The group of students is incorrect. Boiling water is NOT a chemical change. The group incorrectly identified it as a chemical change because the water changed to steam and bubbles.
Boiling water is a physical change to steam and bubbles but it is still water. The steam puts itself into the air as evaporation. The opposite of evaporation is condensation, when water vapor condenses back into tiny droplets of water.
A chemical change is when something changes and becomes a new substance or property, like burning wood.
A physical change is when the appearance or form of the substance changes but the kind of substance doesn’t, just like the boiling water.
A student uses red litmus paper to test the pH value of different solutions. Which would result in a color change of the litmus paper?
soap
vinegar
lemon juice
antifreeze
Answers
The litmus paper shows red colour for acidic substances and blue colour for basic substances. Thus a red litmus paper will turn blue if it is dipped in an alkaline solution. Soap is alkaline and given blue color to litmus.
What is pH?pH of a substance is its measure of concentration of H+ ions in it. It is mathematically negative logarithm of H+ ion concentration. Thus, pH measures how much acidic or basic the solution is.
A pH of of 7 is neutral having no acidity or basicity. A pH less than 7 is acidic and pH greater than 7 is basic in nature. Vinegar is acetic acid and it shows less pH . Lemon juice also acidic since it contain citric acid whereas, soap is basic.
A litmus paper is used to identify whether a substance is acidic or basic. It shows red color for acidic solutions and blue for basic solutions. If the red litmus paper is dipped in acidic one, it shows no colour change if it is dipped in basic solution then it turns to blue.
Soap is highly alkaline and it changes red litmus paper to blue.

How did magnets move objects during the hands-on activity and in the Sim? Explain your reasoning.
Answers
Answer:he force with which a magnet pulls or pushes on something attracted to it or repelled by it is dependent on the distance between the magnet
Explanation:
Magnets move objects due to magnetic force. This force is created by the magnetic field generated by the magnet which attracts or repels other magnetic materials, causing them to move. In the hands-on activity, this can be observed by placing a magnetic object near the magnet and observing its movement towards or away from the magnet. In the Sim, the movement is simulated through the use of computer algorithms and programming, showing the magnetic forces and movements in a virtual environment.

a major use of magnesium oxide is as a refractory material.
explain in terms of structure and bonding, why magnesium oxide has a very high melting point.
[ this is 4 marks, please provide a good answer ]
[ giving brainliest + thanks on profile ]
Answers
Sodium oxide has a high melting point because of the strength ofits bonds. Due to having strong bonds, they cannot be broken veryeasily. Magnesium chloride is ionic compound. There is a strong electrostatic force of attraction between 2 chloride atoms and 1 magnesium atom.
Because it retains its strength at very high temperatures. It is considered a refractory material with a melting point of 6500 degrees F. It is also very non-reactive with other materials that might be put into the furnace and is even used to make crucibles - containers used to melt other substances.
The strength of ionic bonds usually depends on two factors - ionic radius and charge. Mg+2
and O−2 have charges of +2 and -2 respectively. This is larger than the charges of other ions like Na+ or NO-3. Magnesium ions and oxygen ions also have small ionic radius. Magnesium is in period 3 so its ion is smaller than that of calcium or barium. Oxygen ion is smaller than sulfide and fluoride. The smaller the ionic radii, the smaller the bond length and the stronger the bond. Therefore the ionic bond between magnesium and oxygen is very strong.

In this experiment, you will use a natural indicator to indirectly determine the H+ concentration of some common household solutions to determine a physical characteristic of the solution. In the space below, write a scientific question that you will answer by doing this experiment.
Answers
Some of the scientific questions that may be answered through the experiment are:
(1) What are the physical changes that may occur in the solution or the indicator when added with acidic/basic solution?
(2) How much of the indicator is needed in order to bring about a significant physical change in the solution to identify its H+ concentration?
if wrong i sry :(
By determining the H+ ion concentration of a solution, we can measure the pH of the solution and thereby to check its acidity. Thus, by doing this experiment, we are answering the question that the what is the pH of the household solutions, and they are acidic or basic?
What is pH?pH of a solution is the measure of its H+ ion concentration. Mathematically it is the negative logarithm of the H+ ion concentration. The pH of a solution tells it is acidic or basic.
pH of 7 is neutral solution and a pH below 7 is acidic whereas a pH above 7 is basic solution. We can use natural indicators such as cabbage juice to determine the pH of house hold solutions such as lemon juice, milk, soap solution etc.
A color change of red is given by acidic solutions ad that of blue indicating the basicity. Hence, the scientific question will be to determine pH range of the solutions.

In an electrical wire, if instead of copper, plastic wire is used. Would it conduct electricity?Justify your answer.
Answers
Answer:
No, a plastic wire would not conduct electricity. This is because plastic is an insulator that does not allow electric current to flow through it. In a wire, electrical conductivity is provided by the movement of charged particles - typically, electrons. Copper is an excellent conductor of electricity because it has a high number of free electrons that are not bound to atoms and can move through the wire very easily. However, in a plastic wire, the tightly bound electrons of its atoms do not allow for the free flow of charges, thus preventing the passage of electric current.
