Answer:
Tetrahedral
Explanation:
SF2H2 is a derivative of the sulfuranes (SL4) compounds. The quantum mechanics of these sulfuranes is quite complicated.
Simply, they consist of ten electrons around the sulphur central atom one of which is a lone pair. The electronegativity of fluorine plays a key role in the structure and molecular geometry of SF2H2.
The molecule is found to be tetrahedral in shape by quantum mechanical calculations.
Answer:
8.82 gm of Pb
Explanation:
Question
calculate the Mass of lead that will be deposited from an aqueous solution of lead(2)salt by the same quantity of electricity that deposit 2.7 g of copper from an aqueous solution of copper (2)saltSince the oxidation# of the Pb and the Cu is the same, we know that the same amount of electricity that will deposit 1 mole of Cu will deposit 1 mole of Pb
2.7 gm of Cu were deposited
the atomic mass of Cu = 63.5
the number of moles of Cu deposited was 2.7/63.5 = 0.0425 moles
so 0.0425 moles of Pb will be deposited.
The atomic mas of Pb is 207.2
0.0425 mole of Pb weigh 0.0425 X 207.2 =
8.82 gm of Pb
Answer:
Explanation:
The reaction between methanol and oxygen can be expressed as an equation below:
However, the equation is not balanced as the number of the molecule of each atom on the right-hand side and the left-hand side is not the same. The balanced equation showing the phases of all the reactants and products is as below:
<em>Two molecules of liquid methanol react with three molecules of oxygen gas to give 2 molecules of carbon dioxide gas and four molecules of water vapor. </em>
Chemical weathering uses water, Mechanical weathering uses water too.

Answer: Formula: Mass = (Volume)(Density)
Iron Density = 7.87 g/cm^3
Volume of Iron = 55.2 cm^3
Mass=(V)(D)
Mass= (55.2 cm^3) x (7.87 g/cm^3)
Mass= 434,42 g
