Answer:
Explanation:
N = Final mass of atom = 125 g
= Initial mass of atom = 16000 g
t = Time taken = 163.24 days
= Half life
We have the relation
The half life of the atom is .
A. Testing a hypothesis
This leads to the other points
Answer:
Yes. The volume would be 1/4 of the initial volume.
Explanation:
At constant temperature, the pressure of a gas is inversely proportional to the volume of the gas. Hence;
P1V1 = P2V2
<em>where P1 is the initial pressure, V1 is the initial volume, P2 is the final pressure, and V2 is the final volume.</em>
If the pressure of a gas is quadrupled;
P2 = 4P1, the equation becomes
P1V1 = 4P1 x V2
Making V2 the subject:
V2 = P1V1/4P1
V2 = V1/4
<em>This means that the volume would change by being reduced to </em><em>1/4 </em><em>of the initial volume.</em>
Density can be determined as:
d = m /V
whereas, m is mass of compound
v is volume
d = 700 /840 = 0.83 g /mL
Thus density is 0.83 g /mL
That would be an ionic bond since it has electrons to spare, rather than a convalent bond where all the electrons are taken up thus it is not a good conductor
