Hypothesis: Which materials do you think will meet the special needs of Parvus' house? Use the drop-down selections to create your hypotheses. Be sure to record your hypotheses on your lab report. If we use Select to build the roof of the house, then the temperature inside the house will remain cooler. If we use Select to build the walls and floors of the house, then the temperature inside the house will remain cooler. If we use Select to bring electricity into the home, then it will allow electricity to flow into the home at a faster rate. If we use Select to construct the latches on the windows and doors, then the magnetism will keep the latches secure.
Answer:
This question is incomplete as it lacks the options for each hypothetical statement. The options for each hypothesis are:
wood, clay brick, iron, aluminum, copper, or nickel
The answers to each hypothesis are:
1. Wood
2. Clay brick
3. Copper
4. Iron
Explanation:
Firstly, a hypothesis is a testable explanation given to explain an observed problem or to answer a question. In this case, "which materials will meet the special needs of Parvus' house?" is the question.
The question requires one to complete the given hypotheses using the options given.
- If we use WOOD to build the roof of the house, then the temperature inside the house will remain cooler. The best answer is "wood" because wood conducts/absorbs heat the least among the materials that can be used for roofing, hence, it will make the inside of the house cooler.
- If we use CLAY BRICK to build the walls and floors of the house, then the temperature inside the house will remain cooler. Clay brick is the best material for building walls and floors of a house among the option. Also, it conducts heat fairly making the interior of the house cool.
- If we use COPPER to bring electricity into the home, then it will allow electricity to flow into the home at a faster rate. Copper, among all other metal, is the best conductor of electricity due to its properties including low resistivity. Hence, using copper will make electricity to flow into the home at a faster rate.
- If we use IRON to construct the latches on the windows and doors, then the magnetism will keep the latches secure. Iron is the metal with the best magnetic property. Therefore, using it to construct the latches on the windows and doors will guarantee magnetic security.

At present, fusion reactions... Group of answer choices produce the energy in some nuclear power plants. cannot be used to produce energy in reactors. produce the energy in all recent nuclear power plants. produce the energy in most nuclear power plants.
Answer:
cannot be used to produce energy in reactors.
Explanation:
Currently, there is no reactor that can allow the use of nuclear fusion, although nuclear plants use nuclear fission reactors.
Nuclear fusion happens when thousands of atoms collide with each other when they are in the midst of extreme conditions of literature and pressure. This collision causes the atoms to fuse, creating another element. The process releases amounts of light and heat, promoting a high release of energy. This whole process occurs without the release of CO2 into the atmosphere, without the release of toxic waste and without the risk of explosions, which makes nuclear plants have a strong interest in building a reactor to use this type of energy. For this reason, scientists from different countries have collaborated with each other on a project called Iter, which seeks to build a reactor and achieve the first reaction in 2025.

Ionic or covalent
C Cl
Formula ____________ Ionic or covalent
Mg Cl
Formula _____________
C Cl is a covalently bonded compound with the formula CCl₄. MgCl is an ionic compound with the formula MgCl₂.
What is meant by chemical bonding?The formation of a chemical bond between two or more atoms, ions or molecules to form a chemical compound is known as chemical bonding. The chemical bonding makes sure the atoms are together in the resulting compound.
Chemical bonding is made possible by an attractive force resulting from the overall loss of energy in the resultant molecule compared to its constituents.
Chemical compounds depend on chemical bonding for their stability. There are various kinds of chemical bonds formed. Covalent bonds and ionic bonds are 2 of the most commonly known chemical bonds.
Covalent bonds are formed by the sharing of electrons and an ionic bond is formed by the electrostatic force of attraction between the atoms.
Therefore, in the given examples, C Cl is a covalently bonded compound with the formula CCl₄. MgCl is an ionic compound with the formula MgCl₂.

Plz, Help :/ you can choose any question you want or all of it if you pleased.
Answer:
29. Proteins support the body's structural framework, chemical reactions, and contractions (muscle movement).
30. Proteins have a primary structure (polypeptide chain of amino acids), secondary structure (made up of alpha helices and beta pleat sheets), tertiary structure (superimposed on secondary structure), and quaternary structure (2 or more polypeptide chains with its own tertiary structure).
31. Protein molecules can denature if conditions aren't right, such as the wrong temperature or pH level. When denatured, proteins typically lose their shape and their function for a short time because their active sites become deactivated (though if conditions are too extreme, they can permanently lose their function). This happens to globular proteins because they are not nearly as stable as fibrous proteins due to their functional 3D shape.
I just did the first 3 since I could easily access the proteins section in my textbook at the moment. :)

Element Y has two naturally occurring isotopes. The most dominant isotope has a mass of 114.3789 amu and a percent abundance of 64.23%. What is
the mass of the second isoptope if the average atomic mass is 128.4359 amu? Remember that the two percentages will have to sum to 100%.
Answer to the correct number of sigtigs including units in your answer.
(to receive full credit, work must be submitted for this question)
Answer:
153.6771 amu
Explanation:
From the question given above, the following data were:
Isotope A:
Mass of A = 114.3789 amu
Abundance (A%) = 64.23%
Isotope B:
Mass of B =.?
Abundance (B%) = 100 – A%
Abundance (B%) = 100 – 64.23
Abundance (B%) = 35.77%
average atomic mass of Element Y = 128.4359 amu
The mass of the 2nd isotope (i.e isotope B) can be obtained as follow:
Average atomic mass = [(Mass of A × A%)/100] + [(Mass of B × B%)/100]
128.4359 = [(114.3789 × 64.23)/100] + [(Mass of B × 35.77) /100]
128.4359 = 73.4656 + (Mass of B × 0.3577)
Collect like terms
128.4359 – 73.4656 = Mass of B × 0.3577
54.9703 = Mass of B × 0.3577
Divide both side by 0.3577
Mass of B = 54.9703 / 0.3577
Mass of B = 153.6771 amu
Therefore, the mass of the 2nd isotope is 153.6771 amu

Draw the electric field lines between a proton and an electron. According to Coulomb's law, how would the electrical force between these particles change if the product of their electrical charge increased?
Explanation:
An electron has a negative charge and a proton is a positively charged particle. Electric field lines are used to express the direction of the electric field. For a positive charge, it is outwards while for a negative charge it is inwards. The attached figure shows the electric field lines between a proton and an electron. The field lines emerge from proton and terminate at electron.
The electrical force between charges is given by :
[tex]F=k\dfrac{q_1q_2}{r^2}[/tex]
r is the distance between charges
The force is directly proportional to the product of charges. It means that if the product of electrical charge increased, it means that the electrical force will increase proportionally.
