A) Vinegar is an Acid solution while, Ammonia is a basic solution, so when they react they form a neutral solution,
Therefore this is a neutralization reaction
B) The lower the pH value of a solution, the more acidic it is, and vise versa for basic,
In the table Vinegar has the lowest pH value, of 3. Therefore Vinegar is the most acidic in the table
C) The higher the pH value of a solution, the more basic it is
In the table Ammonia has the highest pH value of 12. Therefore Ammonia is the most basic in the table

Explain your observations in term of how tempurature affects paritcle motion and how liquid changes to a solid
Answer:
See explanation
Explanation:
Temperature is defined as a measure of the average kinetic energy of the molecules of a body.
When a substance is heated, the kinetic energy of its molecules increases as the temperature increases; hence the particles of the substance moves faster with increasing temperature.
When heat is withdrawn from a liquid, the temperature decreases and the average kinetic energy of the molecules decreases. The molecules become less energetic hence the liquid changes into solid

Please Help :))) "A solution with a concentration of 5.7 x 10^-7M would be considered..."
Answer:
The solution is acidic.
Explanation:
To know which option is correct, we shall determine the pH of the solution. This can be obtained as follow:
Concentration of Hydrogen ion [H⁺] = 5.7×10¯⁷ M
pH =?
pH = –Log [H⁺]
pH = –Log 5.7×10¯⁷
pH = 6.2
pH scale reads as follow:
0 to 6.9 => Acidic
7 => Neutral
8 to 14 => Alkaline / basic
The pH of the solution (i.e 6.2) falls between 0 and 6.9 which indicates acidic.
Therefore, the solution is acidic.

Genetic Diversity
• The variation in genes that exists within a species
• Organisms with a large gene pool have a greater
chance of surviving and flourishing than a
population with limited genetic variability.
• Ex: resistance to disease, tolerance to cold
• Darwin termed this process "natural selection."
To the left you can see the variety of genes that exist
in types of fruit. Can you think of another species
that has similar variations?

Answer:
Oranges
Explanation:
Oranges have a lot of genetic diversity within them, since oranges were already well versed in growing in winter months, oranges have gentically modified themselves through natural selection into be able to prouduce in warmer climates. Oranges also have changes in genetics which gives them a lot of gentic diversity that effects their, size, taste, texture, acidity and ability to reproduce.

How do you explain the ability of nonmetals to attract electrons to themselves?
Answer:
When these chemical bonds form, atoms of some elements have a greater ability to attract the valence electrons involved in the bond than other elements. Electronegativity is a measure of the ability of an atom to attract the electrons when the atom is part of a compound. Electronegativity differs from electron affinity because electron affinity
HOPE IT HELPS

it is electronegativity and it increases as you move up and to the right on the periodic table and nonmetals are situated to the top right of the periodic table

Explanation:
What happens to pressure if temperature increases? Pressure increases. Pressure stays the same. Pressure decreases. Temperature has no effect on pressure.
Answer:
Pressure increases
Explanation:
According to Gay-Lussac's law, the pressure of a given amount of gas is directly proportional to the temperature at a given volume i.e.
[tex]P\propto T[/tex]
It means the relationship between the pressure and the temperature is direct.
If the temperature increases, the pressure of the gas also increases. Hence, the correct option is (A).
How many moles of ammonia, NH3, are in 51 grams of NH3?

How much energy is released when 944.3 g of phosphoric acid is produced
P4O10(g) + 6H20(l) -- > 4H3PO4(aq)+424 kj
Answer:
1024.84 Kj
Explanation:
P₄o₁₀(g) + 6H₂O(l) => 4H₃PO₄(aq) + 424Kj
moles H₃PO₄ = (944.3g H₃PO₄) /(97.994g H₃PO₄ /mole H₃PO₄)
= 9.64 moles H₃PO₄
From equation reaction ratios ...
4 moles H₃PO₄ => 424 Kj
9.64 moles H₃PO₄ => (?)
4 moles H₃PO₄/9.64 moles H₃PO₄ = (424Kj)/(?)
Energy Released (Kj) = (424Kj)(9.64moles)/(4moles) = 1021.84 Kj

Can someone double check my work? (Ideal Gas Law Equation)
I am solving for the amount of moles in two gases.
For one, it was 4.75mL at 0.5C (273.65K) and 1.2atm.
n=(1.2*4.75)/(0.0821/273.65)=(5.7/22.456)=0.25361653 moles
For the other gas, it was 4.6mL at 0.5C and 1.2atm.
n=(1.2*4.6)/(0.0821/273.65)=(5.52/22.456)=0.24581403 moles
Please double check these for any errors in math or whatever. Thank you.
I did not see any errors, i may be wrong but what i can see is that it is correct

In a polar bond, ____
are not shared equally between atoms.
Explanation:
Polar Covalent Bonds. A polar
covalent bond exists when
atoms with different
electronegativities share
electrons in a covalent bond.
Consider the hydrogen chloride
(HCI) molecule. Each atom in
HCI requires one more electron
to form an inert gas electron
configuration.

The wave which is having higher frequency is associated with higher energy. In the given wave, the part B is labelling the lowest energy sound.
What are sound waves ?Sound waves are longitudinal mechanical waves passing through a medium. In a longitudinal wave the oscillation of particles is in a direction along the wave propagation.
A sound wave is composed of rarefactions and compressions. The area where, the particles have some separation with lower pressure is called rarefactions.
The area of high pressure where, the oscillating particles are closely packed is called compression of the wave. As the frequency of the wave increases, its energy increases, Therefore, the less frequency part B represent lowest energy sound.
