Polysaccharide structure can be varied by differences in ________.
Scilla [17]

Answer:

monomers of MONOSACCHARIDES

Explanation:

Polysaccharides are large molecules formed from chains of POLYMERS linked together by glyosidic bonds. <u>MONOMERS are small sub units that formed polymers, they are therefore the building block of a polysaccharides.  The monomers of polysaccharides are called monosaccharid</u>es (1 sugar molecule.) when two of these are joined together they formed disaccharides (two sugars.)

Polysaccharides are fromed by joining  together condensation, (loss of water molecules,)  of mutiple monosaccharides units and the reversal of this to add water molecules to sepate them to monosaccharies is  sugar Hydrolysis.

Example of polysaccharides are starch, glycogen cellulose

Example of monosaccharides are glucose, galactose.

Disaccharides are common table sugar, sucrose, maltose, lactose

A gas delivers 874 J of heat and then has 159 J of work done upon it. The change in internal energy of the gas is
Nesterboy [21]

The change in internal energy of this gas sample is equal to: c. 715 J.

<u>Given the following data:</u>

  • Quantity of heat = 874 J.
  • Work done = 159 J.

<h3>What is the First Law of Thermodynamics?</h3>

Mathematically, the the First Law of Thermodynamics is given by this formula:

\Delta H = Q-W

Where;

  • \Delta H is the change in internal energy.
  • Q is the quantity of heat.
  • W is the work done.

Substituting the parameters into the formula, we have;

\Delta H =874-159\\\\\Delta H = 715

Change in internal energy (ΔH) = 715 Joules.
