Just divide 675 by the atomic number of cesium and you will end up with
5.078798426627975
Yes indeed yes indeed yes indeed
Answer:
ITS THE LAST ONE AND THE SECOND ONE
Explanation:
Explanation:
(a) the sublimation of dry ice [conversion of CO2(s) directly to CO2(g)]
The balanced equation is given as;
CO2(s) --> CO2(g)
This reaction is endothermic, hence; Heat is a reactant and is needed to start the reaction.
(b) the reaction of 1 mol of sulfur dioxide with oxygen.
The balanced equation is given as;
2SO2 + O2 --> 2SO3
This reaction is exothermic, hence; Heat is a product and is given off by the reaction.
