1 Science is certain about ending up with the actual explanation while pseudoscience does not ensure that.
2
Science is involved with a set of principles to work, while pseudoscience is not operated in a unique method.
3 Science is based on tangible or perceptible evidence, but pseudoscience could be based on some superficial or outlandish concepts.
4 Science result the truth while pseudoscience results the myth.
Respuesta:
16,7 mL
Explicación:
Paso 1: Información provista
- Concentración inicial (C₁): 6%
- Concentración final (C₂): 0,5%
- Volumen final (V₂): 200 mL
Paso 2: Calcular el volumen de la solución concentrada
Queremos preparar una solución diluida de hipoclorito de sodio a partir de una concentrada. Podemos calcular el volumen inicial que debemos tomar usando la regla de dilución.
C₁ × V₁ = C₂ × V₂
V₁ = C₂ × V₂ / C₁
V₁ = 0,5% × 200 mL / 6% = 16,7 mL

<h3><u>Answer;</u></h3>
El Nino
<h3><u>Explanation</u>;</h3>
- El Nino is a weather pattern that begins as a result in an increase in the water temperature at the surface of the Pacific ocean that produces a warm current.
- It is a climate pattern that describes the unusual warming of surface waters in the eastern tropical Pacific Ocean.
- It has an impact on ocean temperatures, the speed and strength of ocean currents together with the health of coastal fisheries. Its events occur irregularly at two- to seven-year intervals.
