How do reactants and products compare in a chemical reaction?

Reactants are the starting materials that undergo chemical changes to form products in a reaction. Reactants are consumed during the reaction, while products are the new substances formed. The number of reactant molecules generally equals the number of product molecules in a balanced chemical equation.


When analyzing the possible reaction between ZnCl2and Br2 you must first compare the activities of which two elements?

When analyzing the possible reaction between ZnCl2 and Br2, you must first compare the activities of zinc (Zn) and bromine (Br) as they are the reactive elements in this case. By comparing their activities, you can determine if a displacement reaction will occur, where the more reactive element will displace the less reactive one from its compound.


What is molality of a solution?

Molality is a measure of solute concentration in a solution expressed as the number of moles of solute per kilogram of solvent. It is often used in place of molarity for concentrated solutions or when temperature changes significantly. Molality accounts for changes in volume due to temperature, making it a more reliable measure of concentration in some cases.


What simple experiment might you perform to test the hypothesis that an enzyme combines with its substrate when it acts?

You could perform a simple enzyme activity assay. Mix the enzyme with its substrate and monitor the reaction rate over time using a spectrophotometer to measure any changes in absorbance or using a colorimetric assay to detect product formation. Compare the reaction kinetics with a control group lacking either the enzyme or the substrate to determine if the enzyme-substrate combination is necessary for the reaction to occur.


Compare the total amount of energy before and after physical and chemical changes?

In physical changes, the total amount of energy before and after remains the same as no new substances are formed. In chemical changes, there may be a difference in the total amount of energy before and after the reaction due to the formation of new substances and the breaking or forming of chemical bonds.

How do changed in temperature and activation energy compare in how they affect reaction rate?

Changes in temperature and activation energy have opposite effects on reaction rate.


Which has the largest rate constant?

To determine which reaction has the largest rate constant, you would need to compare specific reactions under similar conditions (temperature, concentration, etc.). Generally, reactions that are elementary and have fewer reactants tend to have larger rate constants. Additionally, factors such as activation energy and temperature play a crucial role; reactions with lower activation energies at higher temperatures typically exhibit larger rate constants. If you provide specific reactions or conditions, I can give a more tailored answer.


What are two things you can list and compare to help you predict results of solutions?

The concentration of reactants: Higher concentrations usually lead to faster reaction rates and higher yields. The temperature: Increasing temperature typically increases reaction rates by providing more energy for molecules to react.

In a hydrogen peroxide and yeast experiment what is the purpose of the cups with yeast and nothing?

The cups with yeast and nothing serve as a control in the experiment to compare the rate of reaction when hydrogen peroxide is added. By observing how the control cup behaves without the hydrogen peroxide, we can compare any changes in the cups with yeast and hydrogen peroxide to see the effect of the reaction.
