Answer:
-41. 47
Explanation:
m = q / Cp x T
m = Mass
q = Energy (or joules)
Cp = Heat Capacity
T = Change in Temperature
Water's heat capacity is always 4.18.
This is the formula you'll need for change in temperature:
Final - Initial
So, 33 - 78 = -45
m = 7800 / 4.18 x -45
= -41.47
The answer is B. The chlorine has 7 electrons at the outer shell. So it will gain one electron to become stable when forms a chloride ion. And the gained electron will stay at the outer shell. So the radius becomes larger.
Answer:
studying chemicals containing carbon.
Explanation:
Pure chemistry can be regarded as
branch of science that's based on conduction of basic research so that
personal knowledge can be acquired. It can be reffered to as theoretical branch of chemistry, not applied branch. It comes with curiosity about something, how and why it happens. For instance, studying chemicals containing carbon is to gain knowledge there's no applied chemistry here
