Well to solve this problem, we must remember that Oxygen
in ionic form is Oxide O2- (an electric charge of negative 2). Hence the
correct formulas and names taking into account the charge of Oxygen are:
c) Co2O3, cobalt(III) oxide
f) CoO, cobalt(II) oxide
<h2><u>Answer:</u></h2>
Component having Smallest Atomic Size is 'Helium' having range approx. 31pm
I have seen that numerous individuals are noting with respect to hydrogen Atom however the genuine reason is along a period (left to right) the nuclear number increments while the valence electrons stay in a similar shell. Along these lines because of the expanding atomic charge (pulling electrons closer to the core) the radii of the iotas decline left to right.
Furthermore, as should be obvious from the table, Hydrogen and Helium are in a similar period so Helium having littlest size
Answer: Option (b) is the correct answer.
Explanation:
When the cake is baked then due to the heat provided to it there will occur movement of its molecules.
As a result, molecules will gain kinetic energy due to which there will occur collisions between them.
Also, 
Hence, more is the heat provided to the cake more will be the kinetic energy of its molecules due to which when we touch it, it feels hot.
Thus, we can conclude that molecules in the cake are moving faster than molecules in the skin, best explains why the cake feels hot.
Answer: yes
Explanation: cuz i know lol
