A voltaic cell spontaneously converts chemical energy to electrical energy. The correct option among all the options given in the question is option "2".
Actually voltaic cell is an electrochemical cell that
converts the chemical contained within it by the process of chemical reaction
to produce electrical energy. The voltaic cell contains an anode and a cathode.
Anode is an electrode where the oxidation occurs and cathode is the electrode
where reduction occurs. The oxidation and the reduction part occurs in two
separate parts of the cell known as half-cell.
GPS- Global Positioning System, this is be found in cars
Google Maps- Finding the nearest Starbux, the map is generated by satellite data.
Phone calls and text messages- the signals go from your phone to the satellite and back down to whoever you're texting.
Hope this helps :)
Answer:
a. 58.5 g/mol
b. 0.1 mol
Explanation:
a.
The molar mass of Na is 23.0 g/mol. The molar mass of Cl is 35.5 g/mol. The molar mass of NaCl is:
M(Na) + M(Cl) = 23.0 g/mol + 35.5 g/mol = 58.5 g/mol
b. A healthy adult should eat no more than 6 g of salt in one day. The moles corresponding to 6 g of NaCl are:
6 g × (1 mol/58.5 g) = 0.1 mol
Answer:
The identity does not matter because the variables of Boyle's law do not identify the gas.
Explanation:
The ideal gas law confirms that 22.4 L equals 1 mol.
