Answer:
compounds are elements include an element and a compound
Explanation:
elements in the decomposition reaction is the substance that cannot be separated into simpler substances. Compounds, technically act as a reactant in the decomposition reaction, but since the reaction breakdown one substance into two or more, sometimes it exists in the product
The smallest mass among the choices is Choice (ii):2.3 x 10-3 μg
This is so because, the prefix μ signifies a factor of 10^-6.
For choice I:
- 23 cg means 23 centigrams
For choice II:
- 2.3 × 10-3 μg means 2.3 × 10-9 grams
For choice III:
- 0.23 mg means 0.23 × 10-3 grams
For choice IV:
- 0.23 grams simply means 0.23grams
For choice V:
- 2.3 × 10-2 kg means 23 grams
Ultimately, Choice II represents the smallest mass.

carbon won't have same number of valence electrons as others
Hey there!
Sucrose is C₁₂H₂₂O₁₁.
Find molar mass of sucrose:
C: 12 x 12.01 = 144.12
H: 22 x 1.008 = 22.176
O: 16 x 11 = 176
--------------------------------
342.296 grams
That is the mass of one mole of sucrose.
We have 0.0287.
342.296 x 0.0287 = 9.82
The mass of 0.0287 moles of sucrose is 9.82 grams.
Hope this helps!
