The path of energy flow from the sun to the humpback whale is as follows:
- Sun---> Plankton ---> Small fishes ---> Humpback whale.
<h3>What is energy?</h3>
Energy is the ability to do work.
The primary source of energy on the earth is the sun.
The energy from the sun is used by producers to produce food on which other organisms depend on.
The energy from the sun gets to the humpback whale through producers such as plankton.
The path of energy flow from the sun to the humpback whale is as follows:
- Sun---> Plankton ---> Small fishes ---> Humpback whale.

Answer:
H3PO4 Mol mass..
= (3 x H1 = 3) + (1 x P31 = 31) + (4 x O16 = 64). = 98g/mol.
a)..Hydrogen: = 3 / 98 = 0.0306 x 100% = 3.06%.
b)..Phosphorus = 31/98 = 0.3162 x 100% = 31.63%.
c)..Oxygen = 64/98 = 0.6531 x 100% = 65.31%.
(Total = 100% H3PO4).
Explanation:
Find the molar mass of all the elements in the compound in grams per mole.
Find the molecular mass of the entire compound.
Divide the component's molar mass by the entire molecular mass.
You will now have a number between 0 and 1. Multiply it by 100% to get percent composition.
1) increase in temperature (heat up). Since the reaction is exothermic because the ΔH value is negative, it means the heat is on the right side of the reaction, in the products; if there is an increase in temperature, the reaction shift away from the heat; to the left.
2) adding any of the product to the reaction, AB or C2 will cause the reaction to shift to the left because if we increase the concentrations of any, the reaction will try to decrease them by shifting away from them and use them as reactants.
3) you could increase the pressure. when pressure increases, the reaction shift to the side with less pressure, or fewer gas moles. this reaction has zero gas moles in the left but 1 in the right. so it shifts left. One way to increase the pressure is to decrease the volume of the container.
Answer:
B) Reactivity
Explanation:
Density, color, melting point, rigidity, fluidity, shape, size etc are all physical properties of any substance.
so, the answer is option b - reactivity.
Answer:
here's your answer
Explanation:
Molar mass of CH3CH2OH = 46.06844 g/mol
This compound is also known as Ethanol.
Convert grams CH3CH2OH to moles or moles CH3CH2OH to grams
Molecular weight calculation:
12.0107 + 1.00794*3 + 12.0107 + 1.00794*2 + 15.9994 + 1.00794
Percent composition by element
Hydrogen H 1.00794 6 13.128%
Carbon C 12.0107 2 52.143%
Oxygen O 15.9994 1 34.730%
