d, one atom of oxygen and two atoms of hydrogen
The answer is powder because if it was a small crystal it the molecules are tightly compact same with the small cube but there less compact, powder is loose and more spread out and easier to mix so it would react the fastest
Lithium is an element that has an electronic configuration of 2,1. So when forming bonds, it tries to release one of its electrons in the last shell to reach the octet state. Normally when atoms release electrons they get positive charge since the number of protons which bear positive charge, is higher than number of electrons which bear negative charge. So when reaching its octet state, lithium gains positive charge!
Hope this helps! Tbh am not good at explaining. If u have any doubts, ask me!
2 mol KClO₃ - 3 mol O₂
x mol KClO₃ - 9 mol O₂
x=9*2/3= 6 mol
It has 4 significant figures. If you see the Zero after the one decimal point you don’t count that and instead just started at 6
