<u>Answer: </u>
Phases of moon:
- New Moon
- crescent Moon
- First-quarter Moon
- gibbous Moon
- full Moon
<u>Explanation:</u>
The lunar cycle has 8 phases. The first phase is new moon. New moon is seen while the moon lies between the sun and the earth. After few days occurs the crescent moon when the moon travels towards its east. The next phase is first-quarter phase. During this phase half of the moon will be illuminated. The fourth phase is waxing gibbous moon phase where waxing refers to 'growing larger' and gibbous means 'shape' hence waxing gibbous refers to growing shape. Next is the full moon phase. This happens when the moon and the sun comes on the opposite sides of our earth. The next phase will be waning gibbous moon where the moon decreases in size. This phase is followed by third quarter and finally the waning crescent moon phase.
As water freezes its molecules move farther apart. As when water freezes , Its move farther apart .
And the cause of this movement is hydrogen bond that is formed among the surrounding water molecules that causes water molecules to move apart. So as water freezes its molecules move farther apart, it is the correct answer .
Answer:
37
Cl
17
(37 is a superscript to the left of the symbol, and 17 is a subscript to the left of the symbol)
Explanation:
1) Chlorine-37 is the chlorine isotope with mass number 37.
2) The atomic mass of chlorine is 17. All the atoms of chlorine have the same atomic number (all the atoms of an element have the same atomic number). You find this number in a periodic table.
3) The isotope representation consists of:
i) The symbol of the element (Cl in this case) at the center of the representation.
ii) The mass number (37) as a superscript to the left of the symbol. That is:
37
Cl
iii) The atomic number (17) as a subscript to the left of the symbol. That completes the representation in this form:
37
Cl
17
