Answer:
D.
Explanation:
-log(1.0x10^-5) = pH
pH + pOH = 14 (rearrange it)
OH- = 10^-pOH = 1.0 x 10^-9

Are alchemy and chemistry the same: No
<u>Explanation:</u>
Alchemy and chemistry differ from each other. Their main difference lies in the concepts that they are based on. Alchemy has the base of viewing the reality of nature supernaturally. Chemistry has a base of viewing the reality in a natural way.
Protoscience is the name given for Alchemy. This is because that alchemy usually focuses on the traditional things like procedures and terminologies. Chemistry always focuses on the matter and their transformations. The matter and its transformations are dealt with chemistry.
Not sure what the question is, but a pi bond is created by the sideways overlap of two p orbitals :)
GravitationL force is equal to the mass of the object multiplied by the acceleration due to gravity. Assuming that this object is on earth, the acceleration due to gravity is 9.8 m/s^2. Therefore, 10 kg multiplied by 9.8 m/s^2 is equal to 98 N for the gravitational force.
Therefore, the gravitational force acting on an object that has a mass of 10.0 kg (assuming this object is on earth) is 98 N.
