What else can I help you with?
What are 3 observations that would tell you that new products had been made in a reaction?
Change in color or appearance of the mixture. Evolution of gas or formation of bubbles. Generation of heat or cooling of the reaction mixture.
Which is the best solution of data center cooling?
The best solution of data center cooling would best be answered by a professional as there are many things to factor when looking into data center cooling. If money is an issue then the energy efficient model would be the best solution. Cisco is a provider of data center cooling and could better access one's needs.
Which reaction would produce a solution that conducts electricity extremely well?
electrolyte.electrolyteIn solution
What color would you see if iodine solution is added to starch?
The color change that occurs when iodine solution is added to starch is a dark blue or purple color. This reaction is commonly used to test for the presence of starch in a solution.
Why dissolving Ammonium nitrate(NH4NO3) in water is an endothermic although the temperature of the solution decreases?
The energy needed to support the endothermic reaction is supplied by the solution; thus the solution temperaturedecreases.If the reaction were exothermic, the solution temperature would increase.
How would the appearance of the solution change for each kinetic trial if the Na2S2O3 solution were omitted from the experiment?
If the Na2S2O3 solution were omitted, the appearance of the solution would not change significantly for each kinetic trial. Na2S2O3 is a reagent that acts as a reducing agent and is not directly involved in the appearance of the reaction solution. Its absence would likely affect the reaction rate rather than the visual appearance of the solution.
Would the pH of the solution be lower before or after the enzymatic reaction?
The pH of the solution could change during an enzymatic reaction. It could either increase or decrease depending on the specific reaction and the components involved.
What would you observe if astatine solution is added to sodium bromide solution?
When astatine solution is added to sodium bromide solution, a reaction is likely to occur where astatine displaces bromine to form astatide ions. This would result in the formation of astatide ions in solution and sodium bromide precipitating out as a solid, which can be observed as a color change or cloudy appearance in the solution.
What are 3 observations that would tell you that new products had been made in a reaction?
Change in color or appearance of the mixture. Evolution of gas or formation of bubbles. Generation of heat or cooling of the reaction mixture.
When the reaction with potassium had finished what would happen if you added universal indicator solution to the water?
If you add universal indicator solution to the water after the reaction with potassium, the indicator will change color depending on the pH of the solution. Potassium reacts with water to form potassium hydroxide, which is a strong base. The solution will likely turn purple or blue indicating a high pH.

Is mixing acid with a base a chemical change?
Adding a base to an acid or vice versa in changing the chemical properties of that solution. In both cases you are neuralizing the solution. There might be a physical change as well, but it would depend on what chemicals where mixing. But this reaction will definitely have a chemical change.
What is the reactions of acid and base?
When an acid reacts with a base, they neutralize each other to form water and a salt. This is known as a neutralization reaction. The pH of the resulting solution will be closer to 7, indicating a neutral solution.
What color would you see if iodine solution is added to starch?
The color change that occurs when iodine solution is added to starch is a dark blue or purple color. This reaction is commonly used to test for the presence of starch in a solution.
Why would you add sulfuric acid to a mixture of oxalic acid and sodium oxalate?
This is an example of a buffer solution. if the sulfuric acid were added to a plain glass of water, it would have a massive change in pH. However, the buffer action of the oxalate-oxalic acid solution will decrease this change to something very minor (demonstrably to only hundredths or thousands, if the solution is made well, of the change it would have on pure water).
What do you call something that's concentrated?
a really concentrated solution would undergo a reaction quiet dramatically. the colour of the solution would be darker
