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'
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.

Which of the following is an example of a Lewis acid?
O A. NaOH
B. CaCO3
O C. BF3
D. NH3
Answer:
C. BF3
Explanation:
The boron in BF3 is electron poor and has an empty orbital, so it can accept a pair of electrons, making it a Lewis acid.
Among the following, an example of a Lewis acid is option C. BF₃ Hence the correct option is (C)
What is Lewis Acid ?A Lewis acid is a chemical species that contains an empty orbital which is capable of accepting an electron pair from a Lewis base to form a Lewis adduct.
The boron in BF₃ is electron poor and has an empty orbital, so it can accept a pair of electrons, making it a Lewis acid.
Boron trifluoride BF₃ behaves as Lewis acid because it is an electron-deficient species and it can accept electron pair.
Here we see Boron configuration is 1s²2s²2p¹ and vacant p-orbital exist, which indicates that mean BF₃ has the tendency to accept lone pair, hence BF₃ is lewis acid.
Therefore, Among the following, an example of a Lewis acid is option C. BF₃ Hence the correct option is (C)

The nutritional energy content (in Calories) present in 86g of broccoli with 6g of carbohydrates, 2.6g of protein, and 0.3g of fat is __________.
Answer:
37.1 calories.
Approximately, 37.1 = 40 calories.
Explanation:
So, without mincing words let's dive straight into the solution to the question above.
We are given the following parameters which are going to help in solving this particular Question.
The mass of broccoli = 86g of broccoli, mass of carbohydrates present = 6g of carbohydrates, the mass of protein present = 2.6g of protein and the mass of fat present = 0.3g of fat.
Therefore, the nutritional energy content (in Calories) = (6 × 4) + (2.6 × 4) + (0.3 × 9) = 10.4 + 24 + 2.7 = 37.1
Hence, the nutritional energy content (in Calories) = 37.1 calories.
Approximately, 37.1 = 40 calories.

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]

Based upon your knowledge of metallic activity, which element would most readily react with water?
A) Li
B) Zn
C) Cu
D) Fe
Answer:
d
Explanation:
Of the given options, Lithium (Li) would most readily react with water.
• The substances that spontaneously go through a chemical reaction with water, as they are highly reducing in nature are known as water reactive substances.
• The alkali metals and the alkaline earth metals are the metals that reacts the most with water.
• In the periodic table, the alkali metals, that is, lithium, sodium, potassium, rubidium, caesium, and francium are the most reactive metals.
• They all react explosively and vigorously with cold water leading to the displacement of hydrogen.
• The alkaline earth metals are the second most reactive metals in the periodic table apart from Be, which does not react with water.
Thus, Li is the alkali metal that reacts readily with water.

What will most likely cause a sudden wind to start blowing?
Answer:
wind is just high and low pressure of air, when a high pressure comes and crashes into a low pressure air pocket than it can form a wind storm.
Explanation:
The Uneven heating of the Earth's surface. Earth's rotation and unequal heating of the Earth's surface. air pressure towards regions of lower air pressure. ... air moving from areas of high pressure to areas of low pressure.
This is what will most likely cause a sudden wind to start blowing.

How many molecules are present in 0.336 mol of acetylene (C2H2)?
Answer:
The answer is 26.03728. We assume you are converting between grams C2H2 and mole. You can view more details on each measurement unit: molecular weight of C2H2 or mol This compound is also known as Acetylene. The SI base unit for amount of substance is the mole.
Explanation:
The solution is 26.03728. We assume you are converting between grams C2H2 and mole. You could view more information on each size unit: molecular weight of C2H2 or mol This compound is also called Acetylene. The SI base unit for the quantity of the substance is the mole.
Is C2H2 a molecule?The C2H2 molecule is product of sigma-bonds and pi-bonds, with a bond attitude of one hundred eighty ranges. This linear molecular geometry is similar to that of CO2 (Carbon dioxide), which is likewise a non-polar compound.
C2H2 has a linear molecular geometry because all the atoms are symmetrically aligned inside the same aircraft. Both Carbon atoms are inside the centre of the C2H2 Lewis structure due to the fact they may be much less electronegative than Hydrogen atoms.
The chemical formulation for acetylene is C2H2 and the chemical composition for carbon monoxide is CO. There are 2 carbon atoms in every acetylene molecule and 1 carbon atom in every carbon monoxide molecule. In each mol of any chemical substance, there are 6.022*10^23 molecules.
