Answer:
The star is a special star
Explanation:
it is a binary star it is dominated by a luminous main sequence of star! it has a magnitude of -1.46. Sirius A's apparent bright ness can be attributed both to its inherited luminosity! 20 times that of thr sun anf its proximity. At just 8.7 Light years away sirius is the seventh closest star to earth.
Because if you have a liquid then you need a glass to keep it together and when it is a solid it is already together so you don't need to do anything
Answer:
0.0611M of HNO3
Explanation:
<em>The concentration of the NaOH solution must be 0.1198M</em>
<em />
The reaction of NaOH with HNO3 is:
NaOH + HNO3 → NaNO3 + H2O
<em>1 mole of NaOH reacts per mole of HNO3.</em>
That means the moles of NaOH used in the titration are equal to moles of HNO3.
<em>Moles HNO3:</em>
12.75mL = 0.01275L * (0.1198mol / L) = 0.0015274 moles NaOH = Moles HNO3.
In 25.00mL = 0.025L -The volume of the aliquot-:
0.00153 moles HNO3 / 0.025L =
<h3> 0.0611M of HNO3</h3>
