Answer:

Explanation:
Hello,
In this case, we apply the Gay-Lussac's law which allows us to understand the pressure-temperature behavior via a directly proportional relationship:

Thus, since we are asked to compute the final pressure we solve for it in the previous formula, considering the temperature in absolute Kelvin units:

Best regards.
Answer:
Different types of isotopes are used for different materials or objects. For radiometric dating, uranium-235 is considered best for it while carbon-14 is used for dating of rocks. It is also used for dating of wood samples.
Explanation:
Carbon-14 and uranium-235 are used for different materials or objects for measuring the age of these materials. These two isotopes are radioactive in nature which means they emit gamma radiations which allow us to find the age of different objects. Carbon-14 has a low half life so it can be used for those objects which are present before thousands of years while uranium-235 is used for materials which are millions of years old due to high half life.
Answer: The correct option is C.
Explanation: Beta minus (
) decay is the decay in which a neutron is converted into proton and releases beta particle or generally known as electron.
There is an increase in the Atomic number because one protons is being formed.
In the case of beta-minus decay of phosphorous, the P-nucleus gets changed to Sulfur nucleus. The balanced Chemical equation for this process is:

Hence, the correct option is C.
Answer:
All the options are correct except "has 7 electrons"
Explanation:
Answer:
Hydrocarbons
Explanation:
They all are made up of only carbon and hydrogen atoms, so they're organic molecules known as hydrocarbons. Decane and Heptane are alkanes, Propene is an alkene.
