When encountering another vessel in darkness, the visible white, red and green lights indicate you are approaching a powerboat head-on.
In this case neither vessels has the right of way. Both boat operators must take early action to stay out of the way for other vessels. The operators must reduce their speed and steer to starboard.
<h2>Further Explanation</h2>
The visible white, red and green lights are all navigation lights with different purposes. However, the four common navigational lights are sidelights, sternlight, Masthead light and all-round white light.
Sidelights are also referred to as combination lights. It is the combination of red and green light and visible to another vessel that approaching head on or from the side. The green light is the boat starboard (right hand side) and the red light is the port side (left) of a vessel.
The sternlight is the white light seen from behind the vessel.
The masthead light is a white light. The white light shines forward to all sides of the vessels. It is on all power driven vessels.
All-round white light is a white light used to combine sternlight and masthead light to form a single white light so that it can boldly be seen by other vessels.

Answer:
0.00369 moles of HCl react with carbonate.
Explanation:
Number of moles of HCl present initially = 
moles = 0.00600 moles
Neutralization reaction (back titration): 
According to above equation, 1 mol of NaOH reacts with 1 mol of 1 mol of HCl.
So, excess number of moles of HCl present = number of NaOH added for back titration = 
moles = 0.00231 moles
So, mole of HCl reacts with carbonate = (Number of moles of HCl present initially) - (excess number of moles of HCl present) = (0.00600 - 0.00231) moles = 0.00369 moles
Hence, 0.00369 moles of HCl react with carbonate.
