The answer would be a. C2H4(ethylene)
1C2H4+3O2~>2CO2+2H2O
The given complex ion is as follow,
[Ru (CN) (CO)₄]⁻
Where;
[ ] = Coordination Sphere
Ru = Central Metal Atom = <span>Ruthenium
CN = Cyanide Ligand
CO = Carbonyl Ligand
The charge on Ru is calculated as follow,
Ru + (CN) + (CO)</span>₄ = -1
Where;
-1 = overall charge on sphere
0 = Charge on neutral CO
-1 = Charge on CN
So, Putting values,
Ru + (-1) + (0)₄ = -1
Ru - 1 + 0 = -1
Ru - 1 = -1
Ru = -1 + 1
Ru = 0
Result:
<span>Oxidation state of the metal species in each complex [Ru(CN)(CO)</span>₄]⁻ is zero.
Answer:
The correct answer is d.hydrogen peroxide H₂O₂H₂O₂
Explanation:
Substances can be found in nature in different <em>aggregation states. </em>
Agreggation states can be liquid, gas or solid.
The problem asks about which substance can be found in room temperature as <em>liquid.</em> Each subtances has different physical and chemical properties that determines in which state you can find them at room temperature.
Hydrogen peroxide is the only substance listed that is in liquid state at room temperature, all other substances are in gas state at room temperature.
Answer:
Amount of Na = 2.17moles
Explanation:
Mass of Na = 50g
Molar mass of Na = 23g/mol
Amount of mole = mass/molar mass
Amount of mole = 50/23
Amount of mole = 2.17moles
B I hope it’s right I don’t really help a lot but yeah lol
