Answer:
Electrons are particles that surround the nucleus of an atom like a cloud. As with protons and neutrons, electrons are essential to an atom's structure.
Answer:
Energy
Explanation:
A wave is a disturbance that transfers energy from one place to another. During this transfer of energy, matter is not usually affected. Waves can be propagated through a material medium or in a vacuum.
Waves that are propagated in a material medium are called mechanical waves.
Those propagated through a vacuum are the electromagnetic waves.
Answer: SO2(Sulfur Dioxide) Molecular Geometry & Lewis Structure
Explanation: So2Molecular Geometry
We know that the shape which minimizes the repulsions of electronics pairs is adopted by the molecule to form the structure. The molecular shape of SO2 is same as the molecular geometry of Carbon Dioxide (CO2). We will show the bonding of SO2 without making assumption below.
O =S =O
Answer:THINNER contains more effective for measurin
Explanation:
Answer:
The answer to your question is 1 mol of Fe₂O₃
Explanation:
Data
mass of Fe = 112 g
mass of Fe₂O₃ = ?
Balanced chemical reaction
Fe₂O₃ + 3CO ⇒ 2Fe + 3CO₂
Process
1.- Calculate the molar mass of Fe₂O₃ and 2Fe
molar mass Fe₂O₃ = (56 x 2) + (16 x 3) = 160 g
molar mass of Fe = 56 x 2 = 112 g
2.- Use proportions to calculate the mass of Fe₂O₃ formed
160 g of Fe₂O₃ ----------------- 112 g of Fe
x ----------------- 112 g of Fe
x = (112 x 160)/112
x = 160 g of Fe₂O₃
3.- Calculate the moles of Fe₂O₃
160 g of Fe₂O₃ ------------------ 1 mol
160 g of Fe₂O₃ ------------------ x
x = (160 x 1)/160
x = 1 mol of Fe₂O₃
