chemistry test Friday!

5/25/2022

It was a busy day of class pictures. Students had a chance to work on their novel studies and we completed to book club meetings. Students also worked on their French projects and in the afternoon worked on their digital art and had a high school presentation and music class.

1.) NOVEL APPROACH:

Stick to you reading and workbook schedule
Group 3 and 4 meet tomorrow

2.) MATH: No Hwk.

3.) SCIENCE TEST FRIDAY: Be sure to study the vocabulary and review the learning intentions.

4.) FRENCH:

Pronunciation guide due Tomorrow
Project Due (Monday)

5.) POST A RESPONSE:

Make up five questions related to the science chemistry unit and post them here.
Answer the five questions posted by one of your classmates.
Reply original post giving feedback on the answers.

Dang, where’s everyone else?

Elton

1. according to their atomic number
2. helium is lighter than oxygen
3. a physical change doesn't change the chemical structure of a substance, but a chemical change does
4. the lower numbers are the strong acids and the higher numbers are the strong bases.
5. it is neutral because it does not have too much or lack hydrogen

Leah

1. Yes, and what kind of metal or non-metal it is.
2. Correct.
3. Also correct.
4. Yep. Pretty much.
5. Also because well, water is neither an acid or a base.

1. bob mixed a strange substance called HSbF6 with his juice.
is this a mixture or a solution or both?
2. not realizing that he had mixed the world's strongest acid with his juice, he took a gulp of the solution/mixture only to have his tongue burned right off.
is this a physical or chemical reaction?
3. after bob got out of the hospital, he compressed oxygen with an immense pressure and created liquid oxygen.
what state(s) of matter are missing?
4. after getting out of the hospital again due to inhaling too much oxygen, he was puzzled by the fact that balloons could float.
explain why.
5. because the HSbF6 was spilled on the floor when his tongue got burned, bob came home nothing but ashes.
is this chemical or physical.

Leah

5/25/2022 04:39:13 pm

1. Solution because the chemicals are all mixed together.
2. Chemical reaction and btw, this Bob guy is not smart.
3. Solid and plasma
4. The balloon had helium in it.
5. Chemical because the house is no more.

Do i have to take the test

Mr. Fisher

5/25/2022 05:08:51 pm

Let's chat tomorrow and see hat you missed.

Jasmine

5/25/2022 04:58:41 pm

1: What is the definition of a mixture
2: Where is bleach on the pH scale
3: What is neutral on the pH scale

1. a thing that is made up of mixing multiple different substances.

2. 10

3. 7

4. a substance that has ph values 0-6

5. By their atomic number and mass

Leah

5/25/2022 06:47:18 pm

Uh. . . I think for number 4, I think it’s the other way around.

Mr. Fisher

5/25/2022 05:08:06 pm

@Everyone- FYI There will be no pH questions on the test. Just the first 5 learning intentions. See yesterday' s post.

1. List the first 10 word work words for chemistry.

2. Steve chopped down a tree, then he burnt it into charcoal. Are these changes physical or chemical?

3. What kinds of matter are used to make stew?

4. Steve crafted an iron pickaxe out of iron and wood. Is this an element, a mixture, or a solution?

5. How are the element in the Periodic table arranged?

Emily

5/25/2022 05:48:45 pm

1. Solution, dissolve, matter, solute, molecule, alloy, solubility, particle, substance, dilute.
2. Chopping a tree is a physical change, while burning it into charcoal is a chemical change.
3. Solids, like vegetables and meat, and liquids, like water and stock.
4. A mixture.
5. By their properties.

Emily

5/25/2022 05:43:13 pm

1. If iron rusts, is that a physical or chemical change?
2. How do the particles in a solid, liquid, and gas look different? (in a diagram)
3. What is a compound? Give 3 examples.
4. What is the difference between a solution and a mixture?
5. Are all mixtures solutions?

Himavanth

5/25/2022 07:28:47 pm

Chemical. Tightly packed a bit distanced and far apart. A compound is a group of elements. The solute not being dissolved completely, and being completely dissolved. No.

Emily

5/25/2022 07:42:53 pm

1. correct
2. correct
3. a substance created by combining two or more elements, close
4. basically - or you could say that in a mixture, the two types of particles are not evenly mixed, and in a solution, the particles are evenly mixed
5. correct

Aliyah

5/25/2022 05:49:04 pm

1. What’s the difference between a mixture and solution
2. How do you know if something is a physical change
3. Is H2O a compound or element
4. What are two rules from particle theory
5. How is the periodic table organized

Sonia

5/25/2022 08:11:38 pm

A mixture can easily be separated, a solution can’t

The appearance changes, the chemical dna is still the same

Element

Heat makes stuff more attracted, everything is attracted to eachother

By their properties

Himavanth

5/26/2022 03:36:59 pm

3 is compound

Himavanth

5/25/2022 07:19:59 pm

@Mr.Fisher I wasn't here for particle theory.

Mr. Fisher

5/25/2022 07:31:44 pm

@Himavanth- I posted 3 videos on particle theory for you above.

Leah

5/25/2022 07:33:56 pm

Particle theory is like the study of particles in a solid, liquid, or gas. So like particles in a solid are tightly packed together. In a liquid, they are close and bump into each other. In a gas, they just move around everywhere.

Himavanth

5/25/2022 07:25:55 pm

What is the difference between element and compound?
What is the difference between mixture and solution?
Are you an element?
What is the most expensive element?
What is the most flammable element?

Leah

5/25/2022 07:35:05 pm

@MR. FISHER, BRING YOUR SPEAKER TOMORROW!!! ASAP!!!

LEAH

5/25/2022 07:35:37 pm

DON’T FORGET!

Mr. Fisher

5/25/2022 08:32:11 pm

@Leah- THANK YOU!! I am putting it in my back pack right now!

Leah

5/26/2022 08:23:50 am

Good.

Ian

1. give me an example of an acid
2. what are the 3 states of matter
3. is milk a solution or a mixture
4. if you cut paper, if it physical change or chemical
5. list the 5 rules from particle theory

Himavanth

5/25/2022 09:25:33 pm

Hydrochloric. Solid, liquid, gas, plasma. Mixture. Physical. Credit to brainly.com idk if its right : All matter is made of particles.

Particles have space between them.

Particles are always moving.

Particles move faster and get farther apart when heated.

Particles are attracted to each other

Sonia

1: What is a mixture
2: What is an element
3: What is neutral on the pH scale
4: What is a compound
5: How are the elements on the periodic table seperated?

Himavanth

5/25/2022 09:29:59 pm

Not chemically mixed substance. Pure substance. Substance with hydrogen and hydroxide ions. Chemically mixed elements. By their physical and chemical properties.

Kason

5/26/2022 07:28:07 am

1. A mixture can be easily separated.
2. It is a pure substance
3. Water/ 7
4. A compound is a thing that has two elements together.
5. By their properties.

hi mr fisher i can’t go to school tomorrow i will be doing my math test

Mr. Fisher

5/25/2022 09:31:50 pm

@Cindy- Okay thanks for letting me know.

Aaron

5/25/2022 09:16:01 pm

`1, what is a matter?
2, is milk a mixture? explain.
3, what is the difference between a compound and an element?
4,how many numbers are on a ph scale?
5, what would the particle of a compound look like?

Himavanth

5/25/2022 09:20:51 pm

Substance. Depends on the type. Elements are pure substances whereas compounds are made by mixing elements. 0-14. H20: 2 Hydrogen to 1 oxygen ratio.

Himavanth

5/25/2022 09:23:00 pm

Oops. Milk is a mixture.

1. What is matter?
2. Is oil mixture or solution? Why?
3. What is the difference between a compound and an elements
4. How is the periodic table managed?

1. how do things float?
2. if i burn something is it a chemical change?
3. is water a solution?
