Chemistry Of Life

How does the protein that you eat wind up building your muscles?

 It makes up your skin, muscle , and bones. The protein spreads around your body through blood cells. Decomposition is when your body breaks apart the protein particles. Synthesis  is when the protein particles

spread apart around the body and go to where the body needs the muscle.  

  

 How does that bowl of pasta give you energy?

Because it has carbohydrates.

the polymer starch breaks apart to create energy (ATP).

 Why do we need to eat fat?

Fat protects the body from getting damaged. It makes our bodies stronger. 

its always good to have fats in your body just not a lot especially of the bad fats such as Butter, and oils. 

THE FATS 
Triglycerides are one of the fats stores energy and insulates, cushions and protects. 
Phospholipids are modified Triglycerides.
Cholesterol is animal membranes and synthesizes hormones.
  

Periodic Table

In class we learned about the periodic table and this is what I leaned, 

Organization of table 

• Yellow is most reactive metals 
• react in  water to release H2 gas

•  valence electrons in the outermost energy level groups. 
• elements in any group of the periodic table have similar physical and chemical properties. 
• the group provides information about the number of valence electrons. 
• Halogens are the right side of the chart are non metals they easily combine with other metals.
• Alkinal Metals are on the left side and are metals they react in water and can not be mixed   

 Parts of table

The rows on a periodic table are called periods going horizontal 

the vertical column are named  families.

Trends 

• Radius gets larger . left to right 

• The peaks of the chart are the most reactive metals 

Flame Test Lab Questions

1. Errors that can appear well using the flame test. Scientist could mistakenly read the name of the chemical wrong and say the wrong colors. 

2. You need more than one property to find the answer to a substance.

3. the colors in the flames are produced from the type of substance if the substance is a high the color will be blue, red etc. if the substance slow then the color will be yellow, orange.

4. Mn, Sr, Cn, Co, Mg, Ba, Li

5. The element has to be heated by the flame before it can show color because the heat gives the element power and makes the electrons exited making them jumpy which creates light.
