Eat at Joe's! Did you know that this neon sign is experiencing a change of state? When a neon sign lights up, like the one you s

ee here, something is happening to the neon atoms inside the tube. How is this colorful sign related to kinetic energy and phase change? A) The electrical current in the tube generates the neon gas that glows in the dark. B) Electrical energy excites the neon atoms. They spin faster in the tube producing electromagnetic waves that we see as colors. C) Neon atoms accelerate once electrical energy is turned on to the tube. The faster the atoms move in the tube, the brighter the glow we see. D) Electrical energy accelerates the electrons in the neon gas. The gas ionizes and becomes plasma, containing both positive and negative ions.

Strigol is an important plant hormone that is released by crops such as rice and sugarcane. Unfortunately for these plants, stri
Len [333]

The hydrogen deficiency index( HDI) of strigol is = 10

<h3>How to calculate HDI:</h3>

The hydrogen deficiency index is used to measure the number of degree of unsaturation of an organic compound.

Strigol is an example of an organic compound because it contains carbons and hydrogen.

To calculate the HDI using the molecular formula given (C19H20O6) the formula for HDI is used which is:

hdi =  \frac{1}{2} (2c + 2 + n - h - x)

where C = number of carbon atoms = 19

n= number of nitrogen atoms = 0

h= number of hydrogen atoms = 20

X = number of halogen atoms = 0

Note that oxygen was not considered because it forms two bonds and has no impact.

There for HDI =

\frac{1}{2} (2 \times 19 + 2 + 0 - 20 - 0)

HDI=

\frac{1}{2} (40 - 20)

HDI =

\frac{1}{2}  \times 20

HDI = 10

Therefore, the hydrogen deficiency index of strigol is = 10

4. What is the difference between an open system and a<br> closed system?
Nimfa-mama [501]

Systems can exist in three ways as open systems, closed systems, and isolated systems. The main difference between open and closed system is that in an open system, matter can be exchanged with the surrounding whereas, in a closed system, matter cannot be exchanged with the surrounding.

btw why not just look it up on google? btw btw brainliest plz

HELP PLEASE THE OTHER 'ANSWER' ISNT EVEN AN ANSWER!
hodyreva [135]

Answer:

most likely that (2) the replicated experiment was performed incorrectly.

Why, u ask? u dare question me:

1- The initial experiment invalidness cannot be proven.

2- <em><u>t</u></em><em><u>h</u></em><em><u>e</u></em><em><u> </u></em><em><u>s</u></em><em><u>e</u></em><em><u>c</u></em><em><u>o</u></em><em><u>n</u></em><em><u>d</u></em><em><u> </u></em><em><u>a</u></em><em><u>n</u></em><em><u>s</u></em><em><u>w</u></em><em><u>e</u></em><em><u>r</u></em><em><u> </u></em><em><u>i</u></em><em><u>s</u></em><em><u> </u></em><em><u>c</u></em><em><u>o</u></em><em><u>r</u></em><em><u>r</u></em><em><u>e</u></em><em><u>c</u></em><em><u>t</u></em>

3- Different labaratories does not effect the outcome, as long as the parameter and environment of the replicated experiment is the same as when the initial experiment was conducted.

4- Already knowing the data and errors would increase the precision of the replicated experiment.

5- Change in variables should still be in the objective (or purpose) of the experiment, thus, major difference in the outcome should not happen.

happy learning!
