The gross colors can be imparted to the flame by the metal ion solutions .
1.To serve as an excitation source, turn on a Bunsen burner.
2. Perform flame tests on the chloride solutions of Li+, Na+, K+, Ca2+, Sr2+, and Ba2+ as instructed by your lab instructor. Wearing the unique glass blower glasses, take note of the obscene hue that each ion contributes to the flame. With one exception: in order to view the sodium flame, you must remove the special glasses that suppress sodium emissions.
3. Obtain two unidentified answers and note their numerical values. Using the ugly hue the solution gives the flame as a guide, identify the metal ions that are present.
One of the six ions you tested will make up the particle.

Answer: 1.788 volts.
Explanation:
To solve this problem we can combine battery cells to create higher voltages. Building more lemon batteries and connecting them with a metal wire from "+" to "-" adds the voltage from each cell. The two lemon batteries above, combine to produce a voltage of 1.788 volts.
Answer:
Add more substrate.
Explanation:
First let's explain why all the other options are wrong:
- The problem states that we <u>have optimum pH and optimum temperature</u>, this means that any change to those factors (increasing or decreasing) would slow down the reaction.
- <u>An inhibitor is called that way because its presence slows downs the reaction</u>, so more inhibitor would not speed up the reaction.
A <em>competitive inhibitor</em> is a substance that resembles the substrate that normally reacts with the enzime, so it binds to the enzime's active sites and prevents the substrate from doing so. Adding more substrate makes it more likely than a substrate molecule binds to an enzime's active site instead of the inhibitor ("it will outcompete the inhibitor and increase the reaction rate").
Answer:
A
Explanation:
organs are made of tissue so it can't be D.
plant are made up of organs like roots, leaves, etc. so it can't be C.
skin (is an organ) is made up to 7 layers of ectodermal tissue so isn't B.
