Answer:

Cd(NO₃)₂ + 2NH₄Cl → CdCl₂ + 2NH₄NO₃

Explanation:

The reaction given is a double replacement reaction, which means that the reactants will dissociate and the ions will be changed between them. So, let's identify the ions.

At Cd(NO₃)₂, the metal Cd has cation Cd⁺², and the anion is NO₃⁻ (the number of ions is changed and the cation is the first to appear in the formula). At NH₄Cl, the cation is NH₄⁺ and the anion is Cl⁻, so the products are CdCl₂ and NH₄NO₃ (the cation comes first, and the charges are replaced between them).

So, the reacion will be:

Cd(NO₃)₂ + NH₄Cl → CdCl₂ + NH₄NO₃

To balance the equation, all the elements must have the same number on both sides, thus we need to multiply NH₄Cl and NH₄NO₃ by 2:

Cd(NO₃)₂ + 2NH₄Cl → CdCl₂ + 2NH₄NO₃

How do particles in matter change when a substance becomes hotter, cool down, or changes state?
Nana76 [90]

Answer:

When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.

hope this helps!!!!!!

The final acceptor for hydrogen ions in aerobic cellular respiration is
Whitepunk [10]
The appropriate response is oxygen. Cellular respiration is the procedure cells use to make vitality. Cells in our body join glucose and oxygen to make ATP and carbon dioxide. Oxygen is utilized as an electron acceptor inside the electron transport tie of vigorous breath to create adenosine triphosphate or ATP. This compound is a fundamental part in intracellular vitality exchange.
