Answer:
The correct answer is c. adding a catalyst for the reaction
Explanation:
The function of a catalyst in a chemical reactionis to increase the rate of reaction by decreasing the required activation energy which is clearly illustrated on energy diagrams. It is not consumed in the reaction and can be reused repeatedly,as such, only small quantities of catalysts are required in the reaction. Catalyst provide a separate route for a chemical reaction to proceed at a lower activation energy than an uncatalysed reaction
The process of speeding up a chemicals reaction by the addition of a catalyst is known as catalysis
Pass the mixture through a screen to allow the salt and pepper to pass through but traps the pebbles. Mix the salt and pepper with water to dissolve the salt and filter it to get the pepper.
Answer: hope this helps
To make molar NaCl solutions of other concentrations dilute the mass of salt to 1000ml of solution as follows:
0.1M NaCl solution requires 0.1 x 58.44 g of NaCl = 5.844g.
0.5M NaCl solution requires 0.5 x 58.44 g of NaCl = 29.22g.
2M NaCl solution requires 2.0 x 58.44 g of NaCl = 116.88g.
Explanation:
I would say the answer is P2O5. Some teachers use PO2.5. I'm not one of them.
