Answer:
False
Explanation:
Lead sulfate is insoluble in water and sinks in water
(sorry if it's wrong)
Lithium-Chloride, Carbon-oxide, Barium Bromide, Ferrous Iodide, and Ammonium Chloride. Did this help?
The number of moles of gas in the sample of chlorine gas is calculated by use of ideal gas equation
that is PV=nRT
n=number of moles
R= gas constant ( 62.36367 l.torr/k.mol)
P=pressure
V=volume
from ideal gas equation n= PV/RT
n= (328 x5.0)/ ( 62.36367 x310)= 0.085 moles
Noble gases have a FULL balance she’ll with 8 electrons. Because their balance she’ll is full they DONT need to borrow or gain electrons
fyi it’s actually:
Noble gases have a full valence shell with eight electrons. Because their valence shell is full they don’t need to borrow or gain electrons.
The mass of NaCl produced is calculated as below
write the reacting equation
that is 2 Na + Cl2 =2 NaCl
by use of mole ratio between Na :NaCl which is 2 :2 t he moles of NaCl is also = 5.50 moles
mass of NaCl= moles x molar mass
=5.50 moles x58.5 g/mol = 321.75 grams
