H₂O + BrO⁻ → BrO₃⁻ + 4 H⁺
Step 3: Perform the electrical balance adding electrons where necessary
1 e⁻ + Ag⁺ → Ag
2 H₂O + BrO⁻ → BrO₃⁻ + 4 H⁺ + 4 e⁻
Step 4: Multiply both half-reactions by numbers that secure that the number of electrons gained and lost are equal
4 × (1 e⁻ + Ag⁺ → Ag)
1 × (2 H₂O + BrO⁻ → BrO₃⁻ + 4 H⁺ + 4 e⁻)
Step 5: Add both half-reactions
4 e⁻ + 4 Ag⁺ + 2 H₂O + BrO⁻ → 4 Ag + BrO₃⁻ + 4 H⁺ + 4 e⁻
4 Ag⁺ + 2 H₂O + BrO⁻ → 4 Ag + BrO₃⁻ + 4 H⁺
