Answer:
2KOH + H2SO4 > K2SO4 + 2H2O
Explanation:
firstly the order speaks, you can't have something like OKOH so the other two is eliminated. Then check if the remaining reactions balance
Answer:
Moles of NO = 0.18
Moles of Br2 = 0.18
Explanation:
The given reaction with ICE table is:
Initial 0.64 - -
Change -2x +2x +x
Equilb (0.64-2x) 2x 2x
At equilibrium:
[NOBr] = 0.64-2x
NO = Br2 = 2x
The equilibrium moles of NOBr = 0.46
Moles of NO = Moles of Br2 = 2x = 2(0.09) = 0.18 moles
Answer:
Lithium is a naturally occurring alkali metal, which living organisms ingest from dietary sources and which is also present in trace amounts in the human body. In much higher concentrations, lithium is effective as a medication for mania and mood swings including manic depressive disorders
Answer:
Water and Salt
Explanation:
A neutralization reaction occurs when an acid and a base react to produce water and a salt, and it entails the formation of water from the mixture of H+ and OH- ions.
<span>The following is the order from lowest boiling point to highest based on the types of forces these compounds have:
CO2
CH3Br
CH3OH
RbF
CO2 is a nonpolar molecular compound. The only intermolecular force present is a relatively weak dispersion force, because of the small molar mass. CO2 will have the lowest boiling point. ď‚· CH3Br is a polar molecule. Dispersion forces (present in all matter) and dipoleâ’dipole forces will be present. This compound has the next highest boiling point. ď‚· CH3OH is a polar molecule, which can form hydrogen bonds; these are especially strong dipole-dipole attractions. Dispersion forces and hydrogen bonding are present to give this substance the next highest boiling point. ď‚· RbF is an ionic compound. Ionâ’ion attractions are much stronger than any intermolecular force. RbF has the highest boiling point</span>
