Answer:
Physical and functional properties (gelatinization degree, bulk density, expansion ratio, water absorption index, water solubility index, and sensory characteristics (hardness, crispness, and bowl life) of cereal extrudates were determined.
Wavelength is the
ratio of speed of light and frequency:
wavelength = speed of
light / frequency
where frequency is: (c
is speed of light)<span>
freq = c / wavelength = 3E8/550E-9 = 5.45E14 Hz
We know that photons have energy E = hf = 6.626E-34 Js * 5.45E14
Hz = 3.61 E-19 J
Therefore if it has 4.40 mJ of energy, the pulse has:
<span>4.40E-3/3.61E-19 = 1.22E16 photons</span></span>
The chemical equation is unbalanced and synthesized.

What is a chemical equation?</h3>
A chemical equation is described as the symbolic representation of a chemical reaction in the form of symbols and chemical formulas.
In a chemical equation, the reactant entities are given on the left-hand side and the product entities is shown on the right-hand side with a plus sign between the entities in both the reactants and the products, and an arrow that indicates towards the products to show the direction of the reaction.
We can conclude that in the chemical equation shown is unbalanced because both amounts of the individual elements and compounds do not reflect on the reactant and product side.

The complete question is below:
After learning about the law of conservation of mass, Sammy became interested in balancing equations. He knew that the symbol for aluminum was Al and silver tarnish was Ag2S. He also knew that mixing the two chemicals yielded pure silver, or Ag, in an aluminum sulfide solution. Here is the equation showing this reaction:
3 Ag2S + 2 Al → 6 Ag + Al2S3
This equation is (synthesis / unbalanced / replacement / balanced), and it represents a(n) (unbalanced / balanced / synthesized / replaced) chemical reaction.

Answer:
39.998
Explanation:
Hello, have a periodic table handy!
Molar mass is the molecular weight of a compound; sum of all of the mass in grams (from the periodic table) from each and specific atom.
In the periodic table, the molecular weight of an atom is usually shown on the bottom of the element.
In NaOH, there are three atoms in that compound. Na (sodium), O (oxygen), and H (hydrogen).
For Na, the molecular weight is 22.99
For O, the molecular weight is 16.00
For H, the molecular weight is 1.008.
Add all of those values up together to get the molar mass of NaOH being 39.998
