Mechanical energy = potential energy + kinetic energy
The ball is on the ground so has no potential energy.
M.E = K.E
M.E = 1/2 mv²
M.E = 1/2 x 1 x 2²
M.E = 2 J
Answer:
Calcium
2.8.8.2
last energy she'll got 2 electrons
as 2 valency
Answer:
The thermodynamic parameter which is of significance in this case is the 'Reduction Potential' for molecular bromine which is ~ +1.1 v vs N.H.E. In other words, it is a strong oxidizing agent. The bromine will oxidize sulfur compounds in which the valence of sulfur is lower than six to sulfate.
There are many possible reactions. Here is one possible example:
Na2 S2O3 + 4Br2 + 5 H2O = 2NaHSO4 + 8 HBr
A nuclear hypothesis is a model created to clarify the properties and practices of iotas. Similarly as with any logical hypothesis, a nuclear hypothesis depends on logical proof accessible at In compound responses, molecules join with each other in simple, charged particles (like electrons) that movement through space emit vitality.
Answer:
it has 79 protons
Explanation:
the atomic number is equal to the number of protons an element has.
