In a Base catalyst elimination, the base extracts a proton and the leaving group leaves simultaneously. In a Concentrated process, the leaving group leaves the base abstracts a proton.
Just as there are two mechanisms of substitution (SN2 and S N1), there are two
mechanisms of elimination (E2 and E1).
E2 mechanism — bimolecular elimination
E1 mechanism — unimolecular elimination
The E2 and E1 mechanisms differ in the timing of bond cleavage and bond formation, analogous to the SN2 and S N1 mechanisms.
E2 and S N2 reactions have some features in common, as do E1 and SN1 reactions.
Base removes a proton from the β-carbon atom,
while the halogen atom leaves from the α-carbon resulting in the formation of a π-bond. Such eliminations are also called β-eliminatione liminations are also called β elimination reactions
In a base-catalyzed elimination reaction, the base takes away a proton from the β position of the leaving group (the group that goes away with the bonding pair of electrons) and a double bond is formed. When the base is bulky it prefers to take away the proton from the less hindered position.

g A solution is made by dissolving 0.0550 moles of Ba(OH)2 in enough water to make 325 mL of solution. What is the pH of the resulting solution
The pH of this solution is 13.529.
Given:
Number of moles Ba(OH)₂ = 0.0550 moles
Volume = 325 mL
The calculation for moles:
[tex]Ba (OH)_{2}[/tex] → [tex]Ba^{2}[/tex]⁺ + [tex]2OH[/tex]
In 1 moles Ba(OH)₂ we have 2 moles OH-
In 0.0550 moles Ba(OH)₂ we have 2*0.0550 = 0.11 moles OH-
The calculation for concentration:
[OH-] = moles / volume
[OH-] = 0.11 moles / 0.325 L
[OH-] = 0.338 M
Calculation of pOH:
pOH = -log[OH-]
pOH = -log(0.338)
pOH = 0.471
Calculation of pH:
pH + pOH = 14
pH = 14 - pOH
pH = 14 - 0.471
pH = 13.529
Thus, the pH of this solution is 13.529.

Which factor does not increase the rate of a reaction? decreasing the concentration of the reactants increasing the temperature of the system increasing the surface area of the reactants adding an effective catalyst to the system
Rate of Reaction:
The factor that does not increase the rate of a reaction is "decreasing the concentration of the reactants".
Factors that increase the rate of a reaction:
Increasing the temperature of the system: The average kinetic energy of the reactant molecules will rise as the temperature rises. As a result, a higher percentage of molecules will possess the minimal amount of energy required for an efficient collision, increasing the rate of reactions.Increasing the surface area of the reactants: More particles are exposed to the other reactant when the surface area of a reactant is increased. Particles collide more frequently, increasing the number of successful collisions per second. Thus increasing the rate of reaction.Adding an effective catalyst to the system: A catalyst is a substance that participates in a reaction without being absorbed, speeding up the process.

The original temperature of the copper is 145.4 °C
What is temperature?Temperature refers to the degree of hotness or coldness of a body. Now we know that the heat lost by the copper is equal to the heat gained by the water. The heat lost is negative while the heat gained is positive.
Hence;

What mass of carbon dioxide is produced upon the complete combustion of 17.0 LL of propane (the approximate contents of one 5-gallon tank)
The mass of carbon dioxide that is produced will be 31,671 grams or 31.671 kg
Stoichiometric calculationsFirst, the equation of the reaction:
[tex]C_3H_8(g)+5O_2(g)-- > 3CO_2(g)+4H_2O(g)[/tex]
The mole ratio of propane burned to carbon dioxide produced is 1:3.
The density of propane gas is 0.621 g/mL, thus, 17.0 L of propane will weigh:
Density = mass/volume, mass = 0.621 g/mL x 17000 = 10,557 g
Mole of 10,557 g of propane = 10557/44.1 = 239.39 moles
Equivalent mole of carbon dioxide produced = 239.39 x 3 = 718.16 moles
Mass of 718.16 moles carbon dioxide = 718.16 x 44.1 = 31,671 grams or 31.671 kg

4. A weather balloon containing 35.0 L of helium at 98.0 kPa is released and rises.
Assuming that the temperature is constant, fine the volume of the balloon when the
atmospheric pressure is 25.0 kPa at a height of about 25 km.
Answer:
137.2 L
Explanation:
p1v1 = p2v2
p1v1 / p2 = v2
98 * 35 / 25 = v2 = 137.2 L
To find the volume of the balloon when the atmospheric pressure is 25.0 kPa at a height of about 25 km, we can use Boyle's Law,as per which volume is 137.2 L.
Boyle's law is an experimental gas law which describes how the pressure of the gas decreases as the volume increases. It's statement can be stated as, the absolute pressure which is exerted by a given mass of an ideal gas is inversely proportional to its volume provided temperature and amount of gas remains unchanged.
Boyle's Law equation: P₁ V₁ = P₂ V₂
Given:
P₁= 98.0 kPa (initial pressure of the balloon)
V₁ = 35.0 L (initial volume of the balloon)
P₂ = 25.0 kPa (final atmospheric pressure)
V₂= unknown (final volume of the balloon)
Plugging in the values into Boyle's Law equation, we have:
98.0 kPa × 35.0 L = 25.0 kPa × V₂
To find V₂, we can rearrange the equation:
V₂ = [tex]\dfrac{98}{35}\times{25}\\=137.2 \ L.[/tex]
Therefore, the volume of the balloon when the atmospheric pressure is 25.0 kPa at a height of about 25 km is approximately 137.2 L.

What is buffer solution?A buffer solution, also known as a buffer, is a mixture of a weak acid and its conjugate base (or a mixture of a weak base and its conjugate acid). When a weak acid or a weak base is applied in modest amounts, buffer solutions withstand the pH shift.

A synthesis reaction takes place when carbon monoxide (CO) and hydrogen gas (H2) react to form methanol (CH3OH). How many grams of methanol are produced when 14 grams of carbon monoxide reacts with 1.5 grams of hydrogen gas
12 g CH3OH are produced when 14 grams of carbon monoxide reacts with 1.5 grams of hydrogen gas.
Writing the balanced equation for the reaction taking place:
CO(g) + 2H2(g) ⇒ CH3OH
Finding the limiting reactant:
moles CO present ⇒ 14 g x 1 mol CO / 28 g = 0.5 moles CO
moles H2 present ⇒ 1.5 g x 2 mol H2 / 2 g = 0.75 moles H2O
Because according to the balanced equation it takes 2 moles of H2 for every 1 mole CO, there isn't enough H2, so it is limiting and will dictate how much CH3OH can be made.
Mass of CH3OH produced
= 0.75 moles H2 x 1 mol CH3OH / 2 mol H2 x 32 g CH3OH / mol
= 12 g CH3OH
