Tying marshmallows utilising toothpicks together was difficult about building the model
Building the construct was challenging because of the toothpicks used to connect the marshmallows.
• The Salt Model consists of three layers that can be stacked on top of one another to form a NaCl unit cell.
Using the model in two different orientations is possible if the layers are connected.
• As shown by the salt model, the majority of basic inorganic compounds are composed of ions that interchange endlessly rather than discrete molecules.
Little marshmallows could serve as an analogy for the tiny sodium atoms.

Answer:
34.23 g.
M = (no. of moles of solute)/(V of the solution (L)).
Sodium , bromine zinc magnesium sulphur nitrogen potassium oxygen lead
Mass = molecular mass x mol
mass = 176.128 x 0.000142
mass = 0.025 g (3 s.f)
Answer:
The correct answer is True.
Explanation:
In the kidney, the handle of Henle is a fork-like tube located in the nephrons. It is the portion of the nephron that leads from the proximal contoured tubule to the distal contoured tubule. The primary filtrate from the glomerulus passes into the proximal contoured tubule, which connects to the descending branch of the loop of Henle, which has low permeability to ions and urea (solutes) but is very permeable to water.
Have a nice day!
