equation for the decomposition of water. What happens to the electrons and to the H+ and OH- ions?

Answers

Answer 1

To cancel (doubling the reduction reaction), the electrons must be equal on both sides for the H+ and OH- ions to combine to form water.

How to balance oxidation reduction reaction?

step 1:

Write down the two half equations that describe the oxidation and reduction processes. Step 2:

If necessary, multiply the equations to get the same number of electrons on both sides of the equation. Step 3:

Remove the electrons, combine the equations, and add the remaining species.

A half-reaction is either the oxidation or reduction reaction component of a redox reaction. Half-reactions are obtained by considering the change in oxidation state of the individual substances involved in the redox reaction.

Based on the passage, which amino acid will most likely react with phosphine? cysteine has sulfhydryl groups and can make disulfide bonds. Methionine is the other amino acid that is sulfur containing, but cannot make disulfide bonds.

Answers

Cysteine is the amino acid that will most likely react with phosphine.

Cysteine contains sulfhydryl (-SH) groups that can form disulfide bonds (-S-S-) with other cysteine residues in a protein. This is important for maintaining the proper 3-dimensional structure of the protein.

Phosphine is a highly reactive gas that can react with the sulfhydryl groups of cysteine.

Methionine, on the other hand, is also a sulfur-containing amino acid, but it does not have the ability to form disulfide bonds. This means that it is unlikely to react with phosphine.

how would the 1h nmr spectrum of an alcohol be affected by the addition of d2o to replace the oh protons with d atoms?

Answers

When adding D2O to an alcohol, the hydrogen atoms of the OH groups are replaced by deuterium atoms (D).

This affects the 1H NMR spectrum of the alcohol by shifting the peaks of the OH protons. The chemical shift of the hydroxyl group is shifted from its original position at a chemical shift of ~10-12 ppm to a higher chemical shift of ~4-6 ppm for the deuterium atom. This shift is due to the higher mass of the deuterium atom compared to the hydrogen atom. As a result, the peaks of the OH protons are shifted downfield and are seen more prominently in the 1H NMR spectrum. This can be calculated using the equation:

Chemical shift (δ) = (δD - δH) × (M/m)

where δD is the chemical shift of the deuterium atom, δH is the chemical shift of the hydrogen atom, M is the mass of the deuterium atom (2) and m is the mass of the hydrogen atom (1).

given the balanced equation: 2 lioh co2 li2co3 h2o, how much h2o will be produced if 25.4 g lioh reacts with 64.8 g co2?

Answers

if 25.4 g of LiOH reacts with 64.8 g of CO2, 9.54 g of H2O will be produced.

We can start by using the coefficients in the balanced equation to convert the number of moles of one substance to the number of moles of another substance.

Convert the masses of LiOH and CO2 to moles:

moles of LiOH = 25.4 g / (23.9 g/mol) = 1.06 molmoles of CO2 = 64.8 g / (44.0 g/mol) = 1.47 mol

Determine the limiting reactant:

Since the ratio of the coefficients in the balanced equation is 2:1 for LiOH to CO2, we can see that the limiting reactant is LiOH. This means that we will run out of LiOH before CO2, so we will use the moles of LiOH to calculate the amount of H2O produced.

Calculate the number of moles of H2O produced using the balanced equation:

From the balanced equation, for every 2 moles of LiOH that react, 1 mole of H2O is produced. So, the number of moles of H2O produced is:

1.06 mol LiOH / 2 mol LiOH/mol H2O = 0.53 mol H2O

Convert the number of moles of H2O to mass:

Mass of H2O = 0.53 mol * (18.0 g/mol) = 9.54 g

So, if 25.4 g of LiOH reacts with 64.8 g of CO2, 9.54 g of H2O will be produced.

Answers

In an H NMR spectrum of an ethyl group, the protons of the ethyl group appear as a 2H triplet and a 3H quartet.

The 2H triplet and 3H quartet in NMR spectroscopy are due to the two protons in the methyl group of the ethyl group and the three protons in the ethyl group respectively. The triplet has a higher intensity than the quartet as the three protons in the ethyl group are further apart, resulting in a smaller coupling constant.

Conversely, the quartet has a lower intensity due to the small distance between the two protons in the methyl group, resulting in a larger coupling constant. The 2H triplet can be distinguished from the 3H quartet as the triplet has a single peak, while the quartet has four peaks.

In order to identify which ion (1) enters the cell from outside and (2) causes the increase in voltage, a researcher would want to manipulate a positive ion such as Na+.

Answers

Researchers could change the concentration of Na+ ions in the solution bathing the axon.

The elements that impact the membrane potential in neurons are many. They contain a wide range of ion channels, some of which are chemically gated and others of which are voltage-gated. Because voltage-gated ion channels are regulated by the membrane potential, and the membrane potential is impacted by these ion channels, feedback loops that allow for complex temporal dynamics, such as oscillations and regenerative events like action potentials, emerge.

A cell's membrane potential is ultimately determined by two factors: electrical force and diffusion.

what force will be necessary to slide a rubber puck of mass 0.55 kg on dry concrete? use the appropriate coefficients of friction from the previous lesson. (2 marks)

Answers

The force required to slide the puck is approximately 4.13 N.

The force required to slide a rubber puck on dry concrete is equal to the friction force acting between the puck and the concrete. The coefficient of friction for rubber on concrete is typically around 0.75. To find the frictional force, you can use the equation:

f_friction = friction_coefficient * f_norm

where f_norm is the normal force pressing the puck against the concrete, which is equal to the puck's weight (mass * gravity). Thus,

f_friction = 0.75 * m * g

where m is the mass of the puck (0.55 kg) and g is the acceleration due to gravity (9.8 m/s^2).

Therefore, the force required to slide the puck is approximately 4.13 N. It is important to note that this force is only an estimate, as there are many factors that can influence the frictional force, such as the smoothness of the concrete surface, the temperature, and humidity.

About Atom

The atom is a basic unit of matter, consisting of an atomic nucleus and a cloud of negatively charged electrons that surrounds it. The atomic nucleus consists of positively charged protons and neutrally charged neutrons (except in the atomic nucleus of Hydrogen-1, which has no neutrons).

The electrons in an atom are bound to the nucleus by electromagnetic forces. A collection of such atoms can also bond with each other, and form a molecule. Atoms containing the same number of protons and electrons are neutral, while those containing a different number of protons and electrons are positive or negative and are called ions. Atoms are grouped based on the number of protons and neutrons contained in the atomic nucleus. The number of protons in an atom determines the chemical element of that atom, and the number of neutrons determines the isotope of that element.

how many moles of gas are in a 60.8 l container with a pressure of 2.44 atm at a temperature of 275 k?

Answers

Answer: 24.7 moles of gas

Explanation:

The number of moles of gas in a container can be determined using the Ideal Gas Law, which states that PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature in Kelvins.

We know that:

V = 60.8 L

P = 2.44 atm

T = 275 K

R = 0.0821 L·atm/mol·K

We can rearrange the Ideal Gas Law to solve for n:

n = PV/RT

We can substitute in the given values to find the number of moles of gas:

n = (2.44 atm)(60.8 L) / (0.0821 L·atm/mol·K)(275 K)

n = (2.44)(60.8) / (0.0821)(275)

n = approx. 24.7 mol

Therefore, there are approximately 24.7 moles of gas in the container at the given temperature and pressure.

which example best distinguishes filter bubbles and echo chambers according to the study guide?

Answers

A filter bubble involves the personalization of information through algorithms, while an echo chamber refers to the reinforcement of beliefs through interactions with like-minded individuals.

Filter bubbles and echo chambers are similar concepts, but they can be distinguished based on the mechanism by which information is filtered.

A filter bubble is a situation in which an individual is exposed only to information that is in line with their personal beliefs and opinions. This occurs when online algorithms, such as those used by search engines and social media platforms, prioritize content that is likely to be of interest to the user based on their previous behavior and preferences. This creates a personalized information environment that can limit exposure to diverse perspectives and ideas.

An echo chamber, on the other hand, refers to a situation in which individuals primarily interact with others who hold similar beliefs and opinions. This often occurs in online communities, such as social media groups or forums, where like-minded individuals gather to discuss and reinforce their shared beliefs. Within an echo chamber, it can be difficult for new or alternative viewpoints to penetrate and be heard.

An example that distinguishes filter bubbles and echo chambers is a person who only gets their news from a conservative news outlet, such as Fox News, and interacts primarily with friends who also share their political views on social media. This person is experiencing both a filter bubble, as the news source they use prioritizes content that aligns with their political beliefs, and an echo chamber, as they are only interacting with others who hold similar views.
