Answer:
40 g
Explanation:
Find the line labeled KClO3 (which might take you a min, theres a lot of lines here)
Notice that when the line creates a direct point, you can measure the exact temperature needed to dissolve a certain amount (like how they gave 30 degrees and it lined up perfectly with the 10 g line. )
Since its asking for the amount at 80 degrees, all you need to do is trace the line to the 80 degree point, and look at the grams. (notice it made a direct point, so there definitely should be any decimals or guesswork)
By reading the graph, you can tell that at 80 degrees, it dissolves 40 grams, and that is your answer.
Hope this helps :)
Answer:
carbon molecules share their 4 valence electrons through single, double, and triple bonds.
Explanation:
I think you meant ionic bonds not lonic bonds
1. Color changes.
The Statue of Liberty, though known for its green color, was originally covered in a layer of copper. After a redox (reduction-oxidation reaction) the color changed due to a chemical change.
2. Gas Production
3. Light Produced
Light sticks work as the result of a chemical reaction between hydrogen peroxide and phenol oxalate ester.
4. Temperature Changes
5. Volume Change
The two substances have different densities. Density can be affected by the temperature of a substance. Since they have to same volume but weigh differently, they have different densities. Remember, density = mass/volume
Answer:
Altitude is an anagram of latitude. Latitude is an anagram of altitude.
Explanation:
As nouns the difference between latitude and altitude is that latitude is (geography|astronomy) the angular distance north or south from a planet's equator, measured along the meridian of that particular point while altitude is the height measured from sea level up to any given point.
