elements have equal number of protons and neutrons
the condensed format is when the closest noble gas with the closest electron configuration is given, this closest noble gas atomic number should be lesser than the atoms atomic number
atomic number of Kr is 36
1 electron in 5s subshell and 7 electrons in 4d subshell.
there's a total of 36 + 1 + 7 = 44 electrons
atomic number of the atom is 44
element with atomic number 44 is Ruthenium - Ru
answer is Ru
Answer:
In a chemical equilibrium, the forward and reverse reactions occur at equal rates, and the concentrations of products and reactants remain constant. A catalyst speeds up the rate of a chemical reaction, but has no effect upon the equilibrium position for that reaction.

Answer:
6.68 x 10^-4
Explanation:
131g ÷ 261.337g/mol = 0.5012685 moles
0.5012685 moles ÷ 750.0 liters =
0.5012685÷ 750.0=0.000668358
6.68 x 10^-4
Gay-Lussacs law states that pressure is directly proportional to temperature at constant volume.
in this case the volumes of the 2 containers remain the same therefore volume is constant.
P/ T = k
where P - pressure, T - temperature and k - constant
when temperature decreases the pressure too decreases and vice versa.
if temperature of one container is lowered the pressure also reduces.
since one containers temperature is lowered the pressure in that container reduces.
answer is when temperature is lowered, pressure too is lowered.
Answer:
Her Eid per Ruth Jααte Hαin wo Humse,
αb bαtαo Hum Eid Mαnαye yα unko.
ہر عید پر روٹھ جاتے ہیں وہ ہم سے
اب بتاؤ ہم عید منائے یا ان کو
ik ishq ka gam aafat aur us pe ye dil aafat
ya gam na diya hota ya dil na diya hota
bas ek jhijhak hai haal-e-dil sunaane mein,
ki tera bhi jikr aaega mere is phasaane mein.
kya kahoon kis tarah se jita hoon
gam ko khaata hoon aansoo pita hoon
