Answer the following question given this paragraph: Ionic bonds are possible because the elements involved have either donated or accepted one or more electrons. Sodium chloride is formed when each sodium atom donates its single valence electron to a chlorine atom. As a result, both ions have a noble gas configuration, and an attraction is formed between the positive sodium ions and the negative chloride ions. Q: What is formed when each sodium atom donates its single valence electron to a chlorine atom? Choices: - carbon chloride - nitrogen chloride - trioxide chloride - sodium chloride A:
sodium chloride
Answer the following question given this paragraph: People have known about gravity for thousands of years. After all, they constantly experienced gravity in their daily lives. They knew that things always fall toward the ground. However, it wasn't until Sir Isaac Newton developed his law of gravity in the late 1600s that people really began to understand gravity. Newton is pictured in Figure below . Q: What did sir isaac newton's famous law help people understand? Choices: - radio waves - light - motion - gravity A:
gravity
Q: Answer the following question given this paragraph: The brain and spinal cord are protected within bones of the skeletal system, but injuries to these organs still occur. With mild injuries, there may be no lasting effects. With severe injuries, there may be permanent disability or even death. Q: Bones are part of which body system? Choices: - hard system - circulation system - muscular system - skeletal system A:
A: skeletal system
Question: Answer the following question given this paragraph: The major component of a solution is called the solvent. The minor component of a solution is called the solute. By major and minor we mean whichever component has the greater presence by mass or by moles. Sometimes this becomes confusing, especially with substances with very different molar masses. However, here we will confine the discussion to solutions for which the major component and the minor component are obvious. Solutions exist for every possible phase of the solute and the solvent. Salt water, for example, is a solution of solid NaCl in liquid water; soda water is a solution of gaseous CO2 in liquid water, while air is a solution of a gaseous solute (O2) in a gaseous solvent (N2). In all cases, however, the overall phase of the solution is the same phase as the solvent. Q: The major component of a solution is called what? Choices: - solute - mixture - water - solvent A:
Answer: solvent

(Q).
Answer the following question given this paragraph: The mouth is the first digestive organ that food enters. The sight, smell, or taste of food stimulates the release of saliva and digestive enzymes by salivary glands inside the mouth. Saliva wets the food, which makes it easier to break up and swallow. The enzyme amylase in saliva begins the chemical digestion of starches to sugars. Q: What is the first digestive organ that food enters? Choices: - stomach - tongue - esophagus - mouth A:
(A).
mouth
