Anything greater that 7 is a base....so 13 would be a very strong base for example a drain cleaner. Hopefully this is what you are looking for.
Answer:
V = 27.98 L
Explanation:
Given data:
Mass of CO₂ = 33.0 g
Pressure = 500 torr
Temperature = 27°C
Volume occupied = ?
Solution:
Number of moles of CO₂:
Number of moles = mass/molar mass
Number of moles = 33.0 g/ 44 g/mol
Number of moles = 0.75 mol
Volume of CO₂:
PV = nRT
R = general gas constant = 0.0821 atm.L/ mol.K
Now we will convert the temperature.
27+273 = 300 K
Pressure = 500 /760 = 0.66 atm
By putting values,
0.66 atm×V = 0.75 mol × 0.0821 atm.L/ mol.K × 300 K
V = 18.47 atm.L/0.66 atm
V = 27.98 L
Yes because of the gas combination.
Answer: There are moles present in particles.
Explanation:
According to the mole concept, 1 mole of a substance contains particles.
Hence, number of moles present in particles are calculated as follows.
No. of moles = mol
= mol
Thus, there are moles present in particles.
Answer:
you should study.
Explanation:
it depends on when the exam is, but remember to make sure you study well for it and dont rely on studying it all the night of the exam.
