It is the polar nature of water that allows ionic compounds to dissolve in it. In the case of sodium chloride (NaCl) for example, the positive sodium ions (Na+) are attracted to the negative pole of the water molecule, while the negative chloride ions (Cl−) are attracted to the positive pole of the water molecule.
PH Answer/definition - A value from 0 to 14 that is used to specify how acidic or basically a compound of when it is dissolved in water.
Ions Answer/definition - An atom or molecule that has a positive of negative charge.
Acid Answer/definition - A compound that increases the hydroxide ions (OH-) when it is dissolved in a solution. (Arrhenius Acid)
Base Answer/definition - A compound that increases hydrogen ions (H+) when it is dissolved in a solution.
Hope this helps you out :)))
when the thermal energy is the energy contained within a system that is responsible for its temperature.
and when the thermal energy is can be determined by this formula:
q = M * C *ΔT
when q is the thermal energy
and M is the mass of water = 100 g
and C is the specific heat capacity of water = 4.18 joules/gram.°C
and T is the difference in Temperature = 50 °C
So by substitution:
∴ q = 100 g * 4.18 J/g.°C * 50
= 20900 J = 20.9 KJ
The term for a push or pull is called Force.
The answer is 23, 040 minutes. To solve this you can start by changing days in to hours. We know that there are 24 hours in a day. To find how many hours are in 16 days you multiply 24 by 16 which is 384. Next you must find out how many minutes are in 384 hours. we know there are 60 minutes per hour. To find how many minutes are in 384 hours, you multiply 384 by 60. To this you get 23, 040 which is your answer.
