In the combustion of hydrocarbon, carbon monoxide is formed. What has occured?
Answers
Answer: This is an incomplete combustion reaction.
Explanation:
Combustion reaction is defined as the reaction in which a hydrocarbon produces carbon dioxide gas and water molecule when reacted with oxygen gas. General equation for this reaction is:
Incomplete combustion is also a reaction between oxygen and hydrocarbon in which the products obtained are carbon monoxide, water and carbon. This type of combustion happens when there is insufficient supply of oxygen gas. General equation for this reaction is:
Hence, the hydrocarbon is undergoing an incomplete combustion reaction.

Anything that has physical or real existence is matter. Everything that exists in the known universe manifests itself as matter or energy.
Matter can be liquid, solid or gaseous. Examples of raw: paper, wood, air, water, stone.
Matter is anything that has mass and occupies space.
What is matter?
In science, matter is anything that has mass and occupies space. This means that matter has volume and mass.
Matter is made up of tiny particles called atoms. Atoms are the basic building blocks of matter. They are the smallest units of matter that can exist independently.
The properties of matter are determined by the composition of the atoms that make up the matter. For example, the boiling point of a liquid is determined by the strength of the intermolecular forces between the molecules of the liquid.

B) cellulose is made up of chitin, which is indigestible
C) the bonds holding cellulose subunits together are extremely strong, stronger than in any other macromolecule
D) there are many hydrogen bonds holding the subunits together
Answers
Cellulose is so difficult for most animals to digest because they don’t have the proper enzyme to break the bonds between subunits.
Further explanation
Cellulose
It is a polysaccharide compound which is difficult to be digested by animals because they don’t have the enzyme needed to break it. It has many monosaccharide molecules bind together by glycosidic bond.
Glycosidic bond
It is a covalent bond. It is formed between two monosaccharide with the removal of one water molecule. It is of two types, Alpha (between C-1 of one monosaccharide and C-2 of other monosaccharide) and beta (also between the C-1 of one monosaccharide and C-2 of another monosaccharide). Enzymes are required for breakdown of cellulose. In our body various enzymes are present for the breakdown of carbohydrates but these enzymes can never digest cellulose. Our enzymes are unable to break beta glycosidic bond but they can break the alpha glycosidic bond. A bond is present in glycogen and starch so these can be digested by human beings. It is thought that such enzymes are produced by vermiform appendix. In herbivores the enzymes which are required for the breakdown of cellulose are present in their digestive tracts so they can digest cellulose.
Animal which can digest cellulose
Grazing animals like cattle can digest cellulose because they have symbiotic bacteria in their intestine and these bacteria hep them in digestion because of special enzymes in them.

Any type of metal may join with a non-metal, such as carbon, nitrogen, oxygen, sulfur, phosphorus, and selenium, to create ionic compounds.
What is an ionic compound ?
A chemical compound known as an ionic compound is one that contains ions bound together by the electrostatic forces known as ionic bonding. Despite having both positively and negatively charged ions, or cations and anions, the molecule is generally neutral.
In most cases, ionic compounds are created between metal and nonmetal components. For instance, the ionic compound calcium chloride is made up of the metal calcium (Ca) and the nonmetal chlorine (Cl) (CaCl2).
A nonmetal and a metal can create an ionic bond, which is the attraction between two ions with opposing charges.
Thus, metal are joined with a non-metal, such as carbon, nitrogen, oxygen, sulfur, phosphorus, and selenium, to create ionic compounds.

Answer:
C6H12O2
Explanation:
The first step in accurately deducing the structure/formula of the model is to count the number of carbon atoms, hydrogen atoms and oxygen atoms mentioned in the model. This gives the molecular formula of the compound.
Next, you look at there arrangement of atoms and bonds as stated in the model, this tells us the structure of the molecule and confirms the molecular formula initially deduced.
The structure of the compound is shown below.
Answer:
Your answer would be C6H12O2

The correct answer is C. Non-metals
Explanation:
Krypton is one of the 118 chemical elements that have been identified. Krypton's main characteristics include lack of odor, color, and low reactivity, due to this, this element is classified as a noble gas and in the periodic table is part of the Group 18. Moreover, Krypton is part of the non-metals category that includes elements with low density, melting/boiling point, and conductivity, which are all features exhibit by Krypton as this has low electricity and heat conductivity, low density, low melting point (around -157 °C) and low boiling point (-153 °C). Thus, the category Krypton gas and in general Krypton belongs to is non-metals.
An element is a pure substance made up of only one kind of atom, each of whose nuclei contains the same amount of protons. A substance whose atoms all contain the same number of protons is said to constitute an element; alternatively, all the atoms of a certain element must contain the same number of protons. Here 'Kr' is a non-metal. The correct option is C.
The elements that absorb or gain electrons to generate negative ions are known as non-metals. In their outermost shell, non-metals often have 4, 5, 6, or 7 electrons. High electronegativities are seen in non-metals. This indicates that non-metal atoms exhibit a significant propensity to attract more electrons than they would ordinarily have.
Krypton is a Group 18 rare gas and chemical element with the atomic number 36 and the symbol Kr.
Thus the correct option is C.
