Which equation represents a redox reaction?

labwork [276]

Answer:

D. $2NaBr + Cl_2\rightarrow 2NaCl + Br_2$

Explanation:

Hello!

In this case, for the given set of chemical reactions, it is possible to infer that D. is a categorized as redox due to the following:

Since both chlorine and bromine remain as diatomic gases, their oxidation states in such a form is 0, but as anions with lithium cations they have a charge of - according to the following reaction and half-reactions:

$2NaBr + Cl_2\rightarrow 2NaCl + Br_2$

$Cl_2^0+2e^-\rightarrow 2Cl ^-\\\\2Br^- \rightarrow Br_2^0+2e^-$

Unlike the other reactions whereas no change in the oxidation states is evidenced.

What is the concentration, in mass percent (m/m), of a solution prepared from 50.0 g nacl and 150.0 g of water?

Nataly [62]

Mass of solute ( m1 ) = 50.0 g

mass of solvent ( m2 ) = 150.0 g

Therefore:

m/m = ( m1 / m1 + m2 )

m/m = ( 50.0 / 50.0 + 150.0 )

m/m = ( 50.0 / 200 )

m/m = 0.25
