Q: Answer the following question given this paragraph: Some reactions need extra help to occur quickly. They need another substance called a catalyst. A catalyst is a substance that increases the rate of a chemical reaction. A catalyst isn't a reactant, so it isn't changed or used up in the reaction. Therefore, it can catalyze many other reactions. Q: Some reactions need extra help to occur quickly. they need another substance called what? A:
Answer: a catalyst

Problem:OPTIONS:
- electrodes cell
- symbiotic cell
- stimulation cell
- galvanic cell

Answer the following question given this paragraph: Thus the potential of a galvanic cell can be used to measure the pH of a solution. Exercise Suppose you work for an environmental laboratory and you want to use an electrochemical method to measure the concentration of Pb2+ in groundwater. You construct a galvanic cell using a standard oxygen electrode in one compartment (Ecathode = 1.23 V). The other compartment contains a strip of lead in a sample of groundwater to which you have added sufficient acetic acid, a weak organic acid, to ensure electrical conductivity. The cell diagram is as follows". Q: The potential of what can be used to measure the ph of a solution? A:
****
A: galvanic cell
