Which statement about the second experiment is correct.
Marble chips and nitric acid experiment.
One for concentrated hno3 has no2 nasty nitrogen dioxide as a product while the other for dilute hno3 has not.
The rate of this reaction can be changed by changing the size of the marble chips.
Using the apparatus shown the change in mass of carbon dioxide can be measure with time.
My guess is that the answer would vary depending on the concentration of the nitric acid.
Marble is especially sensitive to the degrading by acidic chemicals also to weathering.
3m hydrochloric acid with large marble chips 1 5m hydrochloric acid with small marble chips 3m hydrochloric acid with small marble chips a reading was taken initially every 15 seconds for a minute and then every 30 seconds for the next 4 minutes.
Calcium chloride solution is also formed.
All other conditions remain the same.
Marble chips react with dilute hydrochloric acid to produce carbon dioxide gas.
15 in an experiment nitric acid is added to excess marble chips and the volume of carbon dioxide formed is measured.
Place 40cm 3 of hydrochloric acid in an conical flask.
Acid rain contains carbonic acid nitric acid and sulphuric acid co2 no2 and so2.
The reason i think it would vary is that you get different reactions when one puts pure copper in either concentrated or dilute nitric acid.
Conical flask glass jam jars measuring cylinder stop clock watch with seconds stop watch app direct reading balance dilute hydrochloric acid cotton wool marble chips method.
Acid rain is one of the top degradation agents for marble artefacts around the world.
Marble chips calcium carbonate caco 3 react with hydrochloric acid hcl to produce carbon dioxide gas.
A the collisions are more frequent and higher energy.
The chemical equation that is going to be followed throughout the experiment will be.
The experiment is repeated using smaller marble chips.
An investigation of the reaction between marble chips and hydrochloric acid.
An outline of an experiment that could be used to find the time and hence rate of reaction of marble chips and hydrochloric acid.
The marble chip is calcium carbonate caco3.
Caco3 2hno3 ca no3 2 co2 h2o this particular reaction is rather slow and so needs to be quicker by changing the factors that affect the rate of reaction.
