The answer to you're question is:
~A. Lunar eclipse occurs when the Moon passes directly behind Earth and into its shadow. This can occur only when the Sun, Earth, and Moon are exactly or very closely aligned with Earth between the other two. A lunar eclipse can occur only on the night of a full moon.
Hope this helps!!!
ANSWER:
in words equations we use words to show what happens using words a chemical reaction.
Answer:
1.33 kilograms of this liquid must be evaporated to freeze a tray of water at 0°C to ice at 0°C.
Explanation:
Let the mass of liquefied dichlorodifluoromethane be x.
Mass of water to freeze = 571 g
Moles of water =
Heat of fusion of ice = 6.02 kJ/mol
Heat lost when 1 mole of water freeze's = -6.02kJ/mol
Heat lost when 31.7 moles of water freeze's: Q
Heat required to evaporate x amount of liquefied dichlorodifluoromethane: Q'
Q'= -(Q) = 191. kJ
Moles of liquefied dichlorodifluoromethane =
Heat of vaporization of dichlorodifluoromethane = 17.4 kJ/mol
Solving for x:
x = 1328.2 g = 1.33 kg
1 g = 0.001 kg
1.33 kilograms of this liquid must be evaporated to freeze a tray of water at 0°C to ice at 0°C.
An anchoring phenomenon anchors all of the learning within a unit. So, it is a unit level event that the classroom is trying to make sense of as they engage in a series of lessons.
Since the questions the students ask about the anchor drive the learning within the unit, the anchor should be complex and require an understanding of several big science ideas to explain.
At strategic moments, the class revisits the anchoring phenomenon to review their initial questions to see which they have answered, which they are making progress on, and what new questions they may have to help us continue learning about the phenomenon.
Throughout the unit, the classroom and each student should be given opportunities to share their thinking and how it relates to the anchoring phenomenon.
YOU SHOULD PUT IT IN YOUR OWN WORDS THOUGH <3
Answer:
Since energy can’t be created or destroyed, and water loses potential energy when it freezes to form ice. The energy remains electrical but then changes to kinetic when Enough energy is released.
