Answer:
See image attached
Explanation:
The hydroxide ion concentration can easily be calculated from the concentration of the metal hydroxide solutions given as shown in the solution attached. The pH can now be obtained from there using pH+pOH=14. The pH value is always greater than the the pOH value as shown in the solution to the problems attached.
Question (c) contains incorrect data that cannot be used to calculate the required parameters.
Answer:
the difference is the presence of a carbon atom
Explanation:
Answer: normal fault
A fault refers to a planar or curved fracture in the rocks of the Earth crust, in which compressional or tensional forces results in the displacement of the rock on the opposite side of the fracture. Fault may vary in the length of the fracture. A normal fault is a fault in which the hanging wall of the rock moves downward to the footwall. It occurs when the two blocks of rock are separated apart by the tensional forces.
On the basis of the above information, the normal fault is the fault that should be found by the geologists in the rock.
Answer:
D
Explanation: When you chill a substance when it is mixed with another substance, ( chilled vinegar mixed with sodium bicarbonate will react slower for instance) it reacts slower do to the molecules slowing down when chilled.
