Answer:
D. freezing point depression
Explanation:
Answer:
D
Explanation:
solution made by mixing 100 mL of 0.100 M HClO and 50 mL of 0.100 M NaOH Can resist pH change when there is little addition of either acid or base, hence it is a buffer solution
Number of moles of solute in 16.55 mL of 0.1475 M M2Cr3O7 is 0.00244 moles.
<u>Explanation:</u>
The properties and behavior of many solutions depend not only on the nature of the solute and solvent but also on the concentration of the solute in the solution. Molarity (M) is the concentration of a solution expressed as the number of moles of solute per liter of solution:
,
Here ,
.
⇒ 
⇒ 
⇒ 
⇒ 
Therefore, Number of moles of solute in 16.55 mL of 0.1475 M M2Cr3O7 is 0.00244 moles.
To determine this simply use the coefficients in the balanced equation to relate the moles of oxygen to CO2.
Here it would be 1 : 2.
Answer:
Explanation:
Just move the decimals according to the conversions. khdbdcm
For example, 0.044km, using khdbdcm, from k you have to move 3 spaces to reach "b" or the standard unit.
