I know that a positively charged electron is called a positron, but is there such thing as a negatively charged proton?

A positivey charged subatomic ion is a <em>proton</em> which is in the nucleus

A negitively charged subatomic ion is an electon which is found outside the nucleus in the electron cloud

A neutral subatomic ion is a <em>neutron </em>which is also in the nucleus

<h2>Answer:</h2>

<u>There is no such thing as a negatively charged proton</u>

<h2>Explanation:</h2>

A positively charged particle inside the atom is called a proton. and a negatively charged particle is called electron. Both the particles have same charged magnitude but their effect is different. Electron behaves negatively while proton positively. There are many subatomic particles. A positron is the anti-particle of an electron. It has the same mass as the electron, but a positive charge. But there is no such thing as a negatively charged proton.

For the following reaction, 22.9 grams of nitrogen monoxide are allowed to react with 5.80 grams of hydrogen gas. nitrogen monox

ololo11 [35]

Answer:

1) Maximun ammount of nitrogen gas: $m_{N2}=10.682 g N_2$

2) Limiting reagent: $NO$

3) Ammount of excess reagent: $m_{N2}=4.274 g$

Explanation:

<u>The reaction </u>

$2 NO (g) + 2 H_2 (g) \longrightarrow N_2 (g) + 2 H_2O (g)$

Moles of nitrogen monoxide

Molecular weight: $M_{NO}=30 g/mol$

$n_{NO}=\frac{m_{NO}}{M_{NO}}$

$n_{NO}=\frac{22.9 g}{30 g/mol}=0.763 mol$

Moles of hydrogen

Molecular weight: $M_{H2}=2 g/mol$

$n_{H2}=\frac{m_{H2}}{M_{H2}}$

$n_{H2}=\frac{.5.8 g}{2 g/mol}=2.9 mol$

Mol rate of H2 and NO is 1:1 => hydrogen gas is in excess

1) <u>Maximun ammount of nitrogen gas</u> => when all NO reacted

$m_{N2}=0.763 mol NO* \frac{1 mol N_2}{2 mol NO}*\frac{28 g N_2}{mol N_2}$

$m_{N2}=10.682 g N_2$

2) <u>Limiting reagent</u>: $NO$

3) <u>Ammount of excess reagent</u>:

$m_{N2}=(2.9 mol - 0.763 mol NO* \frac{1 mol H_2}{1 mol NO})*\frac{2 g H_2}{mol H_2}$

$m_{N2}=4.274 g$
