Answer:
iron, graphite,NaCl solution etc are some examples of good conductor of electricity
Answer:
Endothermic
Explanation:
Because Endothermic is cold and exothermic is hot and if you are using an ice pack it would be Endothermic and if you were using something that was hot it would be exothermic
Answer:A scientist can do a power point presentation to best communicate data to other scientists.
Explanation:
Answer: Copper (I)
Explanation:
The number of protons in an atom directly correlates to the identity of the atom, so this ion is copper. The charge relates to the balance of protons and electrons, so this ion has one more proton than it does electrons, making our final answer Copper (I). (Make sure to state the charge of transition elements! In this case our charge is 1+, so we'll put a (I) after the name!)
<span>C = 4.18
delta T = 24.25 - 23.16 = 1.09
mol = 0.070L * 0.185M = 0.01295
m = d*v = 1.00*(0.070+0.070) = 0.14g
So, delta H = q/mol HCl = [mC(deltaT)]/mol HCl = (0.14*4.18*1.09)/(0.01295) = 49.3 kJ</span>
