Must all four hydrogen atoms lie in the same plane? If not, what is the spatial relationship among them? Why?
RoseWind [281]

Answer:

We are considering an Allene molecule here, CH2CCH2. To answer your question, NO, they don't have to lie on the same plane. The spatial arrangement between them is that the center carbon that forms these pi bind in the left and right are PERPENDICULAR to each other.

Explanation:

We see here that The terminal carbons are sp2 hybridized, and form three σ-bonds each which means that each terminal carbon has one unhybridized p-orbital. The central carbon atom is sp hybridized, and forms two σ-bonds which means it has two unhybridized p-orbitals. For better understanding, let's call these two orbitals px and py. Summarily, These orbitals are perpendicular to each other

Answer:

Minerals

Explanation:

Minerals are usually defined as naturally occurring inorganic substances, that are comprised of specific chemical composition as well as having a well organized internal structure of atoms.

Different mineral forms under different conditions and under different geological settings. These minerals combine with one another giving rise to the formation of rocks.

They are characterized by the presence of both physical as well as chemical properties.

Example of some minerals includes, Calcite, Fluorite, Quartz, and Feldspar.

4 How many moles CH, are needed to produce 50 moles of CO2?
exis [7]

Answer:

50 mol CH₄

Explanation:

The question is incomplete so I looked it up online.

<em>How many moles CH₄, are needed to produce 50 moles of CO₂?</em>

Step 1: Write the balanced equation for the complete combustion of methane

CH₄ + 2 O₂ ⇒ CO₂ + 2 H₂O

Step 2: Establish the appropriate molar ratio

According to the balanced equation, the molar ratio of CH₄ to CO₂ is 1:1.

Step 3: Calculate the number of moles of CH₄ needed to produce 50 moles of CO₂

We will use the previously established molar ratio.

50 mol CO₂ × 1 mol CH₄/1 mol CO₂ = 50 mol CH₄

Paul [167]

Answer:

This question is incomplete

Explanation:

This question is incomplete, however it can be concluded that this question is testing concepts about equilibrium within a chemical reaction.

It is a rule that:

If a reactant is added, the forward reaction will be favored.

If a product is added, the reverse reaction will be favored.

The same principle can be applied if a reactant/product is taken away. The reaction will try and produce more of what is not there, and this will shift the equilibrium.
