5.33 Liters is the volume of 15.2 grams of SO2 at STP.
Explanation:
If the mass of the gas, then you can divide the mass by the molecular weight of the gas molecules to get the number of moles. Then multiply this by 22.4 Liters / mole to get the volume.
PV = nRT => The Ideal Gas Law.
Each unit occurs three times and the cube root yields L-atm / mol-K, the correct units for R when used in a gas law context.
PV / nT = R. or PV = nRT.
R is called the gas constant.
PV = nRT => V = nRT/P
n = moles SO₂ = 15.2g/64g·mol⁻¹ = 0.238 mole
R = Gas Constant = 0.08206 L·atm/mol·K
T = Kelvin Temp = 273K at STP
P = pressure in atmospheres = 1.0 atm at STP
∴ V = (0.238mol)(0.08206 L·atm/mol·K)(273K)/(1.0atm)
=> 5.33 Liters SO₂.

I personally think Thompson was most important. He discovered the electron and improved hugely on the atomic model with a positively charged sphere with negative electrons dispersed throughout, and the atom with a neutral charge.
I think that without him, Rutherford wouldn't have done his gold foil experiment. Since Rutherford discovered the nucleus is positive, Bhor was able to find electrons have energy levels and that wouldn't have happened without Rutherford, who happened because of Thompson.
Your answer is: Galium
Answer: A difference in voltage
Or potential difference
Explanation:Voltage, electric potential difference, electric pressure or electric tension is the difference in electric potential between two points. The difference in electric potential between two points in a static electric field is defined as the work needed per unit of charge to move a test charge between the two points.
Electric current is the flow of electrons in a conductor. For example, the first element has more positive charges, so it has higher potential. On the other hand, the second element has charges that are more negative so it has lower potential. The difference between two points is called potential difference

Answer: option B. Hydrogen
Explanation:
a) How many grams of iron can be made from 6 moles H2
223.4 g of iron can be formed from 6 moles of hydrogen gas.
Explanation:
Fe₂O₃(s) + 3 H₂(g) → 2 Fe(s) + 3 H₂O(l)
Since the given equation is the balanced one, we need 3 moles of hydrogen gas to make 2 moles of iron, so the molar ratio is 3:2. So, from 6 moles of hydrogen gas, we can make few moles of iron as,
Molar mass of iron = 55.85 g
So amount of iron produced = 4 moles × 55.85 g/mol = 223.4 g of iron
Ionic bond is formed when there is a transfer of electron(s) from metallic atom to non-metallic atom.
The correct answer to the question is Option B. A bond resulting from the transfer of 1 or more electrons
Ionic bond exist between a metal and a nonmetal.
In this bonding, the metal losses it's valence electron to form a stable metallic ion, while the nonmetal receives the electron from the metal to form a stable nonmetallic ion which results in the formation of an ionic compound.
With the above information, we can see that ionic bond involves a transfer of electron(s).
Thus, the correct answer to the question is Option B. A bond resulting from the transfer of 1 or more electrons.

Answer: B
Explanation:
Ionic bonding is the complete transfer of electron(s) between atoms. It is a type of chemical bond that generates two oppositely charged ions. In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion.
