The light energy captured during photosynthesis is stored as
water.
sugar.
carbon dioxide.
electrons.
Answer:
Sugar
Explanation:
This is because water and carbon dioxide are required during photosynthesis. Oxygen along with glucose, that is a type of sugar is produced. The oxygen is diffused out in to the air, while the sugars are stored in the leaf thus light energy captured during photosynthesis is stored as 'sugar'

A tank for storing liquid as a base of area 1.5 meters square. What is the pressure on the base of the tank when it contains water weighting 4500n
Answer:
3000 Nm^2
Explanation:
We must remember that pressure is defined as force per unit area.
We have been given the following information in the question;
Area of the tank= 1.5 m^2
Weight of water in the tank = 4500N
And;
P = F/A
F= force
A = area
P = 4500 N/1.5m^2
P= 3000 Nm^2

Answer:
1-1) NaHCO3 + CH3COOH --> NaCH3COO + H2O + CO2
1-2) 0.5 mole of CO2
2-1) 2C4H10 + 13O2 --> 8CO2 + 10H2O
2-2) 4 mol CO2
Explanation:
Question 1
NaHCO3 + CH3COOH --> NaCH3COO + H2O + CO2
To balance the equation, count the number of atoms on both sides of the equation
(1 Na, 1+3+1H, 1+1+1C, 3+2Oxygen) --> (1 Na, 1+1+1C, 3+2H, 2+1+2Oxygen)
Combining the pluses will give you the following
(1 Na, 5H, 3C, 5Oxygen) --> (1 Na, 3C, 5H, 5Oxygen)
Both sides are the same, therefore the chemical equation is balanced (originally).
From the equation, we can see that 1 mole of NaHCO3 produces 1 mole of CO2.
So that means 0.5 mole of NaHCO3 would produce 0.5 mole of CO2.
Question 2
C4H10 + O2 --> CO2 + H2O
Again, count the number of atoms on both sides of the equation
(4C, 10H, 2O) --> (1C, 2H, 3O) This time left does not equal right side
You now need to find factors that can make both sides equal.
C4H10 + O2 --> 4CO2 + H2O Now the C is balanced, let's recount
(4C, 10H, 2Oxygen) --> (4C, 8+1Oxygen, 2H) H&O is still not balanced
C4H10 + O2 --> 4CO2 + 5H2O Now the H is balanced, let's recount
(4C, 10H, 2Oxygen) --> (4C, 8+5Oxygen, 10H) O is still not balanced
C4H10 + (13/2)O2 --> 4CO2 + 5H2O Now the O is balanced
(4C, 10H, 13Oxygen) --> (4C, 13Oxygen, 10H)
But because 13/2 is a fraction, we want to eliminate that by multiplying every reactant and product by 2 (the denominator).
2C4H10 + 13O2 --> 8CO2 + 10H2O Now it's completely balanced!
(8C, 20H, 28Oxygen) --> (8C, 28Oxygen, 20H) Yayy! It's balanced.
Now, 2 mol C4H10 produces 8 mol CO2.
So 1 mol C4H10 produces 4 mol CO2.
Why is a pyramid shape used to represent the energy in an Ecosystem?
Answer:
An energy pyramid shows the flow of energy at each trophic level in an ecosystem. A pyramid shape is used because energy is lost at each trophic level when organisms use it up.

What are the four ions formed when sodium chloride undergoes electrolysis?
Answer: The four ions formed are [tex]H^+[/tex] , [tex]OH^-[/tex] , [tex]Na^+[/tex] and [tex]Cl^-[/tex]
Explanation:
Electrolysis is the process where electricity is used to drive chemical reactions.
In the electrolysis of aqueous solution of sodium chloride, hydrogen gas produces at the cathode which is a negative electrode and chlorine gas produces as the anode which is a positive electrode and the sodium hydroxide remains dissolved in the solution.
The reactions will be :
[tex]NaCl\rightarrow Na^++Cl^-[/tex]
[tex]H_2O\rightarrow H^++OH^-[/tex]
Hence, electrolysis of an aqueous solution of sodium chloride lead to the formation of four ions,[tex]H^+[/tex] , [tex]OH^-[/tex] , [tex]Na^+[/tex] and [tex]Cl^-[/tex]
2. How much force, in g cm / s2 , is exerted by a golf ball described in problem 1 striking a tree while accelerating at 20 cm / s2 ? Show how you can solve this problem without knowing that F = m a. Explain your solution.
Answer:
F = 1000 g cm/s²
Explanation:
Let the weight of 1 ball is 50 gram
Acceleration, a = 20 cm/s²
We need to find the force exerted by a golf ball. We know that,
F = ma
So,
F = 50 g × 20 cm/s²
F = 1000 g cm/s²
So, the required force is 1000 g cm/s².
When white light passes through a prism, what can be discovered?
A)
White light is made invisible by passing through prisms.
B)
White light is made brighter by passing through prisms.
White light is made of a spectrum of various colors.
D)
White light gets hotter when it passes through prisms.
Answer:
White light is made of a spectrum of various colors.
Explanation:
As light passes through a prism, it is bent, or refracted, by the angles and plane faces of the prism and each wavelength of light is refracted by a slightly different amount. ... As a result, all of the colors in the white light of the sun separate into the individual bands of color characteristic of a rainbow.

Which organism in the food chain is
responsible for transforming radiant
energy into chemical energy?
Grass->Prairie Dog -> Coyote -> Soil Bacteria
Answer:
The organism in the food chain responsible for transforming radiant energy into chemical energy is;
Grass
Explanation:
Radiant energy is the energy present in electromagnetic waves which carry photons that may be considered as energy packets. It is an energy present in the Sunlight, which is an electromagnetic waves, and it is the energy in the electromagnetic waves that plants convert to chemical energy for food in the process known as photosynthesis as follows;
6CO₂ + H₂O + Radiant energy → C₆H₁₂O₆ + 6O₂
Therefore the organism in the food chain responsible for transforming radiant energy into chemical energy is the plant, grass

Which of the following correctly describes the difference (on average) between an electron in a 2s orbital and an electron in a 3s orbital?
Answer:
C: electrons is the 3s orbital are higher than those in the 2s orbital
Explanation:
Looking at the options, the correct one is that the electrons in the 3s orbital will possess more energy than those in the 2s orbital. This is because the the 2s orbitals will be filled with electrons first before the 3s orbital.
Also from basics we know that the energy of an orbital increases as the quantum number increases.

There are only 90 naturally occurring elements on Earth but there are millions of different substances explain how this is possible and describe how it applies to at least three examples
Answer:
See explanation
Explanation:
While it is true that there are only about 90 naturally occurring elements, these elements are capable of combining with each other to form millions of substances.
Most of the substances that we see around us today result from a combination of one or more of these naturally occurring elements.
Let us look at three examples;
The carbohydrate in food is composed of carbon, hydrogen and oxygen
The stainless steel materials we use are composed of iron, carbon and other trace elements
Glass is made up of silicon, oxygen and other elements
Only 90 naturally occurring elements capable of combining with each other to form millions of substances.
Compounds:
When two or more elements combine in a certain ratio to form a molecule.
For example-
Water is made up of two hydrogen and one Oxygen ration is 2:1.
If hydrogen and Oxygen combine inn 2:2, they for Hydrogen peroxide.
Water gives life and Hydrogen peroxide can kill a person.
Other examples are,
The carbohydrate in food is composed of carbon, hydrogen and oxygen. The stainless steel is made up of iron, carbon and other trace elements. Glass is composed of silicon, oxygen and other elements.Therefore, only 90 naturally occurring elements capable of combining with each other to form millions of substances.
