Question 3 of 5
Which two characteristics describe the pair of objects experiencing greater
gravitational force?
2 kg
2 kg
S kg
5 kg
d = 1 m
d = 5 m
D A. More mass
B. Greater distance between them
C. Shorter distance between them
I D. Less mass
SUS
Answer:
A. More mass
C. Shorter distance between them
Explanation:
The two characteristics of a body experiencing greater gravitational force are that they have mass and a shorter distance between them.
This is conformity with Newton's law of universal gravitation.
The law states that "every object attracts one another with a force that is directly proportional to their masses and inversely proportional to the square of the distance between them".
This law implies that the more the mass of two bodies, the more the gravitational force of attraction. And that the shorter the square of the distance between them, the more the attraction.
Answer:
A. More Mass And
C. Shorter Distance Between Them

Calculate the volume of the gas, in liters, if 1.35 mol
has a pressure of 1.30 atm
at a temperature of -6 ∘C?
Answer:
22.8 L
Explanation:
Step 1: Given data
Moles of the gas (n): 1.35 molPressure of the gas (P): 1.30 atmTemperature (T): -6°CIdeal gas constant (R): 0.0821 atm.L/mol.KStep 2: Convert "T" to Kelvin
We will use the following expression.
K = °C + 273.15 = -6 + 273.15 = 267 K
Step 3: Calculate the volume of the gas
We will use the ideal gas equation.
P × V = n × R × T
V = n × R × T / P
V = 1.35 mol × (0.0821 atm.L/mol.K) × 267 K / 1.30 atm
V = 22.8 L

How many grams are in 0.55 moles of C6H10S?
Answer:
62.7 gram
Explanation:
Molar mass = (6)(12)+(10)(1)+(1)(32)=114 g/mol
Mass = no of moles × molar mass
= 0.55 × 114 = 62.7 gram
The mass of 0.55 moles of compound C₆H₁₀S is equal to 62.7 g.
What is a mole?A mole is defined as a standard unit that is used to find a huge number of quantities such as atoms, molecules, ions, or other particles. The mass of the 1 mole of any chemical element is equal to the atomic mass of the element and that of any chemical compound is known as molar mass.
The number of entities in 1 mole was found to be equal to 6.023 × 10²³ which is known as Avogadro’s number or Avogadro's constant
Given, the number of moles of the given compound = 0.55 moles
The mass of 1 mole of given compound C₆H₁₀S = 114 g/mol
The mass of 0.350 moles of the given compound = 0.55 × 114 = 62.7 g
Therefore, 62.7 grams is the mass of 0.55 moles of C₆H₁₀S.

The mass of a block is 12 g and the volume is 6 ml. Calculate the density of the block.
Question 2 options:
18 g/ml
72 g/ml
0.5 g/ml
2 g/ml
Answer:
According to mass and volume, block density is 2 g/ml
Explanation:
Density is a measure, usually used in physics and chemistry, that relates the mass and volume of a solid or compound.
In general terms, the density is directly proportional to the mass, and inversely proportional to the volume, so increasing the mass will also increase the density.
The formula used to calculate the density is
ρ = [tex]\frac{m}{V}[/tex]
Therefore, according to the mass and density of the block
ρ = [tex]\frac{12}{6}[/tex] = 2g/ml
Being the density of the block equal to 2 g/ml.
The other options are not possible, because the values given do not correspond to the result of the equation.

Answer the following questions about the mechanism for the acid-catalyzed hydration of an alkene:
a. How many transition states are there?
b. How many intermediates are there?
c. Which step in the forward direction has the smallest rate constant?
Answer:
a) there are three transition states
b) there are two intermediates; carbocation and protonated alcohol
c) The first step in the forward direction
Explanation:
The acid-catalysed hydration of alkenes proceeds via a carbocation mechanism.
Three transition states can be identified in this mechanism for the acid-catalyzed hydration of alkenes.
The three transition states are derived from the three steps in the reaction sequence:
1) Protonation of the alkene by hydronium ion
2) Addition of water to the carbocation
3) loss of a proton to yield the alcohol
The first step involves the breaking of a pi bond, hence it is a slow step hence it has the smallest rate constant. The other two steps are fast steps.
When 2.499 g of AX (s) dissolves in 135.3 g of water in a coffee-cup calorimeter the temperature rises from 23.6 °C to 35.2 °C. Calculate the enthalpy change (in kJ/mol) for the solution process. AX space (s )space rightwards arrow straight A to the power of plus (a q )space plus space straight X to the power of minus space (a q )Assumptions for this calculation: The specific heat of the solution is the same as that of pure water (4.18 J/gK) The density of water = 1.000 g/mL The liquid’s final volume is not changed by adding the solid The calorimeter loses only a negligible quantity of heat. The formula weight of AX = 59.1097 g/mol. Be sure you include the correct sign for the enthalpy change.
Answer:
The enthalpy change for the solution process [tex]\Delta H_{rxn}[/tex] = - 158.34 kJ/mol
Explanation:
Given that:
The mass of salt AX = 2.499 g
The mass of water = 135.3 g
The mass of the solution = ( 2.499 + 135.3 ) g = 137.799 g
The specific heat of salt solution s is known to be = 4.18 J/g° C
The change in temperature i.e. ΔT = 35.2 °C - 23.6 °C = 11.6 °C
Thus, the amount of heat raised is equal to the heat absorbed by the calorimeter.
∴
[tex]q_{reaction} = q_{solution}[/tex]
[tex]q_{reaction} = -ms_{solution} \Delta T[/tex]
[tex]q_{reaction} = -137.799 \ g \times 4.18 \dfrac{J}{g^0C}\times 11.6^0C[/tex]
[tex]q_{reaction} = - 6682 \ J[/tex]
[tex]q_{reaction} = - 6.682 \ kJ[/tex]
Recall that the mass of the salt = 2.499 g
The number of moles of the salt = [tex]2.499 \ g \times \dfrac{1 \ mol \ of \ AX}{59.1097 \ g}[/tex]
= 0.0422 mol of AX
Finally the enthalpy change, [tex]\Delta H_{rxn} = \dfrac{- 6.682 \ kJ}{ 0.0422 \ mol}[/tex]
= - 158.34 kJ/mol
The enthalpy change for the solution process [tex]\Delta H_{rxn}[/tex] = - 158.34 kJ/mol

How many gallons of concentrated sulfuric acid (density of 1.84 g/cm3) are required to have a mass of 184.33 pounds?
Note: 1 kg = 2.204 lb, 1 gallon = 3.79 L.
After series of conversion from one unit to another, the number of gallons was found to be 12 litres
Density, Mass and Volume
Given Data
Density of Sulfuric acid = 1.84 g/cm3Mass of Sulfuric acid = 184.33 PoundsConversion from pounds to Gram
1 kg ---------2.204 lb
x kg ---------184.33 lb
x = 184.33/2.204
x = 83.634 kg
hence the mass in gram = 83.634*1000
mass in gram = 83634 g
Now let us find the volume
We know that density = mass/volume
volume = mass/density
volume = 83634/1.84
volume = 45453.26 cm^3
Convert cm^3 to litres
Volume in litres = 45453.26 /1000
Volume in litres = 45.45 Litres
Convert from Litres to Gallons
1 gallon = 3.79 L
