What’s drugs produce a calming effect by slowing brain activity and reducing the heart rate

Anti-anxiety

Explanation:

Anti-anxiety drugs, also known as anxiolytics, are drugs that produce a calming effect by slowing brain activity and reducing the heart rate of a person. These drugs are used in order to inhibit anxiety and the symptoms that accompany it, such as tachycardia and palpitations. Although some recreational drugs may induce anxiolysis, in general they tend to be anxiogenic.

what are the two models

explanation:

a. the law of proportion states the combination of 2 atoms in a specific ratio to produce multiple compounds such as the given statement of question ‘1st compound contains 88.8 % cu ’ indicates 88.8 g of cu is present along with 11.2 g oxygen in 100 g of compound whereas the statement ‘2st compound contains 79.9 % cu ’ indicates 79.9 g of cu is present along with 20.1 g oxygen in 100 g of compound

1st compound contains 88.8 g cu

for cu

m = 63 g /mol

atomic % = 88.8 /63 = 1.42

for o

m = 16 g /mol

atomic % = 11.2 /16 = 0.7

b. the emperical formula of 1st compound is

cu1.4o0.7
