4. Las bolsas de aire de los automóviles usan azida de sodio (NaN3) para producir nitrógeno molecular, el cual infla la bolsa de aire. Cuando un automóvil se impacta el sensor manda una señal eléctrica iniciando la descomposición del compuesto y la producción de oxígeno. ¿Cuántos gramos de azida de sodio se requiere para llenar una bolsa de aire si su volumen es de 60 litros? NAN3 Δ→ N2(g) + 2Na(s)

The human activities in two locations are described below: location a: rampant use of plastic containers location b: excessive use of pesticides and fertilizers which statement is most likely true? location a will have poor air quality because plastic is biodegradable. location a will experience water scarcity because plastic absorbs moisture. the population of honeybees will increase in location b because production of crops will increase. the population of fish in location b will decrease because the water is contaminated.

Determine the ph of 0.10 m nh3 solution. nh3 is a weak base with a kb equal to 1.8 x 10-5 round answer to nearest whole number.

What is the reduction potential of a hydrogen electrode that is still at standard pressure, but has ph = 5.65 , relative to the she?
