since matter can never be created nor destroyed where do the new substances come from?
Answer:
The Law of Conservation of Matter states that matter can never be created nor destroyed, only conserved. New substances form when bonds break and new bonds form. The chemical properties of the new substances are different from those of the original substances.
What class of enzyme catalyzes addition of oxygen?
Answer:
The answer is Lyase
Explanation:
Any enzyme that catalyzes the addition or removal of the elements water (hydrogen, oxygen), ammonia (nitrogen, hydrogen), or carbon dioxide (carbon, oxygen) at double bonds, as defined in physiology. Decarboxylases, for example, remove carbon dioxide from amino acids, while dehydrases eliminate water.

Can a molecule that has absorbed infrared radiation subsequently emit a photon with a wavelength in the uv region as a result?
yes
no
molecules cannot absorb infrared.
It is not possible that a molecule that has absorbed infrared radiation subsequently emit a photon with a wavelength in the UV region as a result.
Both infrared rays and ultraviolet rays belong to the electromagnetic spectrum. However, the infrared rays are lower in energy than the ultraviolet rays. Hence, infrared rays have a longer wavelength than ultraviolet rays.
This implies that it is not possible that a molecule that has absorbed infrared radiation subsequently emit a photon with a wavelength in the UV region as a result.

Explain how the strongest type of intermolecular force in liquid HF arises
Answer:
The fairly positive hydrogen on one HF molecule will be attracted to one of these lone pairs on a nearby HF molecule. This is a hydrogen bond. Hydrogen bonds are attractions between a δ+ hydrogen on one molecule and a lone pair on a very electronegative atom (N, O or F) on another molecule.

After incubation of a set of O/F glucose tubes, the tube without mineral oil turned yellow, while the tube with mineral oil remained green. What does this indicate?
It might indicate NO fermentation and oxidation of glucose occurred. An oxidative organism breaks down glucose in presence of Oxygen, while a nonoxidative organism can break down glucose in absence of oxygen.
An Oxidation-Fermentation (OF)-glucose test is a microbiological test to determine how an organism is able to break down glucose.
In the first tube, a layer of mineral oil is added in order to reproduce anaerobic conditions, whereas this layer is not added to the second tube in order to reproduce aerobic conditions.
When the non-oil tube turns yellow, while the oil tube remains green, it means that the microorganism is oxidative (i.e., the microorganism only can metabolize glucose in presence of oxygen).
If both tubes remain green, it means that the test is negative and no fermentation/oxidation of glucose occurred.
If both tubes turn yellow, then the microorganism is oxidative and fermentative.

A. The elements that have been discovered so far can be found here.
B. It is arranged by the atomic number (number of protons).
Explanation:
About the Answers:
All the elements that have been discovered are on the periodic table. Scientist know that there are still unknown elements and actually predict what they'll be like and what their properties are. The periodic table is arranged by the increasing number of atomic numbers. The atomic number is main identification of elements and is the amount of protons each element has.

A sample of a compound has been analyzed and found to contain the following:

the compound is determined by experiment to be between 62 and 63 g, what are
the empirical and molecular formulas of the compound?
Answer:
CH3O formula, C2H6O2 ACTUAL FORMULA
Explanation:
A sample of a compound has been analyzed and found to contain the following:
38.71% carbon, 9.75% hydrogen, and 51.54% g oxygen. If the molar mass of
the compound is determined by experiment to be between 62 and 63 g, what are the empirical and molecular formulas of the COMPOUND
empitical
take 100 gm of the compound
f O Divide by atomi wt of O to get moles
51.54/ 16.0 = 3.22
now if there is 1 atom of C and one of O, there will be 3 of H, so
CH3O is the empirical formula
the molar mass of the compound is 62-63. the mass of CH3O is
12 + 16 +3 = 31
2 X31 =62
so the compound is 2 times CH3O or C2H6O2

Ethylene glycol (name IUPAC: ethane-1,2-diol) is an organic formulated compound (CH2OH)2.
The currents in our experiment are between 0 and 20 nanoAmperes. How many electrons per second are passing an ammeter if it reads 10 nA
The number of electrons per second passing an ammeter if it reads 10 nA is 6.24 × 10⁹ electrons per second
Since our current reads 10 nA and we require the number of electrons per second passing through the ammeter, 10 nA = 1 × 10⁻⁹ C/s.
Since there are 1.602 × 10⁻¹⁹ C/electron, the number of electrons per second, n = current/electron charge
= 1 × 10⁻⁹ C/s ÷ 1.602 × 10⁻¹⁹ C/electron
= 1/1.602 × 10¹⁰ electrons
= 0.62422 × 10¹⁰ electrons per second
= 6.2422 × 10⁹ electrons per second
≅ 6.24 × 10⁹ electrons per second
So, the number of electrons per second passing an ammeter if it reads 10 nA is 6.24 × 10⁹ electrons per second

Define kinetic energy and thermal energy
Answer:
Kinetic energy is the energy by ethicalness of article's movement while Thermal energy is the inner energy of an item because of the motor energy of its particles.
Explanation:
Answer:
Thermal energy:
Thermal energy is a type of energy that is formed by the vibration of atoms and molecules inside matter. The faster they vibrate, the more energy they contain. They also gain more heat.
Kinetic energy:
Kinetic energy is the mass/energy that is in moving objects. When an object speeds up, it gains more kinetic energy. All moving objects contain kinetic energy. The moving object gains energy due to its motion.
