What color would the methyl orange indicator turn in a solution with a pH of 2?
Answers
Answer:
The answer is red.
Explanation:
Methyl orange is an organic dye that used as an indicator in acid-base titrations because its color is changed according to pH of the medium (acidic, neutral or basic).Methyl orange is red in acidic solutions, orange in neutral solutions, and yellow in basic solutions.Since pH of the solution is 2, the solution is acidic, the color of the solution will be red.

Answers
Answer:
5.813 mL
Explanation:
You need to use the formula : vol = mass / molar mass x molarity
the molar mass of HCl is 36.46 and the problem gives you the rest of the equation
0.251M x 36.46 = 9.151
53.2g / 9.151 = 5.813 mL

Which formula can be used to calculate the molar mass of ammonia (NH3)?
Molar mass of N + molar mass of H
3 × molar mass of N + molar mass of H
molar mass of N + 3 × molar mass of H
3 × molar mass of N + 3 × molar mass of H
Answers
Answer:
molar mass of N + 3 × molar mass of H
Explanation:
took the test and got it right
Molar mass is the proportion of the mass of the substance to the moles. The molar mass of ammonia is calculated as, the molar mass of N + 3 × molar mass of H. Thus, option c is accurate.
What is molar mass?The molar mass of any substance is the mass in grams divided by the mole of the substance. It is given in g/mol. It is calculated as:
Molar mass = Mass ÷ Moles
In Ammonia there are one nitrogen and three hydrogen atoms, and hence the molar mass is given as,
Molar mass of N + 3 × Molar mass of H
Therefore, option c. molar mass of N + 3 × molar mass of H is correct.

Xavier was conducting a long term study of two populations of butterflies. Both populations had the same number of individuals. Both populations lived in forests that were the same size. Population A lived in a forest that was full of milkweed, the favorite food of this butterfly species. Population B lived in a forest that had limited amounts of milkweed and other foods. Over many years, Xavier found that one of the populations was showing signs of evolutionary change. Their mouth parts were changing and they could get food from new kinds of plants. Which statement explains why one population would be more likely to evolve in response to natural selection? *
a. Population B would be more likely to change because it has a ready supply of food, and only certain butterflies would be able to survive
b. Population A would be more likely to change because it has a ready supply of food and only certain butterflies would be able to survive
c. Population A would be more likely to change because it has a limited amount of food and some butterflies might be better able to get enough food, survive, and reproduce
d. Population B would be more likely to change because those butterflies have a limited supply of food, and butterflies with certain traits might be better able to get enough food, survive, and reproduce.

SEP Analyze Data Which two columns have identical data? What do these two columns suggest about the identity of elements?
Answers
Answer:
The two columns which have identical data are the Atomic number and the number of protons column. This indicates that the atomic number is equivalent to the number of protons in an element.
Explanation:
Atomic Number is given as the number of electrons in an element. As the number of electrons is required to be equal to the number of protons, for the element to exist in the neutral state. This indicates that the atomic number of an element can also be considered equal to the number of protons in that element.

A scientist prepares 500.0 L of gas at 0.921 atm pressure

Answer:

What is ideal gas equation?Ideal gas equation gives idea about the behavior of gases at different conditions and it will be represented as:
PV = nRT, where
P = pressure in atm
V = volume in L
n = moles of gas
R = universal gas constant = 0.082 L.atm/K.mol
T = temperature in K
First we calculate the moles of gas by putting the values according to the first condition in the above equation and we have
n = (0.921)(500) / (0.082)(473) = 11.86 moles
Now we calculate the volume of gas by using the above equation and details of the second condition as:
V = (11.86)(0.082)(293) / (30) = 9.49 L
Hence resultant volume of the gas is 9.49L.

What volume would a sample of gas occupy in LITERS at 0.985 atmospheres and a volume of 3.65 liters if the pressure were raised to 861.0 mmHg?
Answers
Answer:
3.18 L
Explanation:
Step 1: Given data
Initial pressure (P₁): 0.985 atmInitial volume (V₁): 3.65 LFinal pressure (P₂): 861.0 mmHgFinal volume (V₂): ?Step 2: Convert P₁ to mmHg
We will use the conversion factor 1 atm = 760 mmHg.
0.985 atm × 760 mmHg/1 atm = 749 mmHg
Step 3: Calculate the final volume of the gas
Assuming ideal behavior and constant temperature, we can calculate the final volume using Boyle's law.
P₁ × V₁ = P₂ × V₂
V₂ = P₁ × V₁/P₂
V₂ = 749 mmHg × 3.65 L/861.0 mmHg = 3.18 L

Answers
The term for the heaviness on something's surface that exerts a force over an area is pressure. The correct option is b. pressure
Definition of PressureFrom the question, we are to determine the term for the heaviness on something's surface that exerts a force over an area.
Here, we are talking about pressure.
Pressure is defined as the physical force exerted on an object. Mathematically, it is defined as the perpendicular force per unit area.
That is,
[tex]P = \frac{Force}{Area}[/tex]
Where P is the pressure
The units of pressure are Newtons per square meter (N/m²), Pascals etc.
Hence, the term for the heaviness on something's surface that exerts a force over an area is pressure. The correct option is b. pressure
