Answer:
A) HCI( hydrochloric acid)
Explanation:
HCI is a strong acid because it has more number of hydrogen ions whereas acetic acid contains less number of hydrogen ions so its a weak acid
It is melting point process
The most basic level of organization that is involved in converting fuel or food into forms of energy, are found and compose living things. These are called cells.
Answer:
1.58 L
Explanation:
Use Boyle's law, which is defined as
p1v1 = p2v2
In this case we're solving for V2 because the rest of the variables are given.
p1 = 1.22 atm
v1 = 1.88L
p2 = 1.45 atm
v2 = ?
p1v1 = p2v2
(1.22 atm)(1.88L) = (1.45 atm)(v2)
v2 = (1.22 atm)(1.88L) ÷ (1.45 atm) = 1.58 L
Potential energy was high at the top of the ramp and kinetic energy increased while the skater went down the ramp. At the bottom of the ramp the potential energy went away. This is because kinetic energy is energy that a moving object has whereas potential is stored energy due to its position.
