A large unstable nucleus becomes tinier and emits an alpha particle during Alpha decay. 4/2He or the alpha particle that consists of two protons and two neutrons can be discharged from the nucleus during the disintegration of radioactive decay. It has a charge of positive 2.

Answer: The product of the radioactive decay $_2^4\textrm{He}$ is called as alpha particle.

Explanation:

Radioactive decay of the nuclei happens when a nuclei has to attain some sort of stability. It undergoes various decay processes and releases various particles during these decay process. The types of particles released are:

Alpha particle: These are released during alpha decay. The particle released carry a mass of +4 units and a charge of +2 units. It is represented as $_2^4\alpha$
Beta particle: These are released during beta decay. The particle released carry a mass of 0 units and a charge of -1 units. It is represented as $_{-1}^0\beta$
Gamma particle: These are released during gamma decay. The particle released does not carry any charge and is electrically neutral. It is represented by $\gamma -\text{particle}$

Hence, the correct answer is alpha particle.

A gaseous hydrogen and carbon containing compound is decomposed and found to contain 82.66% carbon and 17.34% hydrogen by mass.

Doss [256]

For the answer to the question above, I'll show the solution to my answers

moles C = 82.66 g/ 12.0111 g/mol=6.882
moles H = 17.34 g/ 1.008 g/mol=17.20 

17.20/ 6.882 =2.5 => H 
6.882 / 6.882 = 1 => C 

to get whole numbers multiply by 2 
C2H5 ( empirical formula Molar mass = 29.062 g/mol) 

n = pV/RT = 0.732 x 0.158 L/ 0.08206 x 298 K= 0.00473 
molar mass = 0.275/ 0.00473 =58.1 g/mol 

58.1 / 29.062 = 2 

multiply by two the empirical formula 

C4H10
