The graph below shows how the pH of the soil in
a farmer's field changed over a period of time.
At which point, A, B, C or D, did the farmer apply
lime to the field?
Answers
Answer:
Point B
Explanation:
From 0 - 7 on the pH scale, substances are said to be acidic. At 7, the substance is said to be neutral. From 7 - 14, substances are basic.
Lime is a basic substance. Therefore, when it is added to the soil, one should expect that the soil becomes more basic. On the graph, this should be represented by the line increasing in pH. As such, the point at which lime was added was most likely Point B.

In the combustion of propane: __ C3H8 __ O2 --> __ CO2 __ H2O When the equation is balanced using the smallest whole numbers, the coefficient of O2 will be:
Answers
Answer:
1 C3H8 + 5 O2 --> 3 CO2 + 4 H2O
Explanation:
USE PENCIL! Balancing equations typically requires some initial trial and error. Making changes is common.
_ C3H8 __ O2 --> __ CO2 __ H2O
We know we can only have whole molecules, so all number coefficients must be, eventually, whole numbers. It is OK to start with a fraction, but the final must be a shole number. Pick the most complex molecule (either product or reactant) and assign it a coefficient of 1.
1 C3H8 __ O2 --> __ CO2 __ H2O
Now find places for each of the atoms in C3H8 on the product side. 3 carbons means we need 3CO2 molecules, so add a coeffient of 3,
1 C3H8 __ O2 --> 3 CO2 __ H2O
3 CO2 means we need 6 oxygens, so add a coefficient of 3 for the O2:
1 C3H8 + 3 O2 --> 3 CO2 __ H2O
Now find a home for the 8 hydrogens that come from the 1 C3H8. Add 4 to the H2O product:
1 C3H8 + 3 O2 --> 3 CO2 + 4 H2O
This last step added 4 more O to the product side, so we need to adjust the reactant source of O:
1 C3H8 + 5 O2 --> 3 CO2 + 4 H2O
Double check the result:
Element Reactant Product
C 3 3
H 8 8
O 10 10(6+4)
Everything checks.
[Note that one might use a fraction such as 1/2 or 1/3 just to make the balance work. But fractions must be converted to whole numbers for the final equation. For 1/2, multiply all coefficients by 2. By 3 for 1/3, etc.]

What do you mean by Isotopes?Isotopes are two or more atom types that share the same atomic number (number of protons in their nuclei), location in the periodic table, and chemical element but have distinct nucleon numbers (mass numbers) as a result of having a different number of neutrons in their nuclei. Although the chemical properties of each isotope of a given element are nearly identical, they differ in their atomic weights and physical characteristics.
191.86 =(62% x 194.96 + 38% x X )
where, X is the mass of other Isotope.
X = (191.86 - 120.8752)/0 .38
= 186.80

In calorimetry, what physical quantity do we measure to qualitatively assess if a reaction is endothermic or exothermic?.
Answers
The physical quantity used to qualitatively assess if a reaction is endothermic or exothermic in calorimetry is heat.

Assessment of the reaction:The heat generated by an exothermic reaction in solution is trapped in the calorimeter when we perform the process, raising the temperature of the solution. Running an endothermic reaction causes the solution's temperature to drop as the reaction's heat source is removed from the solution.Characteristics of endothermic reaction:Any chemical process that takes heat from its surroundings is said to be endothermic. The reaction's activation energy comes from the energy that was absorbed. This kind of reaction is characterized by its cold sensation.Characteristics of exothermic reaction:Exothermic simply means releasing heat. As an exothermic process develops, energy, frequently in the form of heat, is released.In an exothermic reaction, it takes less energy to break bonds in the reactants than is released when new bonds form in the products.To learn more about endothermic and exothermic reactions visit:

A mixture of methane (CH₄) and butane (C₄H₁₀) at one atmosphere pressure and 25°C has a density of 1.375 g/L. Assuming ideal behavior, what is the mass in grams of carbon that are in 1 liter of the mixture?
Answers
The mass of carbon in 1 liter of mixture = 1.108 g
What is the mass of carbon in 1 liter of the mixture?The mass of carbon in 1 liter of the mixture is determined as follows:
First the moles of gas is determined using the ideal gas formula:
n = PV/RTn = (1 * 1)/(0.08205L * 298)
n = 0.0409 mole of total gas
mass of gas is then determined using the formula:
mass = density * volumemass = 1 * 1.375
mass = 1.375 g
Let x = mass of CH₄ and y = mass of C₄H₁₀
x + y = 1.375 g
nCH₄ + nC₄H₁₀ = ntotat
moles = mass/molar mass
x + y = 1.695 => y = 1.695 - x
(x/molar mass of CH₄) + [(1.375 - x)/ molar mass C₄H₁₀ = 0.0409
x/16 + (1.375 - x)/58 = 0.0409
x = 0.380 g CH₄
y = 1.375 - 0.380
y = 0.995 g of C₄H₁₀
mass of C in CH₄ = 12/16 * 0.380 = 0.285
mass of C in C₄H₁₀ = 48/58 * 0.995 = 0.823
Mass of carbon in 1 liter of mixture = 0.285 + 0.823
Mass of carbon in 1 liter of mixture = 1.108 g
In conclusion, the carbon is the major component in the mixture.

C3H8 has a boiling point than C2H6
Answers
Answer:
C₃H₈ has a higher boiling point than C₂H₆
Explanation:
The boiling point is the temperature at which the intermolecular bonds holding molecules in liquid form are overcome and change the state into a gas. C₃H₈ experiences stronger intermolecular bonds then C₂H₆ because it has more carbons. While the strength of each bond is the same between the two molecules, C₃H₈ has more opportunities to create these bonds due to the higher carbon count. The more bountiful the intermolecular bonds, the more energy is needed to overcome them all. Thus, C₃H₈ has a higher boiling point.

Answers
The enthalpy of fusion for Hg is 2.29 kJ/mol. 0.89 kJ is the energy change when 78.0 g of Hg melts at −38.8°C.
What is Enthalpy of Fusion ?The amount of energy needed to change 1 mole of substance under state change at constant temperature and pressure is called enthalpy of fusion. It is also known as Latent heat of fusion. Unit of enthalpy of fusion is kJ/mol.
How to find the change in energy ?To find the change in energy use this expression:
q = n ΔH
where
q = Energy change
n = number of moles
ΔH = Molar enthalpy
Number of moles (n) = [tex]\frac{\text{Given mass}}{\text{Molar mass}}[/tex]
= [tex]\frac{78.0\ g}{200\ \text{g/mol}}[/tex]
= 0.39 mol
Now put the values in above formula we get
q = n ΔH
= 0.39 mol × 2.29 kJ/mol
= 0.89 kJ

A helium balloon has a volume of 2600 cm 3 when the temperature is 21°C. What is the

Answers
Answer:
2,282 cm³
Explanation:
If all other variables are being held constant, you can find the new volume of the balloon using the Charles' Law equation. The equation looks like this:
V₁ / T₁ = V₂ / T₂
In this equation, "V₁" and "T₁" represent the initial volume and temperature. "V₂" and "T₂" represent the final volume and temperature. Before you can solve for the new volume, you need to convert Celsius to Kelvin (negative values do not work in this equation). This can be done by adding 273.15 to each temperature.
V₁ = 2600 cm³ V₂ = ? cm³
T₁ = 21 °C + 273.15 = 294.15 K T₂ = -15 °C + 273.15 = 258.15 K
V₁ / T₁ = V₂ / T₂ <----- Charles' Law
(2600 cm³) / (294.15 K) = V₂ / (258.15 K) <----- Insert values
8.839 = V₂ / (258.15 K) <----- Simplify left side
2282 = V₂ <----- Multiply both sides by 258.15
