When a reaction take place at low temperature than high temperature?
At low temperatures, reactions typically occur more slowly because the kinetic energy of the molecules is reduced, leading to fewer effective collisions between reactants. Additionally, some reactions may become thermodynamically favored at lower temperatures if they are exothermic. In contrast, at high temperatures, the increased kinetic energy can enhance reaction rates and allow for endothermic reactions to occur, but may also lead to side reactions or decomposition of reactants. Thus, temperature significantly influences both the rate and the direction of chemical reactions.
Do chemical reactions need gravity?
No, chemical reactions do not require gravity to occur. Chemical reactions involve the rearrangement of atoms and molecules, which can happen in the absence of gravity. Gravity may influence the rate or behavior of certain reactions on Earth, but it is not necessary for the reactions themselves.
What will most likely happen to a plant that does not receive any warter?
It would die. Some plants (cacti) may store enough water to carry it through a dry season. Some plants, in a drought, may try to generate seeds that will sprout again after the dry period is over.
Does chemical reactions need water?
Not all chemical reactions require water. While many reactions may occur in the presence of water, there are also reactions that take place in other solvents or under dry conditions. The presence of water can often act as a catalyst or a medium for facilitating certain reactions, but it is not a universal requirement for all chemical reactions.
How high is a landslide slope?
Landslide slopes vary depending on the type of material, angle of repose (angle material or debris natural forms when stacked or piled), and the conditions in which the landslide may occur.
What happens when both chemicals are alkaline?
Displacement may occur, or if both are made up in water, displacement reactions may occur between the ions of water and each chemical may occur

What are side effects from insulin?
The greatest short term risk of insulin is hypoglycemia.Allergic reactions and skin reactions also may occur.
Can goldenrod cause side effects?
Allergic reactions may occur in some people.
Increased temperature usually results in?
An increase in the kinetic energy of the molecules that a materiel is formed from. This can lead to a softening of the material or if enough energy is supplied the melting of the material. It can also cause chemical reactions which may alter the material. Both these processes occur in metamorphic rocks.
What are the potential skin reactions that can occur from exposure to iodine?
Potential skin reactions from exposure to iodine may include redness, irritation, itching, and in some cases, allergic reactions such as hives or rash.
Why cant you stop reactions from happening?
Chemical reactions may be slowed by lowering the temperature, but unlikely to stop all together.Nuclear reactions may be stopped by interposing an appropriate screen, such as a dense material, or at least one that is dense to radiation.
Do chemical reactions need gravity?
No, chemical reactions do not require gravity to occur. Chemical reactions involve the rearrangement of atoms and molecules, which can happen in the absence of gravity. Gravity may influence the rate or behavior of certain reactions on Earth, but it is not necessary for the reactions themselves.
What is the deterrence between cleverage and fracture?
Cleavage refers to the tendency of a material to break along specific planes of weakness, resulting in smooth, flat surfaces. In contrast, fracture describes a more general breaking or cracking of a material that may occur in various directions and may produce irregular surfaces. Essentially, cleavage is a specific type of fracture that occurs along predetermined lines, while fracture encompasses all forms of material failure.
What is omnipaque?
Omnipaque is a contrast material used for imaging studies. This means if your doctor orders certain kinds of tests where he may want to see vessels or structures more clearly, he may order the test "with contrast." At this point you will be injected with said material, which will light up on the image, highlighting certain areas of your body.
What is an another name for exothermic and for endothermic reactions?
it is a Many chemical reactions release energy in the form of heat, light, or sound. These are exothermic reactions. Exothermic reactions may occur spontaneously and result in higher randomness or entropy (ΔS > 0) of the system. They are denoted by a negative heat flow (heat is lost to the surroundings) and decrease in enthalpy (ΔH < 0). In the lab, exothermic reactions produce heat or may even be explosive. There are other chemical reactions that must absorb energy in order to proceed. These are endothermic reactions. Endothermic reactions cannot occur spontaneously. Work must be done in order to get these reactions to occur. When endothermic reactions absorb energy, a temperature drop is measured during the reaction. Endothermic reactions are characterized by positive heat flow (into the reaction) and an increase in enthalpy (+ΔH).
Where are hives most likely to appear after iv contrast injection?
Hives are most likely to appear in areas of the body where the contrast agent has circulated most rapidly, such as the face, neck, or chest. Additionally, hives may also appear on the arms or legs. It is important to report any skin reactions to your healthcare provider immediately.
