A glass jar sitting on a shelf.
If the shelf gets tipped the jar will slide off and convert to kinetic energy as gravity pulls it to land on the next level/floor
Answer:
Stoichiometric Values in a Chemical Reaction
Explanation:
The coefficients next to the reactants and products are the stoichiometric values. They represent the number of moles of each compound that needs to react so that the reaction can go to completion.
A neutral atom contains the same number of electrons as protons and that means that the electric charge of the atom is neutral or otherwise known as zero. However, if a particular atom loses an electron, the atom becomes positively charged because there is more protons than electrons.
THIS IS CALLED A CATION.
hope this helps x
First, let's find the number of neutrons in Calcium-40. to find the number of neutrons, you need to take the atomic mass minus atomic number
neutrons in Calcium---> 40 - 20 (atomic number) = 20 neutrons
potassium-40---> 40- 19= 21
scandium-44----> 44- 21= 23
argon-38---------> 38- 18= 20
chlorine-36------> 36- 17= 19
the answer is argon-38
