Answer:
See explanation
Explanation:
Recall that;
Speed = Distance/time
Distance = Speed * time
Speed = 200 km/h
Time = 4 hours
Distance = 200 km/h * 4 hours = 800 kilometres
Displacement has to do with distance covered in a specified direction, in this case, the direction is towards Zambales.
Hence, the displacement is 800 kilometres towards Zambales.

<h2>
<em><u>Empirical formula = C4H4S</u></em></h2>
Explanation:
The subscripts in a formula determine the ratio of the moles of each element in the compound. To convert this formula to the empirical formula, divide each subscript by 2. This is similar to reducing a fraction to its lowest denominator.
Answer: gaseous molecules are far apart
Explanation:
One of the states in which matter exists is gas. Gases are made of up molecules that are far apart, travelling randomly and rapidly within the containing vessel.
Hence, they are easy to compress whereby they occupy limited space as the gaseous molecules are closely packed in vessels like cylinders and transported to places where they may be needed.
<span>Water:
*can dissolve most substances
* contains dissolved minerals
*expands when it freezes</span>
No. water itself cannot be wet it makes things wet but because water molecules are already water it cannot make itself wet so in other words water makes things wet but its not exactly wet itself.
