In chemical weathering a new substance is usually formed after the weathering takes place.
From the question the layer of statue made by metal will likely form oxides of those metals. Example Silver will react with oxygen to form an entirely new substance like silver(i)oxide.
Answer:
The answer to your question is: letter B
Explanation:
Data
3.58 x 10⁴ cal to joules
1 calories --------------- 4.184 joules
3.58 x 10⁴ cal----------- x
x = ( 3.58 x 10⁴ x 4.184) / 1
x = 149787.2 joules
x = 1.5 x 10⁵ J
Answer:
1.08 grams
Explanation:
first, we need to find the number of moles
we divide 12.1/22.4=0.54 moles
we multiply the number of moles with the molecular mass 0.54x2=1.08g
Answer:
elements and compounds can only be liquids or solids, but mixtures can be solids, liquids or gases
Explanation:
Element: A substance that is made up of only one type of atom. Compound: A substance that is made up of more than one type of atom bonded together. Mixture: A combination of two or more elements or compounds which have not reacted to bond together; each part in the mixture retains its own properties.
I believe the correct answer is 11 g
