Combine the following ions to create neutral compounds Y3+ and OH-
Answers
Answer:
Y(OH)₃
Explanation:
Given ions:
Y³⁺ OH⁻
To find a neutral compound that conforms with the formation of the given ions;
We us the exchange of valency approach to solve this problem. The valency will form the combining power of the ions for the combination.
Y³⁺ OH⁻
Combining power 3 1
Exchange of valency 1 3
Now the compound is Y(OH)₃
Which metal pan should the chef choose because it undergoes the largest temperature change for a given input of energy?
The chef should choose the copper pan.
The chef should choose the iron pan.
The chef should choose the aluminum pan.
The chef can choose any of the three pans, because all three pans will undergo the same amount of temperature change.
Answers
Answer:
If the chef is in a hurry we would assume he would want the pan to heat up so copper
Explanation:
Answer:
A. The chef should choose the copper pan.
Explanation:
Copper conducts heat well because its atoms contain only one free valence electrons in the outer shell. Elements with a low number of valence electrons transfer heat the best, and copper has only one. Valence electrons move about freely.

Both the stomach and the small intestine are involved in the digestion of food.
The churning of food by stomach muscles and peptidase enzymes in the small
intestine both break food molecules into smaller molecules.
Which statement best describes changes to food during digestion?
Answers
Answer: I think the answer is The muscle contractions result in physical changes, while the action of the peptidase results in chemical changes.
Explanation: Because the muscles would make the food smaller and the enzymes have a chemical change to it because it changes the molecules in the food.
The chemical processes in food digestion results in the formation of new
substances.
The statement that best describes the changes in food during digestion is;
The churning of the food is a physical process, which results in physical changes while the peptidase results in chemical changes of the food.
Reasons:
The given processes in the digestion of food are;
Stomach: Food churning is the process by which the small intestine vigorously turns ingested food.
Small intestine: The action of the peptidase enzyme is to increase the rate of the digestion of food.
Therefore;
The churning of the food is a physical process, which results in physical changes while the peptidase results in chemical changes of the food.

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 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.
Answers
Answer:
Explanation:
Earth's water is always in movement, and the natural water cycle, also known as the hydrologic cycle, describes the continuous movement of water on, above, and below the surface of the Earth. Water is always changing states between liquid, vapor, and ice, with these processes happening in the blink of an eye and over millions of years.

Maria walked on a beach made mostly of sand. She walked barefoot
on the beach early in the morning, and the sand was cool. When she
walked in the same area in the afternoon, the sand was hot.
Which statement best describes why the temperature of the sand
increased?
Answers
The statement that the atoms in the sand were moving more quickly best describes why the temperature of the sand is increased. The relationship between kinetic energy and temperature is explained here.
What is the relationship between kinetic energy and temperature?The temperature of a body is directly proportional to the kinetic energy. The energy acquired by those molecules which are in motion is called the kinetic energy.
The radiation of the sun falls on a number of objects on our surroundings. The objects absorb this energy till afternoon due to which they become hot.
When Maria walked in afternoon, the sand was hot as its particles have gained the kinetic energy due to which they move rapidly from one place to another. So that the sand feels more hot in the afternoon.
Thus the atoms in the sand were moving more quickly best describes the increase in temperature of the sand.

A. Many light waves traveling away from a source
O B. Two light waves traveling perpendicularly to a source
C. Several light waves circling a source
D. A single light wave traveling away from a source.
Answers
The model represents where electromagnetic radiation transmits energy should be option d. A single light wave traveling away from a source.
What is electromagnetic radiation?It is the energy that should be transmitted at the fixed velocity via the sinusoidally that varied from the electric and magnetic fields.
Here the frequency of variation of the energy should be presented by the Greek letter ν.

The model depicts the transmission of energy by electromagnetic radiation. The model depicts a single light wave departing from a source.
What describes the light as electromagnetic waves?Light as a wave: Light is a type of electromagnetic wave that can be represented mathematically (described). A shifting magnetic field is produced by a shifting electric field, according to this paradigm. Light is produced when the electric field changes as a result of the changing magnetic field.Light can be thought of as a wave. Light is a type of electromagnetic wave. A fluctuating electric field, according to this hypothesis, generates a fluctuating magnetic field. The interaction of a changing magnetic field with a changing electric field produces light. When charged particles, such as electrons and protons, move, they generate electromagnetic fields, which transport the type of energy known as electromagnetic radiation, or light.To Learn more About electromagnetic radiation, Refer:

Which of these locations is most likely to experience the least amount of snow?
Location D
Location C
Location A
Location B
Answers
According to the diagram shown, location A will receive least amount of snow in the form of precipitation.
What is precipitation?
Precipitation is defined as any liquid or frozen water which forms in the atmosphere and then gets received on Earth.It is one of the most important steps of the water cycle.
Precipitation takes place in form of clouds when water vapor gets accumulated in clouds and they get bigger and heavy, when the clouds become heavy enough they fall to the land in the form of rain.If a cloud is present at higher altitudes , the water present in the clouds freezes and fall to the ground in form of snow,hail.
Precipitation occurs always in case of fresh water because the sea salt does not evaporate with the water.The different types of precipitation are rain, drizzle,snow,snow hail,etc.
