What’s the balanced equation of sodium hydroxide + carbon dioxide produces sodium carbonate + water?

Hemoglobin in your blood does not use elemental iron. It uses iron in the form of Fe2+(aq).

valina [46]

Explanation:

Balanced chemical reaction equation will be as follows.

$2Fe^{2+}(aq) + 2H^{+}(aq) \rightleftharpoons 2Fe^{3+}(aq) + H_{2}(g)$

In human body, the neutral iron changes into $Fe^{2+}$ (aq) cation. There will be an oxidation-half reaction and a reduction-half reaction. Equations for this reaction are as follows.

Oxidation: 2Fe^{2+}(aq) \rightleftharpoons 2Fe^{3+}(aq) + 2e^{-}[/tex] .... (1)

Reduction: $2H^{+}(aq) + 2e^{-} \rightleftharpoons H_{2}(g)$ ...... (2)

On adding both equation (1) and (2), the overall reaction equation will be as follows.

$2Fe^{2+}(aq) + 2H^{+}(aq) \rightleftharpoons 2Fe^{3+}(aq) + H_{2}(g)$

Therefore, neutral iron is a part of Heme - b group of Hemoglobin and in an aqueous solution it dissolutes as a part of Heme group. Hence, then it becomes an $Fe^{2+}$ cation.

The table below shows the number of sub-atomic particles in an atom of sodium. Sub-atomic Particles Sub-atomic Particle Number P

AlexFokin [52]

Answer is: the amu of a sodium atom is 23.

The unified atomic mass unit (amu) is a standard unit of atom mass.

One unified atomic mass unit is approximately the mass of one nucleon (proton or neutron).

The unified atomic mass unit is equal 1.66·10⁻²⁷ kg.

n(p⁺) = 11; number of protons in sodium atom.

n(n°) = 12; number of neutrons of sodium atom.

n(p⁺ + n°) = 11 + 12.

n(p⁺ + n°) = 23; number of nucleons in sodium atom.

Write the balanced molecular chemical equation for the reaction

Ierofanga [76]

The balanced molecular chemical equation for the reaction will be expressed as Cs₂CO₃ + Mg(NO₃)₂ -> 2CsNO₃ + MgCO₃

For any chemical equation to be balanced, the number of moles of elements in the reactants must be equal to that of the product.

According to the question, we are to write a balanced equation for the reaction in aqueous solution for cesium carbonate and magnesium nitrate

The chemical formula for Cesium carbonate is Cs₂CO₃

The chemical formula for magnesium nitrate is Mg(NO₃)₂

Hence the balanced molecular chemical equation for the reaction will be expressed as Cs₂CO₃ + Mg(NO₃)₂ -> 2CsNO₃ + MgCO₃

Pls help

Irina-Kira [14]

Answer:

CrO₂ --------------------> Cr⁴⁺ and O²⁻

VCO₃ -------------------> V²⁺ and CO₃²⁻

Cr₂(SO₄)₃ -------------> Cr³⁺ and SO₄²⁻

(NH₄)₂S ----------------> NH₄⁺ and S²⁻

Explanation:

Within ionic compounds, the cation is listed first, followed by the anion. Some of the ions are polyatomic, meaning they are covalently bonded to other elements. Polyatomic ions always have a specific charge.

All of these ionic compounds have an overall charge of 0. As such, the charges of the cations and anions must balance out. In order to do so, there are some compounds which have more than one atom of each ion.

2.) CrO₂

------> Oxygen (O) always forms the anion, O²⁻.

------> Therefore, if there are 2 oxygen anions, the chromium (Cr) must have the cationic form of Cr⁴⁺.

------> +4 + (-2) + (-2) = 0

3.) VCO₃

------> Carbonate (CO₃), a polyatomic ion, always has the state CO₃²⁻.

------> If there is only one atom of each ion, the charges must perfectly balance, making vanadium (V) be the cation V²⁺.

------> +2 + (-2) = 0

4.) Cr₂(SO₄)₃

------> Sulfate (SO₄), a polyatomic ion, always has the state SO₄²⁻.

-------> The only way the charges could balance out is if the chromium (Cr) is in the cationic form Cr³⁺.

------> +3 + 3 + (-2) + (-2) + (-2) = 0

5.) (NH₄)₂S

------> Ammonium (NH₄), a polyatomic ion, always has the state NH₄⁺.

------> Sulfur (S) always forms the anion S²⁻.

------> +1 + 1 + (-2) = 0
