I’m pretty sure it’s A sorry if wrong
Non radioactive carbon 13 has 7 protons per atom.
1 is chemical energy cause thats what gas and electric stoves are
2 is convection
3 is c
The number of particles of atoms depends on the ratio of their composition in the compound
<h3>Further explanation</h3>
Given
5.432 g of table sugar
Required
moles of sample
moles of C, H and O
number of atoms
Solution
Table sugar : Sucrose : C₁₂H₂₂O₁₁
= 5.432 : 342,3 g/mol
= 0.016
C = 12 x 0.016 = 0.192
H = 22 x 0.016 = 0.352
O = 11 x 0.016 = 0.176
C = 0.192 x 6.02 x 10²³ = 1.16 x 10²³
H = 0.352 x 6.02 x 10²³ = 2.12 x 10²³
O = 0.176 x 6.02 x 10²³ = 1.06 x 10²³
