(Solids, Liquids, and Gasses.)
What is a solid?
We all know H2O is water, well I hope you know. Both elements needed to make water are also both naturally gasses. But how many Hydrogen atoms are needed to make H2O?
What are 2 Hydrogen atoms?
What's made with a chemical reaction?
What is a Product?
This Alkali Metal (element), located in family one is known for being in things like avocado, spinach, and is mostly know for being in bananas, But this Element on it's own is highly reactive, and is not safe to eat!
Potassium (K)
Science State Middle School is doing a competition where students are divided into different families of the periodic table, and later have to make a reaction with an element located in their family. Bill is a student at this school, and missed a day due to him needing to go to the optometrist, so he gets to pick which family he wants to go into. Bill failed his chemistry test, and honestly wants to instead see a cool explosion happen instead, what family should Bill choose if he wants to create a huge reaction? (Two acceptable answers, only one is needed)
What is Family 1 (Or 1A)?
This state of matter fills all available space, and doesn't have a definite shape, nor volume!
What is a Gas
In an E-dot Diagram for an element, the surrounding dots show the valence electrons (ve-) of an element. If an element was in the 5th Family, how many Valence electrons (dots) would there be?
Connor was busy listening to music during class, so he couldn't hear his teacher talking. When he finally listened, however he only noticed two molecules on the board N2 + H2 He saw his teacher write on the side NH3 So he wrote that down for his answer without waiting for his teacher to finish. What law did Connor just break?
Law of Convervation of Motion/Mass
Known for being expensive and its high relevance in jewelry, this Inner transitional metal is perfect for things like rings and necklaces. When the Olympics made medals with a large about this Element present, winners used to bite them to test for authenticity, since it's naturally very soft and often made into an alloy to increase it's strength.
Gold (Au)
Neal loves chemistry. He loved space after watching a bunch of movies so he had an old model of a solar system he transformed into a model of an atom and it's valence electrons surrounding the nucleus. Sadly for Neal, this model was wildly inaccurate. If the nucleus he used for the model was around the size that a blueberry was, how far away should the valence electrons have been?
About a football stadium away (Will accept close enough answers)
When a liquid reaches their boiling point they start to well... boil! But it's similar to evaporation, so what's the difference between the two? (You do not have to phrase this like a question)
Evaporation happens only at the surface of a liquid, and boiling happens both below and at the surface of a liquid,
Hydrogen is a freak with only one valence electron, and even though it's stable, it's also highly reactive! What would you call it if a Hydrogen atom bonded with a Chlorine atom? (Type of BOND)
What is a Covalent Bond?
If I wanted to make NH3 , and I had an access to infinite amounts of N2 and H2 (Nitrogen and Hydrogen gas) how many molecules of each minimum would I need to get some NH3? (answer can result in multiple molecules of NH3 but just the minimum amount needed.)
one molecule of N2 and three molecules of H2
This Noble gas is known for shining bright and lighting up signs in bright colors! Highlighters are often described as being "blank" colored
Neon! (Ne)
Mason likes to make things with different elements in a lab, unfortunately for Mason, he started a fire while trying to light a candle (DON'T DO THIS IN A LAB), but when he tried to put it out with water it didn't extinguish it, what's an explanation on why water didn't work? (multiple answers)
2. The fuel for the fire was lighter than the water
3. The fire was hot enough to evaporate the water,
Dry ice is a great example of sublimation, where a solid doesn't pass through a liquid state. Dry ice is really just solid carbon dioxide, but why can't it just be a normal liquid when it melts?
It cannot exist as a liquid due to normal atmospheric pressure.
Fool's gold, otherwise known as pyrite, is known for resembling gold. But while gold is $33,000-$66,000 per pound, pyrite can land you about $2-$50 it's chemical equation is FeS2 how many atoms are there per molecule of pyrite?
What are 3 atoms?
The statue of liberty is known for a lot of things, one of which is it's nice green color. But it was originally a nice dull orangey-color. It's made of many elements, one of which is copper which reacts with the oxygen in the air. What kind of reaction occurred with the Statue of Liberty?
Oxidization
This Element that turned out to be highly poisonous and toxic was used in a variety of things ranging from paints and dyes to treatments for medical conditions! Fun fact: It's known as the "king of poisons" due to its use for... seasoning a king's food.
What is Arsenic (As)?
Alex really likes to write. He writes on almost anything and everything he can think of. Today, he was writing a story about a scientist named Aaron. Aaron was doing a report on the chemical compound of MgCl2. After writing it, he forgot how to spell it! He knows that the negative ion is a single element, so is it magnesium chloride or magnesium chlorite?
Magnesium Chloride
When magma cools down, some of the material crystallizes! While not everything turns out to be a crystal, an example being obsidian, magma still contains crystals! If this crystalline solid was heated up, though not as much as lava would be, the "magma" would instead be very safe to consume liquid found covering 71% of the earth.
What is Ice?
Mix salt (NaCl) with water, you get a dehydrating drink! but, mix it's components (Na/Cl), you get an explosion and some disinfectant. what kind of reaction just occurred if we mixed one of its components and water together to make a combined substance?
What is Synthesis?
This Element is Radioactive and named after a prominent scientist who worked with various radioactive elements, and later died after long and repeated exposure. This Element is NOT naturally occurring. It's also used in Satellites and planetary rovers!
Curium (Cm)
Steve runs a convenience store and they get a lot of shipments for things that need to stay cold. To keep things cold, there are large freezers and fridges in the back of the store. They're made out of stainless steel! It's a nice strong alloy that doesn't rust! Name some of the elements that make up stainless steel. (only requires 2 elements for an answer, but you may include others)
Iron, chromium, nickel, carbon, molybdenum, silicon (note, it can. also be made with other types of metals)
