According to picture below, answer is d.c4h2n2o4 and c2hno2.
Molecular formula is chemical formula that shows the total number and kinds of atoms in a molecule, but not their structural arrangement (in this case C₄H₂N₂O₄). Molecular formula shows that compound has four carbon, two hydrogen, two nitrogen and four oxygen atoms.
Empirical formula gives the proportions of the elements present in a compund but not the actual numbers or arrangement of atoms. C : H : N : O = 2 : 1 : 1 :2.

How many joules are needed to warm 675 grams of water (specific heat= 4.186 J/g degrees Celsius) from 12 degrees Celsius to 85 d
Naya [18.7K]
85-12 = 73 degrees needed
4.186 J/degree Celsius, so 
73 degrees * 4.186 J/degree = 305.578 J to raise 1 gram 73 degrees
there are 675 grams, so 305.578 * 675 = 206265.15 J

2.06 x 10^5 J are needed
