Iron filings can be attracted by the magnet whereas salt can not. So the mixture can be separated by a magnet
C: 12.0107 g/mol ≅ 12.00 g/mol
H: 1.00784 g/mol ≅ 1.008 g/mol
O: 15.999 g/mol ≅ 16.00 g/mol
n(molar mass of CH2O)= 180
n.30=180
n=6
molecular formula: c6h12o6 glucose
Answer:
Extensive Properties
Explanation:
A physical property that will change if the amount of matter changes. Change in which the matter's physical appearance is altered, but composition remains unchanged. Solid is distinguished by a fixed structure. Its shape and volume do not change.
D. They act on a specific type of substrate in a reaction
Hope this helps!
Answer: option B) They provide an alternate lower energy mechanism by which the reaction proceeds
Explanation:
Catalyst are involved in chemical reaction increasing the rate they occur by lowering the activation energy found in the bound- reactants complex.
The reaction moves forward because the lower energy mechanism when catalyst are added allows for a more easily splitted bond, thus, allowing the formation of products.
