I A QUESTION WHAT IS

Mg+HCL->MgCL2 +H2

IS IT SYNTHESIS, SINGLE REPLACEMENT, DOUBLE REPLACEMENT OR DECOMPOSITION THX BYE

Single replacement. Mg replaced the H.

To determine the type of reaction that the chemical equation represents, we need to analyze the components of the equation.

In the given chemical equation:

Mg + HCl → MgCl2 + H2

We have magnesium (Mg) reacting with hydrochloric acid (HCl) to produce magnesium chloride (MgCl2) and hydrogen gas (H2).

Based on their positions in the periodic table, we know that magnesium (Mg) is more reactive than hydrogen (H). In a single replacement reaction, a more reactive element replaces a less reactive element in a compound. Here, magnesium displaces hydrogen in the hydrochloric acid, forming magnesium chloride and releasing hydrogen gas.

Therefore, the reaction: Mg + HCl → MgCl2 + H2 is a single replacement reaction.

Hope this helps. Let me know if you have any further questions!
