No, Na2S(aq) + 2HCl(aq) ®2NaCl(aq) + H2S(g) is a double displacement reaction.
Yes, when sodium reacts with Hydrochloric acid it replaces the hydrogen as hydrogen gas. 2Na + 2HCl = 2NaCl + H2
H2SO4 + Zn --> ZnSO4 + H2 It's an exothermic single-replacement reaction.
Ba(OH)2 (aq) + 2HCl (aq) --> BaCl2 (aq) + 2H2O (l)
Single replacement reactions have the general form a+bx-->ax+b. Some examples: Fe(s)+2HCl(aq)-->FeCl(aq)+H2(g) Cu(s) + 2AgNO3(Aq) --> Cu(NO3)2(Aq) + 2Ag(s) 2Na(s) + 2H2O(l) --> 2NaOH(Aq) + H2(g)
Na2B4O7.10H2O (borax) + 2HCl ---> 2NaCl + 4H3BO3 + 5H2O
Yes, when sodium reacts with Hydrochloric acid it replaces the hydrogen as hydrogen gas. 2Na + 2HCl = 2NaCl + H2
2NaCl + H2SO4 = Na2SO4 + 2HCl
Correctly represented, it's Mg + 2HCl --> MgCl2 + H2, and it's a single replacement reaction.
Correctly represented, it's Mg + 2HCl --> MgCl2 + H2, and it's a single replacement reaction.
Ca + 2HCl --> CaCl2 + H2
It can be, but it can also be other types of reaction. An example of an oxidation reaction that is also a single replacement would be Zn(s) + 2HCl ==> ZnCl2 + H2. In this reaction Zn is oxidized and H is reduced.
Na2CO3 + 2HCl ----> 2NaCl + H2O + CO2
The reaction is: 2HCl + Na2CO3 = 2NaCl + CO2 + H2O
You bet it is. Na2CO3 + 2HCl ==> 2NaCl + H2O + CO2
Na2CO3 + 2HCl --> 2NaCl + CO2 + H2O
It is exothermic. Heat will be released to the environment in this reaction. It is also a single replacement reaction. Here is the equation: 2HCl + Mg --> MgCl2 + H2
Correctly represented, it's Mg + 2HCl --> MgCl2 + H2, and it's a single replacement reaction.
