What will not speed up the rate of reaction between a strip of magnesium and hydrochloric acid?
Factors that will not speed up the rate of reaction between a strip of magnesium and hydrochloric acid include decreasing the concentration of the acid, using a larger piece of magnesium, or lowering the temperature of the reaction. These changes either reduce the frequency of collisions between reactant particles or limit the availability of reactive surface area, thus slowing down the reaction instead of speeding it up.
Would the enthalpy change be different if solid sodium hydroxide pellets were added to hydrochloric acid instead of adding hydrochloric acid to sodium hydroxide solution?
Yes, the reaction involving the solid is actually an individual step in the equation of the reaction between the solutions. If you were to add the change in enthalpy of the reaction with the solid NaOh to the change in enthalpy of the other step in the reaction (that's adding water and the NaOh pellets) you would find the sum equivalent to the change in enthalpy of the reaction involving the two solutions (this is supported by Hess's law). I suggest that you consider Hess's law for more information.
Does a magnesium metal strip rust when put in hydrochloric acid?
No, magnesium does not rust like iron does when exposed to acids. Instead, magnesium reacts with hydrochloric acid to form magnesium chloride and hydrogen gas, producing bubbles as a result of the chemical reaction.
Can you use bicarbonate soda instead of baking soda in a recipe?
No you Cant use Baking powder instead of bicarbonate of soda because if you put bicarbonate of soda into a cake mixture then you will get a very unpleasant taste !
Why there is no water formation in the neutralisation reaction between ammonia and HCl?
Water is only formed if there is oxygen atom present and in this reaction no oxygen atom is present. Rather than neutralisation it is a combination reaction in which ammonia and HCl combine to produce ammonium chloride.
Why can't sulfuric acid be used instead of hydrochloric acid in the barium chloride test?
Sulfuric acid cannot be used in place of hydrochloric acid in the barium chloride test because sulfuric acid would react with barium chloride to form insoluble barium sulfate. This would interfere with the precipitation reaction used to detect the presence of sulfates in the sample. Hydrochloric acid is preferred because it does not interfere with this reaction.
Can you use baking powder in your tropical fish tank instead of bicarbonate of soda?
sharks.
Is the sodium bicarbonate the same as sodium carbonate?
No; sodium carbonate is Na2CO3, with two sodium ions, while sodium bicarbonate is NaHCO3 and has a hydrogen ion instead of a sodium ion.
Can soda ash ie sodium carbonate be use instead of sodium bicarbonate in noodles process?
No, soda ash (sodium carbonate) should not be used instead of sodium bicarbonate in the noodles process. They have different chemical properties that can affect the texture and taste of the noodles. Sodium bicarbonate is commonly used as a leavening agent in noodles, while soda ash is not suitable for this purpose.
What is the relationship between an enzyme and the equilibrium point of reaction it catalyzes?
Enzymes do not affect the equilibrium point of a reaction they catalyze. Instead, enzymes increase the rate of reaction by lowering the activation energy barrier. The equilibrium point of a reaction is determined by the free energy difference between products and reactants at equilibrium, which remains unchanged in the presence of an enzyme.
What endothermic reaction?
An endothermic reaction is a chemical reaction in which energy (heat, light, etc.) is absorbed instead of released as in a exothermic reaction.
Why wouldn't you use potassium to make potassium chloride?
The reaction between potassium and hydrochloric acid is very violent, even explosive. On contact with the acid the reaction rapidly releases heat and hydrogen gas, which ignites. This in turn sets the potassium on fire. When this happens the potassium may explode, scattering flaming molten globules of metal.
