Calculate the pH of a solution if the concentration of hydroxide ions (OH-) is 3.6 x 10-11M?

Chemistry
1 answer:
baherus [9]3 years ago
7 0

Answer:

3.56

Explanation:

pH refers to a measure of hydrogen ion concentration. It measures acidity or alkalinity of a solution. It usually ranges from 0 to 14.

If pH of aqueous solutions at 25°C is less than 7 then they are acidic, while  aqueous solutions with a pH greater than 7 are alkaline.

Concentration of hydroxide ions = 3.6\times 10^{-11}

pH = -log \left ( 3.6\times 10^{-11} \right )=10.44

pOH = 14 - pH = 14 - 10.44 = 3.56

Is a planar carbon "backbone" possible for propane? Explain.
tankabanditka [31]

Answer:

Cyclopropane has a planar carbon back bone while propane does not

Explanation:

We have to recognize that in straight chain saturated organic compounds, carbon atoms have a tetrahedral geometry. Each carbon atom is bonded to four other atoms.

However, carbon atoms in cyclic compounds are also sp3 hybridized with each carbon bonded to only four other atoms but the ring system is highly strained.

Cyclopropane is a necessarily planar molecule with a bond angle that is far less than the expected tetrahedral bond angle due to strain in the molecule. Hence, the carbon atoms may have have a "planar backbone".

Think about your morning from when you wake up until you arrive at school. Describe the forms of energy you encounter or use dur
denis-greek [22]

Answer:

When sleeping the energy exhibited is Potential energy. When I wake up and I’m preparing for the day I use kinetic energy which is the energy exhibited during motion.

Eating before leaving the house means I used chemical energy for replenishment of nutrients to aid the performance of more activities for the day. The food eaten and the physical activities also give rise to thermal energy which is why we sweat.
