4 days ago · The enthalpy is about 57.kJ/mol. The reaction is shown below, \[NaOH\,\, + \,\,HCl \to NaCl\,\, + {H_2}O\] So, the product of this reaction is Sodium chloride + Water + Heat So, the correct answer is B. Additional information: Sodium acetate is the sodium salt of acetic acid, which can be formed by the reaction of sodium hydroxide which is a ...
4 days ago · Pure sulfuric acid has a specific gravity of 1.830 at 25 °C (77 °F); it freezes at 10.37 °C (50.7 °F). When heated, the pure acid partially decomposes into water and sulfur trioxide; the latter escapes as a vapour until the concentration of the acid falls to 98.3 percent. This mixture of sulfuric acid and water boils at a constant ...
4 days ago · Hint: We have to know the laboratory preparation of alkanes from salts of carboxylic acids is decarboxylation reaction. In the process of decarboxylation, carbon dioxide is removed from the molecules containing $ - COOH$ group. We can get alkane when saturated monocarboxylic acid salt of sodium/potassium undergoes dry distillation with soda lime.
3 days ago · When ferric chloride ( $ FeC{l_3} $ ) reacts with sodium hydroxide it forms a precipitate of ferric hydroxide. The reaction can be represented as – $ FeC{l_3} + 3NaOH \to Fe{(OH)_3} \downarrow + 3NaCl $ We can see here that to balance the Valency of ferric ions three moles of hydroxide ions are needed.
5 days ago · (ii) Write a balanced chemical equation to illustrate the reaction of chlorine gas with cold dilute sodium hydroxide. (c) In a certain reaction, 15.0 g of impure magnesium sample reacted with excess hydrochloric acid liberating 8.6 dm\(^2\) of hydrogen gas at s.t.p. (i) Write a balanced equation for the reaction.
4 days ago · According to the above discussion, we conclude when \[C{l_2}\]gas reacts with hot and concentrated sodium hydroxide solution, the oxidation number of chlorine changes from Zero to \[ - 1\] and zero to\[- 3\]. Hence, option A is the correct answer. Note: We have to know that halogen is the most electron affinity group in the periodic table.
4 days ago · So, sodium hydrogen carbonate is a basic salt. When we strongly heat sodium hydrogen carbonate then it produces sodium carbonate, water and carbon dioxide as the by-product of the reaction. We can write the chemical equation for this reaction as, $2NaHC{O_3}\xrightarrow{\Delta }N{a_2}C{O_3} + {H_2}O + C{O_2}$ b.
