An energy transformation from chemical to electrical to light energy is that a flashlight uses a battery to operate and the correct option is option B.
What is transformation of energy?An energy transformation is the change of energy from one form to another.
Energy transformations occur everywhere every second of the day. There are many different forms of energy such as electrical, thermal, nuclear, mechanical, electromagnetic, sound, and chemical.
The Law of Conservation of Energy states that energy can neither be created nor destroyed.
Therefore, An energy transformation from chemical to electrical to light energy is that a flashlight uses a battery to operate and the correct option is option B.

Explanation:
This equation shows the neutralization of sodium hydroxide and hydrochloric acid:
NaOH + HCl → H2O + NaCl
The reactant side of the chemical equation has (1/2/3/4) atom(s) each of sodium, oxygen, and chlorine. The reactant side also has (1/2/3/4) hydrogen atom(s). Count the numbers and kinds of atoms on the product side of the equation. The numbers and kinds of atoms on both sides of the chemical equation are (the same/not the same). So, this chemical equation is (balanced/not balanced) .

This passage describes a chemical reaction. Read the passage. Then, follow the instructions below.
Buttermilk is a dairy product that contains lactic acid (C3H6O3). The lactic acid makes buttermilk a useful ingredient in pancakes. When buttermilk is added to pancake batter, lactic acid combines with baking soda (NaHCO3) to make carbon dioxide gas (CO2). This gas forms bubbles in the batter, causing the pancakes to rise and become fluffy as they cook.

What are the forms of light energy in solar radiation and the colors in white light?
(it has to be atleast 2 sentences)
Answer:
Light is a kind of energy called electromagnetic radiation. There are many different forms of electromagnetic radiation, such as radio waves, microwaves, ultraviolet rays, and X-rays. Each form is characterized by a different wavelength. For example, radio waves can be several miles long, while gamma rays are smaller than atoms. The light that we see — visible light — falls somewhere in the middle of this "electromagnetic spectrum.

Plsss help!! What would happen to a cup of hot coffee left untouched for 10 minutes. Include in your response temperature, molecules, and kinetic energy.
Answer:
The overall temperature of the coffee would decrease because the coffee would transfer its thermal energy into the surrounding air. The molecules would slow down in movement because when the coffee was hot, they were moving around faster. Subsequently, the kinetic energy of those molecules would also decrease
Explanation:
