Answer:
Final pressure of light bulb is 2.03 atm.
Explanation:
Given data:
Initial pressure = 1.34 atm
initial temperature = 26 °C
Finial temperature = 179 °C
Final pressure = ?
Formula:
P1/T1 = P2/T2
Solution:
First of all we will convert the °C into kelvin.
179 +273 = 452 K
26 +273 = 299 K
P2 = P1×T2/T1
P2 = 1.34 atm . 452 K / 299 K
P2 = 605.68 atm/ 299
P2 = 2.03 atm
this is lithium ion with a +1 charge
<span>The relationship between the amount of space between particles and the state of matter is that if the distance between the particles is very very less or closely packed) then it said to be a solid , If the distance between the particles is very less (more than that of solid) then the matter is a liquid & If the distance between the particles is less (more than that of liquid) then it is said to be gaseous. By this we conclude that when the amount of space between the particles varies then the states of matter (Solid , Liquid , Gas) also differs.</span>
Answer:
Rb<K<Ga<As<Se<S
Explanation:
We must remember that first ionization energy decreases down the group and increases across the period.
First ionization energy decreases down the group because of the addition of more shells which increases the distance between the nucleus and the outermost electron. Hence, Rb has a lower ionization energy that K.
Across the period, increase in the size of the nuclear charge causes the pull of the nucleus on the outermost electrons to increase thereby increasing the ionization energy. Hence ionization energy increases across the period. For this reason, the ionization energy of Ga<As<Se as shown.
It would be d.
Reason being said...
the electron configuration normally goes like this...
1s2 2s2 2p6 3s2 3p6 4s2....
until you hit the transition metals..remember those have a special rule..
even though you are in the 4 sublevels for the orbitals ... it goes down 1
Making it 3d..(1,2,3,4,5,6,7,8,9,10)
Going on...
at 5s2 then, 4d1, 4d2, 4d3, 4d4, etc..
at 6s2 then, 5d1, 6d2, 6d3, 6d4, etc..
Thus, D orbital is your answer.
