the ink will mix with the entire water.Even though it is dense than water,it will mix with it
The iodine solution in the baggie would diffuse into the beaker containing the starch. The iodine molecules would interact with the starch molecules, resulting in the formation of a dark blue or black color, indicating the presence of a starch-iodine complex.
Without boron, the glass beaker may not be able to withstand sudden temperature changes and could shatter due to thermal shock when placed in iced water. This is because borosilicate glass, which contains boron, has a lower coefficient of thermal expansion and is better suited for rapid temperature changes.
The phospholipids would align themselves at the interface between the oil and water layers due to their amphipathic nature. This arrangement forms a lipid bilayer with hydrophobic tails in the oil and hydrophilic heads in contact with water. This process mimics the formation of cell membranes in living organisms.
The process is called diffusion, where the sugar particles move from an area of high concentration (the lump of sugar) to an area of low concentration (the rest of the water) until they are evenly distributed.
If Ag+ is added to a dilute solution containing FeCl4-, a white precipitate of AgCl would form. This is because Ag+ ions react with Cl- ions to form AgCl, causing the color of the solution to change from the original color of the FeCl4- solution to white due to the formation of the precipitate.
You need dayan 2 hours
If a beaker containing glucose is permeable to glucose, then the glucose will go through the beaker.
Nothing............. But if the water has any gas dissolved in it, these may form bubbles.
Squeezing the dropper will create a vacuum inside it, causing the liquid to be drawn up into the dropper. When you release the pressure, the liquid will be dispensed in a controlled manner.
The iodine solution in the baggie would diffuse into the beaker containing the starch. The iodine molecules would interact with the starch molecules, resulting in the formation of a dark blue or black color, indicating the presence of a starch-iodine complex.
It will evaporate
If a glowing splint is held at the mouth of a beaker containing potassium and water, the potassium will react violently with the water, producing potassium hydroxide and hydrogen gas. The hydrogen gas is highly flammable, and as it is released, it can ignite from the heat of the reaction, resulting in a small explosion or fire. The gas evolved during this reaction is hydrogen.
It'll go out
it will happen soon
After the total evaporation of water a small solid residue can remain in the beaker.
It will stop burning
After an hour in a beaker containing concentrated sugar solution, the two cubes of potato will likely shrink in size. This occurs due to osmosis, where water from the potato cubes moves out into the sugar solution to balance the concentration gradient. As a result, the cubes will lose water and become more dehydrated, leading to a wrinkled or shriveled appearance.
