Explanation:
- Atomic number of krypton [Kr] =36
- Electronic configuration of krypton [Kr] = [Ar]
- Common ions with valence electronic configuration of [Kr] are bromine ion, strontium ion, selenite ion and rubidium ion.
- The Atomic number of the following ions in increasing order are;
Se < Br < Rb < Sr
Se (Z) = 34
Br (Z) = 35
Rb (Z) = 37
Sr (Z) = 38
- Electronic configuration of the following elements are:
Se (Z) = [Ar]
Br (Z) = [Ar]
Rb (Z) = [Kr]
Sr (Z) = [Kr]
Therefore, the respective ions formed according to theabove electronic configuration are 
Hence the two anions are
and, the two cations are

To answer this question, you need to understand the naming of meter unit system. The unit pm stands for pico meter which was 1/1000 of nanometer. Then, the calculation would be:
Number of atom= container length / atom diameter
Number of atom = 25 nm x (1000pm/nm) / 144pm= 173.6 atom
Answer:
heat flux ( Q ) = 8 W/m³ uniform heat flux throughout the block
Explanation:
flat plate ecuation with uniform source:
- d2T / dx² = - Q / k...........from general balance
- if x = 0 ⇒ dT / dx = 0 ; Q = 0
- if x = L ⇒ T = T1
∴ k = 0.04 W/mC; L = 0.2 m
If T = - 100x² + 20x
⇒ dT / dx = - 200x + 20
⇒ d2T / dx² = - 200 = - Q / k
⇒ Q / k = 200
⇒ Q = 200 * 0.04 W/mC
⇒ Q = 8 W/m³
Most substances in the food we eat need further digestion and must travel into the intestine before being absorbed. ... Chyme is then squirted down into the small intestine, where digestion of food continues so the body can absorb the nutrients into the bloodstream.
Hopes this helps:)
