Answer:
5.52 g
Explanation:
First we <u>convert the given masses of both reactants into moles</u>, using their <em>respective molar masses</em>:
- 6.30 g NH₃ ÷ 17 g/mol = 0.370 mol NH₃
- 1.80 g O₂ ÷ 32 g/mol = 0.056 mol O₂
Now we <u>calculate with how many NH₃ moles would 0.056 O₂ moles react</u>, using the<em> stoichiometric coefficients</em>:
- 0.056 mol O₂ *
= 0.045 mol NH₃
As there more NH₃ moles than required, NH₃ is the excess reactant.
Then we calculate how many NH₃ moles remained without reacting:
- 0.370 mol NH₃ - 0.045 mol NH₃ = 0.325 mol NH₃
Finally we convert NH₃ moles into grams:
- 0.325 mol NH₃ * 17 g/mol = 5.52 g
In quantum matter, all things in the world are made up of even smaller particles than the atom. These are called the subatomic particles: neutron, proton and electron. A beta particle is simply an electron. It is an electromagnetic particle or wave. Electromagnetic particles are high-energy particles that are emitted by the atom during radioactive decay. Since it is an electron, its charge must be -1 and it must come from outside the nucleus of the atom. From the choices, the answers would be:
<span>is electromagnetic energy
</span><span>has a -1 charge</span>
Cloudy skies and precipitation. Rain is normally caused by water vapor within the condensation of the low pressure system.
Molecular mass= (14.01∗1)+(1.008∗3)
14.01+3.024=17.03g/mol
