ANSWER:
all of them
Explanation:
preciseness is measured by how many decimal places are used not by accuracy. since all of these are to the same decimal place they are all equally precise even if they are inaccurate.
Answer:
The molecular weight 62,03 g/mol
Answer:
C. molecules
Explanation:
Since, the temperature, pressure and volume conditions are same, the molecules of ammonia gas must be equal to the molecules of the argon according to the ideal gas equation which is shown below as:-
where,
P is the pressure
V is the volume
n is the number of moles
T is the temperature
R is Gas constant having value = 0.0821 L.atm/K.mol
Thus, both will have same moles and same number of molecules.
<u>Thus, molecules of argon = molecules</u>
Answer:
The six changes are: Freezing: the substance changes from a liquid to a solid. Melting: the substance changes back from the solid to the liquid. Condensation: the substance changes from a gas to a liquid.
