Why is it important for people to understand how to properly dispose of waste in a watershed?
Natali [406]

Answer:

disposing waste properly is important because watersheds are the surface water features and stormwater runoff within a watershed which ultimately end up in other bodies of water. It is essential to consider these downstream impacts when developing and implementing water quality protection and restoration actions. Everything upstream ends up downstream

Explanation:

A watershed describes an area of land that contains a common set of streams and rivers that all drain into a single larger body of water, such as a larger river, a lake or an ocean. For example, the Nile River watershed is an enormous watershed

Why do atomic model has changed over time
Elenna [48]

The model of the atom has dramatically changed over many many years.We learned atoms make up different substances and are the smallest particles of matter, which have subatomic particles that are very small portions of matter. At first scientist only thought there were electrons which are negatively charged.

According to the law of multiple proportions, if 12 g of carbon combine with 16 g of oxygen to form co, the number of grams of c
scZoUnD [109]

The amount of carbon combined with oxygen in order to form Carbon Dioxide(CO₂)  is 12 grams

The Law of Multiple proportions is one of the basic laws in chemistry along with the Law of Definite proportion. This law was proposed by John Dalton in 1803. The law states that if two elements react to form one or more compounds then the ratio of masses of both the elements is in the ratio of small whole numbers.

It is known that Carbon can form two different compounds while reacting with Oxygen that is: Carbon Monoxide, Carbon Dioxide. For Carbon Monoxide, 12g of Carbon needs to react with 16g of Oxygen. Whereas, In Carbon Dioxide, 12g of Carbon needs to react with 32g of Oxygen. So the mass of Carbon is equal in both cases is 12g.

                      C(12g)   +   O(16g)   ⇒  CO   (Carbon Monoxide)    

                      C(12g)   +  2O(32g) ⇒  CO₂  (Carbon Dioxide)
