Are there limits to what questions science can answer?
it depends on the question because some questions are unknown or don't have any scientific proof to answer your question
What measurements must be unknown in order to find density of a substance?
There are multiple definitions for density depending on the precise science or engineering application. However, density typical is the ratio of mass to volume. Therefore, you must know both mass and volume to calculate density.Density = mass/volumefor exampleD=M/VD= 120g/40mLD= 3 g/mL
What is the science safety symbol for never taste or smell an unknown substance?
The science safety symbol for never tasting or smelling an unknown substance is a image of a nose and a mouth crossed out with a red line, often accompanied by the text "Do Not Taste or Smell." This symbol is used to warn individuals against using their senses to identify a substance, highlighting the importance of proper labeling and handling procedures in the laboratory.
Why would we need to know the conductivity of a unknown substance?
Knowing the conductivity of an unknown substance helps identify its ionic or molecular nature, which is crucial in various fields such as chemistry, materials science, and environmental monitoring. Conductivity can indicate the presence of dissolved ions, revealing information about the substance's purity and potential applications. Additionally, it can aid in assessing the substance's behavior in different environments, such as its suitability for electrical applications or its impact on biological systems. Understanding conductivity is essential for quality control and ensuring safety in industrial and laboratory settings.
If you found an unknown substance in your home how could you find out what it was?
Take it to a testing laboratory or the police. They can figure out what most things are, and tell you if you need to clean it up, report it all or get the heck out of that house.
Why is it not advisable to smell unknown gas in a laboratory?
because can be dangerous
A scientist has analyzed the chemicals that make of a sample of an unknown substance. Which chemicals would be the best indicator that the unknown substance is a plant?
cellulose and starch
How can a titration help you to determine the concentration of an unknown substance?
In a titration, a known concentration of a substance (titrant) is added to the unknown substance until a chemical reaction reaches completion. By measuring the volume of titrant required to reach a specific endpoint, the concentration of the unknown substance can be calculated using the stoichiometry of the reaction.
What kind of substance is iron sulphide?
unknown
What is unknown substances?
Unknown substances are materials whose composition or properties are not readily identifiable or known. These substances may require analysis or testing to determine their characteristics, which can help determine their potential uses or hazards. It is important to handle unknown substances with caution until their nature is determined.
When a unknown substance cannot be broken down into a simplier substance it is?
You think probable to an atom.

What is the purpose of chemical laboratory test?
Chemical laboratory tests are used to analyze the composition and properties of substances. They are essential for identifying unknown substances, monitoring chemical reactions, assessing purity levels, and ensuring safety and quality in various industries such as pharmaceuticals, food, and environmental science.
Knowing the solubility of an unknown substance in water can help to identify what it is.?
Knowing the solubility of an unknown substance in water can help you calculate its molarity. It is however important to get its weight first.
