Which substance is a mixture?<br> table salt<br> gasoline<br> aluminum<br> carbon dioxide
GaryK [48]

Answer:

Gasoline

Explanation:

Pure Substance: are those having same type of atoms or molecules.

Compound: one or more atoms of the element combine to form a compound.

Mixture: is combination of one or more substances mix together.

Homogeneous Mixture: are those which are not distinguish by naked eye but can be separated into its components by physical means

Heterogeneous mixture: are those which can be distinguishing by naked eye and can be separated into its components by physical means.

So keeping in mind the above definitions

Table salt:

The chemical formula of table salt is NaCl and it a pure compound not mixture.

Gasoline:  

Gasoline is mixture of hydrocarbon, It contains small hydrocarbons ranging from 4 Carbon to 12 Carbon per molecule. it is a homogeneous mixture.

Aluminum:

Aluminum is a pure substance that is made up of same kind of atoms. so it is an element and not mixture. Its symbol is Al

Carbon dioxide:

Carbon dioxide is a pure compound and its chemical formula is CO₂ and not a mixture.

So, the write option is Gasoline.

In a capillary tube, how do we tell which side of the meniscus has higher or lower pressure
galina1969 [7]

Answer:

A liquid with a sharp contact angle (e.g., water on glass) will form a concave meniscus, and the liquid pressure under the meniscus will be smaller than the atmospheric pressure

Explanation:

The phenomenon of capillarity is produced by the action of the surface tension of the fluids and is observed when a small diameter tube is immersed within the fluid. If we pay attention to the result, we can see that, depending on the fluid, two different things can happen, that the liquid rises through the tube and that the level inside the tube is greater than that of the liquid or that the opposite happens.

The case in which the liquid rises above the tube occurs when the liquid "wets". This occurs when the adhesion forces with the walls exceed those of cohesion between the fluid molecules. In this case, the concave side is out of the fluid.

The case where the level of the liquid inside the tube is lower than the level of the liquid occurs when the liquid does not get wet. We remember that the liquid does not get wet when the cohesion forces are greater than those of adhesion. This phenomenon is called capillary depression and the concave angle is for the liquid side and is said to be convex.

Kilograms represented by the mass defect for oxygen-16: 2.20 × 10 -28 kg what is the nuclear binding energy for oxygen-16? 3.0 ×
USPshnik [31]

From the calculation, the binding energy of the oxygen atom is 1.98 * 10^11 J

<h3>What is the binding energy?</h3>

The term binding energy has to do with the energy that must be supplied to the nucleus of an atom for the nucleus of the atoms to be bonded together.

We must note that;

E = mc^2

E =  2.20 × 10 -28 kg * ( 3 * 10^8m/s)^2 = 1.98 * 10^11 J
