Explanation:

1) The main constituting element in paper , diamond  and cloths is carbon atom.This because carbon atom has unique property of creating strong covalent bonds with other carbon atoms which give rises to complex organic  structures.

2) There two oxides formed by carbon which are : carbon-dioxide CO_2and carbon monoxide CO.

Structure are given in an image.

3) In molecule of methane there is a 1 mol of carbon.

Methane = CH_4

In 1 molecule of ethene there are two carbon atom double bonded to each other.

Ethene = C_2H_4

Electron dot structure of methane and ethene are given in an image

Answer 1) Carbon - It is the element which is the main constituent of the paper in the form of cellulose, diamond is made of completely carbon and clothes are mostly made from carbon based fibers. Also, it forms covalent bonds with itself and other elements too because it has 4 valence electrons in its valence shell so, it can either donate or accept electrons to attain a stable octet state.


Answer 2) The electron dot structure of the oxides of carbon are of two types;

i) CO and ii) CO_{2}


The images are attached for the electron dot structures.


Answer 3) The structure of methane and ethene is attached in the image.

An iron ore was found to contain 92.0% pyrite (fool's gold). Pyrite has the formula FeS2and is 46.5% iron. How many grams of iro
Liula [17]
Firstly calculate the grams in the last 8 percent before moving onto the pyrite section.
50.8x0.08=4.064g
We know that iron ore in this case has 92 percent pyrite which contains 46.5 percent iron so we do 50.8x0.92=46.736g from this we need to find 46.5 percent of the iron content in the 92 percent pyrite section then add this answer to the 8 percent of iron ore we found at the start.46.736x0.465=21.73224g
21.73224g+4.064=25.79624g of iron ore 25.8g(3sf)
