The number of hydrogen ions would equal the number of hydroxide ions in a solution with a pH of 7.
<u>Explanation
:</u>
The substance’s acidic or basic nature is determined by its pH value which is the indication of the number of free hydrogen ion (
). The pH value and the alkalinity can be measured by pH scale which varies from 0 to 14. Neutral water has the pH value of 7 with equal number of hydrogen ions () and Hydroxide ions (
).
A substance with a pH value above than 7 is counted amongst the base whereas those with a pH value are counted amongst the acids. When a solution gets ten times more acidic, the pH value falls by the count of one.
There are various methods to determine the pH value of any substance and the most effective and quick one is the pH indicator paper. When the indicator paper is dipped in the water solution of the substance, it colour changes according to the different pH value. Another effective method to determine the pH value is the use of pH electrodes.
Yes energy makes things move
I think its
Mass and volume
Answer:
74 N to the right
Explanation:
the forces are going in opposite horizontal directions, meaning that they are directly opposing each other. this means that you can subtract the force applied in the direction that is greater from the direction that is less to get the net force for the greater direction
this means 182 N - 108 N = 74 N to the right
A
most common source of phosphates in the soil is the weathering of the mineral apatite.
Explanation:
Apatite is a group of phosphate minerals like hydroxylapatite, fluorapatite, and chlorapatite. When apatite rocks weather, they release the phosphate minerals mainly in the form of PO₄ ³⁻ . These minerals become dissolved in water (hydrosphere), where they are readily available to plants and other organisms in the biosphere. The phosphates are taken up and used in biosynthesis. When these organisms die and become buried with sediments, the phosphate gets back to the lithosphere as sedimentary rock.
