how does the shape of the periodic table relate to electron configuration?
The shape of the periodic table is related to the electron configuration of elements by the arrangement of periods which can be used to guess the highest energy levels of the atom. Additionally, the group to which an atom belongs is the number of Valence electrons it has.
The periodic table is a systematic arrangement of elements in order of their atomic number with a set of 7 rows called periods and a set of 8 or 18 Columns called Groups.
In essence, the period of an element is a measure of the highest energy level shell of such an element.Additionally, the group of an element is as determined by the number of Valence electrons in the outermost shell of such an element.Ultimately, the s-, p-, d-, and f- group elements are visibly arranged and can be identified from the shape of the periodic table.

three moles of sodium carbonate are mixed with two moles of lead nitrate in aqueous solution, leading to formation of a solid precipitate. how many moles of spectator ions remain in solution, assuming 100% yield of the precipitate?
There are 4 moles of spectator ions that remain in solution.
The equation of the reaction is;
Na2CO3(aq) + Pb(NO3)2(aq) -------> PbCO3(s) + 2NaNO3(aq)
We have to determine the limiting reactant. This is the reactant that yields the least amount of product. Note that the spectator ions are Na^+ and NO3^- that form NaNO3.
For Na2CO3
1 mole of Na2CO3 yields 2 moles of NaNO3
3 moles of Na2CO3 yields 3 × 2/1 = 6 moles of NaNO3
For Pb(NO3)2
1 mole of Pb(NO3)2 yields 2 moles of NaNO3
2 moles of Pb(NO3)2 yields 2 × 2/1 = 4 moles of NaNO3
We can see that Pb(NO3)2 is the limiting reactant.
Since [NaNO3] = [Na^+] = [NO3^-], it follows that there are 4 moles of spectator ions that remain in solution.

what if water didnt have a negative charge?
Explanation:
The water molecule has a tiny negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms due to the unequal sharing of electrons.
Rocks can be classified based on texture. The size of the grains in a rock affects its texture. Coarse-grained rocks have large grains, and fine-grained rocks have small grains.
Rocks formed from magma under Earth’s surface have larger grains than rocks formed from lava on Earth’s surface. This is because magma cools slower underneath the ground than it does above ground.
What kind of rock is this?
A.Igneous
B.Metamorphic
C.Sedimentary
Where would this rock most likely be formed?
A. Along the sides of a volcano
B. On the ocean floor"
C.underneath the Earths surfaces
To which group of rocks would this rock belong?
A. Coarsed-Grained Rocks
B. Fine-Grained Rocks
C. Non-Grained Rocks
1. is Igneous rock
2. is underneath Earths surface
3. is Coarsed-grained

The kind of rocks is igneous rocks formed along the sides of volcano and are coarsed-grain rocks.
What are igneous rocks?
Igneous rocks are one of the three main rock types the other two including sedimentary and metamorphic rocks.These rocks are formed by cooling and solidification of lava or magma.
The magma is derived from partial melts in the planet's mantle or crust.Melting is caused by increase in temperature or decrease in pressure or even change in composition.Solidification occurs either below surface which is called as intrusive rocks or on the surface as extrusive rocks.
They are classified according to their texture,mode of occurrence,chemical composition,geometry and mineralogy of rock.The two important variables for classification are mineral composition and cooling history.

how many valence electrons does alkali metals gain or lose
Answer:
Alkali metals have 1 valence electron on their outer shell. They are more stable when they have 8 valence electrons, so they want to lose that valence electron. They do this by bonding with other elements. When they lose their 1 valence electron, they have a full octet and are therefore stable.:

50. Arrange the following pairs from strongest to weakest
attraction:
a. polar molecule and polar molecule
b. nonpolar molecule and nonpolar molecule
C. polar molecule and ion
d. ion and ion
Arranging the pairs from strongest to weakest attraction :
Nonpolar molecule and Nonpolar molecule ( B )Polar molecule and Polar molecule ( A )Polar molecule and Ion ( C )Ion and Ion ( D )Covalent bonds are the strongest bonds because it involves the sharing of electrons between two binding atoms therefore the atoms are not dissociated easily. Also covalent bonds are divided into ;
Polar covalent bonds ; The shared electrons from each atom involved are unequal therefore it is easier to dissociate polar molecule bonds ( i.e. weaker bond ). Non Polar covalent bonds ; The shared electrons from each atoms are equally therefore it is harder to dissociate nonpolar molecule bonds ( i.e. stronger bond when compared to polar bonds ).While Ionic bonds involves the transfer of electrons from a donor atom to another atom and such bonds are easily broken and it is a weaker bond when compared to Polar and Nonpolar bonds. therefore polar molecule and ion bond pair is stronger than ion and ion pair.
Hence we can conclude that ranking the pairs from strongest to weakest attraction is as follows; Nonpolar molecule and Nonpolar molecule, Polar molecule and Polar molecule, Polar molecule and Ion, Ion and Ion.

what is the strongest intermolecular force to be overcome when ethanol is converted from a liquid to a gas?
Answer:
hydrogen bonding
Explanation:
The strongest among them is hydrogen bonding, and the weakest are London dispersion forces.
The strongest intermolecular force to overcome when ethanol is converted from liquid to a gas is hydrogen bonding.
Intermolecular forces are forces that are a weaker force of attraction than intramolecular forces.
Intermolecular forces are forces between molecules and hold these molecules together.
Hydrogen bonding is an example of intermolecular forces between the OH group in the alcohol.
During the conversion of ethanol from liquid to gas state, hydrogen bonding occurs between the partial negative charge in the oxygen and the partial positive charge in the hydrogen.

at 20°c, a 0.376 m aqueous solution of ammonium chloride has a density of 1.0045 g/ml. what is the mass % of ammonium chloride in the solution? the formula weight of nh4cl is 53.50 g/ml.
At 20°c, a 0.376 m aqueous solution of ammonium chloride has a density of 1.0045 g/ml. The mass percent of the ammonium chloride in the solution is 2.003%.
The number of moles of a substance can be estimated as:
[tex]\mathbf{number\ of\ moles = \dfrac{mass}{molar \ mass}}[/tex]
Given that:
number of moles = 0.376 Mmolar mass of ammonium chloride = 53.50 g/mlMass = number of moles × molar mass
Mass = 0.376 × 53.50
Mass = 20.116 grams
In one mL of ammonium chloride; the grams of ammonium chloride is:
[tex]\mathbf{= \dfrac{20.116 \ grams}{1000 \ mL}}[/tex]
= 0.020116 g/mL
The mass of ammonium chloride in the solution can be computed as:
[tex]\mathbf{=(\dfrac{mass \ of \ NH_4Cl}{density \ of \ the \ solution})\times 100}[/tex]
[tex]\mathbf{=(\dfrac{0.020116 }{1.0045})\times 100}[/tex]

what is the end-product of the beta-amylase reaction?
Answer:
maltose
Explanation:
β-amylase is an enzyme found in fungi, bacteria and plants but not in humans. Unlike α-amylase, β-amylase can only degrade starch from the non-reducing end of the polymer chain by hydrolysis of the second α-1,4 glycosidic bond. The end product is thus maltose, i.e. two glucose units.

A. a new disease develops , so having more genetic variation among there off spring is an advantage.
B. a new type of pray arrives in the environment , so they have more food sources.
C. a short and mild winter makes the environment more livable for them and all the other organisms in the area.
D. they migrate to a new location where prey and shelter are more abundant and easier to find.
Answer:
Answer A:
a new disease develops , so having more genetic variation among there off spring is an advantage.
Not 100% sure but A seems the most likely answer.
Explanation:
The question is asking where sexual reproduction is more of an advantage and I'd say that having more genetic variation would be caused by sexual reproduction and not as much or at all in asexual reproduction.
with B, C, and D. It wouldn't really be an advantage to do one or the other in this context.
