1) CH2 (gas) + Br (solid) -> BrC (solid) + H2 (gas)
2) a) CH4 + Br2 -> CH3Br + HBr
2) b) methane + bromine is substitution because one hydrogen atom from methane is replaced by one bromine atom. addition reaction takes place when one molecule combines with another to form a larger molecule so therefore a molecule from X and bromine combine to form XBr.

A substance has twice the number of particles as 12 grams of carbon-12. How many

klasskru [66]

Answer:

D)2.0

Explanation:

Avogadro’s number represent the number of the constituent particles which are present in one mole of the substance. It is named after scientist Amedeo Avogadro and is denoted by $N_0$ .

Also, it is the number of particles in exactly 12.000 g of isotope carbon 12.

Avogadro constant:-

$N_a=6.023\times 10^{23}$

Thus,

Number of particles as 12 grams of carbon-12 constitutes 1 mole

<u>Twice the number of particles as 12 grams of carbon-12 constitutes 1*2 mole</u>

Thus, moles in the substance = 2.0 moles
