There is no diagram attached but there are some ways by which you can find it too easily by yourself
Usually energy diagram uses ∆H .
So
- If ∆H is +ve means reaction is exothermic and energy is released
- If ∆H is -ve means reaction is endothermic and energy is absorbed
So observe∆H whether it. is decreasing or increasing ,
- If increasing then energy is being released and vice versa
When is the principle of conservation of mass true?
B. Only for reactions that take place in closed systems.
Hope this answers your question!
Answer:
distance velocity displacement, all three
Explanation:
Rare earth metals are a group of 17 elements - lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, scandium, yttrium - that appear in low concentrations in the ground
Condensation polymerization : releasing water as by product, occurs in monomer that has functional group that can react with each other e.g alcohol&carboxlic acid to form polyesters, carboxylic acid and amines to form polyamides,etc.
Radical Polymerization: occurs by propagating radical monomers or monomer that has unsaturated bonds, such as ethene, initiated by formation of radical from the monomer by using uv lights/other initiator, does not produce any by products
