Answer:
well she can test both of the soap by putting one on and plate and another on the other plate and which ever is cleaner is your answer
Acceleration is when something is being moved forward or back, motion is just movement, friction is two or more things rubbing together, so the answer should be B. gravity
Answer:
1. No 1 looks like a statement and not a question.
2.Ionic compounds are usually formed from the transfer of electrons from metals to Non metals. All others are Ionic compounds except HCl(Its a covalent compound).
3. The Formula would be K2S. Exchange of Radicals takes place. Sulphur has a -2 charge and potassium has a +1 charge. when they both exchange radicals... The compound is K2S.
4.Group 1 elements have only 1 electron in their outermost shell.
5. its charge will be +1 because it loses the 1 electron in its outermost shell.
6.Group 2 elements have 2electrons in their Valence shell.
7.Already answered. same as No 5.
8. Group 16;Also known as group 6. They have only 6 electrons in their outermost shell.
9.When they want to become stable... they acquire 2electrons to complete their octet... so they possess a -2 charge by forming an ion.
10. i)They form ions when Dissolve in solutions
ii) They are hard and brittle
iii) They have high boiling points
Answer:
Increasing substrate concentration also increases the rate of reaction to a certain point. Once all of the enzymes have bound, any substrate increase will have no effect on the rate of reaction, as the available enzymes will be saturated and working at their maximum rate.
Answer :
(a) The overall equation is:
(b) The intermediates are :
Explanation :
<u>Part (a) :</u>
(1) 
(fast)
(2) 
(slow)
(3) 
(fast)
By adding the three equations and cancelling the common terms on both side, we will get the overall equation.
<u>Part (b) :</u>
Intermediates are generated and consumed in the mechanism and do not include in the overall equation.
Since, intermediates will not include in the overall mechanism.
The intermediates are :
