Of Course D) Increase the amount of Polonium.
You want "Increase" the Radioactivity, And since Polonium is himself radioactive, you need to increase its amount.
Hope this Helps :)
Answer:
Translation: Air resistance is a force that is caused by air. The force acts in the opposite direction to an object moving through the air.
Data are characteristics or information, usually numerical, that are collected through observation. In a more technical sense, data are a set of values of qualitative or quantitative variables about one or more persons or objects, while a datum (singular of data) is a single value of a single variable.
a physical phenomenon produced by the motion of electric charge, which results in attractive and repulsive forces between objects.
Answer:
The volume of the ballon is 325L.
Explanation:
Boyle's law express that the pressure of a gas is inversely proportional to its volume. That means if the pressure increases, the volume decreases. The formula is:
P₁V₁ = P₂V₂
<em>Where P represents pressure and V volume of 1, initial state and 2, final state of the gas.</em>
In the problem, the volume of the tank is 13.0L and the final pressure of the ballon is 1atm -The atmospheric pressure-. As 1atm of gas is in the ballon, the pressure of the tank is 26.0atm - 1.0atm = 25.0atm.
Replacing in Boyle's law expression:
25.0atm*13.0L = 1atmV₂
325L = V₂
<em>The volume of the ballon is 325L.</em>

Ammonia gas can be prepared by the following reaction:
In an experiment, 27.6 g of ammonia gas, , is produced when it was predicted that 50.2 g of would form.
What is the theoretical yield of ? What is the actual yeild of ? What is the percent yeild of ?
Answer: a) 50.2 g
b) 27.6 g
c) 5.0 %
Explanation:
a) Theoretical yield is defined as the amount of the product that is possible in the reaction.
Theoretical yield of = 50.2 g
b) Experimental or actual yield is defined as the amount of the product that is actually formed in the reaction.
Experimental yield of = 27.6 g
c) Percentage yield is defined as the ratio of experimental yileld to the theoretical yield in terms of percentage.
Hence percentage yield for the reaction is 55.0 %.
Answer: pH of buffer solution is 8.1
Explanation:
The formula for the Henderson–Hasselbalch equation is:
is the concentration of
is the acid dissociation constant,
and are concentrations of the conjugate base and starting acid.
Putting in the values we get:
Thus pH of buffer solution is 8.1
