Answer:
The concentration of Hydrogen Cation is:
Pure water is<u> NEUTRAL</u>
Explanation:
pH = It is negative logarithm of activity of Hydrogen ions.
![pH = - log(a_{[H^{+}]})](https://tex.z-dn.net/?f=pH%20%3D%20-%20log%28a_%7B%5BH%5E%7B%2B%7D%5D%7D%29)
Activity = concentration for dilute solutions
There are three types of solution based on pH:
1. Acidic solution : Those solution which have pH between 0 to 7 or less than 7 are acidic in nature . They turns blue litmus red.They contain more H+ ions than OH- ions
2. Basic : Those solution which have pH value greater that 7 of between 7 to 14 are basic in nature . They turn red litmus blue.They contain more OH- ions then H+ ions
3 . Neutral : Those solution which have pH = 7 are neutral . They are neither acidic nor basic in nature .They have equa;l concentration of H+ and OH- ions in the solution.
The given water has pH = 7 .This means it is neutral and has low H+ ion concentration in solution. The H+ ion are :
M in water.
OH- =
M in water
So overall neutral
A gas that occupies 4.31 litres at a pressure of 0.755 atm will have a temperature of 39.58°C. Details about temperature can be found below.
<h3>How to calculate temperature?</h3>
The temperature of a gas can be calculated using the following formula:
PV = nRT
Where;
- P = pressure
- V = volume
- n = number of moles
- R = gas law constant
- T = temperature
0.755 × 4.31 = 1 × 0.0821 × T
3.25 = 0.0821T
T = 3.25 ÷ 0.0821
T = 39.58°C
Therefore, a gas that occupies 4.31 litres at a pressure of 0.755 atm will have a temperature of 39.58°C.

Answer:
I'm pretty sure its a combination reaction!!
Explanation:
they generally form between metals and non metals like that^
The types of intermolecular forces that occur in a substance will affect its physical properties, such as its phase, melting point and boiling point.
KE = (1/2)mv^2
m = 10.0 kg
v = 5.00 m/a
KE = (1/2)(10.0)(5.00)^2 = (1/2)(10.0)(25.0) = 125 J
C. 125 J
