Answer:

The reaction is a double displacement reaction

Explanation:

Let us consider the reaction equation of the reaction between ammonium oxalate and lithium acetate.

(NH4)2C2O4(aq) +2 CH3COOLi(aq) -------> 2NH4CH3CO2(aq) + Li2C2O4(s)

This is a displacement reaction. A double displacement reaction is a type of reaction in which two reactants exchange their ions to form two new compounds. Double displacement reactions usually lead to the formation of a solid product which is also called a precipitate.

The general form of a Double displacement reaction is of the format:

AB + CD → AD + CB

Where A,B,C and D represents different ions respectively.

A double displacement reaction can also be referred to as salt metathesis reaction, double replacement reaction, exchange reaction, or a double decomposition reaction, although the latter term is more strictly used when one or more of the reactants does not dissolve in the solvent.

Answer:

148.2 g of H20

Explanation:

Equation of reaction: 4NH3 + 5O2 ---> 4NO + 6H20

From the equation above, 4 moles of ammonia reacts with 5 moles of oxygen gas to produce 6 moles water.

Molar mass of NH3 = 17 g/mol;

Molar mass of O2= 32 g/mol;

Molar mass of H2O = 18 g/mol

First, we determine the limiting reactant:

4*17 g of NH3 reacts with 5*32 g of O2

Mass Ratio = 68 : 160

Therefore, NH3 is the limiting reactant.

68 g of NH3 reacts to produce 6* 18 g of H20 = 108 g of H2O

93.3 g of NH3 will react to produce (93.3 * 108)/68 g of H20 = 148.2 g of H2O

Therefore, the maximum amount of H2O produced = 148.2 g

Answer: c. The rate of the forward reaction will increase.

Explanation:

Any change in the equilibrium is studied on the basis of Le-Chatelier's principle.

This principle states that if there is any change in the variables of the reaction, the equilibrium will shift in the direction to minimize the effect.

For the given equation:

$2NH_3(g)\rightleftharpoons N_2(g)+3H_2(g)$ $\Delta H=+ve$

This is a type of Endothermic reaction because heat is absorbed in the reaction.

When the temperature is increased, according to the Le-Chatlier's principle, the equilibrium will shift in the direction where decrease in temperature occurs. As, this is an endothermic reaction, forward reaction will decrease the temperature. Hence, the equilibrium will shift in the right or forward direction.
