How many moles of c atoms are in 1 mol of sucrose (c12h22o11)?

Use dimensional analysis to solve problems like these.

1 mol C12H22O11 * 12 mol C atoms / 1 mol C12H22O11 = 12 mol of C atoms

Alternatively, you can also think of Sucrose as a molecule with 12 atoms of Carbon, 22 atoms of Hydrogen, and 11 atoms of Oxygen. Each of the atoms represent one mole and since you have 12 Carbon atoms, it would equal to 12 moles of Carbon atoms.

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.  

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
