Give three examples of herbal medicines that can easily be purchased at a local supermarket or pharmacy with no prescription. Provide the name of the medicine, what is it made of, and what is the reason why people take them. What are your thoughts about these three herbal medicines? Do you believe they work? Conclusion There are several herbal medicines that can easily be purchased […]

Why is an atom said to be electrically neutral? The smallest piece of stuff that can be destroyed without releasing electrically charged particles is believed to be an atom. Because the three subatomic particles that make up an atom are known to exist, an atom is said to be electrically neutral. These subatomic particles are neutrons, electrons, and protons (He et al., 2019). The structure […]

5.You have been invited to assemble a task force to design a medication assistance program. You need to submit a proposal, regarding who you would invite, to the CEO. Consider the perspectives of prescribers, discharge planners, financial navigators, patients, suppliers, book keepers and subsidizers. If you were to seek the input of 5-7 stakeholders, who would you invite to the planning table, and why? Consider […]

The equation below shows the reaction of sodium with water. In an experiment 0.85g of sodium were reacted with a large volume of water. 2Na+2H2O —>  2NaOH + H2Find the number of moles of sodium reacting with water in this experiment. 

How do I know how a change in acetic acid involved in a buffer solution affects the order of the reactant [H+]. I got rate=k[H2O2][I-] and the order for [H=] is 0. However, would this affect the order of H+ if I used a different concentration of acetic acid?
