Answer:

1.3142 mol CoCl2

Explanation:

Well, to answer this we need to find out how many grams are in a single mole of CoCl2. Two find that we need to get the molar mass of CoCl2

Co = 28.0101 g Co per mole

Cl = 35.453 * g Cl per mole

28.0101 + 2 * 35.453 = 98.9161 g CoCl2 per mole

Now, we divide:

130/98.9161 = 1.3142 mol CoCl2

There are 1.31 moles in 130grams of cobalt chloride (CoCl2). Details about how to convert mass to moles can be found below.

The number of moles of a substance can be calculated by dividing the mass of the substance by its molar mass.

According to this question, there are 130g of CoCl2.

molar mass of CoCl2 = 28 + 35.5(2) = 99g/mol

moles = 130g ÷ 99g/mol

moles = 1.31 moles

Therefore, there are 1.31 moles in 130grams of cobalt chloride (CoCl2).

Answer:

Humans are modifying the world in many ways, and not all of them for the better. The changes we cause are often severe challenges to animals, plants and microbes in nature, from the introduction of pathogens or exotic invasive species to adding toxic substance or excessive nutrients, or causing climatic change. Often several changes occur at once. Nelson Hairston's lab focuses on freshwater environments, especially lakes and ponds, where some of the species present respond to environmental change with decreases in their numbers, even to the point of extinction, while others may benefit to excess, becoming so dominant that they present problems, as in the case of harmful algal blooms stimulated by nutrient enrichment or climate warming. Hairston's lab studies how individual species, food webs, and whole ecosystems are altered when the environment changes.

One way that some freshwater organisms respond to environmental change is to evolve rapidly. A marked change in the environment favors some characteristics of plants, animals and microbes over others. These character differences are often genetically based so that favored characteristics may increase in the next generation. The shorter the generation time, the faster this evolutionary change can occur. For example, tiny but abundant plankton, eaten by fish and other larger animals, can become adapted to the changed environment within a few years because their generation time is only a few days. Hairston's lab has shown that planktonic "water fleas" (Daphnia), major consumers of suspended algae in lakes, evolved to be tolerant of harmful algae within a decade of the appearance of blooms. This rapid evolution (termed "evolutionary rescue" in conservation biology) raises many intriguing questions, for all environments, not just freshwater: To what extent can we rely on species adapting rather than going extinct when their environment changes? How does the evolution of a species that plays a critical ecological role alter the interactions it has with other species, and the functioning of the entire ecosystem?

Answer:

In the middle of the forest.

Explanation:

They have to bury the remains in the middle of the forest at the Forensic Osteological Research Center in order to study the decomposition of the dead person. By studying the decomposition of dead person we can get a lot of information which can be used in the study of criminal cases and solving of crimes. The middle place in the forest is a perfect place to bury the remains due to presence of huge amount of microbes as well as insect that helps in the decomposition.
