Answer:

I think it's the last one.

Explanation:

Because gravity is what makes our planets stay still and stops our planets from dropping and as they orbit around the sun that's what keeps the moon from bumping into earth. I hope this helps and makes sense.

What is the minimum volume of 5.50 M HCl necessary to neutralize completely the hydroxide in 718.0 mL of 0.183 M NaOH

Deffense [45]

The volume of HCl required is 23.89 mL

Calculation of volume:

The reaction:

$HCl + NaOH \rightarrow NaCl + H_2O$

As HCl and NaOH react in 1 : 1 ratio.

Volume of NaOH= 718 mL

Concentration= 0.183M

Volume of HCl= ?

Concentration= 5.50M

Using the dilution formula:

$M_1\times V_1(NaOH)= M_2\times V_2(HCl)$

$0.183\times 718= 5.50 \times V_2\\V_2=\frac{131.394}{5.50} \\V_2 = 23.89 \,mL$

Therefore,

Volume of HCl required will be 23.89 mL.
