What will happen to an object
that is more dense than the fluid
it is in?
A. It will sink.
B. It will float.
C. It will rise to the surface.
D. It will bounce out of the water.

Answers

If an object has a higher density than the fluid it is in (fluid can mean liquid or gas), it will sink. If it has a lower density, it will float. Density is determined by an object's mass and volume. If two objects take up the same volume, but have one has more mass, then it also has a higher density.

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?

Answers

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.

Answers

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].

The movements of what over time affected the global patterns of winds and ocean currents, which slowly changed climates

Answers

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.

1. Sequence Order the path of a sound wave
from when it is produced by a source until
it is interpreted by the brain

Answers

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.

Answers

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?

Answers

To convert grams to moles you must divide by the molar mass of the molecule
SiO2 molar mass=60.083
210/60.083=3.495
This sample has 3.495 moles of SiO2

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 SiO₂

The molecular mass of the compound is the sum of the atomic mass of the compound.

SiO₂ = 32 + (16 × 2) = 28 + 32 = 60 g/mol

Therefore,

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
