Initial buret reading means the volume of acid taken in the buret and final reading means the remaining volume of acid after experiment
Answer:
Cell Wall
Explanation:
In plant cells, the cell wall is rigid the outer structure that protects the plant cell.
Answer:
Explanation:
The concept applied is the conductivity as it relates to the dissociation and the number of ions in solution. BaCl2 and KBr are ionic solids that will dissociate completely in water to give trivalent and divalent ions respectively.
Benzoic acid on the other hand is a weak acid as such it will not dissociate in water. sugar is a covalent compound.
Hence BaCl2 will have the highest conductivity based on the aforementioned reasons, then followed by KBr ; BaCl2 > KBr > C6H5COOH > C6H12O6
Hey
Matter can neither be created nor destroyed.
Explanation:
This is the law of conservation of matter (mass). One can prove this by performing a simple experiment at home.
Have a great day
The amount, in liters, of the 0.2M NaCl solution required to measure out 3.0 grams of NaCl is 0.25 Liter.
<h3>Stoichiometric problem</h3>
Recall that the molarity of a solution is the ratio of the number of moles of solutes in the solution to the volume of the solution.
Molarity = number of moles/volume in Liters
Thus, a 0.2M NaCl solution contains 0.2 moles of NaCl in 1 Liter of the solution.
But 3.0 grams of NaCl is needed. Recall that:
Number of moles = mass/ molar mass
3.0 grams of NaCl = 3.0 grams/58.88 g/mole = 0.051 moles
If 1 Liter of the solution contains 0.2 moles of NaCl, then the amount of the solution that will contain 0.051 moles (3.0 grams) will be:
1 x 0.051/0.2 = 0.25 Liter
The volume of 0.2M NaCl solution required in order to measure out 3.0 grams of NaCl is 0.25 Liter.
