Calculate the ratio of effusion rates for Ar and Kr?
The ratio of effusion rates for two gases is given by the square root of the inverse ratio of their molar masses. The molar mass of Ar is approximately 40 g/mol, and for Kr it is approximately 84 g/mol. So, the ratio of effusion rates for Ar and Kr is √(84/40) ≈ 1.3.
A carpenter compares the masses of two types of wood. A cubic meter of ash is 540 kg. A cubic meter of willow is 420 kg. What is the ratio of the willow's mass to the ash's mass?
The Answer is 45Kg
What two characteristics of water combine to form a thermohaline?
The two characteristics of water that combine to form a thermohaline current are temperature and salinity. As water becomes cold and more saline, it becomes denser and sinks to the ocean floor, driving the vertical circulation of the ocean known as the thermohaline circulation.
What materials that are made up of two of more pure substance not chemically combined the materials do not have a fixed ratio of elements and can be separated into their by physical means?
Materials composed of two or more pure substances that are not chemically combined are known as mixtures. These mixtures do not have a fixed ratio of components and can be separated by physical means, such as filtration, distillation, or chromatography. Examples include air, salad, and sand and salt mixtures. Unlike compounds, the individual substances in a mixture retain their own properties.
What is a strip of water between two land masses called?
A strip of water between two land masses is called a strait.
Does the ratio of the distances equal to the ratio of the masses in each of the cases?
Yes, according to Newton's law of universal gravitation, the ratio of the distances between two masses is equal to the ratio of the masses. This relationship holds true for gravitational forces acting between any two objects.
Two masses are in the ratio 1 4 what is the ratio of their inertia?
The ratio is the same. Inertia depends entirely on mass.
What two pieces of information are needed to determine the ratio of elements in a compound?
The chemical formula of the compound (e.g., H2O for water) and the molar masses of the elements present in the compound are needed to determine the ratio of elements. The molar masses are required to calculate the molar ratios of the elements in the compound.
Is there more than one way yo get two objects with identical masses?
Yes, you can have two objects with identical masses by either having two objects made from the same material and dimensions or by adjusting the quantities of different materials to have the same mass.
Can two objects with the same volume have different masses if so why?
Yes, two objects with the same volume can have different masses if they are made of materials with different densities. Density is the mass of an object per unit volume, so objects of the same volume but different densities will have different masses.
What is the ratio of forces between two masses kept at a certain distance in the air to the force between them when kept in any other medium?
The ratio of forces between two masses in air to the force between them in any other medium is determined by the medium's relative permittivity or dielectric constant. In a medium with a dielectric constant other than air, the force between the masses will be reduced by a factor equal to the medium's dielectric constant.
What two factors can affect salinity?
Ocean currents,The sun,and human activities
Two planets with simarlar mass and size are?
Uranus and Neptune have similar mass and size. Venus and Earth are actually not as close in terms of mass. Neptune is the heavier of the two gas giants, the ratio of their masses is 0.87, while the mass ratio of Venus to Earth is only 0.82.
What is a likely ratio of the masses of oxygen in two different compounds of tin and oxygen both of which contain the same mass of tin?
The ratio of the masses of oxygen in two different compounds of tin and oxygen is dependent on the specific compound and its chemical formula. Since the mass of tin is the same in both compounds, the ratio will be determined by the chemical composition of each compound. This ratio can be calculated by using the molar mass of oxygen in each compound and comparing it with the molar mass of tin.
Measure of the amount of solids and salt dissolved in seawater?
Salinity
Ratio of gravitational and electrostatic force between two electrons?
The ratio of gravitational force to electrostatic force between two electrons is approximately (3.6 \times 10^{-42}). This is because the gravitational force between two electrons is much weaker than the electrostatic force due to their small masses compared to their charges.
Calculate the ratio of effusion rates for Ar and Kr?
The ratio of effusion rates for two gases is given by the square root of the inverse ratio of their molar masses. The molar mass of Ar is approximately 40 g/mol, and for Kr it is approximately 84 g/mol. So, the ratio of effusion rates for Ar and Kr is √(84/40) ≈ 1.3.
