ANSWER: Milk
Explanation: Take this chart from 1-6 are acids from 8-14 those are bases
Now bases are like cleaning products and stuff
While acids are like lemons and other stuff
If you look at milk level which is 6.5 It is an acid but its A lot closer to neutral Than Other acids

Answer:
The kinetic energy of the two stones is 320 J
Explanation:
Kinetic energy is the energy that a body possesses due to its movement. So it is the capacity or work that allows an object to go from being at rest, or still, to moving at a certain speed.
In other words, the kinetic energy of an object is that which is produced due to its motion and depends on its mass and velocity as follows:
where the kinetic energy Ec is measured in joules (J), the mass m is measured in kilograms (kg) and the velocity v in meters/second (m/s).
In this case you know that a 20 kg curling stone is sliding in a positive direction at 4 m/s. So:
- m= 20 kg
- v= 4 m/s
Replacing you have:
Ec₁= 160 J
A second curling stone slides at the same speed but in the opposite direction. So:
- m= 20 kg
- v= - 4 m/s
Replacing you have:
Ec₂= 160 J
The kinetic energy of the two stones is calculated as:
Ec= Ec₁ + Ec₂
Ec= 160 J + 160 J
Ec= 320 J
<u><em>The kinetic energy of the two stones is 320 J</em></u>
