Answer: If you change the number of electrons in an atom it will become an ion

Explanation: When you change the number of protons in an atom, you will change the atom from one element to a different element. Sometimes, when you add a proton to an element, the element will become radioactive. If you change the number of electrons in an atom, you will get an ion of the element.

Que diferencia hay entre drogas estimuladoras depresoras y perturbadoras del sistema nervioso
12345 [234]

Answer:

Las drogas estimulantes son un grupo de medicamentos que tienen un efecto estimulante mental y físico en humanos y animales, estimulando y dando energía al paciente.  Ejemplos de psicoestimulantes son cafeína, efedrina, anfetaminas y metilfenidato.  Estos se usan en pequeñas dosis para, entre otras cosas, mejorar la atención del paciente y la capacidad de planificación, permitiendo un mayor y mejor rendimiento de la persona durante sus actividades diarias.

A su vez, un depresor es una sustancia que paraliza las funciones del sistema nervioso central, siendo las pastillas para dormir y los sedantes los depresores mas comunes. La acción de los sedantes se basa en su capacidad para activar los mediadores del sistema nervioso central, especialmente el ácido gamma-aminobutírico, causando en el paciente una sensación que puede ir desde la tranquilidad y relajación hasta un estado de somnolencia o incluso la propia inducción al sueño.

Por último, las drogas perturbadoras del sistema nervioso incluyen LSD, cannabis o la cocaína. Algunos efectos típicos son cambios en la visión y el oído, alucinaciones, confusión de sentidos, fuertes experiencias de belleza, disolución del yo y un sentido de unidad, experiencias religiosas y confrontaciones con el subconsciente. Este tipo de drogas son en su gran mayoría ilegales, y no forman parte de tratamientos médicos autorizados.

How many moles of Na2SO4 can be made with 7.28 mol of H2SO4?
Slav-nsk [51]

Answer:

7.28 mol Na2SO4

Explanation:

Since it is already in moles, all we have to do is use a molar ratio

A molar ratio is the proportions of reactants and products using the balanced equation. When writing a mole ratio, the given information must cross out with the right thing.

7.28 mol H2SO4 * 1 mol Na2SO4/1 H2SO4 = 7.28 mol Na2SO4

*notice how the H2SO4 crosses out
