35 Celsius minus the average 20 Celsius. going to be 15. let me know if u need anything else.
Molar mass is the given substance divided by the amount of that substance, measured in g/mol.
Example: titanium atomic mass is 47.88 amu or 47.88 g/mol. In 47.88 grams of titanium there is 1 mole, or 6.022 x 10^23 titanium atoms.
Answer:
Moving them farther apart
Explanation:
One can try to change the distance between the two positive charges in such a way that it increases the distance and decreased the electric force.

¡Hola!
En este caso, dado que estamos tratando con problem sobre porcentaje peso/peso de hierro, arena, cobre y aluminio, primero debemos calcular la masa inicial de estos dos primeros en la mezcla original de acuerdo con:
Ahora si podemos calcular la masa de la mezcla final como la suma de las masas de todos los constituyentes de la mezcla:
Finalmente, podemos calcular los porcentajes P/P como se muestra a continuación:
¡Saludos!
