C. Mix household cleaners to get a stronger product.

This is not safe because mixing chemicals may cause a toxic gas to form. This gas is toxic to people and can cause health issues.

I'm really sorry it took so long the school Wifi cut off while i was writing it lol

The goal of this lesson:
mote1985 [20]

Answer:

1. The concentration of N₂O₄ decrease as the temperature of the system increased.

2. The formation of products was favored by the addition of heat.

3. The reaction going from right to left is exothermic.

4. N₂O₄ → 2NO₂; HR = +14 kcal.

Explanation:

Equation of the reaction is as follows: N₂O₄ ⇄ 2NO₂

The forward reaction proceeds with an increase in temperature. As the temperature of the reaction was increased, more of the N₂O₄ decomposed to form NO₂. Therefore, the concentration of N₂O₄ deceased.

2. The formation of products, that is the forward reaction leading to formation of NO₂ was favored by the addition of heat. Thus, with increase in temperature, the concentration of NO₂ increased.

3. An endothermic reaction is a type of reaction which requires energy input in the form of heat in order to proceed.

From the observations during the reaction, an increase in temperature by the addition of heat resulted in an increase in the forward reaction, therefore, the forward reaction is endothermic and the backward reaction is exothermic. Thus, the reaction in which colorless N₂O₄ is produced, is an exothermic reaction.

4. The change in enthalpy of a reaction is the difference in the heat content of reactants and products. For exothermic reactions, enthalpy change is negative, whereas for endothermic reactions, enthalpy change is positive.

The decomposition of  N₂O₄ to NO₂ is an endothermic reaction. Hence, the correct chemical equation is: N₂O₄ → 2NO₂; HR = +14 kcal.

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.
