Assignment Summary For this assignment, you will construct a scientific model of the water cycle to show how water is recycled through an ecosystem. Once you have drawn your model on a poster board, you will write one to two paragraphs explaining how water is transferred within and between organisms and the environment. Background Information Water is a very important compound. Organisms need water to carry out life-maintaining processes such as growth and development. Without water, living things will not survive. Water continually flows among the atmosphere, land, water, and living organisms. This process, called the water cycle, allows water to be recycled as it moves through Earth’s spheres. Materials Assignment Instructions Step 1: For this project, you are expected to submit the following: 1. Your model of the water cycle 2. One to two typewritten paragraphs describing the water cycle Step 2: Prepare for the project. a) Read through the guide before you begin so you know the expectations of this project. Pay particular attention to the instructions you need to follow to create a model on your poster board. b) If anything is not clear to you, be sure to ask your teacher. Step 3: Gather materials for the model. a) Start with a blank poster board. Be sure to put your name on it. b) You may either draw the parts of the water cycle or print images to construct a model on your poster board. Gather any drawing tools that you will need, or print any images you want to use. Step 4: Create a model of the water cycle. a) Your model should include bodies of water such as lakes and oceans, organisms, air, and land. b) Draw arrows indicating how water moves within an ecosystem and between organisms and their environment. Be sure to include the Sun and gravity in your model. c) Include short phrases on your poster that summarize what occurs at each stage of the water cycle. Large poster board Markers, crayons, or colored pencils Scissors Glue or tape Student Guide (continued) Step 5: Write a paragraph describing the water cycle. a) Type one to two paragraphs describing the full water cycle. Be sure to use full sentences and proper grammar.
Answer:
the water cycle is a system that goes through evaporation then the water goes into the clouds and rains down as preparation

Which of the following redox conditions will produce a spontaneous reaction?
A. The voltage of the reduction half-reaction is negative.
B. The voltage of the reduction half-reaction is positive.
C. The sum of the voltages of the half-reactions is negative.
D. The sum of the voltages of the half-reactions is positive.
Answer:
D. The sum of the voltages of the half reactions is positive.
Explanation:
It's correct on apeex
The statement, that describes the redox conditions will produce a spontaneous reaction is "the sum of the voltages of the half-reactions is positive."
What is spontaneous reaction?A spontaneous reaction is one that favors the creation of products under the conditions of the reaction. It can move in a specific direction without being propelled by an external source of energy. If the standard electrode potential for the redox reaction is positive, the reaction is spontaneous.
If [tex]E^{0}[/tex] (redox reaction) is positive, the reaction will move onward (spontaneous). The redox conditions will cause a spontaneous reaction, and the sum of the half-reaction voltages is positive. Hence the correct option is D.

A coffee cup calorimeter contains 153.21 g of water at 22.50 °C. A 65.454 g piece of iron is heated to 101.62 °C. The piece of iron is added to the coffee cup caloriemter and the contents reach thermal equilibrium at 25.68 °C. The specific heat capacity of iron is 0.449 Jg·K and the specific heat capacity of water is 4.184 Jg·K. How much heat, , is lost by the piece of iron?
Answer:
Q = 2232J
Explanation:
In the system, the energy that is lost by the iron is:
Q = S*ΔT*m
Where Q is heat, S is specific heat of iron ΔT is change in temperature and m is mass of the piece of iron.
S = 0.449J/gK
ΔT = 101.62°C - 25.68°C = 75.94°C
m = 65.454g
Q = 0.449J/gK*75.94°C*65.454g
Q = 2232J

Explanation:
How many moles of carbon are there in 5 g of carbon?
Answer:
0.416666667
Explanation:
number of moles= mass of sample ÷ molar mass
=5÷12
=0.41666667
The number of moles of carbon are there in 5 gram of carbon is 0.41 moles.
How do we calculate moles from mass?Moles of any substance will be calculated by using the mass by following the below equation:
n = W/M, where
W = given mass of carbon = 5g
M = molar mass of carbon = 12g/mol
On putting values, we get
n = 5 / 12 = 0.41 moles
Hence required moles of carbon is 0.41 moles.

How do magnetic stripes show the history of Earth's magnetic field?
A. As you move away from an ocean ridge, the rocks get older.
B. As you move away from a coast, the rocks get younger.
C. As you move down through the seafloor, rocks get older.
D. As you move eastward along a continent, rocks get older.
The way that magnetic stripes show the history of the Earth's magnetic field is A. As you move away from an ocean ridge, the rocks get older.
What do magnetic strips show of Earth's history ?By looking at how our planet's magnetic field changes throughout time, scientists may estimate the age of the seafloor. A geomagnetic reversal is the periodic reversal of the currents in the liquid core that generate the Earth's magnetic field. Throughout Earth's history, this has occurred frequently.
When researchers examined the seafloor's magnetic characteristics, they found normal and reversed magnetic stripes of varying widths. These magnetic patterns are symmetrical on both sides and parallel to the mid-ocean ridges.
Away from midocean ridges, they observed that the age of the bottom became progressively older.

Substance 2 has a stronger molecular attraction.
What are solids?Solid is one of the four fundamental states of matter. The molecules in a solid are closely packed together and contain the least amount of kinetic energy. A solid is characterized by structural rigidity and resistance to a force applied to the surface.
Both solids are supplied with an equal amount of energy. Out of both substances, substance 2 has a stronger molecular attraction due to which it can not easily change into a liquid while substance 1 has a lesser molecular attraction so supplying of few amounts of heat will change substance 1 into a liquid state.
Hence, Substance 2 has a stronger molecular attraction.
