Does hydrogen have 1 or 2 valence electrons?.
Hydrogen has a single atomic nucleus. Therefore, there will be one electron overall and one valence electron.
Chemistry's concept of valence, sometimes written as valency, refers to an element's ability to mix with a certain number of other atoms. The phrase, which was first used in 1868, can describe both the general power of the combination of an element as well as the numerical magnitude of that power of combination.
A significant issue for 19th-century chemists was explaining and organizing valence. The focus of the majority of the work was on developing empirical guidelines for figuring out the valences of the elements because there was no good hypothesis explaining their origin. Characteristic valences for the elements were calculated based on how many hydrogen atoms each one of their atoms might mix with.

Any help is greatly appreciated and will leave a positive review! 1) Identify the type(s) of motion that individual molecules can undergo in a molecular solid. 2) When the temperature of a solid copper pipe increase, does the motion of the free electrons increase, decrease, or remain the same? 3) Draw particulate representations of a molecular liquid at a low temperature and a high temperature. Use arrows to represent velocity vectors. 4) Draw particulate representations of molecular gas at a low temperature and a high temperature. Use arrows to represent velocity vectors. 5) Draw a particulate representation of a 1.0 L sample of molecular gas in a cylinder. Draw a second particulate representation of the same sample of gas after it has been compressed to 0.5 liters. Assume that the temperature remains the same. Use arrows to represent velocity vectors. 6) Draw particulate representations that show the differences between a solid, liquid, and gas. Particle motion, intermolecular forces, and overall volume must be highlighted in the representations.
In a molecular solid, individual molecules can undergo various types of motion, including translational motion (movement from one point to another), rotational motion (spinning around a fixed axis), and vibrational motion (oscillating or shaking about a fixed position).
When the temperature of a solid copper pipe increases, the motion of the free electrons within the copper atoms will also increase. This is because an increase in temperature corresponds to an increase in the kinetic energy of the particles in a substance, which leads to an increase in their motion.
In a molecular liquid at a low temperature, the individual molecules will be moving relatively slowly, with relatively low velocities. The arrows representing the velocity vectors of the molecules will be relatively small and widely spaced.
In a molecular liquid at a high temperature, the molecules will be moving more quickly, with higher velocities. The arrows representing the velocity vectors of the molecules will be larger and more closely spaced.
In a molecular gas at a low temperature, the individual molecules will be moving relatively slowly, with relatively low velocities. The arrows representing the velocity vectors of the molecules will be relatively small and widely spaced.
In a molecular gas at a high temperature, the molecules will be moving more quickly, with higher velocities. The arrows representing the velocity vectors of the molecules will be larger and more closely spaced.
In a particulate representation of a 1.0 L sample of molecular gas, the individual molecules will be spaced relatively far apart from each other, with relatively low velocities. The arrows representing the velocity vectors of the molecules will be relatively small and widely spaced.
In a particulate representation of the same sample of gas after it has been compressed to 0.5 liters, the molecules will be spaced much closer together, with higher velocities. The arrows representing the velocity vectors of the molecules will be larger and more closely spaced.
In a particulate representation of a solid, the individual particles will be closely packed together in a regular, ordered arrangement. The particles will be vibrating in place, with little overall movement or change in position. In a particulate representation of a liquid, the particles will be more loosely packed together, with more freedom of movement.
The particles will be moving and flowing past each other, with relatively low velocities. In a particulate representation of a gas, the particles will be spaced far apart from each other, with a large amount of empty space between them. The particles will be moving quickly and randomly in all directions, with relatively high velocities.

what is the vapor pressure of a solution prepared by dissolving 0.750 moles of c6h12o6 in 5.50 moles of water at 25oc? the vapor pressure of water at 25oc is 23.8 mmhg.
The ratio of partial pressure of the solute to the total pressure will be equal to its mole fraction by which, the partial pressure obtained for C₆H₁₂O₆ is 3.24 mmHg.
What is partial pressure ?Partial pressure of a component in a mixture is the pressure contributed by the component to the total pressure of the mixture. Thus, the partial pressure of a solute contributes to the total pressure in solution.
The mole fraction of a component A in a mixture containing A and B is equal to the ratio of the its partial pressure to the total pressure.
nA / (nA + nB) = pA / pA + pB.
Let pA be the partial pressure of C₆H₁₂O₆ and partial pressure of water is given 23.8 mmHg, then pA is calculated as :
0.750 /(5.50 + 0.750 ) = pA / (pA + 23.8 mmHg)
0.12 = pA / (pA + 23.8 mmHg)
pA = 0.12 pA + 2.856

acetic acid is a covalent compound but, when dissolved in water, it is a weak electrolyte. how would you explain this phenomenon?
Acetic acid is a covalent compound but, when dissolved in water, it is a weak electrolyte. It is a vulnerable electrolyte for the reason that compound does now no longer dissociate absolutely to shape ions.
Electrolytes are materials which could behavior power while they may be located in solution. This is because of their capacity to provide charged debris in solution.
These debris are referred to as ions. Acetic acid is a vulnerable acid because it partly dissociates in water ensuing withinside the formation of acetate and hydronium ions. It is a vulnerable electrolyte for the reason that compound does now no longer dissociate absolutely to shape ions.

how much water remains unfrozen after 50.2 kj is transferred as heat from 260 g of liquid water initially at its freezing point?
109 g of water remains unfrozen after transferring 50.2 kj of heat from 260 g of liquid water.
What is freezing point?A liquid turns into a solid at the freezing point. Increased pressure typically causes the freezing point to rise, just like it does for the melting point. Combinations and some organic substances, such as fats, have a freezing point that is lower than their melting points.Every substance has a freezing point, which is the point at which it changes from a liquid to a solid. Since the liquids can be rapidly chilled below their freezing points, they don't solidify until temperatures considerably below freezing.Here given ,
The volume of frozen water is m.
m = LFQ
= 333 kJ/kg x 50.2 kJ
= 0.151 kg
= 151 g.
Consequently, the volume of water that is still liquid is :
260 g − 151 g
= 109 g.
Therefore 109 g of water remains unfrozen.

in a gas mixture, the partial pressures are nitrogen 423 torr , oxygen 149 torr , and helium 255 torr . part a what is the total pressure, in torr, exerted by the gas mixture? express your answer to three significant figures and include the appropriate units
827.0 torr is the total pressure, in torr, exerted by the gas mixture
The partial pressures of the individual gases make up the total pressure of the gas mixture.
Total pressure= sum of all partial pressure
Total pressure=423+149+255
Total pressure= 827.0 torr
Pressure is defined as force/area. To illustrate the pressure from snow on a roof, divide the weight of the snow by the surface area of the roof. Gases are a typical pressure source in chemistry. A "vacuum" is used to describe the absence of pressure. Humans have long held the belief that vacuums are both improbably rare and unnatural because "nature abhors a vacuum." Actually, this is not the case.
The number of pressure units is ridiculous. It's common to use the torr or mmHg unit. This discussion is solely focused on the height of a mercury column. The atmosphere contains 760 torr, or mmHg. You might also look at mmH2O, which makes use of a related idea.
