Sodium (Na) and iodine gas (I2) react to form sodium iodine (NaI) .

Chemistry

Answer:

2Na +  I₂  → 2NaI

Explanation:

The sodium and iodine gas react to form the sodium iodine, correct chemical equation is given below:

2Na +  I₂  → 2NaI

All other equations are incorrect because,

NaI → 2Na + I₂

In this equation sodium iodine split to gives sodium and iodine.

Na  → NaI + I₂

This equation is incorrect because just one element sodium produces sodium iodine and iodine which is impossible.

I₂  →  2NaI + 2Na

This equation is also incorrect because just one element iodine produces sodium iodine and iodine which is impossible, because if there is no sodium atom present in reactant side then it would not appear in product.

Could two objects with the same volume have different masses? Which, if either, would contain more matter?
kipiarov [429]

Answer:  Yes, two objects may have the same volume while having different masses. The object with a greater mass will be the one that contains more matter.

Explanation: Mass and volume are two different properties of matter. Mass is defined as the amount of matter that a body has. Volume is defined as the amount of space that a body occupies. Density is the property that relates mass with volume as

Density=Mass/Volume

and is defined as the amount of matter that exists in a certain amount of space.

Because mass and volume are independent from each other, we can say that two objects can have different masses and have the same volume.

<u>For example</u>, imagine two identical containers that weigh the same and that are capable of containing a volume of 1 liter each. Then, one of the containers is filled with water, while the other one is filled with mercury. In this case the volume of the water and the volume of the mercury will be the same: 1 liter, however, if we weigh the containers again, we will find that the one that has mercury is heavier than the one that has water. This is due to the density of mercury being higher than the density of water. In other words, 1 liter of mercury provides more mass than the mass provided by 1 liter of water.

Then, according to the definition of mass, the object that contains more matter will be the one that has more mass, in the case of our example, that would be the liter of mercury.

Anhydrous calcium chloride removes water vapor from the air inside a container having an air-tight seal called a desiccator. Exp
OlgaM077 [116]
Hello!

The anhydrous calcium chloride (CaCl₂) is a hygroscopic substance. That means that the substance has a very high affinity with water (H₂O).

Water vapor from the air reacts with CaCl₂ to form Hydrated complexes following this reaction:

CaCl₂ + nH₂O → CaCl₂*nH₂O

In this reaction, water vapor is consumed and removed from the air, lowering the humidity of the air inside the desiccator.
