Answer:
C) Liquids and gases
Explanation:
<em>The correct answer would be liquids and gases.</em>
<u>The molecules of liquids and gases move randomly when held in a container. The random movement causes a collision between the molecules of the liquids/gases and between the walls of the container, creating pressure in the process. </u>This is unlike the molecules of solids that vibrate about fixed positions.
Hence, the correct option is C.
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.
Answer:
a. NaNO3 and CuCl2
Explanation:
The other 3 react as follows:
Ba(OH)2 and HNO3 ---> BaNO3 + H2O
CaCl2 + Na3PO4 ---> CaPO4 + NaCl
AgNO3 + HCl ---> AgCl + HNO3
Answer:
The answer is
<h2>0.15 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass of object = 13.57 g
volume = 89.6 mL
The density is
We have the final answer as
<h3>0.15 g/mL</h3>
