An ion has 14 neutrons, 10 electrons, and a mass number of 27 what element

nasty-shy [4]

The ion is Al³⁺

mass number - number of neutrons= atomic number

27 - 14 = 13

Aluminum has an atomic number of 13, thus we know this is the metal in question. Also, because the aluminum has only 10 electrons, (3 less than a neutral atom of aluminum would have), its charge must be 3+

The reform reaction between steam and gaseous methane (CH4) produces "synthesis gas," a mixture of carbon monoxide gas and dihyd

kenny6666 [7]

Answer:

The answer is " $= 0.078 \ kg \ H_2$ ".

Explanation:

calculating the moles in $CH_4 =\frac{PV}{RT}$

$=\frac{(0.58 \ atm) \times (923 \ L) }{ (0.0821 \frac{L \cdot atm}{K \cdot mol})(232^{\circ} C +273)}\\\\=\frac{(535.34 \ atm \cdot \ L) }{ (0.0821 \frac{L \cdot atm}{K \cdot mol})(505)K}\\\\=\frac{(535.34 \ atm \cdot \ L) }{ (41.4605 \frac{L \cdot atm}{mol})}\\\\= 12.9 \ mol$

Eqution:

$CH_4 +H_2O \to 3H_2+ CO \ (g)$

Calculating the amount of $H_2$ produced:

$= 12.9 \ mol CH_4 \times \frac{3 \ mol \ H_2 }{1 \ mol \ CH_4}\times \frac{2.016 g H_2}{1 \ mol \ H_2}\\\\= 78 \ g \ H_2 \\\\= 0.078 \ kg \ H_2$

So, the amount of dihydrogen produced = $0.078 \frac{kg}{s}$

What is the total number of moles (n) of electrons exchanged between the oxidizing agent and the reducing agent in the overall r

Sergeu [11.5K]

Answer:
5 moles of electrons

Explanation:

The balance equation is as follow,

 5 Ag⁺ + Mn⁺² + 4 H₂O → 5 Ag + MnO₄⁻ + 8 H⁺

Reduction of Ag:

Ag⁺ + 1 e⁻ → Ag
Or,
5 Ag⁺ + 5 e⁻ → 5 Ag

Oxidation of Mn:

Mn⁺² → MnO₄⁻ + 5 e⁻

Result:
Hence 5 moles of Ag⁺ accepts 5 electrons from 1 mole of Mn⁺².

Isotopes of carbon differ with the respect to the number of

hodyreva [135]

Answer:

Neutrons.

Explanation:

Isotopes can be defined as the atom of an element that has the same number of protons but different number of neutrons. This ultimately implies that, the isotopes of an element have the same atomic number (number of protons) but different atomic mass (number of nucleons).

The isotope of an element is denoted by $X^{A}_{Z}$

Where; X is the symbol of the element.

A is the atomic mass or number of nucleons.

Z is the atomic number or number of protons.

Therefore, the number of neutrons = A - Z

Isotopes of carbon differ with respect to the number of neutrons.

Basically, there are three (3) Isotopes of Carbon and these are;

1. Carbon-12: it has an atomic mass of 12 with 6 numbers of proton and neutron respectively.

2. Carbon-13: it has an atomic mass of 13 with 6 numbers of proton and 7 numbers of neutron.

3. Carbon-14: it has an atomic mass of 14 with 6 numbers of proton and 8 numbers of neutron.

Which process releases energy that eventually produces lightning in the thunderstorm?

Ira Lisetskai [31]

Answer:

Answer: B. Water condenses to form clouds.

Explanation:

When the moisture condenses, this results in the release of energy. The energy causes the air to be warm and results in the rise of air in the upper atmosphere. This process results in the instability in the atmosphere and cumulonimbus clouds are formed. These clouds support lightening during a thunderstorm.
