well its evaporation cuz it the suns heat heated the ice to the point where it turned to a gas, it could be conduction cuz the heat of the sunshine conducted the ice and turned it to a gas but that would be evaporation too so its not onduction, its not a chemical change cuz theres no new molecule the substance is itself, and its not a sudden change obviously
so the answer is A. evaporation~~~
Answer:
Calcium
Explanation:
Clacium has atomic number 20. The atomic number. This means that it has 20 protons and 20 electrons. it has 21 neutrons.
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.
Hydrogen is the smallest chemical element because it consists of only one proton in its nucleus. Its symbol is H, and its atomic number is 1 .It has an average atomic weight of 1.0079 amu, making it the lightest element.
a.1.00784 u
b.Atomic-36
Kr
Krypton
Atomic Weight. 83.80
That means that there must be a balance between the positively charged protons and the negatively charged electrons. Atoms must have equal numbers of protons and electrons. In our example, an atom of krypton must contain 36 electrons since it contains 36 protons. Electrons are arranged around atoms in a special way.
