You mix 35mL of 0.54M NaI with 14mL of 0.84M Pb(NO3)2.
Answer: A. The compound CuCl is 500 times less soluble in sea water than it is in pure water.
pure water.
Explanation:
Any change in the equilibrium is studied on the basis of Le-Chatelier's principle.
This principle states that if there is any change in a equilibrium reaction, the equilibrium will shift in a direction so as to minimize the effect.
Thus when a common ion is introduced to an equilibrium reaction, the equilibrium will shift in a direction where the concentration of common ion is decreasing.
When common ion such as 
from NaCl in sea water is introduced to an equilibrium reaction, the equilibrium will shift in a direction where the concentration of common ion is decreasing i.e. in the left side and thus solubility of CuCl further decreases.
Answer:
False
Explanation:
Electric fields are invisible to the human eye, it is similar to magnetism and radio waves.
Answer: The formula of the hydrated alumina is 
Explanation:
Decomposition of hydrated alumina is given by:
Molar mass of 
= 101.96 g/mol
According to stoichiometry:
(101.96+18x) g of 
decomposes to give 101.96 g of
Thus 5.000 g of
decomposes to give=
of H_2O
But it is given 5.000 g of a sample of hydrated salt was found to contain 2.6763 g of unhydrated salt
Thus we can equate the two equations:
Thus the formula of the hydrated alumina is
Heya!
Sulfur dioxide - <em>( SO2 )</em>
<u><em>Answer:</em></u>
- <em>Sulfur dioxide is a common pollutant caused due to the burning of coal,Is very harmful for the environment and health.</em>
<u><em>Effects:</em></u>
- Health effects-Sulfur dioxide effects the respiratory system which includes the functioning of lungs,respiratory track and causes infections,can also effect and irritate the eyes and causes aggravating conditions such as asthma and chronic bronchitis.
- As most sulfur dioxide air pollution comes from the burning of coal and oil in power plants. It is a emitted by trains, large ships and other diesel objects that burns alota sulfur fuel so this also effects the environment like plants and others as the air lacks oxygen ,but with more sulfur dioxide.
<em>Hope this helps!</em>
<em>Have a nice day!:)</em>
