Answer:
a. NaNO3 and CuCl2
Explanation:
The other 3 react as follows:
Ba(OH)2 and HNO3 ---> BaNO3 + H2O
CaCl2 + Na3PO4 ---> CaPO4 + NaCl
AgNO3 + HCl ---> AgCl + HNO3
Answer:
just see it it will help trust me its my school work
Explanation:
Moles of Helium = 39.1 moles
ΔT = (38.08 – 0.08) ֯C = 38.00 ֯C
Q = nC ΔT = 39.1 * 20.8 J/ ֯C mol * 38.00 ֯C = 30904.64 J
W
= P * <span>ΔV = 1atm * (948 - 876) L =
122 atmL</span>
1atmL = 101.325 J
W = 122 * 101.325 J = 12361.65 J
ΔE = q + W = (30904.64 + 12361.65) J = 43266.29 J
Answer is 43266.29 J
Answer:
Fluorescent tubes do not get as hot as incandescent bulbs because they emit most of their energy as light. This means that they use energy very efficiently. One 18-watt fluorescent tube provides the same amount of light as a 75-watt incandescent bulb, and the fluorescent tube lasts ten times longer.

Explanation:
Magnetic materials are always made of metal, but not all metals are magnetic. Iron is magnetic, so any metal with iron in it will be attracted to a magnet. Steel contains iron, so a steel paperclip will be attracted to a magnet too. Most other metals, for example aluminium, copper and gold, are NOT magnetic.
