What are 2 ways that convection currents in the oceans distribute the sun's energy?

Answer:

When air in contact with the ocean is at a different temperature than the sea surface, heat transfer by conduction takes place. The ocean also absorbs and stores energy from the sun, and when precipitation falls, it releases heat energy into the atmosphere.

Hope it helps:)

Answer:

18,1 mL of a 0,304M HCl solution.

Explanation:

The neutralization reaction of Ba(OH)₂ with HCl is:

2 HCl + Ba(OH)₂ → BaCl₂ + 2 H₂O

The moles of 17,1 mL≡0,0171L of a 0,161M Ba(OH)₂ solution are:

$0,0171L*\frac{0,161moles}{L}$ = 2,7531x10⁻³moles of Ba(OH)₂

By the neutralization reaction you can see that 2 moles of HCl reacts with 1 mole of Ba(OH)₂. For a complete reaction of 2,7531x10⁻³moles of Ba(OH)₂ you need:

$2,7531x10^{-3}molBa(OH)_{2}*\frac{2molHCl}{1molBa(OH)_{2}}$ = 5,5062x10⁻³moles of HCl.

The volume of a 0,304M HCl solution for a complete neutralization is:

$5,5062x10^{-3}molHCl*\frac{1L}{0,304mol}$ = 0,0181L≡18,1mL

I hope it helps!

What is the concentration of a solution containing 0.32 moles of NaCl in 3.4 liters?

dsp73

Get the molarity we need to divide the number of moles of NaCl by the volume of the solution. So, 0.32 moles NaCl divided by 3.4 L, and that gives 0.094 M NaCl.

Hey there!

3d band can hold as many as 10 electrons, while 4s can bear as many as two electrons.

The maximum number of electrons for this composite band should be 12 electrons.

Hope that helps!
