Answer:
600.7 moles
Explanation:
Applying,
PV = nRT................... Equation 1
Where P = Pressure of oxygen, V = Volume of oxygen, n = number of moles, R = molar gas constant, T = Temperature.
make n the subject of the equation
n = PV/RT............... Equation 2
From the question,
Given: P = 190 atm, V = 35 L, T = 135 K
Constant: R = 0.082 atm.dm³/K.mol
Substitute these values into equation 2
n = (190×35)/(135×0.082)
n = 600.7 moles of xygen
Answer:
(a) (i) All the elements of a group have similar chemical properties because they have same no. of valence electrons in their outermost shell. (ii) All the elements of a period have different chemical properties because they have different no. of valence electrons in their atoms.
Answer:
The answer to your question is:
Explanation:
a)
Metals: are shiny, malleable and ductile, they can conduct electricity and heat, form cations in aqueous solutions.
Nonmetals: non-lustrous, brittle, not good conductors of heat and electricity, form anions in aqueous solutions.
b)
Metals are located in the left side of the periodic table
Nonmetals are located in the right side of the periodic table.
c)
Metal are use to make pans because they are good conductors of heat and also are malleable and ductile.
Nonmetals are used to make sleeping bags and coolers because they do not conduct heat so they can isolate matter.
Answer:
<h2>36.09 L</h2>
Explanation:
The initial volume can be found by using the formula for Boyle's law which is
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume.
Since we're finding the initial volume
We have
We have the final answer as
<h3>36.09 L</h3>
