What is the temperature (in K) of 16.45 moles of methane gas in a 4.95 L container at 4.68 atm?
AlexFokin [52]
Using the ideal gas law: PV=nRT
      P is pressure; V is volume; n is the amount in moles; R=0.082; T is temperature in K.

(4.68)*(4.95)=(16.45)*(0.0821)*T
Solve for T. 
T=17.15

Can periodic table indicates occurrance of the elements, why?​
Allushta [10]

Answer: No

Explanation:

A periodic table can be defined as the table in which the row of chemical elements are present. All the elements of the row have same number of electron shells.

The arrangement of elements is based on atomic numbers, electron shell model and other chemical properties. The elements are placed in increasing order of atomic number.

This table does not give information about the occurrence of the elements.

If equal amounts of silver ion are added to silver bromide and silver chloride, why does the bromide mixture precipitate first?
VARVARA [1.3K]
Answer is: precipitation requires fewer Ag⁺<span> ions in AgBr than in AgCl.
Chemical reactions:
Ksp(KBr) = 5,3</span>·10⁻¹³.
Ksp(KCl) = 1,8·10⁻¹⁰.
Ksp is <span>solubility product constant. The higher the Ksp value, substance is more soluble. KBr has lower Ksp, so it is easier to form precipitant of KBr than KCl.</span>
