Rosa was looking for patterns to predict the products of chemical reactions. she recorded three similar decomposition reactions in the table.
a 2-column table with 3 rows. the first column labeled reactants has entries 2 n a c l o subscript 3, 2 k c l o subscript 3, 2 l i c l o subscript 3. the second column labeled products has entries 2 n a c l + 3 o subscript 2, 3 o subscript 2 + 2 k c l, empty.
what products should she record in the last row of the table?
The products should she record in the last row of the table : 2LiCl + 3O₂Further explanation
There are several chemical reactions, namely:Formation reaction Decomposition reaction. Replacement reaction. Multiple replacement reactions Neutralization reaction. Combustion reaction. Polymerization
The decomposition reaction in a chemical reaction shows the decomposition reaction of a compound into its constituent elements or compounds
Rosa recorded three similar decomposition reactions
Reactions that occur :
1. 2 NaClO₃ ⇒ 2NaCl + 3O₂
2. 2KClO₃ ⇒ 2KCl + 3O₂
3. 2LiClO₃ ⇒ 2LiCl + 3O₂
There are similarities in the decomposition that forms oxygen and chloride compounds
homogenous mixture of two or more pure substances
Keywords : products, patterns, chemical reaction, table, decomposition reactions
2LiCl + 3O₂
Hopefully this helps
A decomposition reaction is a chemical reaction in which one product is decomposed to form two or more products. In chemistry, decomposition is primarily achieved by heating the substance at high temperature.
Chlorates normally are decomposed when they are reached at a significant high temperature and are normally used for oxidation purposes. In the given examples from the table:
Sodium chlorate is decomposed to Sodium chloride and oxygen. Potassium chlorate follow the same principle and so will Lithium.
So, the reaction becomes:
2LiClO₃ > 2LiCl + 3O₂
You can see that both Sodium chlorate (NaClO3) and Potassium chlorate (KClO3) gave exactly the same products. i.e. a chloride and oxygen.
2LiCl + 3O2
is the answer
u yes and then she do what ppl do and cm
Hi! I need to talk to u asap
the answer is choice 1
your answer is A. 2LiCl + 3O2
rosa was looking for patterns to predict the products of chemical reactions. she recorded three similar decomposition reactions in the table.she should record 2licl + 3o2.
in the last row of the table. it is the thermal decomposition of chlorate lithium, hence, she should record these products as: lithium chloride ( 2licl ) and oxygen ( 3o2 ) 2 > 2 licl + 3o2.
