When are the water molecules H and OH reattached?
Water molecules, specifically the hydrogen (H) and hydroxyl (OH) components, are reattached during the process of hydration in various chemical reactions, particularly in biological systems. This occurs when water is formed as a product of a reaction, such as during cellular respiration or photosynthesis. Additionally, in the context of chemical synthesis, reattachment can happen during hydrolysis reactions, where water molecules break chemical bonds and subsequently reform.
What is the arrangement of molecules of matter?
The molecules in a solid are bonded together permanently. Liquid molecules, on the other hand, also have bonded molecules but they continuously break and reform with other molecules. Gas molecules are not bonded.
Which bonds are affected during blow drying and setting?
Hydrogen bonds in the hair are temporarily broken by heat during blow drying and setting. When the hair cools down, the hydrogen bonds reform in the new shape, helping to set the hair in the desired style.
What helps weaken the bonds so that energy can be released and then later help reform them?
Chemical reactions weaken bonds to release energy, such as breaking bonds in reactant molecules to form products. Later, these bonds can reform through reverse reactions or other processes like condensation. Energy is used and released in these transformations.
If you heat an element to 1000000 degrees Fahrenheit would the element change when it cooled?
Depends on the element, for example Hydrogen gas would likely combust: 2 H2(g) + O2(g) → 2 H2O(l) and hence would have changed. Metals may melt or begin to evaporate at those temperatures but would likely condense to reform the elemental metal. Some metals would change upon heating to such high extent due to oxidation or other chemical reactions with the environment.
Do hydrogen bonds break and reform in liquid?
Yes, hydrogen bonds can break and reform in liquid water. As water molecules move and interact with each other, hydrogen bonds continuously form and break due to the attraction between the positively charged hydrogen atoms and the negatively charged oxygen atoms. This dynamic process is essential for the unique properties of water such as high surface tension and specific heat capacity.
Do hydrogen bonds in pure water break and reform?
Yes, hydrogen bonds in pure water break and reform constantly due to the constant movement of water molecules. This dynamic process is essential for the unique properties of water, such as its high surface tension and specific heat capacity.
What does acetic acid dissociate into?
Acetic acid dissociates into hydrogen ions (H+) and acetate ions (CH3COO-) in aqueous solutions. This process is reversible, with the ability to reform acetic acid molecules.
What attractive forces must be overcome to dissolve sugar in water?
dG = dH -TdS Gibbs free energy has to be negative, ie. Temperature*Entropy has to be greater than enthalpy. First the crystal lattice has to be broken which costs energy, but then energy is gained when water and sugar interacts.
What happens when hydrogen iodide breaks down?
When hydrogen iodide breaks down, it forms hydrogen gas and iodine vapor. The reaction is reversible, meaning that hydrogen iodide can reform if hydrogen gas and iodine are combined.
What was the middle way between Orthodox and Reform Judaism?
In between the Orthodox and Reform Jewish communities is the Conservative movement, although, the Conservative movement is closer to Orthodox than Reform.
What factor will most likely improve economic growth in weak rule-of-law countries. captilism or political reform?
Political Reform
Which group most likely to join reform movements?
The middle class
What happens to H-Bonds in water when it solidifies?
When water solidifies (freezes), its molecules assume a crystalline structure. The structure is held together by hydrogen bonds. In the liquid they are broken and reform as "clumps" of water molecules move around- in the solid the water molecules are relatively static. the structure is "open" which is why ice is less dense than water. Water is unusual in this, generally substances are more dense in the solid form than when they are molten.

Does NAD serve as an oxygen acceptor a coenzyme a waste product an end product or an acid acceptor in cell respiration?
NAD is a coenzyme.Its role is as a hydrogen acceptor when it is involved in the oxidation of glucose (cell respiration). Is is written as NAD+, and after accepting hydrogen it becomes the reduced form, NADH.NADH in turn acts as a hydrogen donor when it becomes oxidized to reform NAD+.
How do hydrogen bonds involve low volatility?
hydrogen bonding is the strongest intermolecular force between molecules. It has low volatility which means that it has a low vapor pressure and therefore takes more energy to evaporate the substance. This makes sense because you need more energy to break up the bond of stronger bonds and to evaporate them.
