Duhhhhhhhdefinitely there will be some mole questions.

Why should more research be enforced in the biopolymer field?rofl mate
Because biopolymers suck tbh.no one answered
hahaha they're interesting.Because biopolymers suck tbh.
Amphiprotic or basic substances such as NaHCO3 and NaOH as this will neutralise the acid. (EG equation for HCl and NaOH neutralisation) Refer to conjugate acid and base to explain the idea of neutralising it into an end product that is neutral.hahaha they're interesting.
There has been an acid spill. Which substance do you use to combat this problem and why?
With these questions, i was advised to only talk about amphiprotic substances such as sodium hydrogen carbonate. Using NaOH could cause more problems, what if there is excess NaOH, then you have another problem that arises.Amphiprotic or basic substances such as NaHCO3 and NaOH as this will neutralise the acid.

Whoops. Thanks band 6.With these questions, i was advised to only talk about amphiprotic substances such as sodium hydrogen carbonate. Using NaOH could cause more problems, what if there is excess NaOH, then you have another problem that arises.
Sodium hydrogen carbonate can be used in excess.
hahahWhoops. Thanks band 6.
hahahahHahaha fixing an acid spill with a base spill
Thanks state rankers. I wouldve got zero if it popped uphahah
hahahah
hence why sodium hydrogen carbonate better choice.
plus in their marking criteria, they're probably looking for amphiprotic substance.
also balancing equationsDuhhhhhhh
noobalso balancing equations
QZP is the state ranker.Thanks state rankers. I wouldve got zero if it popped up
Can I join in on this game?What is the role of the salt bridge in a galvanic cell?
- Technetium-99m is used in medicine for medical diagnosis and tracing.Radioisotopes are used in industry, medicine and chemical analysis. For ONE of these fields, relate the use of a named radioisotope to its properties.
Yes the more people the better!Can I join in on this game?
- As oxidation occurs at the anode, electrons are lost by the electrode and cations go into solution. This results in a build-up of positive charge in the oxidation half-cell. Similarly, as reduction occurs at the cathode, cations in solution gain electrons and deposit on the cathode. This results in a build up of negative charge in the reduction half-cell.
- As the positive charge builds up in the oxidation half cell, the anion from the salt bridge (eg. NO3-) migrates towards it and neutralises the charge. Similarly, as negative charge builds up in the reduction half cell, the cation from the salt bride (eg. K+) migrates towards it to neutralise the charge.
- Thus, a salt bridge is able to keep the galvanic cell electrically neutral increasing efficiency of the cell.
- A salt bridge also facilitates the migration of ions between half-cells, thus completing the circuit.
Awesome! Describe the processes involved in the industrial production of ethanol from sugar cane.Yes the more people the better!
Ask questions after you answer one
Cellulose is extracted from the sugar cane. Suspension cellulose containing materials are heated moderately with concentrated sulfuric acid (4M) to break down the cellulose into glucose. The insoluble matter, particularly lignin from wood pulp is then filtered off. Impurities that are attached to the glucose are fractionally distilled and removed, and the acid is neutralized to produce a pure solution of glucose. Ethanol is then produced via fermentation. Fermentation is the process by which glucose is broken down by yeast, in the absence of air (anaerobic respiration) and at 35 degrees celsius to produce ethanol and carbon dioxide.Awesome!
