Answer:
to end segregation
Explanation:
National Association for the Advancement of Colored People (NAACP), interracial American organization created to work for the abolition of segregation and discrimination in housing, education, employment, voting, and transportation; to oppose racism; and to ensure African Americans their constitutional rights.
To end segregation was a major goal of the National Association for the Advancement of Colored People when it was formed in 1909. Therefore, the correct option is option B.
What is NAACP?
A group of individuals led by W. E. B. Du Bois, Mary's White Ovington, Moorfield Storey, and Ida B. Wells founded the National Association over the Advancement of Coloured People (NAACP) in 1909 as an interracial effort to advance fairness for African Americans. Roy Wilkins and Thurgood Marshall were among the group's leaders.
"To ensure the equal treatment in politics, schools, society, and the economy of the liberties of all persons as to eliminate ethnicity-based discrimination" is its stated objective for the twenty-first century. Political lobbying, public relations campaigns, and legal team-developed lawsuit strategies are just a few of the national NAACP initiatives.

A 18.5 gram sample of metal was added to a graduated cylinder that had
an initial volume of 45.50 mL. The water level raised to 54.10 mL. Using
this information, calculate the density of the metal. *
Answer:
[tex]d=2.15g/mL[/tex]
Explanation:
Hello there!
In this case, since the density of the metal is computed as shown below:
[tex]d=\frac{m}{V}[/tex]
We need to calculate the volume of the solid by subtracting the final volume and the initial volume of water:
[tex]V=54.10mL-45.50mL\\\\V=8.60mL[/tex]
Thus, we obtain:
[tex]d=\frac{18.5g}{8.60mL}\\\\d=2.15g/mL[/tex]

When the following molecular equation is balanced using the smallest possible integer coefficients, the values of these coefficients are: sodium chloride (aq) silver nitrate (aq) silver chloride (s) sodium nitrate (aq)
Answer:
1 on each compound there
Explanation:
A balanced reaction is a reaction that has the same number of atoms in the reactants and products. If this number is not the same, we need to balance it putting some numbers as coefficients behind the compound or element that needs to be balanced, For example:
NH₃ ------> N₂ + H₂
As you can see in this reaction, we have 1 nitrogen and 3 hydrogens in the reactants, and in the side of products we have 2 of each element. This needs to be balanced. To do this we put a number as coeffcient to balance the atoms. In this case, we can put a number 2 behind the NH₃, so the number of atoms of nitrogen becomes 2:
2NH₃ ------> N₂ + H₂
But this 2, changes the number of hydrogens, we now have 6 (cause 2 * 3 = 6), so, let's balance hydrogen on the products to be 6, putting a 3:
2NH₃ ------> N₂ + 3H₂
Now, the reaction is balanced in each side of the reaction.
Applying the same principle to the reaction of this exercise we have the following:
NaCl(aq) + AgNO₃(aq) ---------> AgCl(s) + NaNO₃(aq)
As you can see, we have the same number of atoms on each side:
Na: 1; Cl: 1; Ag: 1; N: 1; O: 3
So we don't need to balance this reaction, with just putting the number 1 or none, is perfectly balanced.
Hope this helps

The maximum level of lead allowed in drinking water is 15 mg/kg. What is this concentration in units of parts per million?
Lead is a heavy metal that is present in drinking water in specific small amounts. The maximum amount of lead allowed in drinking water in parts per million is 15 ppm. Thus, option A is correct.
What are parts per million?Parts per million (ppm) is the unit of expressing the mass of the substance with respect to the volume of the solution. It is generally used to represent the concentration of the contaminants or chemicals.
Given,
Mass of lead (Pb) = 15 mg
Volume/mass of water = 1 kilogram
The concentration of lead is calculated as,
Mass of Lead x 10⁶ ÷ Mass of water
=15 × 10⁶ ÷ 1000000
= 15 mg/kg
As it is known that 1 ppm = 1 mg/Kg
So, 15 mg/kg = 15 ppm
Therefore, option A. the maximum level of lead allowed in drinking water is 15 ppm.

Oxygen gas, generated by the reaction 2KClO3 (s) 2KCl(s) 3O2 (g) is collected over water at 27°C in a 1.35-L vessel at a total pressure of 1.00 atm. (The vapor pressure of H2O at 27°C is 26.0 torr.) How many moles of KClO3 were consumed in the reaction?
Answer:
[tex]n_{KClO_3}=0.0353molKClO_3[/tex]
Explanation:
Hello!
In this case, according to the experiment, we first realize that the pressure of oxygen is:
[tex]p_{O_2}=1.00atm-26.0/760 atm=0.966atm[/tex]
Next, we compute the moles based off the ideal gas law:
[tex]PV=nRT\\\\n=\frac{PV}{RT}=\frac{0.966atm*1.35L}{0.08206\frac{atm*L}{mol*K}*300K}=0.0530molO_2[/tex]
Thus, since there is 3:2 mole ratio between oxygen and potassium chlorate, we can compute the consumed moles of the latter as shown below:
[tex]n_{KClO_3}=0.0530molO_2*\frac{2molKClO_3}{3molO_2} \\\\n_{KClO_3}=0.0353molKClO_3[/tex]

1.If an organism has a high biological fitness in one habitat, does it mean it will also have a high biological fitness in a different habitat? Explain.
2.Does natural selection produce a change in individuals or populations?
3.Consider a major environmental change. If there are no organisms in a population that have traits that allow them to continue to reproduce and survive, what would most likely happen to that population?
Answer:
1. If an organism has high biological fitness in one habitat, this does not mean it will have high fitness in another. This is because organisms adapt accordingly to their environment. Therefore, since there is variability among habitats, this does not guarantee that the organism will always have high biological fitness.
2. Natural selection produces changes in populations. Individual organisms are directly impacted by it, as it determines their survival rate, but the only genetic changes would occur in a population.
3. If there are no organisms with varying traits in a population, they will likely go extinct after a major environmental change. This is because natural selection will remove all organisms who are unable to survive in the new environment. If the population does not have the variability to survive this, then they will go extinct.
If an organism has a high biological fitness in one habitat, then it doesn't guarantee a high biological fitness in a different habitat; natural selection does change the individual. The population will go extinct if the individuals can't reproduce.
What is the individual survival chance?The individual that lives in an ecosystem can change itself due to natural selection, as natural selection favors the individuals who can survive in the changing environment, and the change in the environment induces the change in the organism. There is no reproductive success if the organisms are reproductively isolated within the population.
Hence, if an organism has a high biological fitness in one habitat, it doesn't guarantee a high biological fitness in a different habitat; natural selection does change the individual. The population will go extinct if the individuals can't reproduce.

How many moles of oxygen are needed to react with 3.24 moles of ammonia?
Answer:
12 mol
Explanation:
You are given a sample of an unknown solution and are tasked with determining the density. The solution is miscible with water, so you cannot use a float test. To complete this task, you begin by obtaining a clean dry beaker and measure its mass on a balance (120.3621 g). You then use a pipet to transfer the liquid into the beaker. The initial reading on your pipet is 4.126 mL and after you have dispensed the liquid the pipet reads 6.518 mL. You then obtain the mass of the beaker with the liquid inside (123.0194 g).
_____g/mL
Answer: 1.11 g/mL
Explanation:
Density = mass/vol
mass 123.0194-120.3621g = 2.6574
vol 6.518-4.126 ml = 2.392

If the initial temperature of a movable cylinder was 50 degrees Celsius
with a pressure of 2 ATM and an initial volume of 5 Liters,
what would the new volume be if the temperature was lowered to O
degrees Celsius and the pressure was reduced to 1 ATM?
Answer:
8.45 L
Explanation:
From the question given above, the following data were obtained:
Initial temperature (T₁) = 50 °C
Initial pressure (P₁) = 2 atm
Initial volume (V₁) = 5 L
Final temperature (T₂) = 0 °C
Final pressure (P₂) = 1 atm
Final volume (V₂) =?
Next, we shall convert celsius temperature to Kelvin temperature. This can be obtained as follow:
T(K) = T(°C) + 273
Initial temperature (T₁) = 50 °C
Initial temperature (T₁) = 50 °C + 273
Initial temperature (T₁) = 323 K
Final temperature (T₂) = 0 °C
Final temperature (T₂) = 0 °C + 273
Final temperature (T₂) = 273 K
Finally, we shall determine the new volume. This can be obtained as follow:
Initial temperature (T₁) = 323 K
Initial pressure (P₁) = 2 atm
Initial volume (V₁) = 5 L
Final temperature (T₂) = 273 k
Final pressure (P₂) = 1 atm
Final volume (V₂) =?
P₁V₁ / T₁ = P₂V₂ / T₂
2 × 5 / 323 = 1 × V₂ / 273
10 / 323 = V₂ / 273
Cross multiply
323 × V₂ = 10 × 273
323 × V₂ = 2730
Divide both side by 323
V₂ = 2730 / 323
V₂ = 8.45 L
Thus, the new volume is 8.45 L
