Answer:
I have for Decompostion
Explanation:
A decomposition reaction occurs when one reactant breaks down into two or more products. It can be represented by the general equation: AB → A + B. In this equation, AB represents the reactant that begins the reaction, and A and B represent the products of the reaction

Answer: There are 4.8 x 1024 hydrogen atoms in 2.0 moles of CH4 
 
        
                    
             
        
        
        
The  grams  of aluminum  that are required   to produce  3.5  moles of AlO3  in  presence of excess O2   is calculated as  below
write  the  equation for reaction
4 Al + 3O2 =2 Al2O3
by use of mole  ratio between  Al  to  Al2O3   which  is  4 :2  the moles of  Al 
=3.5 x4/2 = 7  moles
mass of Al  =  moles /   x molar mass
= 7 moles  x27 g/mol  =189  grams
