what is the difference between fermentation and alcohol
Answer:
Unlike lactic acid fermentation where-in the end product is lactic acid, the 'waste' material in an alcohol respiration is ethanol (an alcohol) and CO2 (carbon dioxide). Human beings have already perfected the use of this process for commercial purposes like in the production of beer, wine and bread
Explanation:
In alcoholic fermentation, pyruvate changes to alcohol and carbon dioxide. This type of fermentation is carried out by yeasts and some bacteria.
Buckets of paint can be classified as what type of mixture?
Answer:
Homogeneous
Explanation:
Homogeneous mixtures are uniform in composition. They have the same proportion of components throughout. Homogeneous mixtures are called solutions. Sugar, paint, alcohol, gold are all examples of homogeneous mixtures because they look the same throughout.
Choose the electron configurations which are possible for an unexcited atom. Example 1 – 1s22s22p4 Example 2 – 1s22s22p63s23p33d1 Example 3 – 1s22s22p83s1 Example 4 – 1s22s22p63s1
Answer:
Examples 1, 3 and 4
Explanation:
An unexcited atom is an atom in the ground state i.e the atom has it's valence electrons in it's lowest energy level possible. This actually implies the normal electronic configuration of the atom. Thus, examples 1, 3 and 4 have the actual electronic configuration with there valence electrons in the lowest possible energy level.
Example 1: 1S² 2S² 2P⁴
Example 3: 1S² 2S² 2P⁶ 3S¹ (There seem to be a mistake in the question provided, P energy level can only 6 electrons not 8)
Example 4: 1S² 2S² 2P⁶ 3S¹
NOTE: If you take a look at example 2, it will be deduced that the 3P energy level has only 3 valence electrons and the last valence electron jumped to 3d energy level; making that atom appear to be in it's excited state.
what can the shape of a molecule affect?
Answer:
Comrades it's B
Explanation:
You can trust me or not but it will be your fauit if you fail so i say trust me comrade. Glroy to Alpha!
A molecule's shape greatly influences the polarity of the compound, the molecular structure has an impact on molecular characteristics. The shape of a molecule affect the molecule's function. Therefore, option B is correct.
What is molecule ?Based on the environment, the term may or may not include ions that meet this requirement. A molecule is a collection of two or more atoms held together by the attractive forces known as chemical bonds.
Molecule shape play a key role in anticipating how one molecule may interact with another, as well as in determining macroscopic features like melting and boiling points.
Polar substances have higher boiling and melting temperatures, tend to dissolve in other polar compounds, and can either form solids or liquids.
Thus, option B is correct.

If an object has a volume of 3 cm3 and has a density of 9 g/cm3. What is the mass of the object?
3 grams
6 grams
27 grams
81 grams
Answer:
The answer is 27 gramsExplanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volume
From the question we have
mass = 9 × 3
We have the final answer as

we know that it's represented element
thus block also represented by s,p,d,f

Explanation:
The electronic configuration of an element is related to its position on the periodic table.
The links are:
the number of circles in the electronic configuration of an element is represented in the periodic table as the period number that element is situated in
the number of electrons in the outermost shell of an element is represented in the periodic table as the group number that element is situated in
the number of electrons in all shells of an element is represented in the periodic table as the element's atomic numbe

Answer:
A cell cycle is a series of events that takes place in a cell as it grows and divides. ... The cell then leaves interphase, undergoes mitosis, and completes its division. The resulting cells, known as daughter cells, each enter their own interphase and begin a new round of the cell cycle.

Answer:
Read this passage from Through the Looking-Glass.
She looked at the Queen, who seemed to have suddenly wrapped herself up in wool. Alice rubbed her eyes, and looked again. She couldn't make out what had happened at all. Was she in a shop? And was that really—was it really a SHEEP that was sitting on the other side of the counter? Rub as she could, she could make nothing more of it: she was in a little dark shop, leaning with her elbows on the counter, and opposite to her was an old Sheep, sitting in an arm-chair knitting, and every now and then leaving off to look at her through a great pair of spectacles.
“What is it you want to buy?” the Sheep said at last, looking up for a moment from her knitting.
“I don't QUITE know yet,” Alice said, very gently. “I should like to look all round me first, if I might.”
“You may look in front of you, and on both sides, if you like,” said the Sheep: “but you can't look ALL round you—unless you've got eyes at the back of your head.”

Explanation:
When heat is added to matter, the temperature rises. The average kinetic energy also increase and the matter melts.
When matter melts, it turns from a solid to a liquid. So, the melting point of matter is the temperature where it changes from the solid state of matter to the liquid state of matter.

Which answer best describes why water dissolve most salts? Water is polar and salts form ions in solution. Water is nonpolar and salts form ions in solution. Water has the same density as salt Water has a different density than salts
Answer: Water is polar and salts form ions in solution.
Explanation:
According to the concept of “Like dissolves like”, the polar solutes dissolve in polar solvents, and non-polar solutes dissolve in non-polar solvents.
Water being a polar solvent due to large electronegativity difference between hydrogen and oxygen is able to interact with the ions of the solute.
As water molecules are also polar in nature. So, oppositely charged ions interact with each other and dissolve in it.
Water can form hydrogen bonds with most of the substances and hence dissolve them . Thus water is considered as a universal solvent.
Answer: Water is polar, and salts form ions in solution

why do humans pump water from underground?
Answer:
Most wells do not get their water from underground rivers, but instead get the water from aquifers. Aquifers are layers of rock and soil with water flowing through their small pores. ... New water, such as from rain or melting snow, drips down into the ground through the pores and cracks in the rocks and soil.
Explanation:
Answer:
Pumping can affect the level of the water table. Groundwater occurs in the saturated soil and rock below the water table. If the aquifer is shallow enough and permeable enough to allow water to move through it at a rapid-enough rate, then people can drill wells into it and withdraw water.

Newton Second Law of Motion, a = F/m tells us that acceleration (a) can be increased by _-
Answer:
Increasing the force
Explanation:
From Newton's second law of motion, we understand that force is a product of mass and acceleration.
Force = mass x acceleration.
Also, force is directly proportional to acceleration. The more the force applied on a body, the higher the acceleration it produces.
Mass is inversely proportional for force.
