Examine the reactants of the incomplete double displacement reaction.
Elza [17]
<h3>Answer:</h3>

The products of the reaction are; AgCl and  NaNO₃

<h3>Explanation:</h3>

In this question we need to know what is a double displacement reaction;

  • A double displacement is a type of replacement reaction in which salts or ionic compounds exchange cations and anions to form new compounds as the products.
  • In this case, the complete double replacement reaction is;

AgNO₃(aq) + NaCl(aq) → AgCl(s) + NaNO₃(aq)

  • The reaction is also a precipitation reaction as it forms a precipitate as one of the products that is silver chloride (AgCl).
  • Therefore, the products of the reaction are; AgCl and  NaNO₃

Propane burns in oxygen to produce carbon dioxide and water. How many grams of oxygen gas are required
Kruka [31]

Answer:

m_{O_2}=36.3gO_2

Explanation:

Hello!

In this case, since the reaction between propane and oxygen is:

C_3H_8+5O_2\rightarrow 3CO_2+4H_2O

Given the 1:5 mole ratio between propane and oxygen, and their molar masses (44.09 g/mol and 32.00 g/mol respectively), we can follow up the shown below stoichiometric setup to compute the required mass of oxygen for the reaction:

m_{O_2}=10.0gC_3H_8*\frac{1molC_3H_8}{44.09gC_3H_8}*\frac{5molO_2}{1molC_3H_8}  *\frac{32.00gO_2}{1molO_2} \\\\m_{O_2}=36.3gO_2

Best regards!
