Answer:

pyruvic acid changes to alcohol and carbon dioxide.

Explanation:

In lactic acid fermentation, pyruvic acid from glycolysis changes to lactic acid. This type of fermentation is carried out by the bacteria in yogurt, and by your own muscle cells.

I HOPE THIS HELPS!!!!!

Alcohol and carbon dioxide are produced when pyruvic acid is fermented. The chemical process in which molecules break down is called as fermentation.

Fermentation is an anaerobic chemical process that breaks down molecules like glucose. Pyruvic acid undergoes fermentation to produced lactic acid.

More specifically, fermentation is the foaming that happens during the creation of wine and beer, a procedure that has been around for at least 10,000 years.

Pyruvic acid produced during glycolysis transforms into lactic acid during lactic acid fermentation. Alcohol and carbon dioxide are produced when pyruvic acid is fermented.

Thus, the pyruvic acid when change into lactic acid fermentation obtained alcohol and carbon dioxide.

Answer: The clumps, known as glacier mice, have been found to contain miniature ecosystems

Explanation: Because glaciers are in constant, if slow, motion and are frequently blasted by strong winds.

The clumps, known as glacier mice, have been found to contain miniature ecosystems. And even in freezing temperatures, scientists found, the inhabitants manage to thrive. In high winds glacier mice, which form when clumps of dust and organic debris develop a layer of moss over time, hop across vast sheets of ice.

These included springtails (small insect-like animals), water bears (also known as tardigrades, the only animals known to have survived in space), and roundworms. Globally, glacier mice are rare.

Follow these simple steps to correctly draw a Lewis dot structure: Add up the total number of valence electrons found in the entire compound. Draw the simple structure (skeleton structure) of the compound by connecting everything with single bonds only. Add electrons to all the noncentral atoms. Put any unused electrons on the central atom.

Answer:

Atomic mass of Sodium is 22.9897 u. Note that, each element may contain more isotopes, therefore this resulting atomic mass is calculated from naturally-occuring isotopes and their abundance. The unit of measure for mass is the atomic mass unit (amu). One atomic mass unit is equal to 1.66 x 10 -24 grams.

Answer:

Atom

Explanation:

An atom can absorb or emit one photon when an electron makes a transition from one stationary state, or energy level, to another. Conservation of energy determines the energy of the photon and thus the frequency of the emitted or absorbed light.

In iron (III) oxide, ratio is 4:2

[tex].[/tex]

In Iron (II) oxide, ratio is 1:1

Iron oxides are very important components in most soils as they have major influence on chemical, physical, and microbial properties of soils. Because of their nanoparticulate size (usually 5-200 nm), iron oxides possess large specific surface area.

Generally, iron oxides are prevalent, widely used as they are inexpensive, and play an imperative role in many biological and geological processes. They are also extensively used by humans, eg, as iron ores in thermite, catalysts, durable pigments.

When iron is exposed to moisture or oxygen, oxidation occurs. During this chemical reaction, iron is converted into iron oxide. The iron oxide typically has a reddish, flaky appearance that becomes progressively worse over time.

Answer:

In fact, a fuel cell coupled with an electric motor is two to three is more efficient than an internal combustion engine running on gasoline.

Explanation:

Because hydrogen has a low volumetric energy density, it is stored onbaord a vehicle as a compressed gas to achieve the driving range of conventional vehicles.

Explanation:

Atoms are at their most stable when their outermost energy level is either empty of electrons or filled with electrons. Sodium atoms have 11 electrons. Two of these are in the lowest energy level, eight are in the second energy level and then one electron is in the third energy level.

Any atom is most stable when it’s outermost energy level contains eight electrons.

An atom is defined as the smallest unit of matter which forms an element. Every form of matter whether solid,liquid , gas consists of atoms . Each atom has a nucleus which is composed of protons and neutrons and shells in which the electrons revolve.

The protons are positively charged and neutrons are neutral and hence the nucleus is positively charged. The electrons which revolve around the nucleus are negatively charged and hence the atom as a whole is neutral and stable due to presence of oppositely charged particles.

Atoms of the same element are similar as they have number of sub- atomic particles which on combination do not alter the chemical properties of the substances.
