Cu + 2 AgNO₃ = 2 Ag + Cu(NO₃)₂
mole ratio:
1 mole Cu --------------> 2 moles Ag
? mole Cu --------------> 3.50 moles Ag
moles Cu = 3.50 x 1 / 2
moles Cu = 3.50 / 2
<span>= </span><span>1.75 moles</span>
We use soil, water, and air everyday
Answer:
Explanation:
Deepwater currents are formed, when the water becomes denser, surface water is cool. and movement of water below the surface.
- Currents are caused by differences in <u>density, temperature, and salinity.</u>
- The water along the surface forms wind currents, and deep currents are caused by differences in temperature and salinity.
Hope this helps you!
Good Luck with your Assignment!

To determine the amount of heat released upon complete combustion of 1 mol of methane, we simply multiply the heat of combustion of methane with the mass of methane. In this case, first, we need the molar mass of methane to convert the moles of methane given to grams of methane. We then have the following equation:
1 mol CH₄ x 16.0425 g/ mol CH₄ x 50.1 kJ/ g CH₄ = 803.73 kJ
Thus, the heat generated upon complete combustion of 1 mol of CH₄ is 803.73 kJ
Answer:
To be stable an atom will gain, lose, or share electrons to complete the outer most energy level (electron shell). Octet Rule because levels 2 and 3 need 8 electrons to be stable.
