Given:
n = 12 moles of oxygen
T = 273 K, temperature
p = 75 kPa, pressure
Use the ideal gas law, given by
where
V = volume
R = 8.3145 J/(mol-K), the gas constant
Therefore,
Answer: 0.363 m³
Answer:
A)It has too many neutrons
Explanation:
Electrons are emitted from the nucleus when a neutron is converted to a proton, an electron and a neutrino. This process is popularly known as beta emission. It reduces the neutron-proton ratio of a nuclide. The neutrino is a particle of zero mass and zero charge that carries off the excess energy and balances spins.
The loss of an electron from the nucleus occurs when there are too many neutrons in the nucleus. The process of beta emission usually reduces the number of neutrons in an atom thereby decreasing the neutron-proton ratio.
Answer:
The answer to your question is 52.35 g of O₂
Explanation:
mass of oxygen = ?
mass of KClO₃ = 66.8 g
Chemical balanced reaction
KClO₃ ⇒ 2 KCl + 3O₂
Process
1.- Calculate the molar mass of KClO₃ and Oxygen
KClO₃ = 39 + 35.5 + (16 x 3) = 122.5 g
O₂ = 16 x 6 = 96 g
2.- Write proportions to solve this problem
122.5 g of KClO₃ ----------------- 96 g of O₂
66.8 g ----------------- x
x = (66.8 x 96) / 122.5
x = 6412.8/122.5
x = 52.35 g of O₂
