No, his digestive system is breaking down starch molecules, but his respiratory system may not be working properly.

Oat starch which is mainly stored in the oat endosperm is the most abundant carbohydrate component of oats, and its content varies between 40-50% depending on the variety and growing conditions. Sayer and White 2011. Starch after extraction of oat amylose content lipids was determined by Gudmundson and Eliasson.

Whole grain oats contain large amounts of valuable nutrients such as protein starch unsaturated fatty acids, and dietary fiber in soluble and insoluble fractions. Starch is composed of two glucose polymers amylopectin, and amylose which together form insoluble semi-crystalline starch granules. Both polymers are composed of conjugated glucan chains connected by branch points, but their structure and biosynthesis differ.

In mercuric oxide percent by mass of mercury is 93 %.

The mercuric oxide molecular formula is HgO. When mercury is reacted with oxygen, then it forms the product mercuric oxide. Mercuric oxide has a molecular mass of 216 g/mol. It has a melting point of 500°C.

The balance equation for the reaction of decomposition of mercury oxide into mercury and oxygen is,

[tex]2HgO (s)→ 2Hg (l) + O _{2}(g)[/tex]

Mass of mercury oxide = 28.4 g

Mass of the oxygen = 2 g

In mercuric oxide percent by mass of mercury is,

[tex]Mass ℅= \frac{Mass \: of \: Mercury }{Mass \: of \: Mercury \: oxide} \times 100[/tex]

[tex]= \frac{28.4 - 2}{28.4} \times 100[/tex]

= 93 %

Therefore, in mercuric oxide percent by mass of mercury is 93 %.

Answer:

Mercury

Explanation:

While it is true that most metals are solid at room temperature, mercury is liquid at room temperature hence mercury is often designated as the 'liquid metal'.

Thus, if i find a bottle on the shelf that has no solid in it, only liquid and i know that only pure metals are stored in that area of the laboratory, then i will quickly relabel it as mercury.

Explanations:

I just learned this.

The students were most likely studying French phonemes.

Words are distinguished from each other by respective sounds of the vowels in the word. There are open vowels and there are closed vowels. These exist in every language.

The part of language learning that has to do with the differentiation of pronunciation of sounds is called phonemes. This means that the students were most likely studying French phonemes.

Answer:

the process of separating several mixtures of coal with the process of fractional distillation

Explanation:

The mean mass of the given sample is 39.12g

mass of first sample = 39.75g

mass of second sample = 38.91g

mass of third sample = 37.66g

mass of fourth sample = 39.75g

mass of fifth sample= 39.55g

Total mass of the sample = 39.75 g + 38.91 g+ 37.66 +39.75 g + 39.55 g = 195.62 g

Number of samples = 5

Therefore mean mass of the samples = 39.12g

Answer:

In a Lewis symbol, the symbol for the element is used to represent the atom and its core electrons. Dots placed around the atom are used to indicate the valence electrons. ... In 1916, Gilbert Newton Lewis, an American chemist, suggested that molecules were formed when atoms shared pairs of outer electrons.

Explanation:

Lewis structures show the electrons in the valence shell of atoms in molecules.

Lewis structures are representations of molecules. They consist of the symbol of the element and the valence electrons in the atoms. The electrons are often shown as dots.

The atoms in molecules could be lone pairs or bond pairs. The bond pairs are shown as two dots on an atom. Since lone pairs are localized on an atom, they are shown as dots on the symbol of the atom that contain them.
