Google says it is 9.01218, idk if that helps
Answer:
b
c
250 mL
Explanation:
The second equation is: Molarity 1 x Volume 1 = Molarity 2 x Volume 2
Plug in, solving for Volume 2
Solve
Answer:
Mean rate of reaction produced = 0.533 g/sec (approx.)
Explanation:
Given:
Reaction produced = 1.6 gram
Time taken = 30 sec
Find:
Mean rate of reaction produced
Computation:
Mean rate of reaction produced = Reaction produced / Time taken
Mean rate of reaction produced = 1.6 / 30
Mean rate of reaction produced = 0.533 g/sec (approx.)
Answer:
05.01 Electromagnetic Spectrum

Electromagnetic Energy Example One
Activity: Microwave
Type of electromagnetic energy: Microwaves are a form of "electromagnetic" radiation
Picture:
Description of use: They are waves of electrical and magnetic energy moving together through space. Electromagnetic radiation spans a broad spectrum from very long radio waves to very short gamma rays.
Electromagnetic Energy Example Two
Activity: Cellphone
Type of electromagnetic energy: Radiofrequency
Picture:
Description of use: What type of energy does a cellular phone use? Cell phones (and cell phone towers) use low-powered radiofrequency (RF) energy, a type of non-ionizing radiation. Non-ionizing radiation is not able to break the chemical bonds in your body.
Electromagnetic Energy Example Three
Activity: AM and FM radio
Type of electromagnetic energy: Electromagnetic radiation
Picture:
Description of use: Radio waves are a type of electromagnetic radiation best-known for their use in communication technologies, such as television, mobile phones and radios.
The three things are increasing temperature, grinding calcite, and using catalyst are applied to make the reaction occur quickly.
Explanation:
To make the reaction occur more quickly the following three things are done.
Increasing temperature:
Increase in temperature increases the kinetic energy of molecules. This results in increase in the velocity and rate of collisions between reactants. Hence, greater the number of collisions between reactants per time greater will be the probability of formation of product per unit time.
Grinding Calcite:
Grinding of calcium carbonate results in the increase of surface area of calcite. So greater the surface area greater is the exposure of calcium carbonate to HCl molecules, thus the rate of formation of product increases.
Using Catalyst:
By using the catalyst it decreases the activation energy and increases the rate of reaction by following methods they are providing new pathway, weakening the bonds, providing surface area and holding up the reactant close to each other.
