Yes, turning litmus paper red from blue is a chemical change because the color change results from a chemical reaction between the litmus paper and the substance it comes into contact with, indicating a change in the chemical composition of the paper.
Non abrasive refers to a product or substance that is not harsh or rough enough to cause damage when it comes in contact with a surface. It is gentle and safe for use on delicate materials or surfaces.
Magic marbles are designed to absorb water due to the material they are made of, such as a superabsorbent polymer. When water comes into contact with the marbles, the polymer chains in the material expand and create a gel-like substance that traps and holds the water within the marble. This results in the magic marbles swelling in size as they absorb more water.
An iodine solution turns a purplish-black if it comes into contact with the presence of a starch molecule. This reaction can take place at very minute concentrations of starch.

When iodine comes into contact with starch, a chemical reaction occurs that results in the formation of a dark blue or black color. This reaction is used as a test to detect the presence of starch in a substance.
Contact with a hazardous substance refers to any situation where a person or environment comes into direct interaction with a material that poses health or safety risks. This can occur through inhalation, skin absorption, ingestion, or environmental exposure. Such substances may include chemicals, biological agents, or radioactive materials that can cause harm to human health or the environment. Proper safety measures and protocols are essential to minimize the risks associated with such contact.
The condition that typically comes before addiction is substance abuse, where a person engages in harmful or hazardous use of a substance. This can lead to increased tolerance, dependence, and ultimately addiction.
Yes, dioctyl phthalate is classified as a hazardous substance. It is considered harmful if ingested, inhaled, or if it comes into contact with the skin and eyes. It is important to handle and store it properly to prevent any health risks.
Cytokinesis is halted. Removal of said substance allows Cytokinesis to resume.
Yes, potassium metal is hazardous due to its reactivity with water and air. It can ignite spontaneously in contact with moisture, and can cause burns if it comes into contact with skin. Special precautions are needed when handling potassium metal to prevent accidents.
Yes, isopropyl alcohol can burn when it comes into contact with skin because it is a flammable substance that can cause irritation or a burning sensation on the skin.
When bleach comes into contact with skin, it can feel slimy because it reacts with the natural oils on the skin to form a slippery soap-like substance.
Iron oxide is considered a non-hazardous material with low toxicity. However, it can cause irritation or harm if inhaled in large quantities or if it comes in contact with skin or eyes. It is important to take appropriate safety precautions when handling iron oxide.
Heat is a measure of the molecular and atomic excitation of the substance, i.e. the degree of vibration that it has available to impart to other substances that it comes into contact with.
