Answer:
Every 15 degrees is an hour
Explanation:
What is the time difference in mean solar time between 30° N 75° W and 30° N 90° W?
Answer:
22.4L of one mole of any gas
or you can use PV=nRT
3.45*22.4=77.28
Explanation:
Answer:
2OH^-(aq) + Cu^2+(aq) -----> Cu(OH)2(s)
Explanation:
The net ionic equation usually shows the main ionic reaction that goes in the system. The other ions that do not participate in this net ionic equation are called spectator ions. Spectator ions do not participate in the main reaction occurring in the system.
The net ionic equation quite often result in the formation of a solid precipitate in the system such as Cu(OH)2.
The net ionic equation for this reaction is;
2OH^-(aq) + Cu^2+(aq) -----> Cu(OH)2(s)
At STP, copper (Cu) would be the only substance here that will exist in the solid state.
