increasing temperature

alexgriva [62]4 years ago
5 0
<h2>Answer with Explanation </h2>

An action of enhancing the temperature would be most feasible to improve the rate of reaction as the kinetic energy increments which generates the particles to collide with each other quicker. The rate of reaction duplicates for every 10 degree Celsius rise in temperature which causes the particles to have more collisions vigorously at an intense rate. The frequency of collisions also increases giving more speed to the rate of reaction which reaches energies equal to or greater than activation energy.

Why is a homogeneous mixture not considered a pure substance?
stepladder [879]
The answer is "A. a pure substance can be separated by chemical means, while a mixture can be separated by physical means". A pure substance only has one type of substance, whereas a mixture has more than one. A pure substance therefore, can only be separated chemically, because it is not two things mixed together, whereas a mixture can be separated physically because there are multiple substances.

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)

Why do certain substances dissolve in water and others don't? *
ipn [44]
<h2>Answer: <u><em>Hope this helps</em></u></h2>

Explanation:

<h3><u><em>Why do some substances dissolve in water and others don't? It has to do with the structure of the water molecule. Oxygen has a greater attraction for electrons, so the shared electrons (bonding electrons) spend more time close to oxygen then to either of the hydrogens.</em></u></h3>
