Attraction between a cation in one element and an anion in the other element
Answer:
67,9 L
Explanation:
Boyle's Law indicates that the pressure of a fixed amount of gas at a constant temperature is inversely proportional to the volume of a gas, for a constant amount of gas we can write:
P1V1=P2V2
For the problem:
P1= 1 atm, V1= 12,9 L
P2=0,19 atm, V2=?
Therefore:
V2=P1V1/P2.................... V2=1 atm*12,9L/0,19 atm = 67,9 L
The balloon would occupy a volume of 67,9 L in the upper atmosphere.
Quantum numbers describe values of conserved quantities in the dynamics of a quantum system. In the case of electrons, the quantum numbers can be defined as "the sets of numerical values which give acceptable solutions to the Schrödinger wave equation for the hydrogen atom
Answer:
Atoms, and chemical make up
Explanation:
Our bodies and any other terrestrial body are formed with atoms, those same atoms from a chemical make-up that creates items, such as water with 2 hydrogen atoms and 1 oxygen atom is formed. In essence, we all are about atoms and chemical makeup is the instruction on how to build us
