4 days ago · Hint: Balanced chemical equation is a chemical equation in which the number of each type of atom is equal on the two sides of the equation. The states of the chemical species should also be mentioned.
4 days ago · Now moving back to the question, we have been given a sample of 160 grams of Sodium hydroxide. The molecular formula of sodium hydroxide is NaOH. We know that the atomic weight of hydrogen is 1 amu, atomic weight of sodium is 23 amu and the atomic weight of oxygen is 16 amu. Hence the molecular weight of \[HN{O_3}\] can be calculated as ...
4 days ago · Answer. (iii) Sodium + Water → Sodium hydroxide + Hydrogen. The skeletal chemical equation of the above reaction is. Na + H 2 O → NaOH + H 2. Name of the element. No. of atoms in Reactants. No. of atoms in Product. Sodium. 1.
5 days ago · Take Free Practice Test On 2024 JAMB UTME, Post UTME, WAEC SSCE, GCE, NECO SSCE. Sodium hydroxide should be stored in properly closed containers because it ____________. A. readily absorbs water vapour from the air. B. is easily oxidized atmospheric oxygen. C. turns golden yellow when exposed to light. D. melts at low temperature.
4 days ago · The neutralization reaction between sodium hydroxide and sulphuric acid can be represented by the following chemical equation: NaOH(aq) + H2SO4(aq) → Na2SO4(aq) +H2O(l) N a O H ( a q) + H 2 S O 4 ( a q) → N a 2 S O 4 ( a q) + H 2 O ( l) Note: Neutralization reaction is a highly exothermic reaction which means that a lot of heat is evolved ...
5 days ago · We should know that, when blue litmus turns to red, it indicates that the liquid sample is acidic. Turning blue litmus red, it shows that the solution has acidity of between the pH ranges of 4.5 to 8.3. (Note that 8.3 are alkaline.) We should know that red litmus paper indicates alkalinity. By action of liquid sample on red litmus paper, if red ...
4 days ago · Kolbe’s process is a carboxylation reaction which proceeds by heating the sodium salts of phenoxide with carbon dioxide under pressure and then treated with an acid. The final product of the reaction is an aromatic hydroxy acid. If Phenol is treated with sodium hydroxide it generates sodium phenoxide ion.
