What is effective collision?
The collision that produce new substance.
The collision that has energy.
The collision that influence the rate of reaction.
The collision that break down all the cubstances.
Rate of reaction can be measured by ... .
Measuring the bubble amount.
Measuring the product decreases.
Measuring the product increases.
Measuring the reactant increases.
Look at the picture. What method is used to measure the rate of reaction according to the picture?
Product's mass measuring.
Product volume measuring.
Reactant volume measuring.
Reactant's mass measuring.
Look at the chemical reaction below:
Mg+ Cu(NO3)2-->
Write the product.
MgCu(NO3)2
CuMg(NO3)2
Cu+ Mg(NO3)2
CuMg+ (NO3)2
Which single displacement can occur?
Al+ Li2SO4Al
Li+ Al2(SO4)3
LiAl+ (SO4)3
Al+ Li
A student add marble chip into hydrochloric acid to produce carbondioxide bubble. Which way cannot ben used to speed up the chemical reaction?
Adding more marble chip.
Using high concentration of hydrochloric acid.
Use marble powder.
Heat the chemical reaction.
A student plan to investigate the rate of reaction written below:
Na2S2O3(aq)+ 2HCl(aq)--> 2NaCl(aq)+ H2O(l)+SO2(s)+ S(s)
The student did the experiment at home. He doesn't have electrical balance and syringe. What method the student can use?
Look at the picture. Differentiate the situation of those 3 chemical reaction.
Those three chemical reactions are the chemical reaction using the different time.
Those three chemical reactions are done in 3 different reactant.
Those three chemical reactions are done in 3 different temperature in which the red graph is the highest, follow by blue graph and yellow is the lowest.
Those three chemical reactions are done in 3 different temperature in which the yellow graph is the highest temperature, follow by blue graph and red.
A student investigate the reactivity of some unknown metals: X, Y and Z. She used the same amount of those metals in the test tubes, then add the same amount of hydrochloric acid. Those metals reacted to produce gass. X stop react after 45 sec. Y stop react after 26 sec. Z stop react after 65 sec.
Arrange the reactivity of those 3 metals from the most reactive to the least reactive.
X, Y, Z
Z, Y, X
Y, X, Z
Z, X, Y
A student want to investigate the influence of concentration to the rate of reaction written below:
Fe + HCl --> FeCl+ H2
What to keep the same and different?
We've to keep the same amount of Fe and HCl but set the different time to do the experiment.
We've to set all the same, unless the amount of HCl.
We have to keep the amount of Fe and HCl the same but using different HCl concentration.
We've to use catalyst and more Fe. But we keep using the same item of chemical.
