Answer the following question given this paragraph: Suppose that you wanted to know how many hydrogen atoms were in a mole of water molecules. First, you would need to know the chemical formula for water, which is H 2 O. There are two atoms of hydrogen in each molecule of water. How many atoms of hydrogen would there be in two water molecules? There would be 2 2 = 4 hydrogen atoms. How about in a dozen? In that case a dozen is 12 so 12 2 = 24 hydrogen atoms in a dozen water molecules. To get the answers, (4 and 24) you had to multiply the given number of molecules by two atoms of hydrogen per molecule. So to find the number of hydrogen atoms in a mole of water molecules, the problem could be solved using conversion factors. Q: H2o is the chemical formula for what? Choices: - glass - smog - salt - water A:
water
Q: Answer the following question given this paragraph: Saturn's largest moon, Titan, is about one and a half times the size of Earth's moon. Titan is even larger than the planet Mercury. The picture below compares the size of Titan to Earth ( Figure below ). Scientists are very interested in Titan. The moon has an atmosphere that is thought to be like Earth's first atmosphere with nitrogen and methane. This atmosphere was around before life developed on Earth. Like Jupiter's moon, Europa, Titan may have a layer of liquid water under a layer of ice. Scientists now think that there are lakes on Titan's surface. Don't take a dip, though. These lakes contain liquid methane and ethane instead of water! Methane and ethane are compounds found in natural gas. Q: Europa and titan are names of what kind of celestial objects? Choices: - galaxies - stars - asteroids - moons A:
A: moons
Question: Answer the following question given this paragraph: The ability to see is called vision. The brain and eyes work together to allow us to see. The eyes collect and focus visible light and change it to electrical signals that travel to the brain. The brain interprets the signals and "tells" us what we are seeing. Q: What are the organs work together to allow us to see? Choices: - lungs - heart - nose - brain and eyes A:
Answer: brain and eyes
