Answer:
-27.2 kJ
Explanation:
We can use the heat-transfer formula. Recall that:
Where <em>m</em> is the mass, <em>C</em> is the substance's specific heat, and Δ<em>T</em> is the change in temperature.
Hence substitute:
Therefore, the cooling of the water <em>released</em> about 27.2 kJ of heat.
WHat? May you please rephrase your question? I think you meant in an organic compound? The answer to that would be CARBON.
U need to do it in cronological order
Answer:
63.5°c
Explanation:
almost postive this is right
Answer:
as no. of protons is equals to the no. of electrons so, it is a neutral atom.
but, as Atomic No. = Mass No. - No. of neutrons
Atomic No. = No. of protons = 18
so, Mass No. = Atomic No. + No. of Neutrons= 18 + 20 = 38
so, correct option is C.
