<h2>Further Explanation </h2>

In chemistry, the equation of a reaction or chemical equation is the symbolic writing of a chemical reaction. The chemical formula of the reagent is written to the left of the equation and the chemical formula of the product is written to the right. The coefficient written to the left of a chemical formula is a stoichiometric coefficient, which describes the amount of that substance involved in a reaction relative to another substance. The reaction equation was first made by the iatrochemist Jean Beguin in 1615. In a reaction equation, reagents and products are connected by different symbols. The symbol → is used for one-way reactions, ⇆ for two-way reactions, and ⇌ equilibrium reactions.

Clean ionic equations are important aspects for chemistry because these equations only represent the states of matter that change in chemical reactions. This equation is commonly used in redox reactions, double replacement reactions, and acid-base neutralization. There are three basic steps to writing a clean ionic equation: balancing a molecular equation, converting it into a fully ionic equation (how each type of substance is in solution), and Determining the cations and anions in a compound.

1. equalizing molecular equations

The first step to writing a clean ionic equation is to identify the ionic compounds from the reaction. Ionic compounds are compounds that will ionize in aqueous solution and have a charge. Molecular compounds are compounds that have never had a charge. These compounds are formed from two nonmetals and are often referred to as covalent compounds.

Ionic compounds can be formed from metals and non-metals, metal and polyatomic ions, or some polyatomic ions.

If you are not sure about a compound, look for elements of the compound in the periodic table.

2. transform into a fully ionic equation

Not all ionic compounds can dissolve in aqueous solutions. Thus, the compound will not dissolve into individual ions. You must identify the solubility of each compound before continuing the rest of the equation. The following is a summary of the rules regarding solubility.

3. Determine the cations and anions in a compound

Cations are positive ions in a compound and are usually metals. Anions are nonmetal negative ions in compounds. Some non-metals can form cations, but metals will always form cations.

Answer:

HI(aq) + H₂O(ℓ) ⟶ H₃O⁺(aq) + I⁻(aq)

Explanation:

The HI donates a proton to the water, converting it to a hydronium ion

HI(aq) + H₂O(ℓ) ⟶ H₃O⁺(aq) + I⁻(aq)

Thus, the HI is behaving like a Brønsted acid.

Phosphorous pentoxide, P2O5(s), is produced from the reaction between pure oxygen and pure phosphorous (P, solid). What is the v

BartSMP [9]

Answer:

4190.22 L = 4.19 m³.

Explanation:

For the balanced reaction:

2P₂ + 5O₂ ⇄ 2P₂O₅.

It is clear that 2 mol of P₂ react with 5 mol of O₂ to produce 2 mol of P₂O₅.

Firstly, we need to calculate the no. of moles of 6.92 kilograms of P₂O₅ produced through the reaction:

no. of moles of P₂O₅ = mass/molar mass = (6920 g)/(283.88 g/mol) = 24.38 mol.

Now, we can find the no. of moles of O₂ is needed to produce the proposed amount of P₂O₅:

Using cross multiplication:

5 mol of O₂ is needed to produce → 2 mol of P₂O₅, from stichiometry.

??? mol of O₂ is needed to produce → 24.38 mol of P₂O₅.

∴ The no. of moles of O₂ needed = (5 mol)(24.38 mol)/(2 mol) = 60.95 mol.

Finally, we can get the volume of oxygen using the general law of ideal gas: PV = nRT.

where, P is the pressure of the gas in atm (P = 606.1 mm Hg/760 = 0.8 atm).

V is the volume of the gas in L (V = ??? L).

n is the no. of moles of the gas in mol (n = 60.95 mol).

R is the general gas constant (R = 0.0821 L.atm/mol.K),

T is the temperature of the gas in K (396.90°C + 273 = 669.9 K).

∴ V of oxygen needed = nRT/P = (60.95 mol)(0.0821 L.atm/mol.K)(669.9 K)/(0.8 atm) = 4190.22 L/1000 = 4.19 m³.

What is the energy change if 84.0 g of calcium oxide (CaO) reacts with excess water in the following reaction?

pochemuha

The energy change if 84.0 g of CaO react with excess water is 98KJ of heat is released.

calculation
heat = number of moles x delta H

delta H = - 65.2 Kj/mol

first find the number of moles of CaO reacted

moles = mass/molar mass
the molar mass of CaO = 40 + 16= 56 g/mol
mass = 84 g
moles therefore = 84 g/56 g/mol =1.5 moles

Heat is therefore = 1.5 moles x -65.2 = - 97.8 Kj = -98 Kj

since sign is negative the energy is released

What is formed when hydrobromic acid, hbr, and calcium hydroxide, ca(oh)2, are combined?

Lorico [155]

This is an acid – base reaction and this always result a salt and water in a neutralization reaction. 

The salt that is formed will be calcium bromide (calcium is located in group 2 so calcium bromide has a formula of CaBr2)

so essentially we got:

HBr + Ca(OH)2 ------> CaBr2 + H2O

balancing the elements: 

2HBr(aq) + Ca(OH)2(aq) --------> CaBr2(aq) + 2H2O(l)
