Answer:
The pressure inside the chamber is 0.132 atm
Explanation:
Step 1: Data given
The initial volume = 0.027 L
The initial pressure = 1.0 atm
The volume changes to 0.205 L
Step 2: Calculate the pressure
P1*V1 = P2*V2
⇒with P1 = the initial pressure = 1.0 atm
⇒with V1 = the initial volume = 0.027 L
⇒with P2 = the changed pressure = TO BE DETERMINED
⇒with V2 = the changed volume = 0.205 L
1.0 atm *0.027 L = P2*0.205 L
P2 = 0.027/0.205
P2 = 0.132 atm
The pressure inside the chamber is 0.132 atm
Calculate its molar solubility in a saturated aqueous solution that is also 0.050 M in fluoride ion, F-. Ksp = (x)(2x + 0.05)2. 2x = 4.210 4
The element group which is least likely to form ions is 4A group
<u><em>explanation</em></u>
Element of group 4A has 4 valence electrons. for example Carbon which has [He] 2S2 2P2 electron configuration has 4 valence electrons.
Since 4A elements has 4 valence electrons , it means that their valence shell is half filled which is relatively stable. <em>For this reason 4A element readily form ions.</em>
Answer:
Period
Explanation:
The name of the rows in the periodic table being period.
A column would be called a group/family.
