We are provided with
4.35 g of phosphoric acid
5.25 g of KOH
3.15 g of K3PO4 produced
The reaction formula is
H3PO4 + 3KOH => K3PO4 + 3H2O
Initially, convert the given masses into moles.
Then, identify the limiting reactant. Afterward, calculate the maximum K3PO4 that can be generated from the limiting reactant.
Finally, compute the percent yield by dividing the actual yield by the theoretical yield.
4.42x10⁻¹⁹ J/molecule Explanation: In a double bond, both sigma and pi bonds exist, while a single bond comprises only a sigma bond. Given that breaking both bonds requires 614 kJ/mol, while breaking just the sigma bond needs 348 kJ/mol, the energy specific to breaking the pi bond is calculated as E = 614 - 348 = 266 kJ/mol. Since 1 kJ equates to 1000 J, this correlates to 266,000 J/mol. With Avogadro's number (1 mol = 6.02x10²³ molecules), we calculate E = 266,000 J/mol * (1 mol/6.02x10²³ molecules) yields E = 4.42x10⁻¹⁹ J/molecule.
Response:
The data is insufficient.
Clarification:
The scenario presented includes fifteen players on the team.
However, Diana and Kinsey only surveyed five players from the starting lineup regarding their preferred mascot.
With such a minimal subset of the entire team, they lack the necessary data to select a mascot for their basketball team.
Therefore, the data is deemed insufficient.
Answer;
Considering the types of bonds being created and severed in the transition state, the stability of this temporary structure is comparatively high.
Explanation;
- The reaction can be expressed as follows; NO(g)+F2(g)→NOF(g)+F(g)
- All chemical reactions, including exothermic ones, require activation energy to initiate. The activation energy is the least amount of energy needed for the reactants to come together, overcome opposing forces, and begin breaking bonds.
- When molecules encounter each other, their kinetic energy may be sufficient to stretch, bend, and eventually break bonds, resulting in chemical reactions.
