Pros: The rate at which modern medicine is advancing is astonishing. You can sit on your couch and watch TV and see commercials for new medications at an alarming pace — and these new medications have reduced our death rates for stroke, heart disease, and cancer. In fact, due to modern medicine, the death rate from heart disease has decreased by 60% since 1970! The death rate for HIV/AIDS has dropped more than 75% since 1995, when its was at its peak.
Cons: However, critics of modern medicine are quick to point out that there is a pill for everything . Yes we are quick to create more drugs, and yes, we are living longer due to said drugs but are we living better?
Medicine has evolved, and we now have surgeons who are able to perform surgeries robotically. But critics point out that medicine has evolved to the point that we are treating disease instead of preventing it .
H2O is the missing reactant.
Just a caveat: this equation isn’t balanced.
The answer is negative, since neutron is neutral and Protons have Positive.
Answer:
Melting is an example of an endothermic change.
Explanation:
This is because the system absorbs (heat) energy from the surroundings to increase its temperature.
Answer:
This is an exothermic reaction
q = 563 kJ
Explanation:
Step 1: The balanced thermochemical equation
H2CO(g) + O2(g) → CO2(g) + H2O(l) ΔH = -563 kJ
This is a combustion, this means there will be released heat. This means it's an exothermic reaction.
The energy involved, will be released (that's why ΔH is negative)
q has the same value as ΔH (but positive)
q = 563 kJ
