Q: Answer the following question given this paragraph: Summary Each atom of an element contains the same number of protons, which is theatomic number (Z). Neutral atoms have the same number of electrons and protons. Atoms of an element that contain different numbers of neutrons are calledisotopes. Each isotope of a given element has the same atomic number but a different mass number (A), which is the sum of the numbers of protons and neutrons. The relative masses of atoms are reported using the atomic mass unit(amu), which is defined as one-twelfth of the mass of one atom of carbon-12, with 6 protons, 6 neutrons, and 6 electrons. The atomic mass of an element is the weighted average of the masses of the naturally occurring isotopes. When one or more electrons are added to or removed from an atom or molecule, a charged particle called an ion is produced, whose charge is indicated by a superscript after the symbol. Q: What do neutral atoms have the same number of? A:

OPTIONS:
- toxins and protons
- gases and protons
- Measure and electrons
- electrons and protons

A: electrons and protons

input: OPTIONS:
- 32 degrees
- 100 degrees
- absolute zero
- zero degrees Now, answer this question: Answer the following question given this paragraph: A: If calcium chloride dissolves in water, it breaks down into its ions (Ca 2+ and Cl - ). When water has ions dissolved in it, it has a lower freezing point. Pure water freezes at 0C. With calcium and chloride ions dissolved in it, it won't freeze unless the temperature reaches -29C or lower. Q: In celsius, what is the temperature at which water freezes? A:
A:
output: zero degrees

Answer the following question given this paragraph: Gravity is traditionally defined as a force of attraction between two masses. Weight measures the force of gravity and is expressed in newtons (N). Q: What is the force of attraction between two masses? A:

OPTIONS:
- electricity
- inertia
- momentum
- gravity

Answer: gravity

Problem: OPTIONS:
- Prime Meridian
- orbital
- pole
- equator
Q: Answer the following question given this paragraph: Lines of latitude circle around Earth. The equator is a line of latitude right in the middle of the planet. The equator is an equal distance from both the North and South Pole. If you know your latitude, you know how far you are north or south of the equator. Q: What term is used to describe the line of latitude right in the middle of the planet? A:
Answer: equator

Problem:OPTIONS:
- alteration satellite
- flagella satellite
- high orbit satellite
- manmade satellite

Answer the following question given this paragraph: We commonly talk about satellites orbiting Earth. But what does that really mean? When a satellite, space shuttle, or some other object is orbiting a planet, it maintains a circular orbit around the planet a constant distance off the surface. Manmade satellites typically orbit between 200 and 400 miles. For example, the International Space Station (ISS) orbits at 370 km, or 230 miles. Q: Orbiting at a fairly typical 370 kilometers, the international space station is an example of what? A:
****
A: manmade satellite

Problem:OPTIONS:
- Spinner
- plasma
- electrode
- cathode

Answer the following question given this paragraph: The standard reduction potential can be determined by subtracting the standard reduction potential for the reaction occurring at the anode from the standard reduction potential for the reaction occurring at the cathode. The minus sign is necessary because oxidation is the reverse of reduction. Ecell = Ecathode Eanode +0.34 V = E 2+ EH + /H = E 2+ 0 = E Cu. Q: The standard reduction potential can be determined by subtracting the standard reduction potential for the reaction occurring at the anode from the standard reduction potential for the reaction occurring at this? A:
****
A:
cathode
