Phototropism is one plant tropisms or plant movements as a reaction to an external stimuli for this case light. There are two types of phototropism namely the positive and negative. Negative phototropism is exhibited by plants that grows away from the light. Examples are Monstera, Philodendron and other tropical vines.

ira [324]
1) Calculate the number of mols,n,  of the substance

n = mass/ molar mass = 326.0 g / 58.45 g / mol = 5.577 moles

2) Calculate the molar heat of fusion as the total heat released by the sample divided by the number of moles

hf = heat released / n = 4325.8 cal / 5.577 moles = 775. 59 cal /mol

The variations in the physical characteristics between different proteins are influenced by the overall amino acid compositions,
pishuonlain [190]

Answer:

Sequence

Explanation:

Physical properties of the proteins are foundation of biological function of them.

A protein molecule is made up from the long chain of the amino acids. Each amino acid is linked to its neighbor by covalent peptide bond. Thus, proteins are also called as polypeptides.

Each protein has unique sequence of the amino acids, exactly same from one molecule to next. Different proteins has its own particular sequence of amino acid. This sequence is responsible for folding and binding of the protein and also its physical characteristics.

If 6. 000 g of sugar is mixed with 9. 000 g of water, what is the concentration in weight percent?.
lbvjy [14]

The concentration in weight percent when 6 g of sugar is mixed with 9 g of water is 40%.

There are several ways to denote the concentration of a solution like

  • Molarity
  • Molality
  • Mass percent
  • Mole Fraction

The formula for calculating mass percent is as follows

Mass per cent = (Mass of solute/Mass of solute + Mass of solvent) x 100%

In the given situation sugar is the solute and water is the solvent.

Putting the given values in the above formula

Mass per cent = (6/6+9) x 100%= 6/15 x 100% = 40%

Hence, the concentration in weight percent when 6 g of sugar is mixed with 9 g of water is 40%.

To know more about "concentration of a solution", refer to the link given below:
