The correct option is A.
An oxidation reaction is one in which a substance gives away electrons and becomes oxidized. In the equation given above, the chlorate ion undergoes oxidation reaction and gives away two chlorine ion.
Answer:
Explanation: The lowest pressure in a laboratory is 4.0×10^-11Pa
Using Ideal gas equation
PV = nRT
P= 4.0×10^-11Pa
V= 0.020m^3
T= 20+273= 293k
n=number of moles = m/A
Where m is the number of molecules and A is the Avogradro's number=6.02×10²³/mol
R=8.314J/(mol × K)
PV= m/A(RT)
4.0×10^-11 ×0.020 = m/6.02×10²³(8.314×293)
m = 4.0×10^-11×0.020×6.02×10^23 / (8.314×293)
m = 1.98×10^8 molecules
Therefore,the number of molecules is 1.98×10^8
Answer:
-Determination - in this stage, people have make commitment to change the bad habit as soon as possible. it is stage of planning.
Explanation:
There are six stages of change that have a unique role in changing one's behavior. The stages are:
-Pre-contemplation - in this stage people are more aware of this bad habit but at the same time they are not considering as a problem
- contemplation - At this stage, people are more serious about their bad habit and now are thinking of changing
-Determination - in this stage, people have made a commitment to change the bad habit as soon as possible. it is stage of planning.
- Action - at this stage of change people are taking a serious step toward changing their behavior
- Maintenance - in this stage people are avoiding all those criteria and source through which there is a chance to return back to bad habits
-Relapse - at this stage people do resumption of old behavior
