In cells use oxygen to release energy stored in sugars such as glucose. In fact, most of the energy used by the cells in your body is provided by cellular respiration. Just as photosynthesis occurs in organelles called chloroplasts, cellular respiration takes place in organelles called mitochondria.

Consider the following reaction
Fynjy0 [20]

Answer:

92.72 kJ

Explanation:

2 N₂ (g) + O₂ (g) —-> 2 N₂O

According to question , one mole of N₂O requires 163.2 kJ of heat

Molecular weight of N₂O = 44 gm

25 g  N₂O = 25 / 44 mole

25 / 44 mole will require 163.2 x 25 / 44 kJ

= 92.72 kJ

In this experiment, we will be performing a titration with a buret. place the steps in order. 1. record the ph when 0.0 ml of na
77julia77 [94]

I am guessing that your solutions of HCl and of NaOH have approximately the same concentrations. Then the equivalence point will occur at pH 7 near 25 mL NaOH.

The steps are already in the correct order.

1. Record the pH when you have added 0 mL of NaOH to your beaker containing 25 mL of HCl and 25 mL of deionized water.

2. Record the pH of your partially neutralized HCl solution when you have added 5.00 mL of NaOH from the buret.

3. Record the pH of your partially neutralized HCl solution when you have added 10.00 mL, 15.00 mL and 20.00 mL of NaOH.

4. Record the NaOH of your partially neutralized HCl solution when you have added 21.00 mL, 22.00 mL, 23.00 mL and 24.00 mL of NaOH.

5. Add NaOH one drop at a time until you reach a pH of 7.00, then record the volume of NaOH added from the buret ( at about 25 mL).

6. Record the pH of your basic HCl-NaOH solution when you have added 26.00 mL, 27.00 mL, 28.00 mL, 29.00 mL and 30.00 mL of NaOH.

7. Record the pH of your basic HCl-NaOH solution when you have added 35.00 mL, 40.00 mL, 45.00 mL and 50.00 mL of NaOH from your 50mL buret.

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.
