<h2>Greetings!</h2>

When balancing an equation, you need to know how many of each atom is on each side.

Left hand side:

1 Al , 1H , 1 Cl

Right hand side:

1 Al , 3 Cl, 2 H

You need to change the numbers on each side until the same amount is on both sides:

Al + HCl → AlC₃ + H₂

Al + 3HCl → AlC₃ + H₂

Al + 3HCl → AlC₃ + 3H₂

Al + 3HCl → AlC₃ + 3H₂

Al + 6HCl → AlC₃ + 3H₂

Al + 6HCl → 2AlC₃ + 3H₂

2Al + 6HCl → 2AlC₃ + 3H₂

Which is now balanced!

The balanced equation again is:

<h3>2Al + 6HCl → 2AlC₃ + 3H₂</h3>
<h2>Hope this helps!</h2>

The following balanced equation shows the decomposition of ammonia (NH3) into nitrogen (N2) and hydrogen (H2). 2NH3 → N2 + 3H2 A
Triss [41]
The decomposition of ammonia is characterized by the following decomposition equation:
                                  2NH₃<span>   →   N</span>₂  <span> +   3H</span>₂   

The mole ratio of N₂  :  H₂  is  1  :  3

    If the number of moles of N₂  =  0.0351 mol
    Then the number of moles of H₂  =  0.0351 mol  × 3
                                                         = 0.1053 mol

The number of moles of hydrogen gas produced when 0.0351 mol of Nitrogen gas is produced after the decomposition of Ammonia is  0.105 mol (OPTION 3).

A sample of glucose contains 1.250x10^21 carbon atoms, how many atoms of hydrogen does it contain?
dybincka [34]

Answer:

Hydrogen = 2.5 * 10^21

Explanation:

Chemical Formula Glucose: C₆H₁₂O₆

One of the ways you could do  this is to notice that for every carbon atom there are two Hydrogen atoms. You can state this more formally by using the formula to set up a ratio: 12/6 = hydrogen to Carbon

So if there are 1.250 * 10^21 Carbon atoms in the Glucose sample, then there will be twice as many hydrogen atoms.

H = 2 * 1.25 * 10^21 = 2.5 * 10^21 atoms

You could do this more formally by setting up a proportion.

6 Carbon / 12 Hydrogen = 1.25*10^21 /  x         Cross Multiply

6*x = 12 * 1.25*10^21                                           Combine the right

6x = 1.5 * 10^22                                                  Divide by 6

x = 2.5 * 10^21
