Carbon Dioxide + Water ---> Glucose + Oxygen.

Pressure = Force ÷ Area

Joules

Four groups on the periodic table are, groups of alkali metals, alkaline earth metals, halogens, and noble gases. 

The gas particles collide which makes gas pressure.

N

Au

Fe

Cu

mass of (substance) = e.g 0.24g

mass of (product) = e.g 0.80g

(substance + oxygen  --->  2 together)

e.g - magnesium + oxygen ---> magnesium oxide 

                      0.24g                                0.80g

0.80g - 0.24g = 0.56g 

A force can be a push or pull.

Contact Forces, e.g = Friction, Air Resistance and Upthrust.

Non-Contact Forces, e.g = Gravity.

Carbs - provide energy.

Lipids (fats) - provide energy.

Proteins - growth and repair.

Vitamins - healthy.

Minerals - healthy. 

Fibre - (not a nutrient but lets food move through body easily. 

Starch - Iodine, if startch is there it will go blue/black.

Lipids - Filter paper, rub against food and if will go translucent if lipids are there.

Sugar - Benedicts solution, makes the food go orange if sugar is there.

Protein - Copper sulfate, makes the food go purple if protein is there. 

They contain chlorophyll. 

Allows gases to diffuse in and out of the leaf.

Glucose + oxygen ---> carbon dioxide + water.

Glucose ---> Lactic Acid.

Metals usually have high melting points. 

Non-Metals have low boiling points.
