How do sociologists talk about how the individual is related to the larger society?
Viktor [21]

Answer:

Sociologist view that an individual is a reflection of a society to which he or she have belonged.

Explanation:

It is not an individual or a society, but both of them together allows us to reveal the fundamentals of human existence. The extreme view of the person or society has been discarded for quite some time. The concept of society indicates a reciprocal giving-and-take by the individuals involved in the form of mutual corporations, interaction, or the more subtle types of social interaction such as letter writing, festival greeting, sending and accepting presents, telephone communication, e-mailing, internet chatting, and public relations engagement.

Please help me Solve this *I DONT WANT THE ANSWER* Just give me a good explanation...
timurjin [86]

Answer:

C

Explanation:

'Ordered Arrangement' basically means that it is a solid at room temperature. Room temperature is approximately 15-20C so we are looking for melting and boiling points that are above room temperature so it hasn't/can't melt or boil at room temperature and would therefore be solid. Option C is the only one where both points are temperatures above room temperature therefore option C is the only one where the substance would be in an 'ordered arrangement' at room temperature.

Hope this helped!

The rate constant for the decomposition reaction of H2O2 is 3.66 × 10−3 s−1 at a particular temperature. What is the concentrati
Pepsi [2]

Answer:  3.72 M

Explanation:

Expression for rate law for first order kinetics is given by:

t=\frac{2.303}{k}\log\frac{a}{a-x}

where,

k = rate constant = 3.66\times 10^{-3}s^{-1}

t = age of sample = 15.0 minutes

a = let initial amount of the reactant  = 10.0 M

a - x = amount left after decay process = ?

15.0\times 60s=\frac{2.303}{3.66\times 10^{-3}}\log\frac{10.0}{(a-x)}

\log\frac{100}{(a-x)}=1.43

\frac{100}{(a-x)}=26.9

(a-x)=3.72M

The concentration of H_2O_2 in a solution after 15.0 minutes have passed is 3.72 M
