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:
When two distinct elements are chemically combined—i.e., chemical bonds form between their atoms—the result is called a chemical compound. Most elements on Earth bond with other elements to form chemical compounds, such as sodium (Na) and Chloride (Cl), which combine to form table salt (NaCl).
Answer:
propane -1 2 3 - trioic acid
Answer:
Explanation:
The space between the large nucleus and the electrons is huge. We know this because the alpha particles shot at the gold foil most went right on through. That means that the space between hold atoms is very large.
B
Not only that but the deflection that takes place is not frequent further telling us that the the nucleus must be positively charged. That observation comes from the deflection itself. The charge on the nucleus must be the same as the alpha particle. If they were different, and the nucleus was negative, those particles that were deflected would now be absorbed.
The deforestation of tropical rainforest trees to create farms and pastures, and to harvest trees for construction has increased soil erosion.
<h3>WHAT IS DEFORESTATION:</h3>
- Deforestation is the process whereby trees are cut down for commercial purposes e.g. lumbering for paper production.
- Rainforest is a vegetation characterized by trees and shrubs. However, these trees serve as soil cover and help prevent soil erosion.
This means that deforestation of tropical rainforest trees to create farms and pastures, and to harvest trees for construction has increased soil erosion
