Answer:

11 electrons total and 23amu

Explanation:

This tells us that sodium has 11 protons and because it is neutral it has 11 electrons. The mass number of an element tells us the number of protons AND neutrons in an atom (the two particles that have a measurable mass). Sodium has a mass number of 23amu.

Explanation:

Answer:

See explanation

Explanation:

The essence of chemical bonding is in order to attain minimum energy. The minimum energy state is the most stable state of a chemical system.

As the distance of separation between atoms decreases, the potential energy of the system decreases accordingly.

An optimum distance is reached when the two atoms attain the lowest potential energy. This is designated as the bond distance of the two atoms.

Hence two atoms have lower potential energy when bonded than when separated at large distance.

When two atoms are chemically bonded they have Lower potential energies while when they are separated they have higher potential energies

The potential energies of atoms chemically bonded is directly proportional to the distance between the atoms ( i.e as the distance between atoms decrease the potential energies of the atoms decreases accordingly)  and this enables chemically bonded atoms to attain a more stable state.

The lower the potential energy of bonded atoms the more stable the element/compound  becomes therefore it is necessary that bonded atoms attain the least possible potential energy.

Hence we can conclude that When two atoms are chemically bonded they have Lower potential energies while when they are separated they have higher potential energies .

Answer:

P.E = 3.675  J

Explanation:

Given data:

Height of table = 0.75 m

Mass of book = 0.5 kg

Potential energy = ?

Solution:

Formula:

P.E = mgh

g =acceleration due to gravity =  9.8 m/s²

by putting values,

P.E = 0.5 kg× 9.8 m/s² ×0.75 m

P.E  = 3.675 kgm²/s²

J = kgm²/s²

P.E = 3.675  J

Answer:

[tex]\boxed {\boxed {\sf 3.675 \ Joules}}[/tex]

Explanation:

Gravitational potential energy can be found using the following formula.

[tex]E_p=m*g*h[/tex]

Where m is the mass, g is the gravitational acceleration, and h is the height.

The mass of the book is 0.5 kilograms. The acceleration due to gravity on Earth is 9.8 m/s². The height of the book is 0.75 meters.

[tex]m= 0.5 \ kg \\g= 9.8 \ m/s^2 \\h= 0.75 \ m[/tex]

Substitute the values into the formula.

[tex]E_p=(0.5 \ kg)(9.8 \ m/s^2)(0.75 \ m)[/tex]

Multiply.

[tex]E_p=(4.9 \ kg*m/s^2)(0.75 \ m)[/tex]

[tex]E_p=(4.9 \ N)(0.75 \ m)[/tex]

[tex]E_p=3.675 \ N*m[/tex]

[tex]E_p=3.675 \ J[/tex]

The book has 3.675 Joules of gravitational potential energy.

Answer:

Balanced.

Explanation:

Both sides are pulling with equal force.

Answer/Explanation:

These forces are balanced. In order for forces to be balanced they must be pulling/pushing the same amount of net force in opposing directions.

In order for forces to be balanced they must be pulling/pushing in opposing directions but with differentiating net force.

Answer:

Yes they are triglycerides

Explanation:

Triglycerides are esters derived from glycerol and three fatty acids.

If we look at the structures closely, we will notice that the compounds are composed of glycerol and three fatty acids.

Hence the structures are triglycerides. The first structure is an unsaturated triglyceride while the second structure is a saturated triglyceride.

Answer:

B. Na

Explanation:

Once balanced you get 2Na + Cl₂ ⇒ 2NaCl. Sodium is the limiting reagent because it would produce the smallest amount of the product (NaCl)–while chlorine is the excess reagent. Based off of the Na in the balanced equation, it would produce 3 moles of NaCl, and for Cl₂ it would produce an excess of 6 moles of NaCl.

Periodic trends are specific patterns that are present in the periodic table that illustrate different aspects of a certain element, including its size and its electronic properties. Major periodic trends include: electronegativity, ionization energy, electron affinity, atomic radius, melting point, and metallic character. Periodic trends, arising from the arrangement of the periodic table, provide chemists with an invaluable tool to quickly predict an element's properties. These trends exist because of the similar atomic structure of the elements within their respective group families or periods, and because of the periodic nature of the elements.
