Hello!
Ok so for this problem we use the ideal gas law of PV=nRT and I take it that the scientist needs to store 0.400 moles of gas and not miles.
So if we have
n=0.400mol
V=0.200L
T= 23degC= 273k+23c=296k
R=ideal gas constant= 0.0821 L*atm/mol*k
So now we rearrange equation for pressure(P)
P=nRT/V
P=((0.400mol)*(0.0821 L*atm/mol*k)*(296k))/(0.200L) = 48.6 atm of pressure
Hope this helps you understand the concept and how to solve yourself in the future!! Any questions, please feel free to ask!! Thank you kindly!!!
Answer:
A chemical change is a change in the chemical makeup of a substance and results in a new substance. Ice and water both have the same chemical makeup - ice is just a different state and has the same atoms but in an expanded form.
Explanation:
the nucleus represented by x is 56
Answer:
magnesium (Mg)
Explanation:
Both are in group 2 and because of that share the same chemical properties.
<u>Answer:</u>
NO ---> N +2 and O -2
<u>Explanation:</u>
Oxidation numbers are assigned to the elements of a compound to keep a track of the number of electrons each atom has.
Here we have a compound NO (Nitrogen Oxide). The Nitrogen is assigned an oxidation number of +2 while Oxygen in this compound is assigned an oxidation number of -2.
So the algebraic sum of the oxidation numbers of the elements in the compound NO is equal to zero.
