Carbon (C) is an element
Carbon Dioxide (CO2) is a compound
Hydrogen (H) is an element
Sodium Chloride (NaCl) is a compound
A good way to tell whether something is a compound or an element, is that in a compound there is a mixture of different elements. Like in Carbon Dioxide, the symbol is CO2. This shows the carbon (C) and oxygen (O) together. I hope i worded that well enough and this helps :)

Vlad [161]

Answer:

The hours are the independent variable.
The wages/wk earned are ( $11/hr )x( hrs worked ) . This is the dependent variable ( depends on hours worked ) .
The domain is 0 to 30
The range is 0 to 330

Explanation:

The hours are the independent variable and should be plotted on the x-axis .

The wages/wk earned are ( $11/hr )x( hrs worked ) . This is the dependent variable ( depends on hours worked ) and should be plotted on the y-axis

---------------

Let +W+ = wages/wk earned

Let +h+ = hours/wk worked

The equation is:

+W+=+11h+

The domain is 0 to 30

( no hrs worked to 30 hrs worked )

The range is 0 to 330

( no wages eared to +11%2A30+=+330+ earned )

What is missing from the ecosystem during primary succession

Kaylis [27]

Answer:

competition

Explanation:

After an ecosystem has been destroyed because of certain catastrophe and all of the space that it occupied is totally cleared and open for overtaking, the primary succession comes in action. When the primary succession occurs, there's no competition, as pretty much everything has been destroyed from the previously existing ecosystem. The pioneers of the primary succession are organisms that do not require a lot to prosper, such as the mosses and lichens. As they start to cover the barren land, little by little they manage to change the composition of the rocks, thus resulting in the formation of the first soils. As that happens, the secondary succession comes on the horizon as now it has conditions for it, so the species from it overtake and replace the species form the primary succession.
