Answer:
Mg+Cl2 = Mg2+2Cl
Explanation:
Firstly balance the equation
2Mg+Cl2=Mg2+2Cl
the oxidized substance=Cl2
The symbol for the compound dinitrogen trisulfide is N2S3. It is derived from the number of nitrogen and sulfur atoms present in the compound.
The chemical compound dinitrogen trisulfide is composed of two elements: nitrogen (N) and sulfur (S). When we name the compound according to IUPAC nomenclature rules, we consider the number of each type of atom present. Dinitrogen means there are two nitrogen atoms, represented by the subscript 2, and trisulfide implies that there are three sulfur atoms, signified by the subscript 3. Hence, the symbol or chemical formula for dinitrogen trisulfide is N2S3.

Answer:
Moles of gas added = 3 moles
Explanation:
Given:
Initial volume of gas, V1 = 2.0 L
Initial moles of gas, n1 = 3 moles
Final volume, V2 = 4.0 L
To determine:
The moles of gas added to bring the final volume to 4.0 L
Explanation:
Based on the ideal gas equation
where P = pressure, V = volume ; n = moles of gas
R = gas constant, T = temperature
At constant P and T, the above equation becomes:
V/n = constant
This is the Avogadro's law
Therefore:
The final number of moles of gas = 6
Thus, moles added = Final - Initial = n2 - n1 = 6-3 = 3 moles
NaOH = 40.0 g/mol) _M
The molarity of 6.00 liters of an aqueous solution that contains 80g of sodium hydroxide is 0.33M.
Molarity = no. of moles ÷ volume
Molarity = 2mol ÷ 6L
Molarity = 0.33M
Therefore, the molarity of 2.0 liters of an aqueous solution that contains 0.50 mol of sodium hydroxide is 0.33M.

Given:
10g of potassium chlorate decomposed
STP
molar mass of KClO3 is 122.55 g/mol
Required:
Volume of oxygen gas
Solution:
The decomposition reaction is
2KClO3 → 2KCl + 3O2
Moles of O2 = 10g KClO3 (1 mol KClO3/122.55 g/mol KClO3)(3 moles O2/2 moles KClO3) = 15 moles O2
Using ideal gas law: PV = nRT
PV = nRT
V = nRT/P
V = (15 moles O2)(0.08206 L-atm/mol-K)(273K)/1 atm
V = 336.04 L O2
In the given reaction, Fe is the reducing agent and V is the oxidizing agent.
An atom or compound that loses its electrons to other substances in a reduction-oxidation reaction and gets oxidized to a higher valency state is called a reducing agent.
A reducing agent can be defined as one of the reactants of a redox reaction that reduces the other reactant by giving its electrons to the reactant. If the reducing agent can not give away its electrons to others in a reaction, then the reduction reaction cannot occur.
Given, the following chemical reaction:
2Fe + 3V₂O₃ → Fe₂O₃ + 6VO
The V₂O₃ oxidation state of V:
2 x + 3(-2) = 0
2x = 6
x = + 3
The Fe₂O₃ oxidation state of Fe:
2 y + 3 (-2) = 0
2y = 6
y = + 3
The V acts as an oxidizing agent because it accepts one electron to change the oxidation state from +3 to +2.
Fe acts as a reducing agent because it gives out its electrons to change the oxidation state from 0 to +3.
