The brackets used to express concentration [ ], when making equilibrium constant calculations, indicate

1 answer:

4 0

Constant is K and that is the the concentration of product over the concentration of reactant for example for the equlibrium equation below
A+2B=3C
K= [C]^3/( [A]* [B]^2

A technician measures the weight of a reagent . The weight is 3269 g. What is the weight in kilograms ? Write your answer as a d

Georgia [21]

Answer:

3.269 kg

Explanation:

1000g = 1 kg. Since kg is the larger unit, you need to divide by 1000 to get kilograms. You can do the problem as a unit conversion:

3269 g × 1 kg = 3.269 kg

1000g

Which of the following is a galvanic cell?

sladkih [1.3K]

C. Aluminum (Al) oxidized, zinc (Zn) reduced

<h3>Further explanation</h3>

Given

Metals that undergo oxidation and reduction

Required

A galvanic cell

Solution

The condition for voltaic cells is that they can react spontaneously, indicated by a positive cell potential.

$\large {\boxed {\bold {E ^ ocell = E ^ ocatode -E ^ oanode}}}$

or:

E ° cell = E ° reduction-E ° oxidation

For the reaction to occur spontaneously (so that it E cell is positive), the E° anode must be less than the E°cathode

If we look at the voltaic series:

Li-K-Ba-Ca-Na-Mg-Al-Mn- (H2O) -Zn-Cr-Fe-Cd-Co-Ni-Sn-Pb- (H) -Cu-Hg-Ag-Pt-Au

The standard potential value(E°) from left to right in the voltaic series will be greater, so that the metal undergoing an oxidation reaction (acting as an anode) must be located to the left of the reduced metal (as a cathode)

From the available answer choices, oxidized Al (anode) and reduced Zn (cathode) are voltaic/galvanic cells.
