"
Explanation:
We arrange oxoacids to decrease the intensity of acids in this question. Or we may conclude all this from strongest to weakest acids they order oxoacids, that's why above given order is correct.
Answer:
22.5 mL
Explanation:
We are given an amount of a fluid in a graduated cylinder and required to determine its volume.
Liquids always take the shape of the container they are placed in. In the graduated cylinder shown, note how the top of the fluid curves downwards. The volume of the liquid is usually determined at the bottom of this curve or what is called the meniscus.
The bottom of the meniscus is at the 22.5 mL level and thus the volume of the fluid is 22.5 mL
Answer:
Δm = 3.0684
Explanation:
Data Given:
Atomic number of lithium = 3
Atomic mass of lithium = 7.0144 amu
Mass of 1 proton = 1.0073 amu
Mass of 1 neutron = 1.0087 amu
Solution:
Mass Defect:
Mass defect is the difference of mass number of an atom and its atomic number.
Formula used
Δm = [Z (mass of proton + mass of nutron) + ( A − Z ) mass of nutron] − m of atom
where:
Δm = mass defect (amu)
Z = atomic number
A = mass number
Put values in formula
Δm = [3 ( 1.0073 amu + 1.0087 amu) + ( 7 − 3 ) 1.0087 ] − 7.0144
Δm = [3 (2.016) + (4) 1.0087 ] − 7.0144
Δm = [(6.048) + (4.0348) ] − 7.0144
Δm = 10.0828 − 7.0144
Δm = 3.0684
