A large quantity if hydronium ions indicates an Arrhenius acid.
Under STP 1 mol of gas has volume 22.4 L.
2C2H2 + 5O2 ------> 4CO2 + 2H2O
from reaction 5*22.4 L 4 *22.4L
given 60L x L
x=(60*4 *22.4)/5*22.4 = (60*4)/5 =48 L of CO2
Answer:
Superscript 239 subscript 94 upper P u
(plutonium-239)
Explanation:
In alpha decay, the element subtracts 4 from its mass number and subtracts 2 from its atomic number.
So if we end with Uranium-235, which has an atomic number of 92:
235+4 = 239
92+2 = 94
Element 94 is Pu, plutonium, and its mass could very well be 239 if it's an isotope. So the answer is Superscript 239 subscript 94 upper P u.
Reactants and products contain the same atoms, but they are rearranged during the reaction, so they are different substances
Partial pressure O2 = total pressure - vapour pressure H2O at 50 deg C
Vapour pressure H2O at 50 deg C = 12.332 kPa
= 96.00 kPa - 12.332 kPa = 83.67 kPa
