Answer:

its sodium hydroxide

Explanation:

All of the above options would change the vapor pressure of a sample of water in a closed container.

Vapor pressure is a measure of the tendency of a substance to turn into a gas at a given temperature. It is related to the kinetic energy of the molecules of the substance, with more energetic molecules having a higher vapor pressure. In a closed container, the vapor pressure of a liquid will be determined by the temperature and the number of molecules present.

It's also worth noting that the vapor pressure of a liquid is also related to its boiling point. The boiling point is the temperature at which the vapor pressure of a liquid equals the atmospheric pressure. As the vapor pressure of liquid increases, its boiling point increases, and as the vapor pressure decreases, its boiling point decreases.

Answer:

This is a problem involving Charles's Law, which states that at constant pressure, the volume of a fixed mass of gas is directly proportional to its absolute temperature. The equation is:V1/T1 = V2/T2where V1 and T1 are the initial volume and temperature, respectively, and V2 and T2 are the final volume and temperature, respectively.We can rearrange this equation to solve for T2:T2 = (V2/T1) x T1First, we need to convert the initial temperature to Kelvin:T1 = 35 ºC + 273.15 = 308.15 KNow we can plug in the values and solve for T2:T2 = (750 mL/500 mL) x 308.15 K

T2 = 462.23 KFinally, we convert the temperature back to Celsius:T2 = 462.23 K - 273.15 = 189.08 ºCTherefore, the new temperature of the carbon monoxide gas is approximately 189.08 ºC when the volume is increased to 750mL

Answer:

If there are more products than reactants, that means the reaction has shifted towards the left, which is the backward direction. If there are more reactants than products, that means the reaction has shifted towards the right, which is the forward direction.

When a gas flow from the smaller container to larger container the pressure applied by the gas on the container will decrease.

What is pressure?

The force applied across a given area is referred to as pressure. Pascals (Pa), newtons per square meter (N/m2 or kg/ms2), or pounds per square inch are common measurements used to express pressure. The atmosphere (atm), torr, bar, and meters sea water are additional units (msw).

According to gas law,

i.e. P V = n R T

{ where, P = pressure,

V = volume,

n = number of moles,

T = temperature

R = gas constant }  

when temperature and number of moles are held constant then pressure and volumes has inverse relation ship. i.e. when volume increases pressure decrease and when volume decreases pressure increases. Here, in the case given in question the gas flows towards the larger container which means the volume is increasing so the pressure will decrease.

Answer:

6.2moles of Gold

Explanation:

To solve this problem, we are going to use the mole concept approach.

 Given that;

  Number of atoms of gold is 3.73 x 10²⁴ atoms

Now;

  In 1 mole of any substance, we have 6.02 x 10²³ atoms;

   So;

  If there  6.02 x 10²³ atoms in  1 mole of any substance;

                 3.73 x 10²⁴ atoms will contain  \(\frac{3.73 x 10^{24} }{6.02 x 10^{23} }\)    = 6.2moles of Gold

Answer:

industrial lab safety, therefore, is critical to safeguard the health and well-being of these technicians, as is the protection of equipment, products, samples, supplies and the facility itself. The importance of testing lab safety cannot be overstated; it helps keep all of these components — most notably, workers — out of danger.

Safety is important in middle-school and high-school science labs to ensure students and teachers stay out of harm's way. Science classrooms often have equipment -- such as Bunsen burners, chemicals and sharp tools -- that pose potential hazards if used improperly. Teachers and school administrators don't have the time or the budget to deal with liability lawsuits, and dangerous incidents could damage the school's and the teacher's reputation.

Answer:

Alkali metals

Explanation:

101 mmHg is the total pressure in the tank.

Thus, Dalton's Law of Partial Pressures states that while the volume and temperature of a gaseous mixture are held constant, the total pressure of the mixture is equal to the sum of the partial pressures of its gaseous components.

Nitrogen, oxygen, argon, carbon dioxide, water vapor, and a trace amount of other gases are all present in atmospheric air and pressure.

The increased oxygen content in the chamber can displace the CO bound to hemoglobin faster than air oxygen, hence the hyperbaric chambers are also used to treat carbon monoxide (CO) poisoning. The treatment of scuba divers with the bends is another application for hyperbaric chambers.

Thus, 101 mmHg is the total pressure in the tank.

J.J. Thomson discovered electrons and their negative charge through the cathode ray experiment, leading to the development of the plum pudding model of the atom.

J.J. Thomson, a British physicist, was the first to discover electrons in 1897.

He conducted the cathode ray experiment to identify the negatively charged particles.

The cathode ray tube is a vacuum-sealed glass tube with two electrodes at each end: a cathode and an anode.

When a high voltage electrical current is applied to the electrodes, the tube glows, indicating that the cathode rays are being emitted from the cathode and traveling through the tube towards the anode.

The cathode rays were found to have a negative charge, according to Thomson.

These rays were identified as particles by the presence of a magnet, which caused the particles to bend in the direction opposite to the magnet's polarity.

This discovery indicated that the particles had a charge on them because they were deflected by the magnetic field, which is only possible if the particles have an electric charge.

Thomson further concluded that these particles were about 1,000 times smaller than hydrogen atoms because of the degree of deflection they experienced in the magnetic field.

Furthermore, Thomson created the plum pudding model of an atom, in which electrons are dispersed throughout a positively charged matrix, based on his findings.

Explanation:

Gravity filtration consists of a pump and a filter (to be placed outside the basin, above the water level). The pump is placed in the water. Connected by a hose to the filter, water is sucked up to the device.

In the gravity-type configuration, water is sucked into the filter, which causes an imbalance between the levels of the basin and the filter: this imbalance causes the movement of water - with the dirt - from the basin to the filter via the main drain and the skimmer.
