1. Which of the following is a combination reaction?
DaniilM [7]

Answer:

The answer to your question is: letter A

Explanation:

A combination reaction is when there are two reactants that gives only one product.

a. 2SO2 + O2—> 2SO3                          This is a combination reaction,

                                                               2 reactants gives one product.

b. Zn + Cu(NO3)2–>Zn(NO3)2 + Cu     This is not a combination reaction,

                                                                it's a single replacement reaction.

c. 2H2O2–> 2H2O+O2                          This is a decomposition reaction

d. AgNO3 + NaCl → AgCl+NaNO3        THis is a double replacement reaction.

If we have 1.23 mol of NaOH in solution and 0.85 mol of Cl2 gas is available to react, which one is the limiting reactant? Give
Vinil7 [7]

Answer:

NaOH is the limiting reactant.

Explanation:

Hello there!

In this case, since the reaction taking place between sodium hydroxide and chlorine has is:

NaOH+Cl_2\rightarrow NaCl+NaClO+H_2O

Which must be balanced according to the law of conservation of mass:

2NaOH+Cl_2\rightarrow NaCl+NaClO+H_2O

Whereas there is a 2:1 mole ratio of NaOH to Cl2, which means that the moles of the former that are consumed by 0.85 moles of the latter are:

n_{NaOH}=0.85molCl_2*\frac{2molNaOH}{1molCl_2}\\\\n_{ NaOH}=1.7molNaOH

Therefore, since we just have 1.23 moles out of 1.70 moles of NaOH, we infer this is the limiting reactant.

Regards!
