Hello there!

The answer is 92000 tons per year

The palmetto landfill supplies methane (CH₄) for the BMW plant there. The gas is used to operate the turbines used to power the BMW campus. It reduces carbon dioxide emissions because the combustion of methane produces fewer CO₂ than the combustion of other gases like propane or butane, which are commonly used for powering turbines.

A compound made of two elements, iridium (Ir) and oxygen (O), was produced in a lab by heating iridium while exposed to air. The

1) Compund Ir (x) O(y)

2) Mass of iridium = mass of crucible and iridium - mass of crucible = 39.52 g - 38.26 g = 1.26 g

3) Mass of iridium oxide = mass of crucible and iridium oxide - mass of crucible = 39.73g - 38.26g = 1.47g

4) Mass of oxygen = mass of iridum oxide - mass of iridium = 1.47g - 1.26g = 0.21g

5) Convert grams to moles

moles of iridium = mass of iridium / molar mass of iridium = 1.26 g / 192.17 g/mol = 0.00656 moles

moles of oxygen = mass of oxygen / molar mass of oxygen = 0.21 g / 15.999 g/mol = 0.0131

6) Find the proportion of moles

Divide by the least of the number of moles, i.e. 0.00656

Ir: 0.00656 / 0.00656 = 1

O: 0.0131 / 0.00656 = 2

=> Empirical formula = Ir O2 (where 2 is the superscript for O)

Answer: Ir O2

The production of new skin cells to replace those that have been lost is an example of what characteristic of life?
Alchen [17]

The production of new skin cells is example of regeneration.

Regeneration is process of replacing or restoring not just skin cells, but also other cells in the human organism.

Skin regeneration is replacement of damaged tissue with new tissue.

There are two ways of skin regeneration:

1) reconstruction is a process of rebuilding of damaged skin cells

2) restoration is process of replacing broken cell skins

Epidermal stem cells are those who produces new daughter cell skins.

Epidermal stem cells are in the lowest layer of the skin.
