Answer:

Platinum is a greyish-white metal of high lustre, and is very malleable and ductile. It melts in the oxy-hydrogen blowpipe and in the electric furnace; it is harder than gold and is a good conductor of electricity. In finely divided form it has the ability to absorb or occlude gases

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 : $Pd^{2+}(aq)+2e^-\rightarrow Pd(s)$

cyclopropane is a commonly used anesthetic. If a 2.00 L flask contains 3.11 g of cyclopropane gas at 684 mmHg pressure and 23.0

jeka94

Answer:

42.0g/mol

Explanation:

The steps for this question is to use the ideal gas law, and then use n=m/M to find molar mass.

PV = nRT

n= PV/RT

Change 23 degrees to 296.15 K and 684mmHg to kpa

n = (91.1925kpa)(2.00L)/(8.314Lkpa/mol K)(296.15K)

n= 0.074mol

n = m/M

M = m/n

M = 41.98489g/mol
