A 65 kg diver jumps off a 10 m platform.
kramer

Answer:

1. 6.37 KJ

2. 3.185 KJ

Explanation:

Gravitational potential energy is a form of potential energy with respect to the force of gravity.

Gravitational potential energy = mass x acceleration due to gravity x height

i.e   PE = m x g x h

1. At the top of the platform; mass = 65 kg, acceleration due to gravity = 10 m/s^{2}, and height = 10 m.

Gravitational potential energy = 65 x 9.8 x 10

                                                  = 6370 Joules

The gravitational potential of the diver at the top of the platform is 6.37 KJ.

2. Halfway down; mass = 65 kg, acceleration due to gravity = 10 m/s^{2}, and height = 5 m.

Gravitational potential energy = 65 x 9.8 x 5

                                                  = 3185 Joules

The gravitational potential energy of the diver halfway down is 3.185 KJ.

How many lone pairs of electrons are on the central carbon atom in a Lewis Structure of CHI3?
Alborosie

There are zero lone pairs of electrons on the central carbon atom in a Lewis Structure of CHI3. The correct option is b.

Explanation:

Lone pair electrons are those valence electrons of an atom which do not take part in bonding or left after the bonds are formed.

CHI_{3}

carbon is the central atom in the compound having 4 valence electrons.

Each iodine molecule has 7 valence electrons.

H has 1 valence electron.

from the Lewis structure of CHI_{3}, it is seen that all four valence electrons of the carbon is involved in bonding with 3 atoms of iodine and 1 atom of hydrogen.

Thus when all valence electrons are involved in bonding no lone pair of electron is found in CHI_{3} that means zero lone pairs of electrons.

The octet of the iodine, carbon and hydrogen gets completed to form the compound.

Pls explain ionization energy​
Oliga [24]

Answer:the energy required by an atom to lose or gain electron (e-) to be able to form ions.either cation or anion.

Explanation:

to lose or gain e- an atom has to donate or receive e- to to this it requires the more easily it can lose an electron the more electro positive it is and the more easily it gains electron the more electro negative it is.

If 7.0 mol of NO and 5.0 mol of O2 are reacted tegethor. The reaction generates 3.0 mol of NO2. What is the percent yield for th
Daniel [21]

Answer:

Percentage yield = 30%

Explanation:

Given data:

Number of moles of NO = 7.0 mol

Number of moles of O₂ = 5 mol

Number of moles of NO₂ = 3 mol

Percentage yield = ?

Solution:

Chemical equation:

2NO + O₂ → 2NO₂

Now we will compare the moles of NO₂ with NO and O₂ .

                  NO           :               NO₂

                  2               :               2

                 7.0             :              7.0

                O₂               :                NO₂

                 1                 :                 2

                 5.0             :               2 ×5.0 = 10 mol

The number of moles of NO₂ produced by NO are less it will be limiting reactant.

Mass of NO₂ = moles × molar mass

Mass of NO₂ = 10 mol × 46g/mol

Mass of NO₂ =  460 g

Actual yield of NO₂:

Mass of NO₂ = moles × molar mass

Mass of NO₂ = 3 mol × 46g/mol

Mass of NO₂ =  138 g

Percentage yield:

Percentage yield = Actual yield/theoretical yield × 100

Percentage yield = 138 g/ 460 g × 100

Percentage yield = 30%
