Answer:
When chlorine water is added to potassium bromide solution, chlorine will displace the bromine from the salt solution. The chlorine will be REDUCED (gain electrons) to chlorine ions. The bromide ions will be OXIDISED (lose electrons) to become bromine. The bromine will turn the solution orange.

Answer:
The density of air goes down as you get higher with altitude.
Explanation:
Less air is pushing down on the molecules below it as you go up. This means that it is not as compacted, another word for which is dense.
It must be made of matter because anything and everything is made up of atoms. The other three options are made of atoms but they are also matter.
The molarity of the ammonia solution is 1.38 M
<h3>Definition of molarity</h3>
Molarity is defined as the mole of solute per unit litre of the solution. Mathematically, it can be expressed as:
Molarity = mole / Volume
<h3>Determination of the mole of NH₃</h3>
•Mass of NH₃ = 23.5 g
•Molar mass of NH₃ = 14 + (3×1) = 17 g/mol
•Mole of NH₃ =?
Mole = mass / molar mass
Mole of NH₃ = 23.5 / 17
Mole of NH₃ = 1.38 mole
<h3>Determination of the molarity </h3>
•Mole of NH₃ = 1.38 mole
•Volume = 1 L
•Molarity of NH₃ =?
Molarity = mole / Volume
Molarity of NH₃ = 1.38 / 1
Molarity of NH₃ = 1.38 M

According to Bronsted-Lowry acid concept
an acid is a that donate a proton" and a base is a "proton acceptor."so
will look for that molecule to which <span><span>H2</span>O</span> "donates" <span>H+</span>to become <span>O<span>H−</span></span>. so answer will be..
. <span>N<span>H3</span>+<span>H2</span>O→N<span>H+4</span>+O<span>H<span>−
so correct option is NH3
hope it helps</span></span></span>
