The marbles will pulverize the salt crystals so much that the salt looks like a powder but the salt has actually been reduced to very small crystals.
Graduation marks on a beaker are the lines or measurements used to indicate volume or level of liquid inside the beaker. They help in accurately measuring the amount of liquid being poured or mixed in the beaker.
The dashed line in the beaker typically represents the level of the solution or substance inside the beaker. It is used to show the volume of liquid present and often serves as a reference point for making measurements or dilutions.
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
If left in a beaker for a while, water can gradually evaporate due to exposure to air, especially under warm conditions. This may result in a decrease in the water level in the beaker. If the beaker is left uncovered, impurities from the air or container may also potentially contaminate the water over time.

Fill a market beaker to a specific measured volume. (Eg. 50cm cubed, make sure you have not filled the beaker with water). Now place the object in the beaker with water. The water level should rise (Eg. from 50cm cubed to 60cm cubed). The difference in the original volume and the final volume is the volume of the object. That is the water displacement method.
To determine the mass of the beaker and fluid on a triple beam balance, you would first place the beaker filled with the fluid on the balance. Then, you adjust the sliders on the beams until the balance is level, indicating that the total mass is equal to the sum of the beaker's mass and the fluid's mass. The reading on the balance will give you the combined mass of both the beaker and the fluid. If you need the mass of each separately, you can weigh the empty beaker first and then subtract that mass from the total.

If you place a dialysis bag filled with water into a beaker of water, there will be no significant change in the dialysis bag's contents, as both are isotonic. Since there is no concentration gradient for water to move across the semi-permeable membrane of the dialysis bag, osmosis will not occur. The bag will remain filled with water, and the surrounding water in the beaker will remain at the same level. However, if the dialysis bag contains solutes that are not present in the beaker, osmosis may occur, leading to a change in the bag's volume.
If an inhibitor of ATP regeneration were added to the beaker, the cell's ability to produce energy would be compromised, leading to a decrease in metabolic activity. This could result in a disruption of cellular processes, impacting the cell's viability and potentially causing cell death.
ill tell you if you tell me how you complete level 7
Yes. it is filled.
in beaker the substance that contains is largely transpearable ,but in pippette the substance tat contain is transparable only drop-wise
A half filled sub-shell is more stable than other partially filled shells. As an example use Chromium. It should by logic have the following: Sc = [Ar]4s23d1 Ti = [Ar]4s23d2 V = [Ar]4s23d3 Cr should in theory be Cr = [Ar]4s23d4 but it is not. Half filled shells are more stable so the configuration is Cr = [Ar]4s13d5 two half filled sub levels and then Manganese is Mn = [Ar]4s23d5 one full and one half filled level.
not sure... I am REALLY stuck too!
