What geometric shape is the carbon dioxide molecule? The Lewis structure for CO2 contains two double bonds.

Chemistry

adelina 88 [10]3 years ago

Answer: Linear

Explaination: The central atom of a carbon dioxide molecule is carbon. Carbon is tetravalent which just means it has 4 valence electrons. Because the valence shell isn’t full, the carbon atom can bond with other atoms creating a total of 4 bonds. This then allows the carbon to double bond with 2 oxygen atoms. Now, the atoms in the CO2 molecule Don’t share the electrons evenly because of atomic number or proton count. Because oxygen has an atomic number of 6, carbon has an atomic number of 4, and opposites attract (referring to the positivity of the nucleus and the negativity of the shared electrons), the oxygen atoms will have a slightly negative charge (-) and the oxygen will have a slightly positive charge (+ ). Therefore, the slightly negative oxygen atoms repel creating that linear shape.

What is the slowest type of mass movement?
LiRa [457]

Answer:

Creep

Creep is the slowest of all the mass movements and moves the most soil out of all the mass movements. The only way to detect soil creep is to observe the fences, buildings, and other surface objects that may be in that area. As the loosened soil moves slowly downslope, these objects will move along with the soil.

4. Calculation of theoretical yield and percent yield You balanced this reaction earlier: Mg(s) + HCl (aq) H2 (g) + MgCl2 (aq) Y
erik [133]

Answer:

Mg(s) +<em> 2</em> HCl (aq) →  H₂(g) + MgCl₂

0.415g of H₂(g) <em>-Assuming mass of Mg(s) = 10.0g-</em>

Explanation:

Balancing the reaction:

Mg(s) + HCl (aq) →  H₂(g) + MgCl₂

There are in products two atoms of H and Cl, the balancing equation is:

Mg(s) +<em> 2</em> HCl (aq) →  H₂(g) + MgCl₂

<em>Assuming you add 10g of Mg(s) -Limiting reactant-</em>

<em />

10g of Mg are (Atomic mass: 24.305g/mol):

10g × (1 mol / 24.305g) = <em>0.411 moles of Mg</em>

<em>-Theoretical yield is the amount of product you would have after a chemical reaction occurs completely-</em>

Assuming theoretical yield, as 1 mole of Mg(s) produce 1 mole of H₂(g), theoretical yield of H₂(g) is 0.411moles H₂(g). In grams:

0.411mol H₂(g) × (1.01g / mol) = <em>0.415g of H₂(g)</em>
