What else can I help you with?
How does temperature affect the rate dissolving?
Generally, increasing the temperature of a solution increases the rate of dissolving. This is because higher temperatures increase the kinetic energy of the solvent molecules, allowing them to break apart the solute particles more effectively. However, this relationship may vary depending on the specific solute and solvent involved.
What risks are involved by doing the floating egg in salt water experiment?
There are no serious/significant risks involved in the experiment.
What chemicals are involved in coagulation?
Platelet
What is true of chemicals?
Chemicals are substances composed of atoms or molecules that have distinct properties and structures. They can be found in various forms, including solids, liquids, and gases, and are involved in numerous chemical reactions that transform them into different substances. Chemicals play a critical role in everyday life, from the food we eat to the products we use, and they can be both beneficial and harmful depending on their nature and concentration. Understanding chemicals is essential for fields such as chemistry, biology, environmental science, and medicine.
What part of a leaf contains chemicals needed for photosynthesis?
The chloroplasts, specifically found within the cells of the mesophyll tissue, contain the chemicals needed for photosynthesis to occur in a leaf. These chemicals include chlorophyll, which is responsible for capturing light energy, and other molecules essential for the series of reactions involved in photosynthesis.
Why should you wash your hand after a science experiment?
This actually depends upon the particular kind of experiment you were doing, but many science experiments involve chemicals that you would not want to get into your food by accident. If it was a biological experiment, there could be dangerous germs involved.
What is the taste of the rosidue?
The taste of the residue (not rosidue) will vary greatly depending on what chemicals are involved in the experiment. For example, salt residue will taste like salt.
How does temperature affect the rate dissolving?
Generally, increasing the temperature of a solution increases the rate of dissolving. This is because higher temperatures increase the kinetic energy of the solvent molecules, allowing them to break apart the solute particles more effectively. However, this relationship may vary depending on the specific solute and solvent involved.
What risks are involved by doing the floating egg in salt water experiment?
There are no serious/significant risks involved in the experiment.
What is a statement that describes what you think will happen in an experiment?
I predict that as the temperature increases, the rate of reaction will also increase due to the higher kinetic energy of the molecules involved.
A thing that represents something involved in an experiment?
A variable represents things that are involved in an experiment. The control is the variable that doesn't change regardless of the experiment.
What chemicals are involved in coagulation?
Platelet
When two chemicals react when they are mixed the chemicals are called?
The chemicals which are involved in a reaction are called Reagents or Reactants
Explain why dissolving is a physical change?
All physical changes are reversible because the molecules do not undergo change in any chemical reaction even in in the change in the state of matter. NaCl is a salt compound and each molecules gets easily dissolved in water and the salt recovered by evaporation of water.
When does a mixture become a solution?
I think that this is involved with somehow particles dissolving and creating solutions
Which molecules are involved in photosynthesis and respiration?
In photosynthesis, molecules involved are carbon dioxide (CO2), water (H2O), and sunlight. In respiration, the molecules involved are glucose (C6H12O6) and oxygen (O2).
What chemicals are involved in motivation?
