Flour, water, salt, and yeast are mixed, given time to react, and then baked. the product is a brown loaf of bread with many tiny holes from air bubbles. compare the properties of the products and the reactants.

The difference between reactants and product is in terms of Consistency, Porosity , Colour ,  Texture

Explanation:

There are following changes in the properties of the products and the reactants.

a) Consistency - The mixture of reactant was in the form of semi solid while the product i.e the baked cake is in the form of solid.

b) Porosity - The baked bread is comparatively more porous in structure as compared to the reactants.

c) Colour - Mixture of reactant are of light  color while product is dark brown in color

d) Texture - the texture of mixture of reactant is smooth while that of baked bread is partially rough.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.

kelp are large brown algae that live in cool, relatively shallow waters close to the shore. they grow in dense groupings much like a forest on land. these underwater towers of kelp provide food and shelter for thousands of fish, invertebrates, and marine mammal species.
