Answer:
856,68 J/gram
Explanation:
We know that the variaton of temperature of 1K is equal to 1°C
so if the ΔT is 3.55°C, it is 3.55K.
so
403 J - 1 K
x - 3.55K
X= 403 * 3.55 = 1430,65 J
1.670 g - 1430,65 J
1 g - y
y = 
= 856,68 J
Answer:
The correct answer is electrons.
Explanation:
The electrons refer to the negatively charged constituents, which are arranged in the orbits around the nucleus of an atom. It determines all the chemical and physical characteristics of an atom except the radioactivity and mass. It is a stable subatomic particle witnessed in all the atoms and functioning as the chief carrier of electricity in solids.
Answer:
2K + Br2 --> 2KBr is the answer
