What are fixed compositions or uniformed compositions?
Fixed or uniform compositions are characteristic of chemical compounds.
Is there any molecule which have no molecular formula but have a empirical formula?
Yes, some molecules have no specific molecular formula but only an empirical formula. These molecules consist of various combinations of atoms and do not have a fixed structure, so a specific molecular formula cannot be determined. Examples include polymers and complex mixtures.
Relationship among molecular interaction and phases of matter?
The molecular interactions between particles determine the physical properties and behavior of different phases of matter. For example, strong intermolecular forces result in solids with fixed shapes and volumes. Weaker forces allow particles to move more freely, leading to liquids with a definite volume but no fixed shape, and gases which have neither fixed shape nor volume.
What is the molar mass of a gas if 1.10g of the gas has a volume of 245mL at STP?
48. Assuming we can use the ideal gas law PV=nRT, we can see that if pressure and temperature are fixed, a gas will assume a volume proportional to the number of moles of that gas present (R is a constant). Oxygen gas (O2) has a molecular mass of 32, so 1 mole of oxygen has a mass of 32g in that volume, whereas your gas has a mass of 48g (as the volume is fixed, multiply the mass by the density difference) so the molecular weight of your gas is 48 - possibly ozone (O3).
What is the molecular movement of melting?
During melting, the molecular movement increases as heat is absorbed, causing the solid's structure to break down. This results in the molecules transitioning from a fixed, orderly arrangement in the solid state to a more disordered, fluid state in the liquid phase.
What are fixed compositions or uniformed compositions?
Fixed or uniform compositions are characteristic of chemical compounds.
What describes a molecular liquid conceptually?
A molecular liquid consists of molecules that are free to move past each other, but are still attracted to each other via intermolecular forces. This allows the liquid to flow and take the shape of its container. Molecular liquids have a fixed volume but not a fixed shape.
Is there any molecule which have no molecular formula but have a empirical formula?
Yes, some molecules have no specific molecular formula but only an empirical formula. These molecules consist of various combinations of atoms and do not have a fixed structure, so a specific molecular formula cannot be determined. Examples include polymers and complex mixtures.
What is the standard weight of a fixed barbell?
The standard weight of a fixed barbell is typically around 45 pounds.
What is the scientific meaning of weight?
Weight is actually force in a fixed setting. In the context of a relatively large and uniform gravitational field (such as being on the surface of the planet), weight is the force along the line between the center of the gravitational field and the center of the object. That is, the weight of an object in such a gravitational field is the strength of that field multiplied by the mass of the object.
Which is a property of a pure substance uniform composition fixed composition varying composition?
A property of a pure substance is fixed composition. This means that the substance is made up of only one type of molecule or atom throughout, with no variation in its chemical composition.
Are adjustable weight dumbells as effective as fixed weight ones?
Adjustable weight dumbbells actually offer more options and flexibility, so they are probably more effective than fixed weight dumbbells.
how much weight can it support?
The is dual sided and can hold 10 fixed barbells or fixed curl bars. It can support 420 lbs of weight.
Is a homogeneous mixture uniform throughout a mixture?
Yes, a homogeneous mixture is uniform throughout, meaning that the components are evenly distributed at a molecular level. This results in a consistent composition and appearance in all parts of the mixture.
What is the differences between uniform motion and uniformly accelerated motion?
In uniform motion, object travel at fixed and constant speed and uniformly accelerated motion the speed of the object increases uniformly.
A compass draws all points at a uniform distance from a fixed point thereby creating a locus of points for a circle?
true
How much weight does a fixed pulley take?
A fixed pulley does not take any weight itself. It redirects the force applied to it, making it easier to lift a heavy object by changing the direction of the pull.
