<span>Soln:
•t: in min
•Q(t): quantity of dye in the tank at time t
•r in= 0: rate of dye poured into the tank per min. Since it is fresh water, so it
is zero.
•r out= density of dye×rate of fluid =Q/900×9: rate of dye flowing out.
•Q(0) = 1×900 g: initial amount of dye in the tank.
•{dQ/dt=rin-rout= 0-Q100 Q(0) = 900g•Q(t)=Ce-1/100t
•Q(0) = 900, C= 900, Q(t) = 900e-1/100t
•Q(t) = 0.01·Q(0), Q(0)e-1/100t= 0.01×Q(0),-t100= ln 0.01, t= 460min</span>
HCl + NaOH = NaCl + H₂O
n(HCl)=c(HCl)v(HCl)
n(NaOH)=c(NaOH)v(NaOH)
n(HCl)=n(NaOH)
c(HCl)v(HCl)=c(NaOH)v(NaOH)
c(HCl)=c(NaOH)v(NaOH)/v(HCl)
c(HCl)=0.100mmol/mL*60.0mL/150mL=0.040 mmol/mL = 0.040 mol/L
0.040 M HCl
Answer: A reaction which occurs when equivalent quantities of H" (or ) and OH" are mixed is a neutralization reaction.
Explanation:
When acid and base chemically combine together to form sat and water then it is know as neutralization reaction.
An acidic substance gives hydrogen ions on dissociation and a basic substance gives hydroxide ions on dissociation.
For example, is a neutralization reaction where an acid and base are mixed together to form water.
No salt is formed as because here the reactants are not present as compounds.
In a hydrolysis reaction, water molecule(s) is added to the reactant molecules.
For example,
Oxidation is the process of addition of oxygen to a molecule and removal of hydrogen.
Reduction is the process of addition of hydrogen in a compound and the removal of oxygen atom.
Therefore, we can conclude that reaction which occurs when equivalent quantities of H" (or ) and OH" are mixed is a neutralization reaction.
Answer:
The gravitational pull of the moon and the rotational force of the Earth cause tides to rise and fall across the planet. The species living in coastal areas most affected by changing tides have unique ways of surviving.
So, the answer is B.
