The correct answer is approximately 1.95g. First, take (1.022*10^10)/(1.277*10^9). This is the same as time elapsed/half-life. This gives you 8, which is the number of half lives. Then multiply mass (500.3g) by (1/2)^8, resulting in 1.95g, which is the answer.
Answer:
The see explanation
Explanation:
In this case, we have an <u>"amine"</u> group in the dopamine structure. So, the dopamine will act as a <u>"base"</u>. A base is a substance that has the ability to <u>accept hydrogens</u>, therefore, the 
will take hydrogen from the water molecule. Additionally, the water will produce the 
ion and the will be converted into 
.

Answer:
Similarly, if magnet is held stationary and the coil is moved away and towards the magnet, the galvanometer shows deflection in similar manner. It is also seen that, the faster the change in the magnetic field, the greater will be the induced emf or voltage in the coil.

The molecular formula tell us what elements the atoms are, and how many moles and atoms are attributed toward each element.
The molecular model tells us how the atoms/elements are bonded together.
