10 cubic inches
We will use Boyle's law that states that for a fixed amount of an ideal gas kept at a fixed temperature, pressure and volume are inversely proportional.
P1 V1 = P2 V2
Where
P1 is initial pressure = 5 psi
V1 is initial volume = 20 cubic inch
P2 is final pressure = 10 psi
V2 is final volume = unknown
V2 = P1,V1 / P2
V2 = 20 × 5 / 10
V2 = 100/10
V2 = 10 cubic inches
<em>Answer:</em>
The equlibrium concentration sof Ca+2 ion willl be 4.9×10∧-3 M
<em>Data Given:</em>
Ksp of CaSO4 = 2.4 × 10∧-5
CaSO4 ⇔ Ca+2 + SO4∧-2
<em>Solution:</em>
Ksp = [Ca+2].[ SO4∧-2]
2.4 × 10∧-5 = [x].[x]= x²
x = 4.9×10∧-3 M
<em>Result:</em>
- The conc. of Ca+2 ion is 4.9×10∧-3 M
Answer:
There would be around 2.7*10^24 molecules.
Explanation:
You have to multiply the amount of moles by Avogadro's number to get amount of molecules.
Answer:
Orbitals give a probability map of where it is likely to find an electron in an atom.
Explanation:
Wave mechanical model of the atom suggests that an atom contains a nucleus which has positively charged protons and neutral neutrons.
The outer part of the atom is mostly empty.
The negatively charged electrons are located in outer orbitals.
The true statement is :
Orbitals give a probability map of where it is likely to find an electron in an atom.
