Explanation:
When solid cadmium sulfide reacts with an aqueous solution of sulfuric acid then the reaction will be as follows.
Hence, ionic equation for this reaction is as follows.
Therefore, net ionic equation for this reaction is as follows.
Answer:
B.
Explanation:
Everything else is not a drawback, it is a benefit.
B. Troposphere, stratosphere, mesosphere, thermosphere
Answer:
-537.25 kJ/mol is the standard enthalpy of formation of solid glycine.
Explanation:
Standard enthalpy of formation of oxygen gas= 
Standard enthalpy of formation of carbon dioxide= 
Standard enthalpy of formation of water = 
Standard enthalpy of formation of nitrogen gas= 
Standard enthalpy of formation of glycine = 
Enthalpy of the reaction = 
=
On rearranging :
-537.25 kJ/mol is the standard enthalpy of formation of solid glycine.
Answer i) The molarity for the solution of
prepared after dilution from 10 mL of 0.33 M solution to 1 L solution is
3.3 X 
,
by using this formula.
So, Molarity of unknown solution = (10 X 0.33) / 1000 =
3.3 X .
Answer ii) When you dilute the solution prepared in question (1 ) to 50.0 mL from 5.00 mL of 1L solution then, you should take an aliquot of 5 mL and then dilute upto 50 mL that will be the result of another 10 times dilution which will result in the new concentration as
0.00033 M for
solution.
Answer iii)
Question iii is incomplete. Complete question is attached below;
Solution:
Given: A = 0.982, b = 1 cm, c = 0.0001 M
we know that, A = ebc
Therefore, ∈ = A/bc = 0.982/(1 X 0.0001) = 9820 M-1 cm-1.
Thus, molar absorptivity of solution is 9820 M-1 cm-1.
