Answer :
0.125 g
Explanation : If you are calculating the half life of P-32 which has half life of 14.3 days and you want to calculate how many grams are remaining after 71.3 days if yo are starting with 4 g?
starting you can calculate the number of half life P-32 undergoes first,
which is n = 71.5 / 14.3 = 5 days.
now, to calculate the remaining mass,
=
Answer:
copper
Explanation:
These are usually copper wires with no insulation. They make the path through which the electricity flows. One piece of the wire connects the current from the power source (cell) to the load
Answer:
Atom is a particle that defines a chemical element, and is normally surrounded by 2 electrons.
Also, how do you that font ?
This is not the best way to organize a periodic table because two elements might have similar atomic mass.
<h3>What is periodic table?</h3>
Periodic table is a chart in which arrangement of chemical elements are done.
In the early periodic table elements are arranged on the basis of their atomic masses, while after sometime Moseley arranged the periodic table on the basis of atomic number as he proposed that properties of an element is justified on the basis of number if electrons.
And mass of two substances may be same so it is difficult to differentiate between them.
Hence, two elements might have similar atomic mass.

Answer:
is the overall voltage produced
Explanation:
Potassium and Tin are connected in an electrochemical series.
In a series circuit, the resultant voltage is equal to the sum of voltage drops at all points in the circuit.
Here,
The voltage drop at potassium 
The voltage drop at Tin 
The net voltage
