I don't think <u>C. Ribose</u> is a lipid. Lipid's are compounds soluble in one or more organic solvents, but insoluble in water
Let's break this down. We know from our balanced equation that (in theory) we'll get the same number of moles of copper out of the reaction that we put into it. So we need to find the number of moles of CuSO4 we have in 200.0 grams. Using the molar mass of CuSO4:
200.0 grams CuSO4 * (1 mole CuSO4)/(159.61 grams CuSO4) =
1.253 moles CuSO4
We know that the moles of CuSO4 and Cu are one-to-one, so we should yield the same number of moles of copper. If we multiply by copper's molar mass, we get:
1.253 moles Cu * (63.55 grams Cu)/(1 mole Cu) = 79.63 grams Cu
Reaction: CS₂ + 3 O₂ → CO₂ + 2 SO₂
For every mole of CS₂, 3 moles of Oxygen formed.
So, Number of moles of CS₂ = 2.14/3 = 0.713 mol
Now, Number of moles = Given mass / Molar mass
Mass = Molar mass * Number of moles
Mass = 76 * 0.713 [ Molar mass of CS₂ = 76 g/mol ]
Mass = 54.21 g
In short, Your Final Answer would be: 54.21 Grams
Hope this helps!
Answer:
The answer to your question is below
Explanation:
Ionic bond is a kind of bond in which a metal attaches to a nonmetal. Also we know that a molecule has ionic bonding if the electronegativity is higher than 1.7.
Kind of elements Difference of electronegativity Bond
a) MgO Metal - Nonmetal 3.44 - 1.31 = 2.13 Ionic
b) SrCl₂ Metal -Nonmetal 3.16 - 0.95 = 2.21 Ionic
c) O₃ Nonmetal- Nonmetal 3.44 - 3.44 = 0 Covalent
d) CH₄O Nonmetal-Nonmetal 3.44 - 2.55 = 0.89 Covalent
Carbon, Hydrogen and oxygen are nonmetals
2) Silver coins can conduct electricity.
