The number of hydrogen atoms that are in 4.40 mol of ammonium sulfide is 2.12 x10^25 atoms
calculation
find the number of moles of Hydrogen in ammonium sulfide (NH4)2S
that is 4.40 x number of hydrogen atoms in (NH4)2S ( 4x2= 8 atoms)
moles is therefore= 4.40 x8= 35.2 moles
by use of Avogadro's law constant
that is 1mole = 6.02 x10^23 atoms
35.2 moles=?
by cross multiplication
{35.2 moles x 6.02 x10^23} /1 mole = 2.12 x10^25 atoms
Answer:
A long uniformly charged wire has charge density λ=0.16μλ=0.16μC/m.
D will because water just turns from liquid to a gas by adding heat. That is a physical change. The other equations are chemical changes.
Answer:
5
Explanation:
just subtract 20-25 and 5 is left over which is how much the water when up with the rock.
