A rotational force, also known as a torque, depends upon the force and where that force is applied; torque = lever arm x force. The lever arm is the perpendicular distance from the force to the axis of rotation.
<h3><u>Answer;</u></h3>
= 0.0000001 mol/L
= 0.0000001 mol/L
= 1:1
<h3><u>Explanation;</u></h3>
What is the concentration of H+ ions at a pH = 7?
The formula for ph is given by:
pH=−log10[H+]
In calculating for the concentration of hydrogen ion, the formula is given by:
[H+]=(10)^(-pH)
Therefore; at pH = 7
[H+]=(10)^(-7)
<u>= 0.0000001 mol/L </u>
What is the concentration of OH– ions at a pH = 7?
pH+pOH=14
7+pOH=14
pOH= 7
[OH-]=(10)^(-pOH)
[OH-]=(10)^(-7)
<u>= 0.0000001 mol/L </u>
What is the ratio of H+ ions to OH– ions at a pH = 7?
1:1
The balanced formula is B.
The statement that describes the energy changes associated with evaporation and boiling is that atoms gain energy during evaporation and boiling.
<h3>What is evaporation?</h3>
Evaporation is defined as process by which a solution changes from its liquid state to gaseous state.
Boiling is defined as the heating of water to a point that the vapor pressure is equal to the pressure of the gas above it.
In both phase transition stages, the molecules gain enough energy to change its state to another state.
