Answer:
[tex] \boxed{ \sf \: 3-propyl-hept-1-yne}[/tex]
Explanation:
To know the name of Alkyne, use IUPAC(International Union of Pure and Applied Chemistry).
According to IUPAC, for the naming of any organic compound containing a triple bond, find the longest chain that contains triple bond & number the chain from the side where triple bond gets lowest number.
in the above diagram, the parent chain cobtains seven carbon atoms with a propyl substituent at 3rd carbon atom. during naming of the compound mention the substituent first along with the position of carbon where is it. Now 7 carbon Atom have prefix (-hept) and Alkyne group is on the first position hence the parent chain would be (hept-1-yne) and substituent (3-propyl).
hence the name of compound is 3-propyl-hept-1-yne

Our earth is situated in the Milky Way galaxy. The Milky Way galaxy is a spiral galaxy. Therefore, the correct option is option C.
What is milky way galaxy?The Milky Way constellation is indeed a huge spiral formation containing hundreds of trillions of stars, along with the Sun. the irregularly formed belt of stars and gas clouds visible from Earth that spans the sky. despite the reality that Earth is positioned within the Milky Way constellation, astronomers do not completely understand its nature, despite its proximity with other external star systems.
A dense layer of interstellar dust obscures the majority of the Galaxy from optical observatories, and astronomers can only understand its massive building with the assistance of radio and infrared telescopes, which can detect the forms of light that may travel through the obscuring material. Our earth is situated in the Milky Way galaxy. The Milky Way galaxy is a spiral galaxy.

The enthalpy tell us about the heat that may be absorbed or evolved in a reaction. The ethalpy of this reaction is -100 kJ/mol.
What is enthalpy?The term enthalpy deals with the heat that is absorbed or emitted in a reaction. The reaction equation is; HNO3 + KOH ----> KNO3 + H2O
Number of moles of HNO3 = 0.5 M * 50/1000 L = 0.025 moles
Number of moles of KOH= 0.5 M * 50/1000 L = 0.025 moles
Since the reaction is 1:1, then heat evolved = - (2500 J * 10^-3)/0.025 moles
= -100 kJ/mol

A manufacturer advertises that a particular brand of lotion is “pH balanced” and that it has a pH equal to 6.25. What can you infer about the lotion based on the information in the ad?
Answers
We can infer about the given information of lotion is that pH is slightly acidic in nature.
What is pH?pH of any solution gives idea about the acidity or basicity of that solution, and it will be calculated as:
pH = -log[H⁺]
pH value in the range of 0 to 6.9 shows acidity, 7 shows the neutral nature and from 7.1 to 14 shows basicity. Given pH value of lotion i.e. 6.25 states that lotion is slightly acidic in nature.
Hence pH value of lotion informs that lotion is slightly acidic.

A balanced chemical equation obeys the law of conservation of mass. The reaction of HCl with Ca(OH)₂ is a weak base - strong acid reaction. The products formed are CaCl₂ and H₂O. The correct option is D.
What is a balanced chemical equation?A chemical equation in which the number of reactants and products on both sides of the equation are equal is defined as the balanced chemical equation. The coefficients are the numbers which are added to balance the chemical equation.
The balanced equation for the reaction of HCl with Ca(OH)₂ is given as:
Ca (OH)₂ (s) + 2HCl (aq) → CaCl₂ (aq) + 2H₂O (l)
Here one mole of Ca (OH)₂ reacts with two moles of HCl and gives one mole of CaCl₂ and two moles of H₂O respectively. Here Ca (OH)₂ is a white precipitate and HCl is a aqueous solution.
Thus the correct option is D.

3.Calculate the pH of a 0.250 M solution of potassium phenolate, KC6H5O. Ka for phenol (C6H5OH) is 1.0 x 10-10.
Answers
From the statement and the information available in the question, the pH of the solution is 12.2.
What is Ka?The term Ka refers to the acid dissociation constant of a substance, we can obtain this by setting up the ICE table as shown;
C6H5O^- + H2O ⇄ C6H5OH + OH^-
I 0.250 0 0
C -X +X +X
E 0.250 -x x x
Now;
Kb = 1 * 10^-14/ 1.0 x 10-10
Kb = 1 * 10^-4
Kb = [C6H5OH] [OH^-]/[C6H5O^-]
1 * 10^-4 = x^2/ 0.250 -x
1 * 10^-4 (0.250 -x) = x^2
2.5 * 10^-4 - 1 * 10^-4 x = x^2
x^2 + 1 * 10^-4 x - 2.5 * 10^-4 = 0
x=0.016 M
Given that; [C6H5OH] = [OH^-] =x
pOH = -log(0.016 M) = 1.8
pH = 14 - 1.8 = 12.2

A. 0.0359 g
B. 0.255 g
C. 17.0 g
D.1134 g
Answers
Answer:
B
Explanation:
From the given chemical equation, we want to determine the mass of arsenic necessary to produce 15.0 mL of 0.0852 M H₂AsO₄⁻.
Find the amount of moles present in 15.0 mL of 0.0852 M H₂AsO₄⁻ solution. Recall that M = mol/L:
[tex]\displaystyle 15.0\text{ mL} \cdot \frac{0.0852\text{ mol H$_2$AsO$_4^-$}}{1\text{ L}} \cdot \frac{1\text{ L}}{1000\text{ mL}} = 0.00128\text{ mol H$_2$AsO$_4^-$}[/tex]
With stoichiometric ratios and molecular weights, determine the mass of arsenic necessary:
[tex]\displaystyle 0.00128 \text{ mol H$_2$AsO$_4^-$} \cdot \frac{8\text{ mol As}}{3\text{ mol H$_2$AsO$_4^-$}}\cdot \frac{74.92\text{ g As}}{1\text{ mol As}} = 0.256\text{ g As}[/tex]
In conclusion, the answer is B.
How many grams of a gas with a molar mass 36.02 g/mol would be required to occupy a 3979 mL flask at 1.07 atm and 81.7 degrees Celcius? Record your answer in scientific notation to 2 decimal spaces.
Answers
A 3979 mL flask is occupied by 5.26 g of a gas with a molar mass of 36.02 g/mol at 1.07 atm and 81.7 °C.
What is an ideal gas?An ideal gas is that whose behavior can be explained using the ideal gas laws.
Step 1. Convert 81.7 °C to Kelvin.We will use the following expression.
K = °C + 273.15 = 81.7 + 273.15 = 354.9 K
Step 2. Calculate the moles of the gas.We will use the ideal gas equation.
P × V = n × R × T
n = P × V / R × T
n = 1.07 atm × 3.979 L / (0.08206 atm.L/mol.K) × 354.9 K = 0.146 mol
Step 3. Calculate the mass of the gas.The molar mass of the gas is 36.02 g/mol.
0.146 mol × 36.02 g/mol = 5.26 g
A 3979 mL flask is occupied by 5.26 g of a gas with a molar mass of 36.02 g/mol at 1.07 atm and 81.7 °C.
