Let's write the reaction first.
HCl + H₂O ---> H₃O⁺ + Cl⁻
These reaction has two reactants, either the proton donor or the proton acceptor. Water is amphoteric, meaning it can act as an acid or base. Since HCl is an acid, then water in this reaction acts as a base.
1. The proton donor is HCl because it donates H+ to water which yields a hydronium ion, H₃O⁺.
2. The proton acceptor is water.
Answer:
3 (c)
Explanation:
All matter has density becuase all matter takes up space. When you wave your hand infront of yourself you feel wind. if air did not take up space it would all collapse into a black hole becuase their would be no resistance.
Wolf gang polli made the polli exlution princible, it says that all fermion particles take up space and can not be in the same place at the same time. This is why your legs hold up, your Piano doesent fall through the ground. if this wassent true everything would collaps into a black hole
Hope it helped
Answer:
lower layer
Explanation:
Usually to identify halide ions in solution you use silver nitrate which readly react with Cl⁻, Br⁻ and I⁻ ions to form silver halide salts with different colors depending on the ion present in the solution.
Now, because the silver halide salts are insoluble in water and have a density higher that the water they will stay in the lower part of the test tube.
<u>Answer:</u> The heat of formation of oleic acid is -94.12 kJ/mol
<u>Explanation:</u>
We are given:
Heat of combustion of oleic acid =
The chemical equation for the combustion of oleic acid follows:
Enthalpy change is defined as the difference in enthalpies of all the product and the reactants each multiplied with their respective number of moles. It is represented as
The equation used to calculate enthalpy change is of a reaction is:
The equation for the enthalpy change of the above reaction is:
We are given:
Putting values in above equation, we get:
Hence, the heat of formation of oleic acid is -94.12 kJ/mol
Ch2o is the empirical formula of the substance.
