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.
28.01 g/mol is the answer for carbon monoxide (CO)
Answer:
The number and the kinds of atoms in the compound
Explanation:
- A chemical formula of a compound contains symbols o the atoms of the elements present in the compound as well as the number of atoms of each element in the form of subscripts.
- Therefore it helps us to know the elements in a compound and the number of atoms in the compounds.
So that every measurement is accurate.. hope this helps
