That would be an ionic bond since it has electrons to spare, rather than a convalent bond where all the electrons are taken up thus it is not a good conductor
Answer:
V₂ = 317 L
Explanation:
Given data:
Initial number of moles of hydrogen = 18.9 mol
Initial volume of gas = 428 L
Final volume = ?
Final number of moles = 14.0 mol
Solution:
According to the Avogadro law,
Number of moles of gas is directly proportional to the volume of gas at constant temperature and pressure.
Mathematical expression:
V₁/n₁ = V₂/n₂
V₁ = Initial Volume of balloon
n₁ = initial number of moles
V₂ = Final volume of balloon
n₂ = Final number of moles
Now we will put the values.
428 L / 18.9 mol = V₂/ 14 mol
V₂ =428 L × 14 mol / 18.9 mol
V₂ = 5992 L /18.9
V₂ = 317 L
The nuclear equation :
₈₂²¹⁴Pb ⇒ ₈₃²¹⁴Bi + ₋₁⁰e
<h3>Further explanation
</h3>
Given
₈₂²¹⁴Pb
beta β ₋₁e⁰ particles
Required
Nuclear equation
Solution
Radioactivity is the process of unstable isotopes to stable isotopes by decay, by emitting certain particles,
-
alpha α particles ₂He⁴
- beta β ₋₁e⁰ particles
- gamma particles ₀γ⁰
- positron particles ₁e⁰
- neutron ₀n¹
The principle used is the sum of the atomic number and mass number before and after the decay reaction is the same
The reaction
₈₂²¹⁴Pb ⇒ X + ₋₁⁰e
The element X has
-the atomic number = 82 + 1 = 83
-the mass number = 214
In the periodic system, the element with atomic number 83=Bismuth
Answer: It is not renewable
Charcoal contains high amount of CO2 emission.
Charcoal when burned emits radiation and even clean coals produces methane.
