<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.

How many grams of nitric acid HNO₃, are required to neutralize (completely react with) 4.30 grams of Ca(OH)2 according to the ac

Brrunno [24]

Answer:

7.32g of HNO3 are required.

Explanation:

1st) From the balanced reaction we know that 2 moles of HNO3 react with 1 mole of Ca(OH)2 to produce 2 moles of H2O and 1 mole of Ca(NO3)2.

From this, we find that the relation between HNO3 and Ca(OH)2 is that 2 moles of HNO3 react with 1 mole of Ca(OH)2.

2nd) This is the order of the relations that we have to use in the equation to calculate the grams of nitric acid:

• starting with the 4.30 grams of Ca(OH)2.

• using the molar mass of Ca(OH)2 (74g/mol).

• relation of the 2 moles of HNO3 that react with 1 mole of Ca(OH)2 .

• using the molar mass of HNO3 (63.02g/mol).

$4.30g\text{ Ca\lparen OH\rparen}_2*\frac{1\text{ mol Ca\lparen OH\rparen}_2}{74g\text{ Ca\lparen OH\rparen}_2}*\frac{2\text{ moles HNO}_3}{1\text{ mole Ca\lparen OH\rparen}_2}*\frac{63.02g\text{ HNO}_3}{1\text{ mole HNO}_3}=7.32g\text{ HNO}_3$

So, 7.32g of HNO3 are required.

What is the mass of CO2 lost at 20 min from the limestone sample?

harkovskaia [24]

Answer:

The mass, CO2 and CO3 from the limestone sample is discussed below in details.

Explanation:

(A) mass loss of sample of limestone after 20 min

= 0.8437g-0.5979g = 0.2458 g

From the given reaction of limestone, 2 mol of the sample gives 2 moles of CO 2.

Therefore

184.4 g ( molar mass of limestone) gives2× 44 g of carbon dioxide.

1 g of sample gives 88/184.4 g of carbon dioxide

Hence 0.2458 g sample gives

= 88/184.4 × 0.2458 g = 0.117 g carbon dioxide

(B) mole of CO 2 lost = weight/ molar mass

= 0.117 g / 44 g/mol =0.0027 mole

(C). 1 mol of limestone contain 2 mol of carbonate ion

From the reaction we know that carbonate ion of limestone is converted into carbondioxide

Hence lost carbonate ion = 0.2458 g

(D) we know that

1 mol limestone contain 1mol CaCO 3

Hence in sample present CaCO 3

= 1mole / 184.4 g × 0.8437 g= 0.00458 mol CaCO3

Which of the following scientists made an important contribution to quantum mechanics: (i) Bohr (ii) deBroglie (iii) Heisenberg

grandymaker [24]

Answer:

(i) Bohr; (ii) de Broglie; (iii) Heisenberg (v) Schrödinger

Explanation:

(i) Niels Bohr — 1913 — proposed that electrons travel in fixed orbits with quantized energy levels and that they jump from one energy level to another by absorbing or emitting quanta of light.

(ii) Louis de Broglie — 1924 — proposed the wave nature of electrons and suggested that all matter behaves as both waves and particles (wave-particle duality).

(iii) Werner Heisenberg — 1927 — formulated quantum mechanics in terms of matrices and proposed his famous uncertainty principle.

(v) Erwin Schrödinger — 1926 — applied wave mechanics to the electron in a hydrogen atom, showing that electrons exist in orbitals rather that orbits.

(iv) Ernest Rutherford — 1911 — proposed that atoms have most of their mass in a central nucleus (nuclear atom). Quantum mechanics had not yet been invented.

Identify the products of a reaction under kinetic control. a. The most stable product. b. The product whose formation requires t

aleksley [76]

Answer: Option (b) and (d) are the correct answer.

Explanation:

Kinetic products are defined as the products which contain a terminal double bond and the reaction is irreversible in nature.

Kinetic controlled products are formed faster because these tend to lower the activation energy. Due to this molecules with less energy are also able to participate in the reaction.

Therefore, rate of reaction increases leading to rapid formation of products.

Therefore, we can conclude that the products of a reaction under kinetic control are product that is formed at the fastest rate and product whose formation requires the smallest free energy of activation.
