Looking at the chemical reaction above, 32 grams of Oxygen gas combine with an unknown amount of Carbon to produce 44 grams of Carbon dioxide when heat is added. What is the unknown amount of carbon in this chemical reaction?
Answer:
12 g of C.
Explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
O2 + C —> CO2
Finally, we shall determine the mass of O2 and C that reacted. This can be obtained as follow:
Molar mass of O2 = 16 × 2 = 32 g/mol
Mass of O2 from the balanced equation = 1 × 32 = 32 g
Molar mass of C = 12 g/mol
Mass of C from the balanced equation = 1 × 12 = 12 g
Thus, from the balanced equation above, 32 g of O2 reacted with 12 g of C.

How is the atomic number used to determine the identity of an atom
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."
Explanation:

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.

What is the value of f(4)
Answer:
I'm not sure if this is what your looking for but, the ordered pair would be 2,4
Explanation:
the line intercepts the y axis at point 2 and same on the x axis the line intercepts at 4
The graph below represents a function. The value of f(4) is -4
What is function?Function is defined as a phrase, rule, or law defining a relationship between one variable and another.
Functions are common in mathematics and are required for the formulation of physical relationships in the sciences.
There are various types of functions.
Liner functionIdentical functionQuadratic functionRational functionAlgebraic function Polynomial function Cubic function etc. and many moreThe value of f can be calculated by using formula
fx = 4 - x2
f(4) = 4 - 4 x 2

Which object made of one or more smaller units would make the best model of a group of cells from a plant?
An object that is made of one or smaller units would make the best model of a group of cells from a plant is a sponge. The correct option is B.
What are cells?All living things, from microbes to people, rely on cells for structure and function. Scientists regard them as the tiniest form of life. Cells contain the biological machinery that produces the proteins, chemicals, and signals that are responsible for everything that occurs within our bodies.
The cellular level is the most fundamental level of organization. A cell is the fundamental unit of life and the smallest reproducible unit. While the form and function of cells vary widely depending on the organism, all cells share a few characteristics.
Cells combine to form tissues, and tissues combine to make organs. Organ systems, such as the skeletal and muscular systems, are made up of organs.
Therefore, the correct option is B. sponge.

When _____________ light strikes an object, the _____________ of the object depends on how the object _____________ and/or _______________ the colors of light.
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.
