Answer: 63.88 atm
Explanation:
To answer this, we use the formula PV = nRT since the asumption is that the gas has an ideal behavior
where number of mole = 2.60 mol, R(gas constant) = 0.08205746 L atm/K mol,
T = 251 ∘C = (251 + 273) K = 524 K, Volume = 1.75 L
Making Pressure the subject of the formula, we have
P = nRT/V = 2.6 * 0.08205746 * 524/2.75 = 63.88 atm
Answer:
C
Explanation:
Reduction can be seen through addition (gaining) of electrons, addition of Hydrogen or removal of Oxygen
Mn7+ is reduced to Mn4+ by the addition of 3 electrons.
correct form of question is
Explain the difference between Carbon-12 and Carbon-14. Which version Carbon do you believe is the most stable? Why? What information could help you confirm your prediction?
Answer:
Carbon has three isotopes those are carbon- 12 , carbon - 13 , carbon-14 among these only C-12 and C-13 are stable while C-14 is radioactive.
C-12 has 6 protons and 6 neutrons , C-14 has 6 protons and 8 neutrons. Atoms with equal number of protons and electrons are generally stable however C-12 and C-14 have 6 electrons but due to excess neutrons present in C-14 makes it undergo radioactivity therefore it is unstable.
