Melting point, is the temperature at which the solid and liquid forms of a pure substance can exist in equilibrium. As heat is applied to a solid, its temperature will increase until the melting point is reached. More heat then will convert the solid into a liquid with no temperature change.

Answer:
57.6g
Explanation:
So, if in one mole of water, 16 g of oxygen atom is present. Then, in 3.6 moles of water, the mass of oxygen present will be 3.6×16=57.6g. Therefore, the amount of oxygen present in 3.6 g water is option (B)- 57.6 g.
Answer:
See explanation
Explanation:
11/5 represents the mass number and the number of protons that boron has. 11 means that the total mass number, or the combined number of protons and neutrons is 11, while the 5 represents the number of protons. This means that the isotope must have 11-5=6 neutrons. Hope this helps!
The primary structure of DNA can be broken in two parts: 1) the backbone of the molecule and 2) the bases, which are the side chains. The backbone of DNA is made up of alternating sugar (deoxyribose) and phosphate groups as seen below: sugar-phosphate-sugar-phosphate-sugar-phosphate
