Answer: The value of the pH is 8.58
Explanation:
The pH is defined negative logarithm of the 
ions concentration in a given solution.
![[H^+]=2.6\times 10^{-9} M](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D2.6%5Ctimes%2010%5E%7B-9%7D%20M)
![pH=-\log[2.6\times 10^{-9}]=5.58](https://tex.z-dn.net/?f=pH%3D-%5Clog%5B2.6%5Ctimes%2010%5E%7B-9%7D%5D%3D5.58)
The value of the pH is 8.58
Answer:
d = 0.98 g/L
Explanation:
Given data:
Density of acetylene = ?
Pressure = 0.910 atm
Temperature = 20°C (20+273 = 293 K)
Solution:
Formula:
PM = dRT
R = general gas constant = 0.0821 atm.L/mol.K
M = molecular mass = 26.04 g/mol
0.910 atm × 26.04 g/mol = d × 0.0821 atm.L/mol.K×293 K
23.7 atm.g/mol = d × 24.1 atm.L/mol
d = 23.7 atm.g/mol / 24.1 atm.L/mol
d = 0.98 g/L
Answer:
Well yes and no
Explanation:
The molecules move, but in place. They are constantly vibrating, rotating and so forth.
Atoms do not move at all
You can use molar to measure concentration.
Answer: cause oxegeon is harmful then helium
