Answer:
12.973 liters of H2S is required at STP.
Explanation:
The given equation is ,
<em>2H2S + 3O2 --> 2SO2 + 2H2O </em>, mass of reacting<em> O2 is 27.8 g</em>
The mole ratio is,
number of moles = m =
for O2, m = (molecular weight of <em>O2 is 32</em>)
number of moles of H2S is
now at STP, 1 mole of gas occupies 22.4 liters.
thus liters of H2S required are,
= 12.973 liters
i think its CaNO4 but im not sure
Answer: doing it right now
Explanation:
the picture
A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. The bond may result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bonds.
Answer:
6
Explanation:you find neutrons by subtracting the mass number from the proton for this example lithium's number of protons is 3 and mass number 9 so 9-3=6
