Consider the reaction:
goldfiish [28.3K]

Answer:

K = Ka/Kb

Explanation:

P(s) + (3/2) Cl₂(g) <-------> PCl₃(g) K = ?

P(s) + (5/2) Cl₂(g) <--------> PCl₅(g) Ka

PCl₃(g) + Cl₂(g) <---------> PCl₅(g) Kb

K = [PCl₃]/ ([P] [Cl₂]⁽³'²⁾)

Ka = [PCl₅]/ ([P] [Cl₂]⁽⁵'²⁾)

Kb = [PCl₅]/ ([PCl₃] [Cl₂])

Since [PCl₅] = [PCl₅]

From the Ka equation,

[PCl₅] = Ka ([P] [Cl₂]⁽⁵'²⁾)

From the Kb equation

[PCl₅] = Kb ([PCl₃] [Cl₂])

Equating them

Ka ([P] [Cl₂]⁽⁵'²⁾) = Kb ([PCl₃] [Cl₂])

(Ka/Kb) = ([PCl₃] [Cl₂]) / ([P] [Cl₂]⁽⁵'²⁾)

(Ka/Kb) = [PCl₃] / ([P] [Cl₂]⁽³'²⁾)

Comparing this with the equation for the overall equilibrium constant

K = Ka/Kb

Explain what would happen to the air temperature at Riverdale School over the course of the
monitta

Answer:

Air temperature increases.

Explanation:

The air temperature at Riverdale School increases if the groundwater system were used because this system uses very huge amount of water than the other system. By using more molecules having the same temperature, the thing with more molecules has more total kinetic energy or thermal energy than the thing with fewer molecules so that's why air temperature of the school is increases.

How many grams of o2(g) are needed to completely burn 70.2 g of C3H8(g)
Lubov Fominskaja [6]
First you must write a balanced chemical equation.

C3H8 + 5O2 --> 3CO2 + 4H2O

From there, we can set up the stoichiometry equation to solve.

g O2= 70.2 g C3H8 X (1 mol C3H8/44.0962g C3H8) X (5 mol O2/1 mol C3H8) X (31.998g O2/1 mol O2)

Now solve, and you should get 254.7 g O2. Hope this helped!

Write a c++ program that prints the intial letter of any name​
Masteriza [31]

Answer:

please mark as brainliest!!

Explanation:

// C++ program to print initials of a name  

#include <bits/stdc++.h>  

using namespace std;  

 

void printInitials(const string& name)  

{  

   if (name.length() == 0)  

       return;  

 

   // Since touuper() returns int, we do typecasting  

   cout << (char)toupper(name[0]);  

 

   // Traverse rest of the string and print the  

   // characters after spaces.  

   for (int i = 1; i < name.length() - 1; i++)  

       if (name[i] == ' ')  

           cout << " " << (char)toupper(name[i + 1]);  

}  

 

// Driver code  

int main()  

{  

   string name = "prabhat kumar singh";  

   printInitials(name);  

   return 0;  

}
