Which do you expect to be more reactive, lithium or potassium? Explain. Describe and explain the stereochemistry of the peroxoborate ion. Explain why water "wets" some surfaces and beads up on others, while mer
(a) (i) zinc displaces copper / zinc more reactive than copper; [1] Zn + CuCl2→ ZnCl2 + Cu / Zn + Cu2+ →Cu + Zn2+; [1] (ii) less steep(line) or lower gradient /(because of) decreased rate; [1] ethanoic is a weak(er) acid / only partially ionised / dissociated / ...
What is a chelate? What do lithium, sodium and potassium have in common? Which cation is more strongly hydrated, Fe3+ or Fe2+? Explain. State whether water is polar or non polar. Also explain its consequence on properties of water as solvent. What is the difference between toluene and xy...
To answer the question about which elements occupy the peaks in the Lothar-Meyer curve, we can follow these steps:1. Understanding the Lothar-Meyer Curve: - The Lothar-Meyer curve is a graphical representation that plots at
Thus, racemate 1 was separated into its enantiomers 1a and 1b, with subsequent tests demonstrating that 1a is the physiologically relevant enantiomer (hLH-R ∼17 times, rLH-R ∼12 times more active than 1b). We were able to obtain diffracting crystals of a closely related derivative of...
Name the gas evolved in each of the following cases : Zinc sulphide is treated with dilute hydrochloric acid. View Solution Which gas is released when Potassium reacts with dilute hydrochloric acid? View Solution Identify the gas evolved in the following reactions when : ...
Such nitrate salts may typically include: nitrate salts of alkali metals such as lithium, sodium, or potassium; nitrate salts of the alkaline earths such as magnesium and calcium; nitrate salts of metals with more than one valence state such as chromium, manganese, iron, cobalt, nickle, or ...
Examples of aqueous bases suitable for development are aqueous solutions of lithium, sodium or potassium hydroxide or of lithium, sodium or potassium carbonate or bicarbonate or of ammonia. Examples of suitable aqueous alcoholic developers are aqueous solutions which contain minor amounts of methanol, ...
The reactive dyes represented by formulas I and II are used in the form of a free acid or a salt, particularly an alkali metal salt or an alkaline earth metal salt, more particularly a sodium salt, a potassium salt or a lithium salt. To obtain a liquid composition, a lithium salt is ...
