The mole ratio O₂ to NH[tex]_3[/tex] in the reaction 4 NH[tex]_3[/tex]+50[tex]_2[/tex] → 4 NO + 6 H₂O is 5:4. Mole is one of the International System of Units.
What is mole?A mole is merely a measuring unit. In reality, it is one of the International System of Units' seven foundation units (SI). When basically determines are insufficient, new units are created.
Chemical reactions frequently occur at levels that use grams would be inappropriate, but using actual figures of atoms/molecules/ions would also be misleading. As a result, scientists devised the mole could bridge the divide between extremely small and extremely huge numbers. The mole ratio O₂ to NH[tex]_3[/tex] in the reaction 4 NH[tex]_3[/tex]+50[tex]_2[/tex] → 4 NO + 6 H₂O is 5:4.
Therefore, the mole ratio O₂ to NH[tex]_3[/tex] in the reaction 4 NH[tex]_3[/tex]+50[tex]_2[/tex] → 4 NO + 6 H₂O is 5:4.

Your answer is: Mass Number
Explanation:
what type of digestion uses the various secretions of the gi tract to break down foods?
Chemical digestion reduces food into smaller molecules that the body may absorb using the various GI tract secretions.
What is GI tract?The system of organs in the body that digests and absorbs food is known as the GI tract, or gastrointestinal tract. The mouth, oesophagus, stomach, small intestine, large intestine, rectum, and anus are all parts of the GI tract.
The two forms of digestion that take place in the gastrointestinal system are mechanical and chemical. By chewing and grinding, food is physically broken down during mechanical digestion.
Gastric juices, pancreatic juices, bile, and intestinal juices are among the secretions involved in chemical digestion. The hydrochloric acid and the pepsin enzyme found in the stomach's gastric secretions help break down proteins into smaller peptides. Trypsin and chymotrypsin, two enzymes that continue the breakdown of proteins, as well as lipases and amylases that break down lipids and carbs, are all present in pancreatic secretions.
Bile, which is created by the liver and kept in the gallbladder, emulsifies lipids and aids in balancing the stomach's acidic chyme. The final step in the breakdown of carbs, proteins, and lipids into their smallest absorbable units is completed by additional enzymes found in digestive fluids.

which is true about the structure of the atom? select the correct answer below: most of the mass is outside the nucleus. most of the atom is empty space. electrons are found inside the nucleus. neutrons are found outside the nucleus.
Most of the atom is empty space is true about the structure of the atom. Option B is correct.
Atomic structure will refers to the structure of an atom which is comprising a nucleus (centre) in which the protons (positively charged) as well as neutrons (neutral) are present. The negatively charged particles known as electrons which revolve around the centre of the nucleus.
The majority of the mass of an atom is concentrated in its nucleus, which is comprised of protons and neutrons. Electrons occupy the space around the nucleus, forming a cloud-like electron cloud that takes up much more space than the nucleus. Neutrons are found inside the nucleus, along with protons.

a mixture of argon and mercury vapor used in advertising signs emits light of wavelength 670 nm. calculate the energy change resulting from the emission of 1.00 mol of photons at this wavelength.
The energy change resulting from the emission of 1.00 mol of photons at a wavelength of 670 nm is 2.45 x 10^5 J.
The Energy Change of Photon EmissionThe energy change resulting from the emission of photons can be calculated using Planck's equation, E = hc/λ, where h is Planck's constant, c is the speed of light, and λ is the wavelength of the light. By substituting the values for these variables and multiplying them by Avogadro's number, we can find the energy change resulting from the emission of a certain amount of photons at a specific wavelength. In the case of a mixture of argon and mercury vapor used in advertising signs that emits light at a wavelength of 670 nm, the energy change resulting from the emission of 1.00 mol of photons is 2.45 x 10^5 J. This calculation highlights the relationship between the energy of photons and their wavelength and demonstrates how the energy of a specific photon emission can be determined.

which scientist is responsible for the theory that explains why properties of elements recur in a periodic fashion
The scientist responsible for the theory that explains why properties of elements recur in a periodic fashion is Dmitri Mendeleev.
According to Dmitri Mendeleev and Lothar Meyer, who separately formulated the periodic law, "when the elements are organised in order of increasing atomic mass, certain sets of properties recur periodically." John Newlands noticed a pattern when he arranged the elements according to their atomic mass, or weight. He discovered that every eighth element appeared to have the same qualities. The periodic law and a periodic table provided by Mendeleev served as the basis for the creation of the present periodic table. Mendeleev claimed that an element's periodic characteristics are a periodic function of its atomic number.

what are the weathering products of these common minerals: quartz, feldspar, amphibole, pyroxene, biotite, muscovite?
The weathering products of the following minerals are:
Quartz: silica gel; Feldspar: clay minerals (such as kaolinite); Amphibole: iron and magnesium-rich clay minerals; Pyroxene: iron and magnesium-rich clay minerals; Biotite: iron and magnesium-rich clay minerals; Muscovite: aluminum-rich clay minerals.
Weathering is the process by which rocks and minerals are naturally broken down and altered due to exposure to environmental factors such as water, air, and temperature changes. Over time, these minerals can undergo chemical reactions that cause them to change into new substances.
Quartz: Quartz is one of the most abundant minerals on Earth and is relatively resistant to weathering. However, over time, water and other natural forces can cause it to break down into silica gel, a soft, sponge-like material.
Feldspar: Feldspar is a common mineral found in many types of rock, including granite and basalt. When exposed to weathering, feldspar breaks down into clay minerals, such as kaolinite, which are rich in aluminum and silicon.
Amphibole: Amphiboles are a group of minerals that contain iron, magnesium, and other elements. When exposed to weathering, amphiboles break down into iron and magnesium-rich clay minerals, which can then mix with other minerals and organic materials to form soils.
Pyroxene: Pyroxenes are a group of minerals that are similar in composition to amphiboles, and they also break down into iron and magnesium-rich clay minerals when exposed to weathering.
Biotite: Biotite is a type of mica mineral that is commonly found in many types of rock, including granite and basalt. When exposed to weathering, biotite breaks down into iron and magnesium-rich clay minerals, which can then mix with other minerals and organic materials to form soils.
Muscovite: Muscovite is a type of mica mineral that is abundant in many types of rock, including granite and gneiss. When exposed to weathering, muscovite breaks down into aluminum-rich clay minerals, which can then mix with other minerals and organic materials to form soils.
