Sorry if I'm wrong but it's 1) learner engages in scientifically oriented questions. 2) learner gives priority to evidence in responding to questions. 3) learners formulate explanations from evidence. 4) learner connects explanations to scientific knowledge. 5) learner communicates explanations.
Answer:
Check the explanation
Explanation:
functional group found in the major organic product = alpha -beta unsaturated ketone
Reaction used to form this functional group = Michael condensation reaction
Also other reactions are - Aldol condensation , Robinson annulation reaction.
Kindly check the attached image below to see the step by step solution to the question above.
Of the six commonly recycled plastics, four can withstand temperatures of 100 degrees Celsius (212 degrees Fahrenheit) or above. According to Machinist Materials, polyethylene terephthalate -- PET, or recyclable 1 -- has a melting point of 255 degrees Celsius (491 degrees Fahrenheit).
Explanation:
An observation is defined as the process which explains how it is happening (qualitative) and and quantitatively able to measure something about the process.
A law is defined as a verified statement that will remain true under the mentioned circumstances as it is based on the past observations that are carefully tested.
A theory is defined as the explanation of an aspect of natural world that can be tested, modified or rejected as a result of further experiments.
Hence, the given statements are classified as follows.
(a) All matter is made of tiny, indestructible particles called atoms - Theory
(b) When iron rusts in a closed container, the mass of the container and its contents does not change - Observation
(c) In chemical reactions, matter is neither created nor destroyed - Law
(d) When a match burns, heat is evolve - Observation
