What type of energy does each ball have before it falls
why does the second row of the periodic table have 8 elements
short asnwer:
here are 8 elements in period 2 because all those elements have electrons in the second shell and no electrons in the third shell.
Explanation:
There are certain rules for arranging atoms in shells 1) Maximum number of electrons in a shell is given by the formula 2n^2. 2) The outermost ( valence) shell can accomodate only 8 electrons.

5. Molds and bacteria contain hydrolytic enzymes used to breakdown proteins,
lipids, etc.
a) (5 Points) Why does food not spoil as fast when it is refrigerated as it
would at room temperature?
b) (5 Points) Meat begins to feel slimy and it smells when it is spoiled due to
a decomposition reaction with oxygen and carbon dioxide. Why would
meats spoil less rapidly when left unsliced?
Answer:Temperature affects storage time and food deteriorates faster at higher temperatures. Microorganisms grow rapidly at room temperature . Thus to slow microbial growth, enzymatic and oxidative processes, food must be stored at room temperature.
Due to decomposition reactions with oxygen or carbon dioxide in the air, meat begins to feel slimy and smell spoiled. ... Because of its smaller surface area, the unsliced meat would have less collisions and therefore, a slower reaction rate.

C3H8 (g) + 5 O2 (g)
->
3 CO2 (g) + 4 H2O (9)
1. Use stoichiometry to determine how many moles of O2 are needed
to completely react with 2.25 moles of C3H8.
Answer: 11.25 moles of [tex]O_2[/tex] will be required to completely react with 2.25 moles of [tex]C_3H_8[/tex].
Explanation:
The balanced chemical equation is:
[tex]C_3H_8(g)+5O_2(g)\rightarrow 3CO_2(g)+4H_2O(g)[/tex]
According to stoichiometry :
1 mole of [tex]C_3H_8[/tex] require = 5 moles of [tex]O_2[/tex]
Thus 2.25 moles of [tex]C_3H_8[/tex] will require=[tex]\frac{5}{1}\times 2.25=11.25moles[/tex] of [tex]O_2[/tex]
Thus 11.25 moles of [tex]O_2[/tex] will be required to completely react with 2.25 moles of [tex]C_3H_8[/tex].
9. Do all enzymes function at the same pH?
Each enzyme has an optimum pH but it also has a working range of pH values at which it will still work well. This depends on the type of enzyme. The enzyme pepsin breaks down proteins in the acidic conditions of the stomach. ... Catalase has an optimum pH of 9 and a working range of between pH 7-11. Hope this was helpful

What is true about constructive interference?A.Amplitudes in the opposite direction interfere to make larger waves.B.Amplitudes in the same direction interference to larger waves.C.Amplitudes in the same direction interference to make smaller waves.
Answer:
B. Amplitudes in the same direction interference to larger waves
Explanation:
This is because constructive interference is the addition of waves to form a larger wave. In constructive interference, waves with amplitudes moving in the same direction add to form a larger wave.

The movements of what over time affected the global patterns of winds and ocean currents, which slowly changed climates
Answer: movement of continent
Explanation:
The Movement of Continents affects the global patterns of winds and ocean currents, which slowly changes climates.
We should note that the ocean currents moves water from the equator and moves them toward the poles and vice versa. This therefore leads to the regulation of ocean currents. This in turn, lead to changes in the climates.

Colourless substances can be followed by the use of fluorescent adsorbents. Ultra-violet light of a wavelength absorbed by the adsorbed substance is employed. The part of the column containing adsorbed substance then appears as a dark band.
1. Sequence Order the path of a sound wave
from when it is produced by a source until
it is interpreted by the brain
Answer:1. The sound waves arrive at the pinna (auricle), the only visible part of the ear.
2. Once the sound waves have passed the pinna, they move into the auditory canal (external
acoustic meatus) before hitting the tympanic membrane (eardrum).
3. Once the sound waves reach the tympanic membrane, it begins to vibrate and they enter
into the middle ear.
4. The vibrations are transmitted further into the ear via three bones (ossicles): malleus
(hammer), incus (anvil), and the stapes (stirrup). These three bones form a bridge from
the tympanic membrane to the oval window.
5. Once sound passes through the oval window, it enters into the cochlea in the inner ear.
6. Hair cells in the organ of Corti (within the cochlea) are stimulated which in turn
stimulates the cochlear branch of the vestibulocochlear nerve.
7. The cochlear nerve then transmits electrical impulses to the auditory region of the brain
in the temporal lobe.

PLS I WILL GIVE YOU BRAINLY What effect I think this new bacteria will have on patient 23's overall health
Answer:
Gut bacteria are an important component of the microbiota ecosystem in the human gut, which is colonized by 1014 microbes, ten times more than the human cells. Gut bacteria play an important role in human health, such as supplying essential nutrients, synthesizing vitamin K, aiding in the digestion of cellulose, and promoting angiogenesis and enteric nerve function. However, they can also be potentially harmful due to the change of their composition when the gut ecosystem undergoes abnormal changes in the light of the use of antibiotics, illness, stress, aging, bad dietary habits, and lifestyle. Dysbiosis of the gut bacteria communities can cause many chronic diseases, such as inflammatory bowel disease, obesity, cancer, and autism. This review summarizes and discusses the roles and potential mechanisms of gut bacteria in human health and diseases.

Sand is composed of silicon dioxide SiO2. A 210 gram sample has how many moles?
The number of moles of 210 gram sample of sand contains 3.5 moles of mole of SiO₂
Sand is composed of silicon dioxide (SiO₂).
Therefore, let's calculate the molecular mass of SiO₂ . Therefore,
Molecular mass of SiO₂The molecular mass of the compound is the sum of the atomic mass of the compound.
SiO₂ = 32 + (16 × 2) = 28 + 32 = 60 g/molTherefore,
60 g = 1 mole of SiO₂
210 g = ?
cross multiply
number of moles = 210 / 60
number of moles = 21 / 6
number of moles = 3.5 moles
