Answer 2

The given chemical equations are:

1. HCl + Mq = H2SO4 + Zn
2. HCl + Cu = ?
3. H3PO4 + Mq = ?

Let's examine each equation one by one:

1. HCl + Mq = H2SO4 + Zn: This equation represents a single replacement reaction where hydrogen chloride (HCl) reacts with an unknown metal (Mq), resulting in the formation of sulfuric acid (H2SO4) and zinc (Zn). Without knowing the specific identity of Mq, it is difficult to determine the products precisely. However, typically in single replacement reactions, the more reactive metal displaces the less reactive metal. Therefore, if Mq is more reactive than Zn, it will displace Zn and form its own compound with HCl. On the other hand, if Mq is less reactive than Zn, no reaction will occur.

2. HCl + Cu = ? This equation represents a potential reaction between hydrochloric acid (HCl) and copper (Cu). The balanced equation for this reaction would be:

2HCl + Cu → CuCl2 + H2

In this reaction, copper (Cu) displaces hydrogen from hydrochloric acid (HCl), resulting in the formation of copper(II) chloride (CuCl2) and hydrogen gas (H2).

3. H3PO4 + Mq = ? This equation represents a reaction between phosphoric acid (H3PO4) and an unknown metal (Mq). Similarly to the first equation, without the specific identity of Mq, it is challenging to determine the products accurately. The reaction outcome depends on the reactivity of Mq with respect to hydrogen and phosphorus. If Mq is more reactive than hydrogen, it may displace hydrogen and form its own compound with phosphoric acid. If Mq is less reactive than hydrogen, no reaction will occur.
