Q2. (a) In order to analyze a sample of hydrated oxalic acid, the Bollowing data was collected :0.9g of anhydrous oxalic acid and 0.36g of water were present. Hydrated
Oxali acid has this formula (2001), XH 20.
©). Calculate the mole of anhydrous oxalic acid.
n. H2O4) = m (C2H2O4)

Walt (). Determine the formula of hydrated oxalic acid, (COOH), XH 20.
Formula of oxalic acid is (CzHz04), its usual form is that of the
crystalline hydrate, (COOH)2. 2H₂O
185
G).Calculate the percentage of water in hydrated oxali acid?
​

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).

you didnt put any of the following

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.  

its b it was a compound
