Answer:
Yes Calcium is more reactive than Lead.
Explanation:
Answer:
It is a law because it is a statement of fact that does not need any more experimental support.
Explanation:
A hypothesis is an acceptable assumption that is formulated through the collection of information and data and that attempts to explain some phenomenon. In other words, a hypothesis is a conjecture with which one tries to explain an observed fact. The formulation of a hypothesis can be derived in two different ways: by generalization, from a certain number of cases or observed phenomena; and, by analogies observed in the occurrence of different phenomena.
A theory is something that attempts to explain some phenomenon and that is accepted as true by the scientific community. In other words, a theory is a set of rules that describe the behavior of a particular system.
A law is a statement that expresses the constant relationships between phenomena of nature, society or the mind. Scientific law can be defined as an invariable relationship of terms. In other words, a law is what is scientifically proven to be true, it is universally applicable.
So scientific theories and scientific laws are based on hypotheses. But a theory is the explanation of an observed phenomenon, while a scientific law is the description of an observed phenomenon.
The movements of bodies in space are governed by Newton's Laws. These are laws why they are demonstrated by mathematical formulas and Universal application.
Then, the correct option is <u><em>"It is a law because it is a statement of fact that does not need any more experimental support."</em></u>
Answer: The Anode reaction is
Explanation:
Oxidation-reduction reaction or redox reaction is defined as the reaction in which oxidation and reduction reactions occur simultaneously.
Oxidation reaction is defined as the reaction in which a substance looses its electrons.Oxidation occurs at anode.
Anode :
Reduction reaction is defined as the reaction in which a substance gains electrons. Reduction occurs at cathode.
Cathode :
The land is warm during the day. For example, if you near a sea early in the morning, you could see how cold, cool the place is.
Answer:
0.6 atm
Explanation:
We have a state change at a constant temperature. For isothermal transformations, Boyle proposed the equation:
P1V1 = P2V2 (Boyle's Law)
Where P1 and V1 are the pressure and the volume in the first state and P2 and V2 the pressure and the volume at the final state. So:
4x3 = 20xP2
20xP2 = 12
P2 = 0.6 atm
