Back injuries can be crippling and severely limit one’s function and quality of life.
How would your life be affected by a back injury?
What modifications would you have to make to your home if you were confined to a wheelchair?
Which of your hobbies and activities would be affected if you could no longer walk?
A back injury would impact literally every aspect of your life.
You would need to either install a starlit, a lift, or move to a bungalow or bottom floor apartment.
The only hobbies you would be able to complete with no modifications would be what I call stationary hobbies- when you sit and do something, for example, knitting or sewing. However, some sports can be altered to allow for those in a wheelchair to play.
what is the relationship between temperature and pressure pls
Answer:
When the temperature of a system goes up, the pressure also goes up, and vice versa. The relationship between pressure and temperature of a gas is stated by the Gay-Lussac's law.
Answer:
We find that temperature and pressure are linearly related, and if the temperature is on the kelvin scale, then P and T are directly proportional (again, when volume and moles of gas are held constant); if the temperature on the kelvin scale increases by a certain factor, the gas pressure increases by the same factor.

Most lakes have rivers flowing out of them, carrying water to the ocean. However, some
lakes, including Great Salt Lake and the Dead Sea, have no outlet. Water flowing into
these lakes leaves only through evaporation. Considering that the water flowing into the
lakes contains many dissolved substances, how does the lack of an outlet affect the
composition of these lakes? What would you expect to happen after many more years
of inflow and evaporation?

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.
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.

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.

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.

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.:

Copperhead snakes can reproduce both sexually and asexually. which option describes a situation where sexual reproduction is more advantageous for the copperhead snake.
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.
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.

Which statement describes what a thermos does?
A. A thermos makes things warmer
B. A thermos stops heat transfer
C. A thermos makes things cooler
D. A thermos slows heat transfer
A thermos slows down the process of heat transfer as it minimizes the process of conduction and convection.
What is conduction?
Conduction is defined as a process as a means of which heat is transferred from the hotter end of the body to it's cooler end.Heat flows spontaneously from a body which is hot to a body which is cold.
In the process of conduction,heat flow is within the body and through itself.In solids the conduction of heat is due to the vibrations and collisions of molecules while in liquids and gases it is due to the random motion of the molecules ,
When conduction takes place, heat is usually transferred from one molecule to another as they are in direct contact with each other.There are 2 types of conduction:1) steady state conduction 2) transient conduction.According to the type of energy conduction is of three types:
1) heat conduction
2) electrical conduction
3)sound conduction
