V₁ = <span>178 mL - initial volume
</span>T₁ = 0 ⁰C = 273K - initial temperature
V₂ = <span>211 mL - final volume
</span>T₂ =? - final temperature
According to Charles's law when pressure is constant the Kelvin temperature and the volume will be directly related:
V₁/T₁=V₂/T₂
178/273=211/T₂
0.65=211/T₂
T₂=324K= 51⁰C
HCl is a strong acid therefore complete ionisation takes place
HCl ---> H⁺ + Cl⁻
1 mol of HCl dissociates to form 1 mol of H⁺
NaOH is a strong base therefore complete ionisation takes place
NaOH ---> Na⁺ + OH⁻
1 mol of NaOH dissociates to form 1 mol of OH⁻ ions
equal number of moles of HCl and NaOH will dissociate to give out an equal number of moles of H⁺ and OH⁻ ions.
H⁺ + OH⁻ --> H₂O
equal amount of H⁺ and OH⁻ together forms H₂O
since all the H⁺ and OH⁻ have now reacted to form water molecules the solution now becomes neutral as there are no excess H⁺ ions to make the solution acidic and no excess OH⁻ ions to make the solution basic.
Therefore the solution will be neutral.
Answer:
relating to or characteristic of a microorganism, especially a bacterium causing disease or fermentation.
Explanation:
ex: "skin is a major source of microbial contamination during a surgical procedure"
Well, from what i remeber, u need a charge at each end of the wire, then u turn it on by a generator, and the elecricity thats in the charges, or batteries, travels up the wires.
hope this helps.
