What type of chemical reaction is represented by Mg(s) + 2HCI(aq) MgCl2(aq) + H2(g)

This reaction is a displacement reaction.

Explanation:

Both elements and compounds are chemical substances. However, there's only one type of atom in an element. In a compound, there are at least two different kinds of atoms.

For example,

In a displacement reaction, an element reacts with a compound to produce another element and a different compound. In this reaction,

Hence this reaction is a displacement reaction.

As a side note, this reaction matches the pattern:

.

In other words, if the here is replaced with a different metal that is sufficiently reactive (such as aluminum ,) the reaction should still be a displacement reaction.

given:

mass of na = 115 g

excess cl2

to determine:

mass of nacl produced

explanation:

given reaction is-

2na(s) + cl2(g) → 2nacl(s)

since cl2 is in excess, na will be the limiting reagent

as per the reaction stoichiometry na: nacl = 1: 1

i.e. moles of na reacted = moles of nacl formed

now, # moles of na = mass of na/atomic mass

                                  = 115 g/23 g.mol-1 = 5 moles

therefore, moles of nacl = 5

molar mass of nacl = 58 g/mol

mass of nacl = 5 moles * 58 g.mol-1 = 290 g

ans: amount of nacl produced = 290 g

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions

explanation:

hope this and sorry i could only come up with one answer!
