answer
1.a element because it can change from solid to liquid form and can not freeze again, andnot combined as a compound
b. because of the solid into the liquid compound is need at the heat of nature so that heatabsorption by the substance
c.karena element always at room temperature and is stable and what if in the heat or coldit will change its shape alone
2.kalau in my case is not appropriate because it is more than the weight of the object atthe initial reaction of 10 g.sedangkan law of conservation of that time period is alwaysconstant seblum reaction or after the reaction occurred
3.yaitu by the combustion reaction so that elements can be separated from each other
4. Mendeleev predicted correctly in my opinion he is able to predict that one day will findelements in new and mnyediakan place, because the model formulation is based on theMendeleev periodic table atomic mass increases and the nature kemiripanya.
