I believe the answer would be Na+ BaO because Na is not above Ba on the activity series of metals. Hope this helps

Answer: The reactant pair Na + BaO will not react to produce a reaction.

Explanation: To study, if the reaction occurs or not, we should know about the reactivity series of the metals.

The metal which lies above in the reactivity series will easily displace the metals which lie below in the reactivity series.

The reactions which is based on the reactivity series are known as displacement reactions.

The reactants given in the question undergo single displacement reaction.

Single displacement reactions are defined as the reactions in which a more reactive element displaces the least reactive metal in a given chemical reaction.

$A+BX\rightarrow B+AX$

were, A is more reactive than B.

From the given reactant pairs, only one will not undergo a chemical reaction.

$Na+BaO\rightarrow \text{No reaction}$

$K+ZnBr_2\rightarrow 2KBr+Zn$

$2Al+6HCl\rightarrow 2AlCl_3+H_2$

$Mg+H_2O\rightarrow MgO+H_2$

The reactant pair (Na + Ba) will not undergo a reaction.

<u>Answer:</u> The rate law for the reaction is $\text{Rate}=k[NO_3][CO]$

<u>Explanation:</u>

Rate law is defined as the expression which expresses the rate of the reaction in terms of molar concentration of the reactants with each term raised to the power their stoichiometric coefficient of that reactant in the balanced chemical equation.

In a mechanism of the reaction, the slow step in the mechanism determines the rate of the reaction.

For the given chemical reaction:

$NO_2(g)+CO(g)\rightarrow NO(g)+CO_2(g)$

The intermediate reaction of the mechanism follows:

Step 1: $2NO_2(g)\rightleftharpoons NO_3(g)+NO(g);\text{ (fast)}$

Step 2: $NO_3(g)+CO(g)\rightarrow NO_2(g)+CO_2(g);\text{(slow)}$

As, step 2 is the slow step. It is the rate determining step

Rate law for the reaction follows:

$\text{Rate}=k[NO_3][CO]$

Hence, the rate law for the reaction is written above.

Lithium oxide + hydrochloric acid please

Morgarella [4.7K]

Answer:

Does lithium oxide react with hydrochloric acid?

Explanation:

Lithium Hydroxide reacts with acids to produce a Lithium salt: Hydrochloric Acid + Lithium Hydroxide → Lithium Chloride + Water. HCl + LiOH → LiCl + H2O. ... H2SO4 + 2LiOH → Li2SO4 + 2H2O

What are the spectator ions in this equation?

dangina [55]

The given question is incomplete. The complete question is :

What is the net ionic equation for the following reaction?

$H_2CrO_4+Ba(OH)_2$

Answer : The spectator ions are $Ba^{2+}$ and $CrO_4^{2-}$

Explanation:

Neutralization is a chemical reaction in which an acid and a base reacts to form salt and water.

Spectator ions are defined as the ions which does not get involved in a chemical equation or they are ions which are found on both the sides of the chemical reaction present in ionic form.

The given chemical equation is:

$2H^+(aq)+CrO_4^{2-}(aq)+Ba^{2+}(aq)+2OH^-(aq)\rightarrow Ba^{2+}(aq)++CrO_4^{2-}(aq)+H_2O(l)$

The ions which are present on both the sides of the equation are barium and chromate ions. and hence are not involved in net ionic equation.

Hence, the net ionic equation is $H^++OH^-\rightarrow H_2O$
