A compound comprises the same proportion of its components, a mixture can be made up of varying amounts.A compound may have physical and chemical properties which are quite different to those of any of its components. A mixture retains many of the physical and chemical properties of its main ingredient.

how did ancient Egyptian life differ from ours
how did Manteo and Wanchese differ in their views of the English settlers
Elements consist of atoms which all have the same atomic number, chemical compounds consist of 2 or more different elements chemically bonded togetherElements cannot be broken down into anything simpler. Compound are made up of more than one element joined together.

The rates of mechanical weathering does not affect anything since the chemical properties remain unchanged. Only chemical weathering affects the chemical properties of an object.
Rates start at 69% and higher .
Chemical weathering processes change the mineral composition of the rock, but physical weathering processes do not. Mechanical (physical) weathering is the breakdown of rock into smaller particles due to such factors as freezing and thawing, release of pressure, water absorption salt crystal formation, landmass uplift, expansion and contraction from the sun or fire, plant root growth, actions of animals, abrasion, or other means that do not directly affect the rock's chemistry. Chemical weathering is the dissolution, carbonation, oxidation, or hydrolysis of rock and mineral by chemical means only, mostly from reactions with water or the acids contained in rainwater. Other materials are formed in the process. Warm, tropical climates are ideal environments for chemical weathering to take place as the chemical reactions are quickened by the bountiful rain and warm temperatures.
They contain different combinations of particles.
During a chemical reaction, the bonds between the atoms of the reactants break, and new bonds form to make the products.
Yes,physical change is different in chemical change because chemical change form a new substances or product that may arise into two substances held in chemical change
Salivary Amylase helps digest starch while in the mouth as a chemical digestion. Chewing is another form of digestion, but its mechanical
Weathering can break away less resistant parts of the rock and leave behind the more resistant parts.
