Sulfur reacts with oxygen to yield SO3 as shown in the equation below;
2S(g)+ 3O2(g) = 2SO3(g)
From part A 7.49 g of S were used.
The atomic mass of sulfur is 32.06 g/mol
Hence, the number of moles of sulfur used
7.49 / 32.06 = 0.2336 moles
The mole ratio of S : SO3 is 1:1
Thus the mass of SO3 will be ( 1 mol of SO3= 80.06 g)
0.2336 moles × 80.06 = 18.7 g
Answer:
the first one I believe is right but I could be wrong.
Answer:
it's not
Explanation:
gasoline is not soluble in water in gasoline is a complex mixture of nonpolar compounds such as long-chain hydrocarbons etc water is a polar molecule as a result of the gasoline molecules cannot enter water and borla solution
It's the last answer. The gas-filled sacs allow for it to float, which means it's closer to the surface where the sun is. The top of the kelp collects the nutrients it needs from the sunlight and transfers it throughout the rest of it. Hope this helped!
The answer is (4) zinc. Zinc can react with HCl at room temperature spontaneously and create H2. You can know this property from the metal activity order.
