Answer :

2. Hydrogen forms bonds through the overlap of 1s atomic orbitals and the sharing of electrons between atoms. Carbon forms bonds through the overlapping of sp hybrid atomic orbitals and the sharing of electrons between carbon atoms.

Explanation:

The H-H bond is formed by the overlap of two 1s orbitals and the sharing of electrons between the two atoms.

A carbon atom must use the overlap of hybridized atomic orbitals and the sharing of electrons to bond with another carbon atoms.

1. is wrong because H can use only its 1s orbital for bonding.

3. is wrong because C must share electrons to form a carbon-carbon bond.

4. is wrong because C does NOT use overlapping of 2s orbitals for bonding. It uses the overlap of hybridized orbitals.

5. is wrong because H must share electrons to form an H-H bond.

How many moles of h2o will be produced from 2.9 g of HCl reacting with Ca(OH)2?

Igoryamba

Answer:

0.080 mol

Explanation:

M(HCl) = (1.0 +35.5) g/mol = 36.5 g/mol

2.9g*1mol/36.5 g = 0.0795 mol HCl

Ca(OH)2 + 2HCl ---> CaCl2 + 2H2O

from reaction 2 mol 2 mol

given 0.0795 mol x mol

x = 0.0795 mol ≈0.080 mol

600.0 mL of air is at 20.0 c what is the volume at 60.0

pogonyaev

682mL

Explanation:

Given parameters:

Initial volume of air = 600mL

Initial temperature = 20°C

Final temperature = 60°C

Unknown:

Final volume = ?

Solution:

To solve this problem, we apply Charles's law';

Charles's law states that "at constant pressure, the volume of a given mass of gas is directly proportional to its temperature. "

Mathematically;

$\frac{V_{1} }{T_{1} } = \frac{V_{2} }{T_{2} }$

V₁ is the initial volume of air

T₁ is the initial temperature of air

V₂ is the final volume of air

T₂ is the final temperature of air

To proceed in solving this problem, we need to convert the given temperature to Kelvin;

T K = 273 + T°C

T₁ = 273 + 20 = 293K

T₂ = 273 + 60 = 333K

now input the parameters;

$V_{2} = \frac{V_{1} }{T_{1} } x T_{2} = \frac{600}{293 } x 333$

V₂ = 682mL
