I'm horrible at Chem plse help! Determine whether the reaction given below would be spontaneous or not. JUSTIFY your answer.
Mg2+ (aq) + Ag (s) → Ag+ (aq) + Mg (s)
Thank you
Answer:
This is a not a spontaneous reaction.
Explanation:
No, it would not be one because if you add the reactants the products would have to be the same (same types of atoms. number of atoms, and the arrangement of the atoms). In this case the reactants and the products are not equal.

hii what the procedures of making organic fertilizer and its precautions. can u answer it i kinda need it now
Answer:
Go through your kitchen waste. Vegetables and fruit peelings are the number one food remnants you should keep aside. ...
Add other organic materials to the compost. ...
Collect some garden waste. ...
Create the compost. ...
Apply the fertilizer.
Answer:
AbstractOrganic fertilizers are an essential source for plant nutrients and a soil conditioner in agriculture. Due to its sources and the composition of the organic inputs as well as the type, functionality and failures of the applied treatment process, the organic fertilizer may contain various amounts of infectious agents and toxic chemicals, especially the antibiotics that can be introduced to the subsequent food chain. A range of human and animal pathogens of bacterial, viral and parasitic origin have been the cause of food-borne epidemics due to unintended contamination from organic fertilizers. The use of antibiotics by humans and in animal feeds will also end up in the organic fertilizers. These antibiotics and other chemicals, depending on the sources of the organics, will enhance the likelihood of occurrence of resistant and multi-resistant strains of microorganisms in society and have been reported to cause ecotoxicological environmental effects and disruption of the ecological balance. Exposure of microorganisms to sublethal concentration of antibiotics in the organic products induces antibiotic resistance. WHO guidelines for the reuse of excreta and other organic matters identify the risk for the exposed groups to the reuse of the

Instructions: For this lab, use the Energy Skate Park Basics simulation and the lab report to record your information. You will submit your completed lab report.
Answer:
With the friction on, the minimum height I can place the skater so that he makes it all the way around the loop is 6 meters. This is about a meter higher than if the friction were turned off. The “lost” energy is going towards thermal energy. This means in real life that heat is being created due to the friction.

what do you do if you add a bit too much solvent when filling the volumetric flask to the mark
If excess solvent is added, discard the entire solution and begin the process of preparing the solution afresh.
It is common to prepare solutions using a standard volumetric flask. In this method, the required amount of solid or liquid is added to the volumetric flask and made up to mark with solvent.
Sometimes, it is possible to mistakenly exceed the mark as the solvent is added. In such cases, you must discard the entire solution and begin the process of preparing the solution afresh.

What could be a reason for the difference between the theoretical and experimental heats of reaction
Answer:
Theoretical value is the value a scientist expects from an equation, assuming perfect or near-perfect conditions. Experimental value, on the other hand, is what is actually measured from an experiment. Rarely (in fact never) are these numbers the same.
Take the area of a sheet of paper. I know that the area of a rectangle can be found by multiplying the lengths of both sides together. I can assume an 8.5x11 sheet, so I calculate exactly 93.5 square inches. This is my theoretical value. When I actually do the measurements on my paper, it turns out my paper has been slightly cut on one end, or I’m measuring with a shoddy ruler. Therefore, I might measure only 92.8 square inches. This is my experimental value. See thats it’s close, but not exact.
Expanding on this concept, quantum mechanics is so widely accepted in the scientific community because many theoretical values calculated by mathmaticians concurred with experimental values to many, many decimal places. These would be constants such as Plank’s Constant, energy levels of harmonic potentials, and energy levels of the hydrogen atom.
Explanation:
Theoretical result is based on information and mathematics. Trials or experiments are the foundation of experimental result. What ought to occur is theoretical probability. What actually occurs is experimental probability.
What is difference between theoretical and experimental result ?The definition of theoretical probability. It is not necessary to do the experiment and then analyze the findings for theoretical probability. The theoretical probability, however, represents what you anticipate will occur in an experimnet.
In experimental probability, information is gathered via repeated experimentation. In theoretical probability, data is gathered without doing the experiment by taking into account every possibility that has a chance of occurring.
Thus, difference between the theoretical and experimental heats of reaction the incomplete combustion may result in the formation of carbon and carbon monoxide instead of carbon dioxide and water.

How do catalysts generally affect chemical reactions? A They increase the temperature of the system. B They increase the surface area of the reactants. C They increase the activation energy by introducing enzymes. D They lower the activation energy by providing an alternate pathway.
Answer:
D
Explanation:
A catalyst is a substance that increases the rate of a chemical reaction by lowering the activation energy without itself being consumed by the reaction.
Activation energy is the minimum amount of energy required for a chemical reaction to proceed in the forward direction.
A catalyst increases the reaction rate by providing an alternative pathway or mechanism for the reaction

Answer:
B no. is the answer because
Explanation:
acids increase the hydrogen ion concentration, which provides more ionsan acid comes in contact with a metal, the acid steals free electrons away. That loosens the bonds holding metal atoms in place, so the metal dissolves. That's a chemical change, so the ability of acids to dissolve metals is a chemical propertyWhen a strong acid is neutralized by a strong base there are no excess hydrogen ions left in the solution. The solution is said to be neutral as it is neither acidic nor alkaline. The pH of such a solution is close to a value of 7; the exact pH value is dependent on the temperature of the solution.So this can probably be the the answer
