The correct answer is C) 8.7
The pH of a solution indicates the acidity or basicity of the answer. A solution is said to be neutral if the pH is 7, if the pH fee is less than 7 then it is acidic in nature and if the pH cost is greater than 7 then the solution is simple in nature.
Ph may appear as it belongs at the periodic desk of factors, however, it's truly a unit of size. The abbreviation pH stands for ability hydrogen, and it tells us how an awful lot hydrogen is in drinks—and the way active the hydrogen ion is.
PH is a measure of the attention of H+(aq) ions in an answer. The attention of H+ ions may be stated in mol dm(-three), but the use of the log(10) feature simplifies the numbers concerned. Definition: pH is the terrible logarithm to base 10 of the hydrogen ion awareness in an aqueous solution.

continental polar air mass
continental tropical air mass
maritime polar air mass
maritime tropical air mass
Answer: continental tropical air mass
Explanation:
The continental tropical mass of air forms over the Texas. It forms in the interior of the subtropical continents at about 150 to 350 North to South latitude. They can be characterized by the dry and hot air masses due to the temperature and moisture present in their source region. The tropical air masses originate in the tropical regions (warm regions) these typically have low air pressure.
Answer:
2
Explanation:
continental tropical air mass
B.) Atoms of Element
C.) Minerals
D.) Valences
Hello! Glad to help.
From what I have learned in my ICP class, molecules combine together to form componds. A compound is any molecule that is made up of two or more different elemental atoms.
Hope this helps you! Anymore questions? Just ask.
well ... there are sm common things between solutions and colloids
solutions even and fully mixed together and so are colloids
when we let solutions and colloids settle down both of them do not have boundaries ... the particles of colloids and solutions do not settle down
Both are liquids. Both will pass through filters without seperation.
You can see through a solution, as the ions of the solute are dissolved. A colloid is a suspension of insoluble ultra microscopic particles or large molecules in water or other liquid, kept in suspension by Brownian motion.
Answer:
the phosphate head mixes with water ;the fatty acid tails do not
Explanation:
If the candle was placed in a large, sealed jar that allowed it to burn for several minutes before running out of oxygen. The candle and jar are balanced by an equal weight. In this situation, the side with the lit candle would rise because the heat collects on the top of the jar and starts to make the jar lighter by carrying some of the wait, whether it be a little or a lot.
The side where the candle lit would rise due to accumulation of heat from burning of candle.
When the candle was placed in a large, sealed jar and allowed it to burn for several minutes before running out of oxygen, the heat accumulates at the upper part of the jar and as a result the warm air puts pressure on the jar.
If the gas pressure is larger than the weight of the jar. the jar will be lifted by the air otherwise it will remain the same so we can conclude that the motion of jar occurs due to the burning of candle which produces the air.
