What is a double replacement reaction? How are they . . . - Socratic The clue lies in the name itself Double displacement reactions occur when two ionic compounds react, or when an ionic compound reacts with an acid It only occurs in liquids There are 5 types of double displacement reaction, as shown below: Salt + salt = insoluble salt + salt Acid + carbonate = salt + H2O + CO2 Acid + base = salt + H2O Ammonium + hydroxide = salt + H2O + NH3 Acid + sulfite
Why is H_2 not very soluble in water? | Socratic The trade in energy sucks for H2 (but not so much for water), so the H2⋯H2O interaction is highly unfavored for H2, compared to the H2⋯H2 and H2O⋯H2O interactions So, H2 is very poorly soluble in water Its solubility at 1 atm at 20∘C is 0 00016 g H2 100 g water
Which solution has the highest osimatic pressure? (a) 2g . . . - Socratic Should it not be d ? The number of particles in solution DETRACT from the osmotic pressure And so the LESSER the amount of solute, the LESSER the detraction from osmotic pressure with respect to the pure solvent Of course, we assume the SAME solute in each scenario and thus mass is a good approximation of the number of particles in solution
Site Map - Percent Concentration Questions and Videos | Socratic Given the following equation: C6H8O7 + 3NaOH --> Na3C6H5O7 + H2O What is the percentage by mass of citric acid in the orange juice? How many grams of HCI are there in 100 0 mL of concentrated HCl which is approximately 12 1M and 37% HCl by weight and the density of 1 191 g mL?
