write a balanced chemical equation to represent and aqua sodium hydroxide solution that is added to a copper sulphate solution forms a bluish white precipitate of copper hydroxide |
Answer» Answer :-It is given that aqueous SODIUM HYDROXIDE (NaOH) solution is added to copper sulphate solution (CuSO₄) , and forms a bluish white precipitate i.e. Copper Hydroxide [Cu(OH)₂] . Another product, which is formed in this REACTION is aqueous solution of Sodium Sulphate (Na₂SO₄) . NaOH + CuSO₄ → Cu(OH)₂ + Na₂SO₄ [skeletal equation] ______________________________ On observing the above equation carefully, we will understand that the equation will be balanced if we multiply "NaOH" on the REACTANT side with 2 . 2NaOH + CuSO₄ → Cu(OH)₂ + Na₂SO₄ [balanced equation] . The obtained balanced equation will be more informative if we add "symbols of physical states" of the reactants and the products. So, here we write it :- 2NaOH (AQ) + CuSO₄ (aq) → Cu(OH)₂ (s) + Na₂SO₄ (aq) |

Pls calculate the n- factor of this reactionP4 + OH- ----> PH3 + H2PO2THANK YOU☺️☺️ |
|
Answer» Explanation: elemental phosphorus is both OXIDIZED and reduced… 14P4+3H++3e−→PH3REDUCTION: P(0) → P(-III): But basic conditions were specified…so we add three equiv hydroxide to each side… 14P4+3H2O+3e−→PH3+3HO−Oxidation: P(0) → P(-III): 14P4+2HO−→P(OH)+2+3e−Oxidation: P(0) → P(+III): Note that you got the wrong charge in your question… We add the oxidation reaction to the reduction equation to get… 12P4+3H++2HO−→P(OH)+2+PH3 And we CLEAN this up to get… 12P4+H++2H2O→P(OH)+2+PH3 |

If the valency of sodium is 1 and oxygen is 2, then the formula of compound formed between sodium and oxygen is? |
|
Answer» Hint: Chemical formula is an expression that is used to denote the number and types of elements that are PRESENT in one molecule of a compound. The chemical formula of sodium oxide contains two sodium atoms and one oxygen atom. Complete step-by-step answer: Sodium oxide is an ionic compound made up of sodium ions and oxide ions. As we know that the electronic configuration of Na is 2,8,1. Since only one electron is present in the outermost shell or valence shell. Hence, its valency is +1. The electronic configuration of oxygen is 2,6. Since SIX electrons are present in the outermost shell, so to calculate the valency for atoms 4 or more than four we have to subtract it from 8. So, the valency of oxygen should be (8−6) = 2. Explanation: MARK as BRAINLIEST. |

What are the characteristics of negative ionic vacancy defects? |
|
Answer» Answer: It is a BOND formed by the complete transfer of electrons from one atom to other Physical state: solid at room temperature Crystal structure: positive and negative ions are arranged in Crystal lattice Hard with high melting and boiling POINTS: due to strong electrostatic forces Conductivity: conductors in the MOLTEN or aqueous state but insulators in solid-state. Solubility in water: ionic compounds are soluble in water due to polar nature of water and high dielectric constant, if hydration energy is more than lattice energy then ionic compounds is soluble, but are insoluble in non-polar solvents. Ionic reactions: fast reactions which involve the only transfer of electrons, no bond DISSOCIATION or formation. Firstly READ This Carefully Then Write On Your NotebookPlease Mark Me As Brilliant |
