A voltaic cell that uses the reaction PdCl2−4(aq)+Cd(s)→Pd(s)+4Cl−(aq)+Cd2+(aq) has a measured standard cell potential of +1.03
Ghella [55]

Answer : The balanced two-half reactions will be,

Oxidation half reaction : Cd(s)\rightarrow Cd^{2+}(aq)+2e^-

Reduction half reaction : Pd^{2+}(aq)+2e^-\rightarrow Pd(s)

Explanation :

Voltaic cell : It is defined as a device which is used for the conversion of the chemical energy produces in a redox reaction into the electrical energy. It is also known as the galvanic cell or electrochemical cell.

In the voltaic cell, the oxidation occurs at an anode which is a negative electrode and the reduction occurs at the cathode which is a positive electrode.

The given redox reaction is:

PdCl_4^{2-}(aq)+Cd(s)\rightarrow Pd(s)+4Cl^-(aq)+Cd^{2+}(aq)

The balanced two-half reactions will be,

Oxidation half reaction : Cd(s)\rightarrow Cd^{2+}(aq)+2e^-

Reduction half reaction : Pd^{2+}(aq)+2e^-\rightarrow Pd(s)

What is the mass of 0.5 moles of ammonia, NH3?
Mashcka [7]

Answer:

Mass = 8.5 g

Explanation:

Given data:

Mass of ammonia = ?

Number of moles = 0.5 mol

Solution:

Formula:

Mass = number of moles × molar mass

Molar mass of ammonia = 17 g/mol

By putting values,

Mass = 0.5 mol × 17 g/mol

Mass = 8.5 g

Mice21 [21]

Ecologists use food web diagrams as tools in their studies of different populations of organisms within an ecosystem because it shows the feeding relationship between organisms in the ecosystem.

<h3>What is a Food web?</h3>

This is defined as the graphical representation of the feeding relationship which occurs between organisms in the ecosystem and helps to predict the outcome in the addition or removal of a species.

The food web also helps to determine the various ways in which energy flows and it usually starts from the producers which are the plants as a result of their photosynthetic ability which involves the conversion of solar energy to chemical energy.

There are various organisms in the ecosystem and the food web helps to provide a better understanding of their feeding habits and impact various factors will result in.
