The planet that orbits in a near circle is EARTH :D
The temperature that the balloon will expand to 3.50 l is 463.56 K
<em><u> calculation</u></em>
by use of Charles law formula
that is V1/T1 = V2/T2 where;
V1 = 2.25 l
T1= 298 k
V2= 3.50 l
T2=?
make T2 the subject of the formula T2 =(V2 xT1) /v1
T2= (3.50 l x 298 K) /2.25 L = 463.56 K
So, to determine the number of neutrons in atom, we only have to subtract the number of protons from the mass number. Take note that the nucleus of an atom is composed of protons and neutrons. And the number of particles present in the nucleus is referred as mass number (Also, called as atomic mass).
Answer:
El número de átomos de una molécula depende de la "valencia" de los elementos, ya que es la capacidad de la unión de los átomos.
Explanation:
La valencia de un elemento se define como la medida de la capacidad de combinación de un elemento. Es la capacidad de combinación de un elemento con otros elementos para formar un compuesto químico o molécula.
Básicamente es el número de electrones de valencia que un elemento puede perder, ganar o compartir para formar enlaces químicos requeridos a partir de compuestos o moléculas.

English Translation
The number of atoms of a molecule depends on the "valency" of the elements since it is the capacity of the union of atoms.
The valency of an element is defined as the measure of the combining ability of an element. It is the combining capacity of an element with other elements to form a chemical compound or molecule.
It is basically the number of valence electrons that an element can lose, gain or share in order to form chemical bonds required to from compounds or molecules.
Hope this Helps!!!
