Iodine would have chemical properties most like H. chlorine.
They would have similar chemical properties because they belong to the same group in the periodic system of elements, unlike manganese, tellurium, and xenon. To see which group these belong to, just look at the periodic system vertically.
Answer:
All of these
Explanation:
In MnO:
mass of Mn = 55 g (as 1 mole of Mn weighs 55 g)
mass of O = 16 g (as 1 mole of O weighs 16 g)
The mass percent of metal Mn= 
In MnO2:
mass of Mn = 55 g
mass of O = 2*16 = 32 g
The mass percent of metal Mn=
In Mn2O3:
mass of Mn = 2*55 = 110 g
mass of O = 3*16 = 48 g
The mass percent of metal Mn=
In all the cases the mass percent of metal is greater than 50.
For example, silicon has 14 protons and 14 neutrons. Its atomic number is 14 and its atomic mass is 28.
Answer:
1.27 atm.
Explanation:
The following data were obtained from the question:
Pressure (P) in torr = 968 torr
Pressure (P) in atm =...?
Thus, we can convert from torr to atm by doing the following:
Recall:
760 torr = 1 atm
Therefore,
968 torr = 968/760 = 1.27 atm
Therefore, 968 torr is equivalent to 1.27 atm.
