Answer:
Atomic mass of N relative to H is 13.9.
In periodic table mass of N is around 14 RAM
Explanation:
1 mol of ammonia has 1 mol of N, and 3 mole of H
NH₃
1 mol of H weighs 1 g, so the mole of H, present in ammonia are:
1.712 g / 1 g/m = 1.712 mole
Since the ratio is 1:3
1.712 mole/3 = 0.57 mole of N are present in the amonia
To calculate the atomic mass of N relative to H, let's consider it as molar weight.
Molar weight = mass / mole
7.933 g / 0.57 mole = 13.9 g/m
The scientific models are used because they allow scientists to make predictions and make it easier for scientists to avoid using data. option A and C is correct.
<h3>What are scientific models?</h3>
The scientific models are those which is given by scientists to allow them to make prediction about anything particular on which they are working or making research for it some examples are plum pudding model for an atom and bohr's model of an atom etc.
The biggest advantage is that scientists do not have to check the given data which are written into books they can perform their experiment and can conclude the data by performing experiment.
Therefore, scientific models are used because they allow scientists to make predictions and make it easier for scientists to avoid using data. option A and C is correct.

Answer:
H30+(aq)
Explanation:
im almost postive this is correct ,but if not its OH-(aq)
Its impossible coz carbon has isotopes C-12 and C-13 whereas oygen has isotopes 16<span>O, </span>17<span>O, and </span>18<span>O, so impossible. Hope it helps</span>
