Identify the type of reaction: 2AgCl + BaBr2 -> 2AgBr + BaCl2

Chemistry
1 answer:
Marta_Voda [28]2 years ago
6 0

Answer:

C

Explanation:

Just look at the reactants.

2AgCl + BaBr2

The first reactant is made of 2 elements.

The second reactant is made of 2 elements.

It can't be a decomposition. At this level there is only one reactant made of 2 elements. Something like

2MgO ===> 2Mg + O2

is a decomposition.  One compound breaking down into 2 elements Mg and O.

It can't be a combustion. One of the reactants in a combustion is oxygen. Those equations look like

C3H8 + 5O2 ==> 3CO2 + 4H2O

That would be what a combustion looks like

It can't be a single replacement. They look like

Mg + CuO ===> Cu + MgO

There are elements on both sides of the reaction.

that leaves a double replacement which I wrote about how you distinguish it.

Aretes and horns are the landforms that are created where cirques meet. These landforms are products of glacier erosion in most temperate and polar regions.

  • Cirques are common products of alpine glacier erosion.
  • They arise in form of bowl shaped hollows on the side of a mountain.
  • These hollows joins to form a U-shaped valley called Aretes and unique pointed arcs known as horns.
