(2) a base because they accept H+ ions. NH3 is the conjugate base of NH4+.
Explanation:
Filtration is a separation technique in which solid particles suspended in liquid medium are separated by allowing the mixture through the pores of the filter paper. By this solid particles get collect on filter paper and liquid drains out from the pores of the filter paper.
The chronological order for given steps will be:
- Weigh and fold the filter paper.
- Place the filter paper in the funnel, then place the funnel in the Erlenmeyer flask.
- Allow the solid/liquid mixture to drain through the filter.
- Use water to rinse the filter paper containing the mixture.
- Weigh the dried filter paper and copper.
Answer:
The creation of regulations that limit timber activities and the exploitation of wood can prevent soil erosion in Troy.
Explanation:
The exploitation of the wood was an intense activity and that did not have any regulation that would limit its damages, caused by its exploratory activities.
As the timber market was totally undisciplined, the exploitation of the wood caused a strong deforestation, leaving the soil totally unprotected and susceptible to strong erosion.
Soil erosion has a very negative impact on the environment, requiring regulations to be made to prevent this from happening.
Based on this, we can say that one way to prevent environmental problems in the seaport of troy is by establishing laws and regulations that limit logging activities.
The chief advantage of the metric system over other systems of measurement is that it B. is in multiples of 10.
This can be seen in the picture below that shows the prefixes of the metric system.
