Ques: Answer the following question given this paragraph: Carbohydrates are the most common type of organic compound. A carbohydrate is an organic compound such as sugar or starch, and is used to store energy. Like most organic compounds, carbohydrates are built of small, repeating units that form bonds with each other to make a larger molecule. In the case of carbohydrates, the small repeating units are called monosaccharides. Q: What is the most common type of organic compound? Choices: - lipids - hydrocarbons - proteins - carbohydrates A:
Ans: carbohydrates

Ques: Answer the following question given this paragraph: Which of the following is matter and not matter? 1. the moon 2. an idea for a new invention Answer 1. The moon is matter. The invention itself may be matter, but the idea for it is not. To understand matter and how it changes, we need to be able to describe matter. There are two basic ways to describe matter: physical properties and chemical properties. Physical properties are characteristics that describe matter as it exists. Some of many physical characteristics of matter are shape, color, size, and temperature. An important physical property. Q: Physical properties are characteristics that describe what as it exists? Choices: - imagination - antimatter - life - matter A:
Ans: matter

Ques: Answer the following question given this paragraph: Valence electrons of both atoms are always involved when those two atoms come together to form a chemical bond. Chemical bonds are the basis for how elements combine with one another to form compounds. When these chemical bonds form, atoms of some elements have a greater ability to attract the valence electrons involved in the bond than other elements. Electronegativity is a measure of the ability of an atom to attract shared electrons when the atom is part of a compound. Electronegativity differs from electron affinity because electron affinity is a measure of the actual energy released when an atom gains an electron. In contrast, electronegativity is a relative scale, so it is not measured in units of energy. All elements are compared to one another, and the most electronegative element, fluorine, is assigned an electronegativity value of 3.98. Fluorine attracts shared electrons better than any other element. Figure below shows the electronegativity values of most elements. Q: What does fluorine attract better than any other element? Choices: - ionic bonds - electron shells - magnets - shared electrons A:
Ans: shared electrons

Ques: Answer the following question given this paragraph: Groundwater dissolves minerals and rocks into ions. Groundwater deposits those ions into different types of structures. Limestone caves are the best place to see these structures. Water erodes the cave and it has deposits structures like stalactites and stalagmites. The cave pictured here is Carlsbad Caverns in New Mexico. Q: Groundwater dissolves minerals and rocks into what? Choices: - gravel - sand - grit - ions A:
Ans:
ions
