A student builds a rocket-propelled cart for a science project. Its acceleration is not quite high enough to win a prize, so he
irina [24]

Answer:

Explanation:

a = F / m

where a is acceleration , F is thrust and m is mass

taking log and differentiating

da / a = dF / F - dm / m

(da / a)x 100 = (dF / F)x100 - (dm / m) x100

percentage increase in a = percentage increase in F - percentage increase in m

= percentage increase in acceleration a   = 39 - 13 = 26 %

required increase = 26 %.

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)
