How could a chemist find out how much mass is given off as gas during a chemical change?
How could a chemist find out how much mass is given off as gas during a chemical reaction
Did the chemist use adequate experimental controls?
Yes, the chemist utilized appropriate experimental controls to ensure the reliability and validity of the results. Controls are essential in experiments to account for any variables that could influence the outcome and help establish a baseline for comparison.
When chemist watches the temperature of a vat of liquids and notices that it decreases over time.What can the chemist conclude from this observation?
The chemist can conclude that there is an ongoing process in the vat that is absorbing heat from the liquid, causing the temperature to decrease. This could indicate a chemical reaction taking place or heat loss to the surroundings. Further investigation is needed to determine the exact cause of the temperature decrease.
What is the common chemical in a chemical reaction?
Oxygen as most reactions have it although it could also be hydrogen
What type of chemical reaction could take place between these reactants Fe (s) and CuSO4 (aq)?
The chemical reaction is:Fe + CuSO4 = FeSO4 + CuIt is a single displacement reaction.

A chemist interested in the efficiency of a chemical reaction would calculate the?
The chemist would calculate the reaction yield, which is the amount of product formed compared to the theoretical maximum amount that could be obtained. This provides a measure of how efficient the reaction is at converting reactants into products. Additionally, the chemist may also calculate reaction rate to determine how quickly the reaction proceeds.
What change could happen during a chemical reaction?
the chemical shall be changed
What subsequent experiment might the chemist want to conduct to build on her experiment?
The chemist could investigate the effect of different solvents on the rate of reaction to determine if solvent polarity plays a role. She could also vary the concentration of the reactants to explore how it influences the rate of reaction. Additionally, she could study the effect of temperature on the reaction rate to understand how kinetic energy affects the rate of the reaction.

What are some problems that chemist must consider when developing new technologies?
To be sure that there's no chemical interactions that could cause them harm and to make sure that the chemist doesn't injure them self.
What is it called when one or more substances change into one or more new substances?
This could refer to a chemical transformation (chemical change), a chemical reaction, or spontaneous change. Some changes require another substance or substances to be mixed together. Some reactions will occur by themselves without any outside manipulation or stimulation.

What is changed in the original substance during a chemical reaction?
It all depends on what chemicals you are using. For example, if you were using sulfur & carbon, either one could be changed.
The energy released when a chemical compound reacts to produce new compounds?
This is known as the heat of reaction, which represents the energy change that occurs during a chemical reaction. It can be exothermic (energy is released) or endothermic (energy is absorbed). Heat of reaction is typically measured in kilojoules per mole of the reactants.
