Answer: gases
(has bubbles in the rock)
Answer:
The distance covered when speedwalking for 10 minutes based on the 8 meters trial (assuming a speed of 1 m/s) is 600 meters.
Explanation:
The speed of a body is the distance it covers per unit time when it travels. Its formula is given as; speed = distance/time. Its unit is meters per second as distance is measured in meters while time is measured in seconds.
From this formula, the distance covered by a body travelling with a given speed over a specific time can be determined. Distance = speed × time. This formula applies generally in all cases given the speed of the body and the time it travels.
Speed walking means walking as fast as possible without jogging or running. In this experiment, the speed over the 8 meters trial is not given. However, some assumptions can be made.
Assuming the speed while speedwalking is 1 meters per second; time taken = 10 mins or 10 × 60 seconds = 600 seconds. Distance covered = 1 m/s × 600 s = 600 m
Therefore, the distance covered when speedwalking for 10 minutes based on the 8 meters trial (assuming a speed of 1 m/s) is 600 meters.
The correct sentence is this:
THE VAPOUR PRESSURE OF ACETONE IS SMALLER THAT THAT OF WATER AT THE SAME TEMPERATURE.
Acetone will evaporate more quickly that water when exposed, this is because, its vapour pressure is smaller than that of water. The vapour pressure of water is greater, thus, at the same temperature and pressure, it will take less pressure to vapourize acetone.
Answer:
<h3>2CH3COOH(l)⇒⇒⇒⇒(CH3COOH2)+ + (CH3COO)-</h3>
Explanation:
Remember that, ionization is a process by which an atom or a molecule receives a negative or positive charge by gaining or losing electrons during a chemical reaction. However the auto-ionization reaction for acetic acid the two solvent molecules (CH3COOH2)+ + (CH3COO-) collide and a proton is transferred between them.
