Why does sugar take less time to dissolve in hot water?
Heat invariably speeds up reactions. Heat is actually kinetic energy at the molecular level, so in this case, it dissolves quicker because water molecules are colliding more (and with more force) with the sugar cube.
Is koolaid a mechanical mixture?
No, Kool-Aid is a solution, not a mechanical mixture. A mechanical mixture is a combination of different substances that are physically mixed together but keep their individual properties. In the case of Kool-Aid, the powder dissolves completely in the water, creating a homogeneous solution.
Why is oxygen not soluble?
Oxygen is actually soluble in water to some extent, but it is not as soluble as other gases such as carbon dioxide or nitrogen. The low solubility of oxygen in water is due to its nonpolar nature and the weak interaction between oxygen molecules and water molecules.
What is the substance that repels water?
Hydrophobic repels water.
Is a solution a physical or chemical change?
A solution is not a change; a solution is represented by a solute dissolved in a solvent; but dissolving (without chemical reaction) is a physical process.
When salt is dissolved in water it actually breaks down into two different substances. Is salt composed of atoms of molecules?
salt is composed of Atoms. not Molecules. i know i am answering my own question but i found the answer.
What is the process called by which matter is actually changed into new substances?
The process by which matter is changed into new substances is called a chemical reaction. During a chemical reaction, atoms are rearranged to form different molecules with new properties compared to the original substances.
Which property of water explains why seawater contains over 20 different elements?
The property of water that explains why seawater contains over 20 different elements is its ability to dissolve and transport substances. Water is a universal solvent, capable of dissolving a wide variety of ions and molecules. As seawater comes into contact with rocks and minerals in the Earth's crust, it dissolves and carries a diverse range of elements, contributing to the complex composition of seawater.
Is sugar a substance?
Yes, or actually it's several substances. There are many different kinds of sugar.
Molecules of two solid substances actually collide with each other to transfer energy in this method of heat transfer.?
Conduction is the method of heat transfer where molecules of two solid substances collide with each other to transfer energy. This process occurs through direct contact between the particles.
Why does sugar take less time to dissolve in hot water?
Heat invariably speeds up reactions. Heat is actually kinetic energy at the molecular level, so in this case, it dissolves quicker because water molecules are colliding more (and with more force) with the sugar cube.
Why do large molecules need to be broken down into smaller molecules in the digestive system?
When large molecules are broken down they actually turn into a different substance. Proteins break down into amino acids. Lipids break down into fatty acids. Carbohydrates break down into simple sugars. And those are just a few of them. Large molecules need to break down so that they can change into other substances so they can dissolve or help the body another way.
Is koolaid a mechanical mixture?
No, Kool-Aid is a solution, not a mechanical mixture. A mechanical mixture is a combination of different substances that are physically mixed together but keep their individual properties. In the case of Kool-Aid, the powder dissolves completely in the water, creating a homogeneous solution.
Can a grasshopper decompose?
No, actually the Queef and while theyre queefing, the plant dissolves.
Is water called the universal solute because it dissolves many substances?
The substances that are important to living things and can be dissolved by water, a.k.a. "universal solvent," are easily soluble. The substances that are important to living things are most likely usually positive rather than negative.
Is octanol soluble with hexane?
Octane is a non polar compound. Sodium hydroxide is an ionic solvent. So octane is not soluble in NaOH and they together involve in no reactions.
Why do you found it useful to have two units for the amount of substance the kilograms and the mole?
Actually, the kilogram and the mole measure two quite different things. The kilogram is a unit of mass. The mole is a unit of amount of substance, in the sense of the amount of atoms or molecules (in multiples of Avogadro's number). The same amount of kilograms can have varying amounts of moles, for different substances.
