How is electroplating done
the metal on which electroplating is to be done is taken as
cathode ( negative electrode) . the metal of which electroplating
is to be done is taken as anode ( positive electrode) and the salt
solution of the metal of which electroplating is to be done is
taken as electrolyte .
example-
if we want to electroplate iron with copper then iron is taken
as cathode and copper is taken as anode and electrolyte is copper
sulphate.Electroplating is the process of plating one metal onto
another by hydrolysis, most commonly for decorative purposes. This
is done through the use of copper in a copper sulfate bath.
What is the problem if the car wont fire but still get power
If u mean still gets power as in compression and sprays fuel?
then your problem is your spark plug check if your spark plug is
working simply by unscrew it put the spark plug housing on and lay
it on the head of the engine of the car. (make sure that the metal
part on the side of the spark plug is touching the head of the
engine) if you have no spark then get a new one or fix it if u know
how..
What are the effects of a spark plug not working
A spark plug is used to ignite the fuel/air mixture inside the
cylinder of an internal combustion engine. If the spark plug isn't
working, the cylinder won't fire. In a multi-cylinder engine, this
will result in rough running and loss of power. In a small, single
cylinder engine, this will result in the inability to start the
engine.
What does a complete ionic equation look like
All ionic substances are written as separate ions in
solution
What is the correct sequence of steps in the four stroke engine cycle
air and fuel intake, compression and ignition, combustion and
expansion, exhaust
What makes balancing redox reactions different from balancing other reactions
Balancing redox reactions is different from balancing other
reactions because both the number of atoms and the amount of charge
must be balanced.
What pieces of information is given in a half reaction
The number of electrons transferred in the reaction . . APEX
c;
What is the number of molecules of 140g of co
What would be the percent yield of the reaction be if the theoretical yield is 11.22 g but the actual yield was 8.67 g
In this case the yield is 77,27 %.
What does not benefit of using biofuel instead of fossil fuels
Fossil fuel may be used in the production of biofuels.
Which the following is a necessary product of a combustion reaction
Air and fuel intake compression and ignition combustion and expansion and exhaust are sequential steps in
The four-stroke engine cycle.
In which step of the four-stroke engine cycle does the car release CO2 H2O and CO
Generating energy through combustion of renewable biofuels that cause minimal harm to the environment is an example of
The chemical reaction that occurs when gasoline and air are ignited is called an
Combustion reaction
(Apex)
In the reaction mgcl2 plus 2koh mgoh2 mgoh2 plus 2kcl if 3 moles mgcl2 are added to 4 moles koh what determined how much mgoh2 is made
What is the challenges poses the biggest problem to the long term use of alternative fuels
Electric engines may ultimately rely on fossil fuels for power.
Is not a concern regarding the use of corn as a biofuel
The color of corn is different than the color of gasoline or coal
APEX
How would 0.000000728 be written in scientific notation
It is 7.28*10^-7 in scientific notation
Which is the most likely to be reduced
something about "native" should be ur answer..apex
In the reaction 2Li(s)+2H2O(l) ➝ 2LiOH(aq)+H2(g), which compound is in the gaseous state
How is the mass of 1 mole of an element determined
It is the same as the element’s atomic mass, but in grams.
