The explanation for the large space between particles in a gas is provided by the kinetic theory (option C).

<h3>What is the kinetic theory?</h3>

The kinetic theory is a scientific theory used in physics to understand the behavior of gases.

This theory (kinetic theory) indicates that molecular distances in gases are small when compared to the molecular sizes.

In conclusion, the explanation for the large space between particles in a gas is provided by the kinetic theory (option C).

Find the percentage of mass in each of the element Ca ( HCO3)2 (Ca= 40, H = 1, O = 16, C= 35)​
Alex787 [66]

Answer:

% Ca = 24.69%

% H = 1.2%

% C = 14.8%

% O = 59.25%

Explanation:

The percentage by mass of each element can be calculated by dividing the mass of each element in the compound by the molar mass of the compound.

Molar mass of Ca(HCO3)2

Where; (Ca= 40, H = 1, O = 16, C= 12)

= 40 + {1 + 12 + 16(3)}2

= 40 + {13 + 48}2

= 40 + {61}2

= 40 + 122

= 162g/mol

- % mass of Ca = 40/162 × 100

= 0.2469 × 100

= 24.69%

- % mass of H = 2/162 × 100

= 0.012 × 100

= 1.2%

- % mass of C = 24/162 × 100

= 0.148 × 100

= 14.8%

- % mass of O = 96/162 × 100

= 0.5925 × 100

= 59.25%

Which of the following statements about benzene is true? Multiple Choice
fenix001 [56]

Answer: option a and d

Explanation:

Option A- Benzene undergoes substitution reaction

Example : benzene reacts with chlorine to form chlorobenzene, in the presence of Iron

(iii) chloride as a catalyst

C6H6 + Cl2 ---> C6H5Cl + HCl

Option D- Benzene also undergoes addition reaction

Example: benzene reacts with hydrogen , in the presence of nickel as a catalyst to form

cyclohexane

C6H6 + 3H2 ---> C6H12

Reasons why Option B isn't the answer

Although benzeme has degree of unsaturation but it's not five degree of unsaturation.

Benzene has 6 carbon atoms and 4 degrees of unsaturation (1 ring and 3 double

bonds).

If you work backwards and double the degrees of unsaturation you have 8 degrees of

unsaturation instead of 5.

Option C - Benzene isn't a saturated hydrocarbon

A. Clearly draw the Lewis structure for the PBr4- ion. Show your math where
Nataliya [291]

Answer:

   Br

    |

Br-P-Br

    |

   Br

Explanation:

To calculate the valance electrons, look at the periodic table to find the valance electrons for each atom and add them together. P is in column 5A, so it has 5, Br is in column 7A, so it has 7 (multiply by 4 since there are 4 Br atoms to give 28) and there is a 1- charge, so add one more electron. 5+28+1=34, so there are 34 electrons to place. P would be the central atom, so place it in the middle. Place each Br around the P (as shown above) with a a single line connecting it. Each line represents 2 electrons, so 8 total have been place, leaving 26 remaining. Place 6 electrons around each Br (2 on each of the unbonded sides), which leaves 2 electrons remaining. The remaining pair of unbound electrons will be attached to the P between any two Br atoms. Phosphorus doesn't have to follow the octet rule, so it actually ends up with 10 valance electrons.
