// Comments are used for explanatory purpose

// Program Starts here

#include<iostream>

using namespace std;

int main ()

{

// Declare Variables

int quarter, dimes, nickel, cent;

// Enter values for each

cout<<"Quarter: ";

/*

In the United States, these coins have the following values

Quarter = 25 cents

Done = 10 cents

Nickel = 5 cent

Total cent is calculated below

*/

cent = 25 * quarter + 10 * dimes + 5 * nickel;

// Print Total

Calculate (a) the number of moles of hydrogen required to react with 0.0969 moles of nitrogen, and (b) the number of moles of am
Bumek [7]

Answer:

The answer to your question is:

Explanation:

Data

moles H=?

moles of N = 0.0969

moles of NH₃=?

                            N₂ (g)  + 3 H₂ (g)  ⇒   2NH₃ (g)

Process

1.- Set a rule of three to calculate the moles of hydrogen

                         1 mol of nitrogen  -------------   3 moles of hydrogen

                         0.0969 moles of N ----------     x

                         x = (0.0969 x 3) / 1

                         x = 0.2907 moles of hydrogen          

2.- Set a rule of three to calculate the moles of ammonia

                        1 mol of nitrogen --------------  2 moles of ammonia

                        0.0969 mol of N --------------   x

                        x = (0.0969 x 2) / 1

                        x = 0.1938 moles of ammonia

At 311 K, this reaction has a K c value of 0.0111 . X ( g ) + 2 Y ( g ) − ⇀ ↽ − 2 Z ( g ) Calculate K p at 311 K. Note that the
Aleks [24]

Answer:

K_{p}=4.35\times 10^{-4}

Explanation:

We know, K_{p}=K_{c}(RT)^{\Delta n}

where, R = 0.0821 L.atm/(mol.K), T is temperature in kelvin and \Delta n is difference in sum of stoichiometric coefficient of products and reactants

Here \Delta n=(2)-(2+1)=-1 and T = 311 K

So, K_{p}=(0.0111)\times [(0.0821L.atm.mol^{-1}.K^{-1})\times 311K]^{-1}=4.35\times 10^{-4}

Hence value of equilibrium constant in terms of partial pressure (K_{p}) is 4.35\times 10^{-4}

Suppose a piece of silver jewelry contains 5.23×1022 atoms of silver (ag). part a how many dozens of silver atoms are in the pie
IgorC [24]
Answer:
number of dozens = 4.35834 * 10^21 dozens

Explanation:
A dozen contains 12 atoms. To know the number of dozens containing
5.23 * 10^22 atoms, all we have to do is cross multiplication as follows:
1 dozen ...........> 12 atoms
?? dozens ......> <span>5.23 * 10^22 
number of dozens = (</span><span>5.23 * 10^22 *1) / (12)
number of dozens = 4.35834 * 10^21 dozens

Hope this helps :)</span>
