A decomposition reaction should look like
A ------> B +C+...
It has to have only one reactant and several products.
2 NO2 ⟶ 2 O2 + N2
Answer:
The weight-average molar mass of polystyrene is 134,160 g/mol.
Explanation:
Molar mass of the monomer styrene , 
, M=104 g/mol
Given , number average molar mass of the polymer , M'= 89,440 g/mol
Degree of polymerization = n
The weight-average molar mass = 
Molar mass dispersity is ratio of weight-average molar mass to the number average molar mass of the polymer.
The weight-average molar mass of polystyrene is 134,160 g/mol.
<span>Chemical equations are neither acidic nor basic, but you can evaluate the products of the reaction (and maybe the reactants too) and identify the existence of acids or bases which will indicate what kind of effects the reaction will have on the acidity. However, I'm not sure if you're asking the question you want to know the answer to, maybe you're wondering about balancing redox equations (which you do differently in acidic vs basic environments), in which case you'll need additional information beyond just an equation, but if the equation is redox and it's balanced just look for the presence of H+ ions or OH- ions on either side and that will tell you if it is acidic or basic (respectively), if neither is present, it'll be neutral.</span>
Answer:
This is a double displacement reaction, C goes with Cl in the products side and O2 goes with H. All that is left is to balance the equation, making sure each side has equal amounts of atoms.
