Write the word, formula, and chemical equations for the reaction between hydrogen sulfide gas and oxygen gas that produces sulfu
evablogger [386]

Answer:

The balanced equations for the reactions are outlined below:

Explanation:

A balanced equation describes how many (number of moles) atoms of the reactant give rise to how many (number of moles) of product.

  1. Hydrogen sulfide gas (H_{2}S) and oxygen gas (O_{2}) react to produce sulfur dioxide gas (SO_{2}) and water vapor gas.
  2. The balanced equation for the reaction, taking into consideration the states is:

    2H_{2}S(g) + 3O_{2}(g) → 2SO_{2}(g) + 2H_{2}O(g)

Vanadium(II) oxide (VO) is oxidized by iron(III) oxide (Fe2O3) resulting in the formation of vanadium(V) oxide (V2O5) and iron(II) oxide (FeO).

The balanced equation:

2VO + 3Fe_{2}O_{3} → V_{2} O_{5}  + 6FeO

If the rate law for a reaction A → P is rate = 3.37x10-3 M^-1 min-1 [A]^2 and the initial concentration of a is 0.122 M, calcula
DedPeter [7]

Rate = 3.37x10-3 M^-1 min-1 [A]^2 and the initial concentration of a is 0.122M.

A rate law indicates the rate of a chemical response depends on reactant concentration. For a response inclusive of the price regulation commonly has the form rate = ok[A]ⁿ, in which okay is a proportionality constant known as the fee regular and n is the order.

The charge of a chemical response is, perhaps, its maximum crucial asset because it dictates whether or not a reaction can arise all throughout an entire life. knowing the charge regulation, an expression concerning the price to the concentrations of reactants can assist a chemist to modify the response conditions to get an extra suitable rate.

half-life is the time taken for the radioactivity of a substance to fall to 1/2 its authentic cost whereas implies existence is the common life of all the nuclei of a particular risky atomic species.

Consider three 1 L flasks at STP. Flask A contains NH3 gas, flask B contains NO2 gas, and flask C contains N2 gas. Which contain
diamong [38]
1 mole of gas occupies 22.4 L at STP. Therefore, each gas has 1/22.4 moles and because the number of moles is the same, the number of molecules of each gas is also the same.

The least polar molecules are of N₂ and they will show the most ideal behavior out of all three of the gases.
