A voltaic cell with an aqueous electrolyte is based on the reaction between Cd2+(aq) and Mg(s), producing Cd(s) and Mg2+(aq). Wr

Monica [59]

Answer : The balanced two-half reactions will be,

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

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

Thus the overall reaction will be,

$Mg(s)+Cd^{2+}(aq)\rightarrow Mg^{2+}(aq)+Cd(s)$

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.

The given redox reaction occurs between the magnesium and cadmium.

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 balanced two-half reactions will be,

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

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

Thus the overall reaction will be,

$Mg(s)+Cd^{2+}(aq)\rightarrow Mg^{2+}(aq)+Cd(s)$

An airplane undergoes the following displacements, all at the same altitude: First, it flies 59.0 km in a direction 30.0° east o

ddd [48]

Answer:

B) 71.5 [km]

Explanation:

To solve this problem we will decompose each of the directions in the x & y axes.

To solve this problem we will decompose each of the directions in the x & y axes. also for a greater understanding of the angles, you should look at the attached image, which contains the orientations for each angle (clockwise or counterclockwise).

<u>59.0 km in a direction 30.0° east of north</u>

<u />

$d_{1x}= 59*sin(30) = 29.5[km]\\d_{1y}= 59*cos(30) = 51.09[km]$

<u>58.0 km due south</u>

<u />

$d_{2y} = - 58 [km]\\$

<u>It flies 100 km 30.0° north of west</u>

<u />

<u /> $d_{3x}= - 100*cos(30) = -86.6[km]\\d_{3y} = 100*sin(30)= 50 [km]$ <u />

<u />

Now we sum algebraically the components

$d_{x}=29.5-86.6 = -57.1[km]\\d_{y}=51.09 -58+50=43.09[km]\\\\$

Using the Pythagorean theorem we can find the magnitude of the displacement.

$d = \sqrt{(57.1)^{2} +(43.09)^{2} } \\d= 71.53[km]$

What two factors affect the gravitational force between two objects

Marina86 [1]

Answer:

When dealing with the force of gravity between two objects, there are only two things that are important – mass, and distance. The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them.Explanation:
