Answer:
The correct answer is option B. From 200K to 400K
Explanation:
Hello!
Let's solve this!
The ideal gas equation is the following PV = nRT
Where the variables are:
P: pressure
T: temperature
V: volume
R: universal constant of ideal gases
n: number of moles
We see in the equation the proportional relationship of volume with temperature.
We deduce that if the volume increases twice, then the temperature increases twice.
The temperature has to be in Kelvin, that's why we chose that answer.
Of the options, the correct answer is option B. From 200K to 400K
Answer:
Types of bonding in chemistry
There are three primary types of bonding: ionic, covalent, and metallic. Definition: An ionic bond is formed when valence electrons are transferred from one atom to the other to complete the outer electron shell.

18 g of silicon-32 will be present in 800 years.
A radioactive half-life refers to the amount of time it takes for half of the original isotope to decay and it's given by
where,
quantity of the substance remaining
the initial quantity of the substance
time elapsed
the half-life of the substance
From the given information we know:
The initial quantity of silicon-32 is 40 g.
The time elapsed is 800 years.
The half-life of silicone-32 is 710 years.
So, using the calculation above, we can determine how much silicon-32 is left.
Therefore,18 g of silicon-32 will be present in 800 years.
