how is substitution reaction in alkanes different from dehydrogenation reaction since both involve removing a hydrogen atom from the molecule?
Answer:
See Explanation
Explanation:
A substitution reaction means the replacement of one or more hydrogen atoms in an alkane by another atom or group. It does not introduce a double bond into the product. The product retains single bonds between the species present.
For instance;
CH4 + Cl2 -------> CH3Cl +HCl
is a substitution reaction
Dehydrogenation is the process of removing two hydrogen atoms from a saturated compound compound thereby yielding an unsaturated product.
E.g
C2H6 --------->C2H4 + H2
The key difference is that substitution reaction yields a saturated product while dehydrogenation yields an unsaturated product.

Given that the nucleophilic substitution reaction used 5.0 mL of t-pentyl alcohol and 12.0 mL of conc. hydrochloric acid to produce t-pentyl chloride, what is the theoretical yield of t-pentyl chloride, in grams
Answer:
4.90 g
Explanation:
Given that:
volume of t-pentyl alcohol = 5 mL
the standard density of t-pentyl alcohol = 0.805 g/mL
Recall that:
density = mass(in wt) /volume
mass = density × volume
mass = 0.805 g/mL × 5 mL
mass = 4.03 g
Volume of HCl used = 12 mL
The reaction for this equation is shown in the image attached below.
From the reaction,
88.15 g of t-pentyl alcohol reacts with concentrated HCl to yield 106.59 g pf t-pentyl chloride.
4.03 g of t-pentyl alcohol forms,
[tex]= \dfrac{106.59 \ g \times 4.03 \ g}{88.15 \ g}[/tex] of t-pentyl chloride.
Therefore,
Theoretical yield of t-pentyl chloride = 4.90 g

The formula for the pH of a solution of hydronium ions is given by the logarithmic equation pH= -log[h3o^+], where [H3o^+] is the hydronium ion concentration. Find the pH of a certain agricultural product with the hydronium ion concentration of 4.7x10^-4
The pH is =?
Answer:
pH = 3.3
Explanation:
Step 1: Given data
Concentration of hydronium ions in the agricultural product ([H₃O⁺]): 4.7 × 10⁻⁴ M
Step 2: Calculate the pH of the agricultural product
We will use the definition of pH.
pH = -log [H₃O⁺]
pH = -log 4.7 × 10⁻⁴
pH = 3.3
Since the pH < 7, the agricultural product is acidic.

PLS HELPP!!!!! A type of waves that carries energy from one place to another, even through empty space is:
A. Amplitude
B. Wave
C. Light
D. Energy
Answer: The answer is C light pretty obvious.
Explanation:
A type of waves that carries energy from one place to another, even through empty space is Light. therefore, option C is correct.
Which kind of waves carry energy from one place to another?Waves can move energy between locations, they do not always move mass. Common examples of waves are light, sound, and ocean waves. Since sound and water waves are mechanical waves, they must move via a medium.
Waves that can pass across the vacuum of space are electromagnetic waves. Unlike electromagnetic waves, mechanical waves must travel through a material medium in order to transfer energy from one place to another.
Electromagnetic waves that are light waves, can move energy both through matter and through space.
Thus, A type of waves that carries energy from one place to another, even through empty space is Light, option C is correct.

Fish breathe the dissolved air in water through their gills. Assuming the partial pressures of oxygen and nitrogen in air to be 0.20 atm and 0.80 atm, respectively, calculate the mole fractions of oxygen and nitrogen in water at 298 K. Comment on your results
Answer:
X(O₂) = 0.323
X(N₂) = 0.677
Explanation:
We have the partial pressures of oxygen (O₂) and nitrogen (N₂):
P(O₂) = 0.20 atm
P(N₂) = 0.80 atm
In order to solve the problem, you need the solubilities of each gas in water at 298 K. We can consider 1.3 x 10⁻³ mol/(L atm) for oxygen (O₂) and 6.8 x 10⁻⁴mol/(L atm) for nitrogen (N₂) from the bibliography.
s(O₂) = 1.3 x 10⁻³ mol/(L atm)
s(N₂) = 6.8 x 10⁻⁴mol/(L atm)
So, we calculate the concentration (C) of each gas as the product of its partial pressure (P) and the solubility (s):
C(O₂) = P(O₂) x s(O₂) = 0.20 atm x 1.3 x 10⁻³ mol/(L atm) = 2.6 x 10⁻⁴mol/L
C(N₂) = P(N₂) x s(N₂) = 0.80 atm x 6.8 x 10⁻⁴mol/(L atm) = 5.44 x 10⁻⁴ mol/L
In 1 liter of water, we have the following number of moles (n):
n(O₂) = 2.6 x 10⁻⁴ mol
n(N₂) = 5.44 x 10⁻⁴ mol
Thus, the total number of moles (nt) is calculated as the sum of the number of moles of the gases in the mixture:
nt = n(O₂) + n(N₂) = 2.6 x 10⁻⁴ mol + 5.44 x 10⁻⁴ mol = 8.04 x 10⁻⁴ mol
Finally, the mole fraction of each gas is calculated as the ratio between the number of moles of each gas and the total number of moles:
X(O₂) = n(O₂)/nt = 2.6 x 10⁻⁴ mol/(8.04 x 10⁻⁴ mol) = 0.323
X(N₂) = n(N₂)/nt = 5.44 x 10⁻⁴ mol/(8.04 x 10⁻⁴ mol) = 0.677

how many moles of lithium are in 18.2 grams of lithium
Answer:
I think 2.6 sorry if its wrong
The number of moles of 18.3 grams of lithium is equal to 2.62 mol.
What is a mole?A mole can be defined as a metric unit that is used to evaluate a count of particles in the sample of a given substance. The particles counted are generally identical chemical entities, but they are individually distinct.
A mole is used for a large number of quantities of molecules, atoms, ions, or other specific particles. The number of chemical compounds or elements can be measured in the terms of moles.
The number of units of the chemical which are present in 1 mole is equal to 6.023 × 10 ²³ refers to Avogadro’s constant.
Given, the mass of lithium in the sample = 18.2 g
The mass of one mole of lithium = 6.94 g
6.94 grams of lithium has moles = 1 mol
18.2 g of lithium has moles of Li = 18.2/6.94 = 2.62 mol
Therefore, the moles in 18.2 g of Lithium is 2.62 mol.
