What compound do all living things need for dissolving of chemical substances?
Water
What is The process of dissolving a powdered drink in a glass of water demonstrates the principle of?
The process of dissolving a powdered drink in a glass of water demonstrates the principle of solubility, which refers to the ability of a substance (the powder) to mix uniformly with a solvent (the water) to form a solution. When the powder is added to water, the solvent molecules interact with the solute particles, breaking them apart and evenly distributing them throughout the liquid. This process illustrates how different substances interact at the molecular level, highlighting concepts such as concentration and the factors that affect dissolution, such as temperature and agitation.
What is the mole of the concentration of KBr in a solution prepared by dissolving 2.21g of KBr in 897g of water?
The answer is 0,0207 mol.
Dissolves in water chemical change or physical?
Dissolving in water is a physical change because the chemical composition of the substance remains the same. The particles of the substance are dispersed in the water but do not undergo a chemical reaction to form new substances.
Suger cube dissolves in water is it chemical or physical change?
The dissolving of a sugar cube in water is a physical change, not a chemical change. This is because the sugar molecules are still present in the water; they have not undergone a chemical reaction to form new substances.
Does dissolving always involve water?
No, dissolving does not always involve water. Dissolving is a process where a solute mixes with a solvent to form a homogeneous mixture. While water is a common solvent that is often used for dissolving substances, other solvents such as alcohol or acetone can also be used depending on the substances being dissolved.
What is the relative concentration of dissolved substances in water?
The relative concentration of dissolved substances in water is typically measured as parts per million (ppm) or milligrams per liter (mg/L). This measurement indicates the amount of a particular substance that is dissolved in a unit volume of water. High concentrations of dissolved substances can affect water quality and aquatic life.
How does water dissolving so many substances be essential for life?
because if you dont have water you will die
What compound do all living things need for dissolving of chemical substances?
Water
How did those substances go into the water outside the dialysis?
The substance moved into the water through osmosis. The concentration of the substances inside the dialysis bag was higher than in the water and membrane was permeable to the substances. As such, they moved from a high to a low concentration along a concentration gradient.
What kinds of substanances dissolve in water?
Substances that dissolve in water are typically polar or ionic compounds like salts (such as sodium chloride), sugars (like glucose), and some gases (like oxygen and carbon dioxide). Nonpolar substances, such as oils and fats, do not dissolve well in water.

water

Why does the fact that water is a polar molecule contribute to the variety of substances dissolving in water?
because about a cajillion things will be attracted to either end of the poles
Water is very effective at dissolving other polar substances because of its what?
Because it is hydrophilic...."water-loving." Examples of these are sugars, salts and ions. :)
