Answer:

The correct answer is "Oxygen is released into the atmosphere through stomata."

Explanation:

A plant needs water, (H₂O) carbon dioxide, (CO₂) and light energy to produce food that is oxygen (O₂) and glucose through a process known as "photosynthesis".

Water + Carbon dioxide + Light energy = Oxygen + Glucose

In the attached diagram, it is shown that plant releases oxygen into the atmosphere through the leaves (stomata).

The stomata controls the flow of oxygen and carbon dioxide into and out of the plant whereas xylem is used for the transportation of water from the roots to the leaves in the plant.

The process of photosynthesis only happens when the light is present, plants have a pigment named "chlorophyll" which absorbs the light energy.

Calculate the percent errorin a length measurementof 4.45cm if the correct value is 4.06
FinnZ [79.3K]

Answer:

9.6 %

Explanation:

<u>Step 1: How to define  percent error ? </u>

⇒ % error is the difference between a measured value and the known or accepted value

⇒Percent error is calculated using the following formula:

⇒%error  =  | Experimental value-theoretical value/theoretical value |  x100%

⇔ this can be written as well as : error = (| Experimental value/ theoretical value | - | Theoretical value / Theoretical value | ) x100%

<u>Step 2: Calculate % error</u>

In this case, this means :

%error = ( |(4.45 cm - 4.06cm ) / 4.06cm | ) x100%

%error = 0.096 x100%

%error =9.6 %

When electrons are filling energy levels, the lowest energy sublevels are occupied first. This is ____________.
Nimfa-mama [501]

When electrons are filling energy levels, the lowest energy sublevels are occupied first. This is Hund's rule.

Hund's rules state that:

Every orbital in a sublevel has to be singularly occupied before any other orbital is able to be doubly occupied.

All of the electrons in single occupied orbitals have to have the same spin to maximize the total spin.

Anyone think they can help me with this one?
BARSIC [14]
To name this Alkyne, simply count from the direction that will give the lowest starting number to appear at the beginning of the carbon triple bond.

If you were to count from the top of the chain, the position of the carbon next to the triple bond would be 4. Yet if you count from the bottom chain going left to right and above the chain, the position of the carbon next to the triple bond would be 3.

Then identify the groups that are connected off the parent chain, here we have a methyl group on carbon 2.

Thus the name would be 2 - methyl - 3 - heptyne. I believe.
