259 mL of gas is collected at 112 kPa of pressure. What will be the volume at standard pressure, assuming the temperature remains constant? Remember, STP is standard temperature (273 K) and standard pressure (1 atm). Round your answer to 3 significant figures.

Love you so much if you can answer x​

Answers

Answer 1

The volume at standard pressure will be 293 mL.

To find the volume of gas at standard pressure, we need to use the ideal gas law, which states that PV = nRT, where P is pressure, V is volume, n is the number of moles, R is the gas constant, and T is the temperature.

Since the temperature remains constant, we can rearrange the equation to solve for the volume at standard pressure:

(P₁V₁) / P₂ = V₂

Where P₁ is the initial pressure, V₁ is the initial volume, P₂ is the final pressure (standard pressure), and V₂ is the final volume (what we're solving for).

Plugging in the given values, we get:

(112 kPa)(259 mL) / (1 atm) = V₂

Simplifying and converting units of pressure and volume, we get:

(112000 Pa)(0.259 L) / (1.01325 × 10⁵ Pa) = V₂

Solving for V₂, we get:

V₂ = 0.293 L = 293 mL

Rounding to 3 significant figures, we get that the volume at standard pressure will be 293 mL.

select the compound(s) can undergo an aldol addition reaction in the presence of aqueous sodium hydroxide? question 18 options: 2,2-bromopentanal pentanal 2-methyl pentanal 3-chloropentanal

Answers

Option 1 is correct compound. 2-bromopentanal and pentanal do not have alpha-hydrogens and therefore cannot undergo aldol addition reaction in aqueous sodium hydroxide.

Out of the given options, only 2-methyl pentanal and 3-chloropentanal can undergo aldol addition reaction in the presence of aqueous sodium hydroxide. This is because both of these compounds have alpha-hydrogens (hydrogens attached to the carbon adjacent to the carbonyl group), which are necessary for the aldol reaction to occur.

Aldol condensations play an important role in the creation of organic compounds because they provide a dependable way to create carbon-carbon bonds. For instance, the Robinson annulation reaction sequence results in aldol condensation, and the Wieland-Miescher ketone product is an essential component in a variety of chemical synthesis processes.

if 6 moles of a a compound produce 84 J of energy, what is the h reaction in j/mol

Answers

The enthalpy of the reaction is 14 J/mol.

The enthalpy of a reaction (ΔH) is the amount of energy transferred between a system and its surroundings during a chemical reaction at constant pressure, measured in joules per mole (J/mol). This value is important because it can tell us whether a reaction is exothermic or endothermic, as well as give us information about the strength of chemical bonds within the reactants and products.To calculate the enthalpy of a reaction, we need to know the amount of energy released or absorbed (Q) and the number of moles of the compound involved in the reaction (n). We can use the equation:
ΔH = Q/n
Given that 6 moles of a compound produce 84 J of energy, we can calculate the enthalpy of the reaction as follows:
ΔH = Q/n
ΔH = 84 J / 6 mol
ΔH = 14 J/mol
This means that for every mole of the compound involved in the reaction, 14 J of energy is transferred between the system and the surroundings. Since the value is positive, we can conclude that the reaction is endothermic, meaning that it requires an input of energy to occur.It is worth noting that the enthalpy of a reaction can depend on a number of factors, such as temperature, pressure, and the specific conditions under which the reaction occurs. As such, it is important to take these factors into account when calculating or predicting enthalpy values.

at 40 degrees celsius, calculate the ph of a solution made by mixing equal volumes of squeous solutions of 1.0m hcl and 1.2m naoh. assume volumes are additive

Answers

The pH of the solution made by mixing equal volumes of 1.0M HCl and 1.2M NaOH at 40 degrees Celsius is 7.

To calculate the pH of the solution, we first need to find the concentration of the resulting solution after mixing HCl and NaOH. Since equal volumes of 1.0M HCl and 1.2M NaOH are mixed, we can assume that the final volume of the solution is equal to the sum of the volumes of the two solutions, which is 2.0 L.

The reaction between HCl and NaOH is a neutralization reaction, which produces water and a salt (NaCl). The balanced equation is:

HCl + NaOH → NaCl + H2O

Since equal volumes of HCl and NaOH are mixed, they will completely react with each other, and no excess H+ or OH- ions will be left in the solution. Thus, the resulting solution will be neutral, with a pH of 7.

Therefore, the pH of the solution made by mixing equal volumes of 1.0M HCl and 1.2M NaOH at 40 degrees Celsius is 7.

A clinical trial was conducted to test the effectiveness of a drug for treating insomnia in older subjects. Before treatment, 21 subjects had a mean wake time of 105.0 min. After treatment, the 21 subjects had a mean wake time of 83.1 min and a standard deviation of 20.7 min. Assume that the 21 sample values appear to be from a normally distributed population and construct a 95% confidence interval estimate of the mean wake time for a population with drug treatments. What does the result suggest about the mean wake time of 105.0 min before the treatment? Does the drug appear to be effective? Construct the 95% confidence interval estimate of the mean wake time for a population with the treatment. min<μ

Answers

The 95% confidence interval estimate for the mean wake time with the drug treatment is between 76.6 min and 89.6 min.

The 95% confidence interval estimate is calculated based on the sample mean and the standard deviation. In this case, the sample mean wake time after treatment is 83.1 min, and the standard deviation is 20.7 min. With these values, we can construct the confidence interval estimate.

The formula for calculating the confidence interval estimate is:

CI = sample mean ± (critical value * standard deviation / square root of sample size)

Using a 95% confidence level, the critical value is 1.96. The sample size in this case is 21.

Plugging in the values:

CI = 83.1 ± (1.96 * 20.7 / √21)

Simplifying the equation:

CI = 83.1 ± 8.08

Therefore, the 95% confidence interval estimate for the mean wake time with the drug treatment is between 76.6 min (83.1 - 8.08) and 89.6 min (83.1 + 8.08).

This result suggests that the mean wake time before the treatment, which was 105.0 min, is outside the confidence interval estimate. The confidence interval estimate does not include the value of 105.0 min, indicating that the mean wake time with the drug treatment is significantly different from the mean wake time before the treatment.

How do amphetamines work? (select all that apply)
A. bind to and block dopamine transporters; allow dopamine to remain in the synaptic cleft longer
B. cause the dopamine transporter to run in reverse; increase the dopamine concentration in the synaptic cleft
C. bind to and block serotonin transporters; allow serotonin to remain in the synaptic cleft longer
D. increase norepinephrine concentrations in the synaptic cleft

Answers

Amphetamines work by primarily binding to and blocking dopamine and norepinephrine transporters, thereby increasing the concentration of these neurotransmitters in the synaptic cleft. They can also have effects on serotonin transporters, but to a lesser extent. This prolonged presence of dopamine and norepinephrine in the synaptic cleft leads to increased neurotransmission and stimulation of the central nervous system.

Amphetamines, such as Adderall or methamphetamine, exert their effects by targeting neurotransmitter transporters. The most significant impact is on dopamine transporters (option A). Amphetamines bind to dopamine transporters and block their activity, preventing the reuptake of dopamine into presynaptic neurons. As a result, dopamine remains in the synaptic cleft for a longer time, increasing its concentration and enhancing dopamine signaling.

In addition to affecting dopamine, amphetamines also influence norepinephrine (noradrenaline) levels in the synaptic cleft (option D). They bind to norepinephrine transporters and inhibit their function, leading to increased norepinephrine concentration in the synapse.

While amphetamines can have some impact on serotonin transporters (option C), their effects on serotonin are relatively weaker compared to dopamine and norepinephrine. The precise mechanism of how amphetamines affect serotonin transporters is still not fully understood.

Overall, the primary mechanism of action of amphetamines involves increased dopamine and norepinephrine concentrations in the synaptic cleft, resulting in enhanced neurotransmission and stimulation of the central nervous system.

The tiny, compact area of protons and neutrons at the heart of an atom is known as the atomic nucleus. The strongest known basic force, often known as the strong force, is what holds these things together. Despite making up far less than.01 percent of the atom's volume, the nucleus normally takes up more than 99.9% of its mass.

Within a few minutes after the Big Bang, nucleosynthesis started. Protons and neutrons were then formed from a quark-gluon plasma, a concentrated soup of quarks and gluons. The neutron-proton merger produced the deuterium isotope's nuclei after the cosmos somewhat cooled. Protons and neutrons make up every atomic nucleus, and the quantity of protons determines the size of the nucleus.Each chemical element has different isotopes, which are determined by the chemical element and the neutron count.
