Per hour-68x60=4080
Per day-4080x24=97920
Per week-97920x7=685440
PbCl2--->Pb2+ + 2Cl-
The mass of PbCl2 is =mass of the beaker+Pbcl2 minus mass of the beaker
that is 62.19-57.77g= 4.42grams
moles of PbCl2= 4.42g/278g/m0l = 0.0159moles
concentration of (Pb2+)
since mole ratio of PbCl2 to Pb2+ is 1:1 therefore the moles of Pb2+ is also 0.0159moles
concentration =0.0159/100 x1000=0.159M
concentration of CI- is two time that of Pb2+ from the equation above therefore concentration of Cl- = 0.159 x2 =0.318M
The second one is correct. Alleles on homologous chromosomes determine traits
Sugar dissolves faster in a warm liquid than in a cold liquid – this is an example of how temperature influences the reaction rate....
Yes it is. Another example is surface area of reactants, powdered iron fillings would react faster in HCl than iron lumps.
Also your beverage would also dissolve faster in hot water than in cold water, this is also an example of how temperature affects rate of reaction.
There are other examples that can be stated as well.
Answer: The final volume will be 2.89 L.
Explanation:
Given:
,
, 
= 101.3 kPa
Convert kPa to atm as follows.

= 1520 torr
Convert torr into atm as follows.

Formula used to calculate final temperature is as follows.

Substitute the values into above formula as follows.

Thus, we can conclude that the final volume will be 2.89 L.
