Volume of a substance can be determined by dividing mass of the substance by its density.
That can be mathematical shown as:
Density=Mass/Volume
So, Volume=Mass/Density
Here mass of the substance given as 24.60 g
Whereas density of the substance is 2.70 g/mL
So,
Volume=Mass/Density
=24.6/2.7
=9.1 mL
So volume of the substance is 9.1 mL.
Answer:
A
Explanation:
Electrons are significantly smaller than neutrons and protons.
Electrons have a diameter of less than 10^-16 centimeters, whereas protons and neutrons have a radius of about 10^-13 centimeters.
I hope i didn t miss any. the triple bonding has to be between atoms that are fully saturated by other carbons ( cuaternar carbons)
All species are "(aq)" unless marked otherwise:
molecular: Na3PO4 + 3 AgNO3 → Ag3PO4(s) + 3 NaNO3
total ionic: 3 Na{+} + PO4{3-} + 3 Ag{+} + 3 NO3{-} → Ag3PO4(s) + 3 Na{+} + 3 NO3{-}
net ionic: PO4{3-} + 3 Ag{+} → Ag3PO4(s)
K2SO4(aq)+Na2CO3(aq) no reaction
molecular: Pb(NO3)2 + Na2CO3 → PbCO3(s) + 2 NaNO3
total ionic: Pb{2+} + 2 NO3{-} + 2 Na{+} + CO3{2-} → PbCO3(s) + 2 Na{+} + 2 NO3{-}
net ionic: Pb{2+} + CO3{2-} → PbCO3(s)
molecular: BaCl2 + 2 KOH → Ba(OH)2(s) + 2 KCl
total ionic: Ba{2+} + 2 Cl{-} + 2 K{+} + 2 OH{-} → Ba(OH)2(s) + 2 K{+} + 2 Cl{-}
net ionic: Ba{2+} + 2 OH{-} → Ba(OH)2(s)
