Hello!
If the reaction could be made to go faster B. The hill would be shorter.
The "hill" is called Activation Energy. It is the energy of the activated intermediate compound needed to complete the reaction. Catalysts are substances that don't intervene in the reaction which speed up the rate of a given reaction by lowering the Activation Energy giving alternate reaction pathways with lower-energy intermediates. If the reaction could be made to go faster with the use of a catalyst, then the Activation Energy would be lower and the "hill" would be shorter.
Have a nice day!
Answer:
0.0970 M
Explanation:
Remember this equation:
mol/M x V
Convert it so that you can get M.
M=mol/V
Convert the 2.14 grams of H2SO4 into mols
=0.0218
Convert mL to L
225/1000
=0.225
Plug it in.
0.0218/0.225
=0.0970 M
23. The correct answer would be a (AlPO4 + H2O).
This is an example of a neutralization reaction (an acid and a base react to form water and a salt).
24. a, combination reaction. There are two reactants and one product.
Answer: D. When the independent variable is continuous and shows a causal link to the dependent variable.
Explanation: Line graphs are usually very useful in visualizing relationships between variables (dependent and independent variable). Line graphs produce a very simple plot of these variables, however, by mere visualizing a line graph, one can tell if there exist a causal relationship between the measured variables. The independent variable when creating line graphs are real numerical values which should be continuous, aligning with the trend line produced by the graoh.
