Answer:
5.3 atm
Explanation:
We can solve this problem using the equation of state for an ideal gas, which states that:
where
p is the pressure of the gas
V is its volume
n is the number of moles
R is the gas constant
T is the absolute temperature of the gas
For a gas undergoing a transformation, n and R remain constant, so the equation can be written as
For the gas in this problem we have:
is the initial temperature of the gas
is the final temperature
is the initial pressure
, as the volume is decreased by 40.0%
Solving for , we find the final pressure of the gas:
Answer:
2. Na1 +
Explanation:
The formular for sodium fluoride is; NaF
The metal in sodium flouride is sodium.
Sodium belongs to group 1, hence would lose one electron when forming ions.
This is represented as;
Na+
Answer:
Explanation:
An isotope is a form of a chemical element whose atomic nucleus contains a specific number of neutron s, in addition to the number of proton s that uniquely defines the element. The nuclei of most atom s contain neutrons as well as protons
Answer:
gosh I think it's the earth of example of example a lot is reversible for you and climate science professor and bottom up is reversible in the context and bottom lines
Density = mass/volume = 80 g/10cm³ = 8 g/cm³
