Actually, we can answer the problem even without the first statement. All we have to do is write the reaction for the production of sulfur trioxide.
2 S + 3 O₂ → 2 SO₃
The stoichiometric calculations is as follows:
6 g S * 1 mol/32.06 g S = 0.187 mol S
Moles O₂ needed = 0.187 mol S * 3 mol O₂/2 mol S = 0.2805 mol O₂
Since the molar mas of O₂ is 32 g/mol,
Mass of O₂ needed = 0.2805 mol O₂ * 32 g/mol = 8.976 g O₂
Answer:B
Explanation:
The early theory says that atom Is the smallest indivisible particle. Which was later proven to contain electron neutron and proton
2 and 3, because there are the protons and neutrons which have a greater mass than the electrons which are found in the locations 1 and 4.
Explanation:
The atom contains a nucleus, which is made from protons and neutrons, and electrons which are found around the nucleus.
The mass of the atoms is concentrated in the very tiny space represented by the nucleus. Of course the electrons have a mass too, but is very small compared to the protons and neutrons, and we usually neglect its mass.

Answer: A composite volcano is the most common type of volcano. They have non-explosion and explosion eruptions. There crater is big, or small. They are also called Stratovolcanoes.
Explanation:
Answer:
7.67578 ml
Explanation:
assuming the missing information
Conc. of nitric acid = 70.3% by mass
density =1.41 g/ml
Now, moles of HNO3 required = final volume× final conc.
= 1.15×0.105= 0.12075 mol
Mass of HNO3 required = moles×molar mass of HNO3
= 0.12075×63.01=7.6084575 g
mass of solution = 100/70.3 of 7.6084575
=10.82284 g
therefore, volume of the solution = mass/density
= 10.82285/1.41
= 7.67578 ml
