Answer:
The water would be neutral, (usually 7). The salt water would be the same (7) and the vinegar would be very acidic. (probably 2).
Explanation:
Answer : When we consider the atmospheric pressure as 1 atm then according to the ideal gas equation we can find out the molar mass of any unknown by this formula ;
PV=nRT
so if the pressure increases than 1 atm then we can see from the above equation that it will result in greater value for the number of moles (n) in the above equation.
While n = m/M where m is mass of the unknown in g and M is molecular mass.
So, if pressure is higher then it will result in molar mass of unknown which is much smaller.
Answer: The change in the volume of the balloon is 144.4L
Explanation: Please see the attachments below
One thing incorrect is that when dealing with a compound, such as H2SO4, that has 7 atoms in the chemical formula, the polyatomic ion SO4 doesn’t dissociate into one Sulfur and four Oxygens. SO4 stays and a PAI.
Weathered debris is a result of FROST WEDGING.
Frost wedging refers to the process by which water freeze and thaw continuously over a period of time. Rocks usually contain crevices which are filled with water. Due to the extreme temperature changes during the night and day and during the course of season changes, the water in the crevices freeze and thaw continuously leading to the cracking of the rocks as a result of the expansion and contraction of the rocks.<span />
