5.Which is better emulsifying agent, soap and detergent? Explain.
give me some reference about my question
Which oil is more unsaturated and has the higher melting point, safflower oil or olive oil? Explain.
The melting point of stearic acid is 70°C, and the melting point of oleic acid is 4°C. Explain in detail why their melting points are so different.
Write the equation for... and explain the reaction of the following.
a.The preparation of soap from stearic acid and NaOH.
b.The reaction of magnesium ions with sodium stearate.
Why is it that phosphoglycerides are found in cell membranes?
In the reaction Mg(OH)2 + 2HCl → MgCl2 + 2H2 O, you were given 15
grams of Mg(OH)2 and 25 grams of HCl. Which of the two reactants is the
limiting reagent? How much MgCl2 will be produced in the reaction? (Mg(OH)2
= 58.32 g/mol, HCl = 36.46 g/mol, MgCl2
= 95.32 g/mol)

how to compare the moles of product formed from each reactant
Calculate the concentration in mol dm–3 and g dm–3, of a sodium ethanedioate (Na2C2O4) solution, 5.00 cm3 of which were oxidized in acid solution by 24.50 cm3 of a potassium manganate(VII) solution containing 0.05 mol dm–3.
An ingestion tablet contains a mass of 0.30 g of magnesium hydroxide [Mg(OH)2] as its only basic ingredient. The balanced chemical equation between magnesium and hydrochloric acid (HCl(aq)), the acid produced in the stomach is as follows:
Mg(OH)2(aq) + 2HCl(aq) ⟶ MgCl2(aq) + 2H2O(l)
i)Calculate the volume of 1.00 M HCl neutralised by two of these ingestion tablets?
ii)What mass of the salt is formed in this neutralisation reaction?
How many magnesium ions are present in this amount of a salt?
