CO + 2 H2 → CH3OH
<span> find # of mols in each reactants, </span>
<span>152500 g CO x 1 mol CO / 28.01g CO = 5444 mol CO </span>
<span>24500 g H2 x 1 mol H2 / 2.02 g H2 = 12129 mol H2 </span>
<span>mol ratio between CO and H2 is 1:2, which means each mol of production of CH3OH need 1 mol of CO and 2 mol of H. </span>
<span>H2 is enough to produce 6064 mols of CH3OH but there are only 5444mol of CO. </span>
<span>5444 mol CH3OH x molar mass of CH3OH / 1 mol CH3OH </span>
<span>= 174371 g = 174.4 kg</span>
Answer:
1. Alpha particles consist of two protons and two neutrons.
Explanation:
Alpha particles are generally produced in the process of alpha decay, a radio active decay in which an atom loses an helium atom.
AN alpha particle is identical to the helium particle. The helium particle has mass number of 4 and atomic number of 2. This means;
Number of protons = 2
Number of neutrons = Mass Number - Atomic Number = 2
The correct option is option 1.
The correct answer is : <span>Neon is inert because its outermost shell is complete.
Ne atomic number is 10 and has an electronic configuration of 1s</span>² 2s² 2p⁶.The outer shell is complete therefore Ne is inert, in other words inactive as its very stable with a complete outer shell.
Nitrogen is not inert as its atomic number is 7 and electronic configuration is 1s² 2s² 2p³. therefore valence electrons are 5, it needs 3 more electrons to gain the complete outer shell configuration. Therefore this statement is incorrect.
F has 7 valence electrons and needs only one more electron to complete its outer shell whereas O has 6 valence electrons and needs 2 electrons to complete its outer shell. Since F only needs one electron and O needs two electrons, F is more reactive than O therefore third statement is incorrect
F is more reactive than Ne as Ne is inert, however F needs to gain one electron and not lose, to fill its outermost shell therefore this statement too is incorrect
The answer is C. more better. Like I'm better everyday :D
GIVE ME MORE QUESTIONS FOR MORE POINTS PLEASE :D
have a nice day :) happy new year
Gasoline contains C and H atoms. During combustion, the carbon (C) from the fuel combines with oxygen (O2) from the air to produce carbon dioxide (CO2).
2 C8H18 + 25 O2 → 16 CO2 + 18 H2O.
Combustion reactions release large amounts of heat. They have negative enthalpy. A negative enthalpy represents an exothermic reaction, releasing heat. This reaction is spontaneous and exothermic, since we can obtain energy from the reaction; the ΔG (free energy) is negative (So 1 is true).
ΔG < 0, so the free energy of the system decreases with the reaction. Remember that when there is a negative ΔG the reaction goes from higher free energy to lower free energy, like in this case.
