Answer:
h
Explanation:
hence co2 has a linear molecular goemetry with the bond angles of 180 degrees and symmetric distribution of electrons. CO2 Lewis structure, molecular goemetry hybridization in carbon dioxide molecule, the central carbon atom is surrounded by two areas of electrons density
Answer:
25.05 g of S₈
Explanation:
The balance chemical equation for given synthetic reaction is,
S₈ + 8 O₂ → 8 SO₂
Step 1: <u>Calculate Moles of SO₂ at STP:</u>
According to Avogadro's Law, at STP (0 ° C and 1 atm) every ideal gas occupies 22.4 L of volume. Therefore, the moles contained by 17.5 L of SO₂ are as;
Moles = 17.5 L / 22.4 L
Moles = 0.781 moles of SO₂
Step 2: <u>Calculate Moles of S₈ consumed:</u>
According to balance equation,
8 moles of SO₂ were produced by = 1 mole of S₈
So,
0.781 moles of SO₂ will be produced by = X moles of S₈
Solving for X,
X = 0.781 mol × 1 mol / 8 mol
X = 0.0976 moles of S₈
Step 3: <u>Calculate Mass of S₈ as;</u>
Mass = Moles × M.Mass
Mass = 0.0976 mol × 256.52 g/mol
Mass = 25.05 g of S₈
The molecular formula stays SF4. (Also, I think you mean 108.1g/mol)
Answer:
C.) It dissolves into Hydroxide ions in water (OH-)
Explanation:
A.) is incorrect because acids dissolve into hydrogen ions, not bases.
B.) is incorrect because acids have a pH lower than 7. Bases have a pH higher than 7.
C.) is correct because this is the defining characteristic of bases.
D.) is incorrect because bases can dissolve oils. This means they can be mixed.
