<span>4.66 x 10^-19 Joules
The energy of a photon is
E=hf
Where
E = Energy
h = Planck's constant (6.62607004Ă—10â’34 J s)
f = frequency of photon.
So plug in the known values
E = 6.62607004Ă—10â’34 J s * 7.03 x 10^14 1/s
E = 4.65812724x10^-19 J
Since we only have 3 significant figures, the rounded result is
E = 4.66x10^-19 J</span>

Explanation:
Name Type of sugars
Sucrose Disaccharide
Sucrose, also called table sugar with molecular formulae C12H22O11 is a disaccharide composed of two monosaccharides ( 50%glucose + 50% fructose.).
Lactose Disaccharide
Lactose with molecular formula C12H22O11, found in milk is a disaccharide composed of two monosaccharides (galactose and glucose).
Fructose Monosaccharide
Fructose with molecular formulae C6H12O6 is a natural sugar mostly found in fruits.
Starch Polysaccharide
Starch ,a complex carbohydrate with molecular formula (C6H10O5)n, is a Polysaccharide containing many units of glucose joined together by 1,4 linkages. Sources of starch can be found in the parts of plants( roots, tubers etc).
Glucose monosaccharides
Glucose, is a simple sugar (monosaccharides) with the molecular formula C6H12O6. It is found in parts of plants as well as in humans and known as blood sugar because of its location in the bloodstream.
Answer:
6^3 I believe.
Explanation:
If it's wrong it may be 6^2 because you should square it, but I think it's 6^3
Answer:
Explanation:
Assume the reaction is the combustion of propane.
Word equation: propane plus oxygen produces carbon dioxide and water
Chemical eqn: C₃H₈(g) + O₂(g) ⟶ CO₂(g) + H₂O(g)
Balanced eqn: C₃H₈(g) + 5O₂(g) ⟶ 3CO₂(g) + 4H₂O(g)
(a) Table of enthalpies of formation of reactants and products
(b)Total enthalpies of reactants and products
ΔᵣH° is negative, so the reaction is exothermic.
Answer:
A trigonal pyramid is a tetrahedron with one vacant vertex.
Explanation:
<em>How does a trigonal pyramid differ from a tetrahedron so far as molecular geometry is concerned? </em>
<em>Bond angles in the tetrahedral molecule are 120°, while those for trigonal pyramid are 109.5°.</em> FALSE. Bond angles in the tetrahedral are 109.5°, while those for the trigonal pyramid are slightly lower than 109.5° due to the repulsion of the unshared pair of electrons on the central atom.
<em>A trigonal pyramid is a tetrahedron with two vacant vertex.</em> FALSE.
<em>A trigonal pyramid is a tetrahedron with one vacant vertex.</em> TRUE. This is the geometry of NH₃, in which the central atom is bonded to 3 atoms and has 1 unshared pair of electrons.
<em>Bond angles in the tetrahedral molecule are 109.5°, while those for trigonal pyramid are 120°.</em> FALSE.
<em>A tetrahedron has a square base, while the base of a trigonal pyramid is a triangle.</em> FALSE. Both have a triangular base.
