Radon-219 decays to radon-218 by releasing... a. a positron b.a muon O c. a neutron O d. an electron O e. a proton

MrRa [10]

Answer: Option (c) is the correct answer.

Explanation:

A positron is denoted as $^{0}_{+1}e$ , a neutron is denoted as $^{1}_{0}n$ , an electron is denoted as $^{0}_{-1}e$ , and a proton is denoted as $^{1}_{1}p$ .

Therefore, when $^{219}Rn$ will decay into $^{218}Rn$ this means there occurs decrease in its mass number. Hence, it means a neutron will be releasing during this reaction.

The reaction will be as follows.

$^{219}Rn \rightarrow ^{218}Rn + ^{1}_{0}n$

Show your calculation by uploading a picture. Calculate the molar mass of ammonia, NH3

Cloud [144]

Answer:

17.04 g/mol

Explanation:

Molar Mass of NH₃

we know that

Nitrogen has 14.01 gram/mol

And Hydrogen has 1.01 gram/mol

but we have 3 Hydrogens So we multiply

1.01 by 3 i.e., 3.03

Now, add

14.01

+ 3.03

17.04

So, The molar mass of ammonia, NH₃ is

17.04 g/mol
