What else can I help you with?
Give examples of where reaction times are important in schools?
well when a kid brings a gun to school and starts shooting your reaction time will have an effect on your survival chances
What effect dose temperature have on reaction rate?
It depends on the original temperature, but the rule of thumb is that near normal room temperature, raising the temperature by ten degrees will roughly double the reaction rate.
What is the effect of anaesthesia on the respiratory centers?
Under deep anesthesia the respiratory reaction to CO2 disappears but in response to reflex stimulation remains the same as under moderate anesthesia .
Effect of pH on a molecule?
It depends on the molecule of course. some molecules have a soft hydroxide group, that is a OH sticking out somewhere that isn't all that closely held. Increasing the pH in the environment of such a molecule can result in a free hydrogen ion latching onto the hydroxide group and forming a water molecule - in effect removing the hydroxide group from the molecule. This is a process known as dehydration - the removal of water. Dehydration is both an important and detrimental process in making Urea, a nitrogen rich fertilizer. Some slightly complex molecules we 'bend into a new shape' in the presence/absence of hydrogen ion. The electro-presence of hydrogen ions affecting the arrangement of certain hydrogen bonds with in the molecule. This is the case with some pH indicators. This bending and refolding can occur countless times as there is no net change to the molecule.
What is a hypothesis for fourth grade science project on making a lava lamp?
A hypothesis for a fourth-grade science project on making a lava lamp could be: "If I mix oil and water with food coloring and add an effervescent tablet, then the colored water will rise and fall in the oil, creating a lava lamp effect." This hypothesis suggests that the differences in density and the reaction of the tablet will cause the desired visual effect.
What is the effect of a Cannizzaro reaction?
The effect of a Cannizzaro reaction involves the attack of hydroxide. This results in an attack on another molecule, which results in the exchange of a proton.
What is the balanced equation for zinc hydroxide react with excess sodium hydroxide?
There is no reaction between zinc hydroxide and sodium hydroxide.
What happens when you mix Ammonium Nitrate with Water?
When ammonium nitrate is mixed with water, it dissolves in the water and causes a significant cooling effect, making the solution cold to the touch. This is an endothermic reaction, where heat is absorbed from the surroundings causing the decrease in temperature. Extreme caution should be taken as large amounts of ammonium nitrate mixed with water can lead to a highly exothermic reaction, resulting in an explosion.
What evidence of a chemical reaction in the appearance of dark spots on an old mirror?
The dark spots on a mirror are the effect of the decomposition of silver nitrate (AgNO3) to silver (Ag).
What is the chemical reaction of phenolphthalein and sodium hydroxide?
Phenolphthalein reacts with sodium hydroxide to form a pink color, indicating the presence of a base. The chemical reaction involves the deprotonation of phenolphthalein by hydroxide ions to form an ionized molecule with a pink hue.
How is sodium hydroxide and chlorine used to make bleach?
Bleach consists of chlorine gas dissolved in an alkali-solution, such as sodium hydroxide (NaOH). When chlorine is dissolved in an alkalic solution, hypochlorite ions (OCl-) are formed during an autoredox reaction. Chlorine reacts with sodium hydroxide to sodium hypochlorite (NaOCl). This is a good disinfectant with a stable effect.
Reaction between methyl salicylate and sodium hydroxide?
When methyl salicylate (oil of wintergreen) reacts with sodium hydroxide (NaOH), it undergoes saponification to form sodium salicylate and methanol. This reaction is a base-catalyzed ester hydrolysis reaction that converts the ester functional group of methyl salicylate into a carboxylate salt.
What reaction can be performed to tell the difference between sodium chloride and sodium hydroxide?
A litmus test is one way of comparing. Sodium Chloride is a neutral salt and so would have no effect on litmus. Sodium Hydroxide is a base, and would turn litmus blue.
What is effect of alkali on Aluminium?
Alkali, such as sodium hydroxide or potassium hydroxide, reacts with aluminum to produce hydrogen gas and soluble aluminum hydroxides. This reaction occurs because alkali can break down the protective oxide layer on aluminum, allowing further reaction with the metal. The reaction is exothermic and can be vigorous, leading to the release of flammable hydrogen gas. As a result, aluminum is generally not stable in strongly alkaline environments.
Would borax react with calcium nitrate?
yes there would be a reaction: would create heat & possible poisnous fumes. if left in right conditions a smoldering effect could lead to fire & is corrisive to persons skin & such.
What effect does oxygen do on limewater?
Oxygen does not have a direct effect on limewater. Limewater is a solution of calcium hydroxide, and when exposed to carbon dioxide, it forms calcium carbonate, turning the limewater milky. Oxygen does not directly interact with the limewater in this chemical reaction.
What happens when you mix distilled water and ammonium nitrade?
When you mix distilled water and ammonium nitrate, the ammonium nitrate dissolves in the water, leading to an endothermic reaction that can cause the mixture to become cold. This solution is commonly used as a cold pack to create a cooling effect. However, it is important to handle ammonium nitrate with caution as it can be hazardous if not used properly.
