When _____________ light strikes an object, the _____________ of the object depends on how the object _____________ and/or _______________ the colors of light.
Answers
Answer:
When white light strikes an object, the color of the object depends on how the object absorbs and/or reflects the colors of light.
Explanation:
White light is composed of seven distinct colours of light; red, orange, yellow, green, blue, indigo and violet. These colors can be seen when white light is passed through a prism.
The color of an object depends on the colors in the light that falls on it and also on the ability of this object to absorb or reflect this light.
When white light strikes an object, the color of the object depends on how the object absorbs and/or reflect the colors of light.
For example, when white light falls on an object and the object appears green, it means that that object has absorbed all the other colors of white light but reflects green light.

What is a good reducing agent?
A. A substance that is good at oxidizing another atom
B. A substance that is good at reducing another atom
C. A substance that is a good electron acceptor
D. A substance that is easily reduced in a reaction
Answers
Answer:
B. A substance that is good at reducing another atom
Explanation:
Reducing agents:
Reducing agents reduced the other element are it self gets oxidized. They have very low ionization energy and easily lose the electron.
Consider the following reactions.
4KI + 2CuCl₂ → 2CuI + I₂ + 4KCl
the oxidation state of copper is changed from +2 to +1 so copper get reduced. It means it gain one more electron.
CO + H₂O → CO₂ + H₂
the oxidation state of carbon is +2 on reactant side and on product side it becomes +4 so carbon get oxidized. Carbon loses it two more electron and act as reducing agent.
Oxidizing agents:
Oxidizing agents oxidize the other elements and itself gets reduced.
Oxidation:
Oxidation involve the removal of electrons and oxidation state of atom of an element is increased.
Reduction:
Reduction involve the gain of electron and oxidation number is decreased.

How is the atomic number used to determine the identity of an atom
Answers
Answer:
"The number of protons in one atom of an element determines the atom's identity, and the number of electrons determines its electrical charge. The atomic number tells you the number of protons in one atom of an element. It also tells you the number of electrons in a neutral atom of that element."

Hope this helps:) Can I Pleasse have brainliest?!
The number of protons in an element's atom is represented by the element's atomic number. The atomic number identifies the element because the number of protons establishes the identity of the element.
What is atomic number ?The charge number of an atomic nucleus is the chemical element's atomic number, also known as nuclear charge number. This is the number of protons present in the nucleus of each atom of that element, or the proton number, for conventional nuclei.
The number of protons in an atom is the atomic number. It is sometimes referred to as the proton number for this reason. The capital letter Z is used to represent it in calculations.
The word zahl, which translates to "number of numerals" in German, or "atomzahl," a more recent word that means "atomic number," are the origins of the letter Z.
Thus, the number of protons in an element's atom is represented by the element's atomic number. The atomic number identifies the element because the number of protons establishes the identity of the element.
