What is the complete balanced equation for the reaction that occurs when lithium carbonate (Li2CO3) is heated?

1 answer:

7 0

When heating lithium carbonate (Li2CO3), it will dissociate to Li2O and Co2. So the balanced chemical equation of this reaction is Li2CO3 = Li2O + CO2.

Consider the following mechanism: (1) ClO−(aq) + H2O(l) HClO(aq) + OH−(aq) [fast] (2) I−(aq) + HClO(aq) HIO(aq) + Cl−(aq) [slow]

TiliK225 [7]

Explanation:

$ClO^-(aq)+H_2O(l) \rightarrow HClO (aq)+OH^-(aq)\ [fast]$

$I^-(aq)+HClO(aq) \rightarrow HIO(aq)+Cl^-(aq)\ [slow]$

$OH^-(aq)+HIO(aq) \rightarrow H_2O(l)+IO^-(aq)\ [fast]$

(a)

Cancelling common terms, the overall reaction is as follows:

$ClO^-(aq)+I^-(aq) \rightarrow Cl^- (aq)+IO^-(aq)$

(b)

Chemical species which are generated and consumed during the reaction are called intermediates. Therefore, in the given reaction, HClO(aq), OH-(aq) and HIO(aq) are intermediate species.

(c)

two reactant molecules are involved in each steps, therefore, each steps are bimolecular. Since water is in excess, therefore will not be rate law

Rate law for first step:

$rate=k_1[ClO^-]$

Rate law for second step:

$rate=k_2 [I^-][HClO]$

Rate law for third step:

$rate=k_3[OH^-][HIO]$

(d)

Step 2 is slow step, therefore this step will be rate determining step.

So, rate = k [I-] [HClO]

So, it consisted with the actual rate law

Most grasshoppers stridulate to make sounds, what does that mean?

igomit [66]

Answer: grasshoppers produce sounds to attract mates or protect territory.

Explanation: Like their cricket cousins, grasshoppers produce sounds to attract mates or protect territory. Grasshoppers can be identified by their unique songs, which differ slightly from species to species. Grasshoppers stridulate by rubbing their wings together in the same manner as crickets.
