One fitness magazine suggested that the food that you eat is like a battery because it has energy. Do you think that
the banana that Mila ate had energy? Explain why you think this
Answer:
Explanation:
In this case, the fitness magazine compared the food we eat with a battery because the food provides energy for the human body to perform its daily activities.
The banana is an excellent source of energy, as it is a fruit with a high content of carbohydrates and fructose, it is an excellent food to be eaten before physical exercise, as it provides the muscles with enough energy to increase performance before and after exercise. , is a fruit rich in potassium, magnesium, phosphorus, and vitamins a and c, which gives greater strength and energy.

List and describe six forms of energy.
Answer:
Gravitational energy, electric energy, magnetic energy, nuclear energy, thermal energy, chemical energy.
Explanation:
gravitational energy - the energy resulting from the attraction of two masses to each other
electric energy - energy from a static or moving electrical charge.
magnetic energy - energy from the attraction of opposite magnetic fields, repulsion of like fields, or from an associated electric field
nuclear energy - energy from the strong force that bonds protons and neutrons in an atomic nucleus
thermal energy - also called heat, this is energy that can be measured as temperature. It reflects the kinetic energy of atoms and molecules
chemical energy - energy contained in chemical bonds between atoms and molecule
mechanical energy - the sum of the kinetic and potential energy
radiant energy - energy from electromagnetic radiation, including visible light and x-rays (for example)
Ciara’s bike has rusted, which means that the iron in the metal changed to rust.
What has occurred?
an energy formation
an exothermic reaction
a chemical reaction
a precipitate formation
Answer:
CChem Reaction
Explanation:
Cuz it big brain time
The iron in the metal changed to rust, which is a chemical reaction. Therefore, option (C) is correct.
What is the rusting of iron?The rusting of iron is an oxidation reaction in which the iron combines with oxygen in the air in the presence of water to produce Fe₂O₃.xH₂O, a hydrated iron (III) oxide.
This hydrated iron (Ill) oxide is rust and the color of rust is reddish-brown. This reddish-brown rust can be seen on iron nails, pipes, and railings. on. Rust is formed when the iron is exposed to oxygen in the presence of moisture and is not an instantaneous reaction. Rusting of iron takes place over a long period of time.
Fe (s) + O₂ (g) + xH₂O (l) → Fe₂O₃. xH₂O (s)
The oxidation state of iron increases which is followed by the loss of electrons as a result of the rusting reaction. Iron(III) oxide or ferric oxide has the iron atom has an oxidation state of +3.

How many atoms in 134 moles of an element B?
Answer:
8.06966961e+25
Explanation:
Atom = Mole / 6.0221415E+23
1 Mole = 6.0221415E+23 Atom
Answer:
8.06948e+25 atoms
Explanation:
mole = number of particles/avogadro number
number of atoms = mole × avogadro number
number or atoms = (134) x (6.022× 10²³) = 8.06948e+25 atoms
Do you think MgO has a higher or lower
melting point than NaCl? Why?
Answer:
Magnesium Oxide (MgO) has a higher melting point than Sodium Chloride (NaCl) which is around 2,800 degrees Celcius. This is because its Mg2+ and O2- ions have a greater number of charges, and so form stronger ionic bonds, than the Na+ and Cl– ions in Sodium Chloride.
1Which statement about plant cells is true? A A plant cell cannot contain both a nucleus and chlorophyll. Incorrect answer B A plant cell can contain both chlorophyll and a nucleus. Incorrect answer C A plant cell must contain chlorophyll, but can have no nucleus. Incorrect answer D A plant cell has neither a nucleus nor chlorophyll.
Answer:
B A plant cell can contain both chlorophyll and a nucleus.
Explanation:
All plants are eukaryotic organisms i.e the cells of all plants possess a membrane-bound nucleus that houses their genetic material (DNA). In addition to this, most plant cells also contain a unique organelle called CHLOROPLAST, which they use to capture the energy from sunlight in order to perform a process called PHOTOSYNTHESIS.
According to this question, plant cells can contain both chlorophyll and a nucleus. They can possess chlorophyll because chlorophyll is a pigment in their chloroplast that captures the light energy.
A sample of gas has a volume of 10 ml at 2 atm. The pressure increases to 4 atm. What is the new volume?
Answer:
The answer is 5 mLExplanation:
In order to find the new volume we use the formula for Boyle's law which is
[tex]P_1V_1 = P_2V_2[/tex]
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
Since we are finding the new volume
[tex]V_2 = \frac{P_1V_1}{P_2} \\[/tex]
We have
[tex]V_2 = \frac{10 \times 2}{4} = \frac{20}{4} \\ [/tex]
We have the final answer as
5 mLHope this helps you

The diagrams below represent three phases of matter labeled A,B and C. Which table correctly identifies the phases of matter represented by the diagrams? *
Answer:
The correct answer is 1
Explanation:
From the above, we will note the following:
Diagram A is liquid because it takes the shape of its container and it also has a specific volume. The particles are not tightly packed.
Diagram B is gas because the particles are freely moving colliding with one another and with walls of the container.
Diagram C is solid because the particles are tightly packed and are not freely moving.
Therefore, Option 1 is the correct answer.
Answer: 1
Explanation: My professor said it was correct
