Light of certain energy shines on a metal and causes
electrons to be emitted. Based on the
research of Albert Einstein, the change that would most likely result in
stopping the emission of electrons from this metal is to coat the metal.
Answer:
A
Explanation:
A formal charge (FC) is the charge assigned to an atom in a molecule, assuming that electrons in all chemical bonds are shared equally between atoms, regardless of relative electronegativity(Wikipedia).
The formal charge on an atom in a molecule reflects the electron count associated with the atom compared to the isolated neutral atom(University of Calgary).
Looking at all the structures listed A-E for SeO2F2, only structure A minimizes the formal charges for each atom in SeO2F2.
=>. the function of greenhouse gases are
=>. it captures the heat comming out from the
sun
=>. by capturing the heat it makes our earth
warm
=> if excess of heat will traped by them then
our earth become more warm and this leads
to increase in temperature
=> when the overall temperature will increase
then the ice sheets on pole will melts
and this leads to increase in sea level
=> then the land near water will sinks in water
<span>Nuclear reactions have two main types: fission reactions and fusion reactions. When two light nuclei are joined to create a heavier and more stable nucleus, this process is called the fusion reaction. In the fission reaction, the heavy nucleus split into two nuclei with a smaller mass number. In other words, fission is splitting of atoms although not all atoms undergo fission, only few went through normal circumstances (that is a fact). </span>
