the answer is ionic bonds
1) CCl4
2)SiO2
3)C6H12O6
4) H2SO4
The substance that has been acting as an electrolyte from the given molecules is sulfuric acid. Thus, option 4 is correct.
Electrolytes have been defined as the chemical substances that has been dissociated into constituent ions when dissolved in the aqueous solution.
The ionic compounds are bounded by weak intermolecular forces and are dissociated into ions in the solution. Thus, the compounds are given as electrolytes.
The covalent bonded molecular atoms are not dissociated into ions and are not considered as electrolytes.
The substance that has been acting as an electrolyte from the given molecules is sulfuric acid. Thus, option 4 is correct.

Positive two
Negative one
Negative two
Answer:
The correct answer is the c = negative one
Explanation:
Hello! Let's solve this!
The electron is a particle that is part of the atom. The atom is also made up of neutrons and protons. Protons have a positive charge and are located in the nucleus. Neutrons have a neutral charge and are also located in the nucleus.
The electron has a negative charge and travels its orbitals around the nucleus.
The correct answer is the c = negative one

Lab Objectives
In this lab you will:
• help the aliens, called Tinyians, build the best house on their planet called Tiny World.
• experiment with different building materials to collect data to see which ones best meet the criteria for building a home on Tiny World.
• test each building material for density, thermal and electrical conductivity, flexibility, and magnetism.
Background Research:
You will need to gather background research from the virtual lab to form a good hypothesis. Read the Welcome to Tiny World part of the lab. Use the background information you learn to answer the questions below.
Describe the gravity of Tiny World.
Part 1:
Describe the reason your house will need magnets.
Describe the climate of Tiny World.
Hypothesis:
In this section, include the IF/THEN statements you developed during your lab activity. These statements reflect your predicted outcomes for the experiment.
A If we use _______ to build the roof of the house, then the temperature inside the house will remain cooler.
B If we use_______ to build the walls and floors of the house, then the temperature inside the house will remain cooler.
C If we use ______ to bring electricity into the home, then it will allow electricity to flow into the home at a faster rate.
D If we use_______ to construct the latches on the windows and doors, then the magnetism will keep the latches secure.
Part 2
Procedure:
1. You will test each building material for density, thermal and electrical conductivity, flexibility, and magnetism.
2. Record your observations in the data table provided below.
3. Repeat steps with all test materials.

part 3
Conclusion
Your conclusion will include a summary of the lab results and an interpretation of the results. Please answer all questions in complete sentences using your own words.
1 Using two to three sentences, summarize what you investigated and observed in this lab.
2 What was the independent variable in the lab?
3 What was the dependent variable in the lab?
4 Did each of your experiment results support, or fail to support your four hypotheses? A.
B
C.
D.
5 Why do you think a building material's density is important when building homes or architectural structures?
6 Why wouldn’t you choose wood or aluminum for the latches on your house?
7 Which material has the highest thermal conductivity?
8 Which material has the highest electrical conductivity
9 Based on your data, explain why these materials have the highest thermal and electrical conductivity?
10 Think about where you live now or where you have lived in the past; use complete sentences to describe this environment and the weather.
Answer:
The purpose of the "Measuring Physical Properties Lab Report" is to test the physical properties of different building materials in order to choose the most suitable materials for a new home in Tiny World. The lab objectives include helping the Tinyians build their best house, experimenting with different materials to collect data, and testing each material for density, thermal and electrical conductivity, flexibility, and magnetism.
The background research will provide information about Tiny World, including its gravity, climate, and other relevant details. The hypothesis section requires you to make IF/THEN statements based on the lab activity. For example, IF we use a certain material for the roof, THEN the temperature inside the house will remain cooler.
In part 2, the procedure involves testing each building material for density, thermal and electrical conductivity, flexibility, and magnetism. You need to record your observations in the data table provided.
In part 3, the conclusion should summarize the lab results and provide an interpretation of the results. It also includes answering questions about the independent and dependent variables in the lab, whether the experiment results support or fail to support the hypotheses, and explanations about the importance of density in building materials, why wood or aluminum wouldn't be suitable for latches, and which materials have the highest thermal and electrical conductivity.
Finally, you are asked to describe the environment and weather of a place you have lived in the past or currently live in, using complete sentences.
Hope this helps :)
