Nuestra alimentación ha empeorado tanto y la oferta de alimentos no saludables (ultraprocesados ricos en sal, grasas y azúcares) es tan amplia, que debemos hacer un esfuerzo en reaprender y reconocer los alimentos que benefician nuestra salud. ¿Qué alimentos debemos escoger para preparar un plato saludable?
Answer:
Nuestra alimentacion debe estar basada en alimentos ricos en vitaminas, minerales como las frutas verduras, legumbres y semillas.
Explanation:
Los alimentos ultraprocesados son altos en sodio, conservantes, y pobres en vitaminas, es por eso que deben ser evitados ya que algunos hasta se consideran hasta carcinogenos.
No se descarta los compuestos quimicos ultraprocesados ricos en grasa perjudiciales para la salud ya que fomentan la formacion de placa de ateromas.
Compare the potential energy of two atoms chemically bonded to their potential energy when separated.
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 .

Convection currents in Earth's mantle are caused by the rise of hot material rising towards the crust, becoming cooler and sinking back down. This process occurs repeatedly, causing the currents to constantly flow. The movement of the currents plays a factor in the movement of the mantle.
Answer:
True or False
Answer - True
Explanation:
The mantle convection clearly describes how the mantle moves, transferring heat from the white-hot core to the lithosphere. The mantle is usually being heated below and the cooling happens above and the general temperature of the area gets dropped over a long period of time.
Hot buoyant Magma is being transferred through convection currents, to the lithosphere at the plate boundaries and hot spots. Also, convection current moves cooler materials from the crust to the interior of the earth through a process that is widely known as subduction.
Which periodic table trend is represented by the blue arrows?
Answer:
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.

On a .75-meter table sits a book whose mass is .5 kilograms. How
much Potential energy does it have?
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]
1 kg*m/s²= 1 Newton[tex]E_p=(4.9 \ N)(0.75 \ m)[/tex]
[tex]E_p=3.675 \ N*m[/tex]
1 N*m= 1 Joule[tex]E_p=3.675 \ J[/tex]
The book has 3.675 Joules of gravitational potential energy.

An ion with 11 protons 12 neutrons and a charge of + 1 has an atomic number of
what? And how many electrons total?
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.
If you start with 3 moles of sodium and 3 moles of chlorine to produce sodium chloride, what is the limiting reagent?(You will need to balance
the equation first.)
Na + Cl2 -> NaCl A. They are equal B. Na C. Cl2 D. NaCl
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. [It'd be wise to utilize stoichiometric factors to get a good grasp of this]

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.
