Answer:
While the Affordable Care Act (ACA) has made health insurance more affordable for ... for the majority of Americans who have coverage through employer-based plans. ... Why Average Americans Cannot Afford Health Care ... Almost half of our nation's income goes to the top 10 percent of the population.
Explanation:
Here are three ideas based on affordability:
Public transportation
Meal planning and cooking at home
Renting textbooks
What is the defination of affordability?Public transportation: Using public transportation such as buses and trains can be a more affordable option compared to owning and maintaining a personal vehicle.
Meal planning and cooking at home: Eating out at restaurants or buying pre-made meals can be expensive, especially if done frequently. Planning meals ahead of time and cooking at home can be a more affordable option.
Renting textbooks: Instead of purchasing new textbooks for each class, consider renting textbooks for the duration of the semester. This can be a more affordable option than buying new textbooks, especially if the textbooks are only needed for a short period.
These ideas are generally less expensive because they involve reducing unnecessary expenses and finding more affordable alternatives. By using public transportation instead of owning a car, you can save on the cost of purchasing and maintaining a vehicle.
Similarly, by cooking at home and renting textbooks, you can avoid the cost of eating out at restaurants and buying new textbooks.

Indicate whether the formation of each ion involved a loss or gain of electrons, and state the number of electrons that were lost
Answer:
The sign of the charge on an ion indicates the number of electrons gained or lost by the neutral atom. An ion with +1, +2 or +3 charge, has lost 1, 2 or 3 electrons respectively. An ion with a -1, -2, or -3 charge has gained 1, 2or 3 electrons respectively.
Note: The question did not state the ions in question.
Explanation:
Ions are formed when neutral atoms gain or lose electrons. There are two types of ions; cations and anions.
Cations are positively-charged ions which are formed when neutral atoms lose electrons. Cations are formed by metallic elements as they have a greater tendency to give up their electrons in order to form ions, i.e. they are electropositive elements. Examples of cations include Na+, Ca²+, Al³+, Fe³+, etc.
Anions are negatively-charged ions which are formed when neutral atoms gain electrons. Anions are formed by non-metallic elements as they have a greater tendency to accept electrons in order to form ions, i.e. they are electronegative elements. Examples of anions include; Cl-, O²-, N³-, etc.

a) increase the temperature
b) decrease the temperature
c) increase the volume
d) decrease the reaction concentration
Answer:
The correct answer is A, "increase the temperature."
Explanation:
By increasing the temperature, it would shift the reaction to the right. All of the other options would either cause the reaction to shift left, or are simply invalid. I hope this helps!
Increase in temperature will increase the yield of the product and cause a shift to the right.
What is an Endothermic reaction?This is the type of reaction in which reactants absorb heat energy from the surroundings to form products.

How much energy must be absorbed by 45.0g of water to increase its temperature from 83 0°C to 303.0°C?
Answer: There will be 41382 J energy must be absorbed by 45.0g of water to increase its temperature from [tex]83.0^{o}C[/tex] to [tex]303.0^{o}C[/tex].
Explanation:
Given: Mass = 45.0 g
Initial temperature = [tex]83.0^{o}C[/tex]
Final temperature = [tex]303.0^{o}C[/tex]
Formula used to calculate heat energy is as follows.
[tex]q = m \times C \times (T_{2} - T_{1})[/tex]
where,
q = heat energy
m = mass of substance
C = specific heat = [tex]4.18 J/g^{o}C[/tex] (here, for water)
[tex]T_{1}[/tex] = initial temperature
[tex]T_{2}[/tex] = final temperature
Substitute the values into above formula as follows.
[tex]q = m \times C \times (T_{2} - T_{1})\\= 45.0 g \times 4.18 J/g^{o}C \times (303.0 - 83.0)^{o}C\\= 41382 J[/tex]
Thus, we can conclude that there will be 41382 J energy must be absorbed by 45.0g of water to increase its temperature from [tex]83.0^{o}C[/tex] to [tex]303.0^{o}C[/tex].

Soda water is water that has bubbles of carbon dioxide in it,
soda water is…
a) mixture
b) a molecule
c) an element
d) a compound
Answer:
it is a mixture.
Explanation:
Soda water is a solution of water (H2O) and carbon dioxide (CO2). It has a variable composition and there are not chemical bonds involved.
There is some chemical reaction between CO2 and H2O, producing some carbonic acid H2CO3. This is what gives a slight acidity to soda water.
The correct option for the given question about Mixtures is Option A) Mixture
Why Soda water is a mixture?A mixture of water (H2O) and carbon dioxide is soda water (CO2). There are no chemical bonds present, and it has a variable composition.
It is also called carbonated water as CO2 is first compressed and then get dissolved in it.
The chemical interaction between CO2 and H2O results in the production of H2CO3, a carbonic acid. This is what gives soda water a little acidity.
If the water is somewhat cold in temperature, gas can dissolve in it. The less soluble gas is, the hotter the water is. Additionally, more gas may dissolve in water at greater pressures for the water and gas combination.
Thus we can conclude that Soda water is a homogenous mixture of water and carbon dioxide.

A 25.0 L tank of nitrogen gas is at 25 oC and 2.05 atm . If the temperature stays at 25 oC and the volume is decreased to 14.5 L , what is the new pressure?
Answer:
[tex]\boxed {\boxed {\sf P_2 \approx 3.53 \ atm}}[/tex]
Explanation:
In this problem, the temperature stays constant. The volume and pressure change, so we use Boyle's Law. This states that the pressure of a gas is inversely proportional to the volume. The formula is:
[tex]P_1V_1=P_2V_2[/tex]
Now we can substitute any known values into the formula.
Originally, the gas has a volume of 25.0 liters and a pressure of 2.05 atmospheres.
[tex]25.0 \ L * 2.05 \ atm = P_2V_2[/tex]
The volume is decreased to 14.5 liters, but the pressure is unknown.
[tex]25.0 \ L * 2.05 \ atm = P_2 * 14.5 \ L[/tex]
Since we are solving for the new pressure, or P₂, we must isolate the variable. It is being multiplied by 14.5 liters and the inverse of multiplication is division. Divide both sides by 14.5 L .
[tex]\frac {25.0 \ L * 2.05 \ atm }{14.5 \ L}=\frac{P_2 *14.5 \ L}{14.5 \ L}[/tex]
[tex]\frac {25.0 \ L * 2.05 \ atm }{14.5 \ L}= P_2[/tex]
The units of liters cancel.
[tex]\frac {25.0 * 2.05 \ atm }{14.5 }=P_2[/tex]
[tex]\frac {50.25\ atm }{14.5 }=P_2[/tex]
[tex]3.53448276 \ atm = P_2[/tex]
The original values of volume and pressure have 3 significant figures, so our answer must have the same.
For the number we found, that is the hundredth place.
3.53448276The 4 in the thousandth place (in bold above) tells us to leave the 3 in the hundredth place.
[tex]3.53 \ atm \approx P_2[/tex]
The new pressure is approximately 3.53 atmospheres.

Answer: When maganese dioxide is added to hydrogen chloride you get water maganese dichloride and chlorine gas then balanced equation is [tex]MnO_{2} + 4HCl \rightarrow 2H_{2}O + MnCl_{2} + Cl_{2}[/tex].
Explanation:
The word equation is given as maganese dioxide is added to hydrogen chloride you get water maganese dichloride and chlorine gas.
Now, in terms of chemical formulae this reaction equation will be as follows.
[tex]MnO_{2} + HCl \rightarrow H_{2}O + MnCl_{2} + Cl_{2}[/tex]
Here, number of atoms on reactant side are as follows.
Mn = 1O = 2H = 1Cl = 1Number of atoms on product side are as follows.
Mn = 1O = 1H = 2Cl = 4To balance this equation, multiply HCl by 4 on reactant side and multiply [tex]H_{2}O[/tex] by 2 on product side. Therefore, the equation can be rewritten as follows.
[tex]MnO_{2} + 4HCl \rightarrow 2H_{2}O + MnCl_{2} + Cl_{2}[/tex]
Hence, number of atoms on reactant side are as follows.
Mn = 1O = 2H = 4Cl = 4Number of atoms on product side are as follows.
Mn = 1O = 2H = 4Cl = 4Since, this equation contains same number of atoms on both reactant and product side. Therefore, this equation is now balanced equation.
Thus, we can conclude that when maganese dioxide is added to hydrogen chloride you get water maganese dichloride and chlorine gas then balanced equation is [tex]MnO_{2} + 4HCl \rightarrow 2H_{2}O + MnCl_{2} + Cl_{2}[/tex].

What is the relative humidity if the dry-bulb temperature is 8˚C and the difference between the wet and dry-bulb temperatures is 6˚C ?
Answer:
39%
Explanation:
The Dry Bulb Temperature (also known as air temperature) is the ambient air temperature.
The Wet Bulb temperature is the temperature of adiabatic saturation.
The relative humidity is the amount of water vapor in the air. The relative humidity can be gotten from the dry bulb and wet bulb temperature. The difference between the wet bulb and dry bulb temperature as well as the dry bulb temperature is used to determine the relative humidity with the help of a Psychrometric Chart
Given that the dry-bulb temperature is 8˚C and the difference between the wet and dry-bulb temperatures is 6˚C. From the chart:
Relative humidity = 39%
