Answer:
ΔE = 150 J
Explanation:
From first law of thermodynamics, we know that;
ΔE = q + w
Where;
ΔE is change in internal energy
q is total amount of heat energy going in or coming out
w is total amount of work expended or received
From the question, the system receives 575 J of heat. Thus, q = +575 J
Also, we are told that the system delivered 425 J of work. Thus, w = -425 J since work was expended.
Thus;
ΔE = 575 + (-425)
ΔE = 575 - 425
ΔE = 150 J
The state of matter is liquid.
Answer:
When an atom of sodium and an atom of fluorine combine to form the salt, sodium fluoride, an ionic bond, is formed.
Explanation:
Answer:
saturated fats
Explanation:
bcoz it is solid at room temperature and does not have double bonds between carbons
0 degree Celsius is equal to 272 k
So to convert C to k we need to add 273
To convert K to C we need to subtract 273
