What mass of oxygen (O2) forms in a reaction that forms 15.90 g C6H12O6?
Genrish500 [490]
To answer this question, you need to know the chemical equation for making glucose. It should be look like this

 C6H12O6<span>(s) + 6O2(g) -->6CO2(g) + 6H2O(g)

In the equation, the amount of glucose (</span>C6H12O6) is 1 and the amount of oxygen(O2) is 6. But the equation ratio is using moles as a unit. A mole of glucose will weight 180g but a mole of oxygen weight 32g. 

Then, the amount of oxygen forms would be: 6/1 * (15.90g/180g) * 32g= 16.96 grams

Complete the sentences to explain whether molar volumes in the solid state are as similar as they are in the gaseous state and w
Inessa05 [86]

Answer:

Thus, molar volumes of the liquids are expected to be closer to those in the "solid state."

Explanation:

Anything which occupies mass is known as the matter and we know that matter is existed in three states i.e. solid, liquid and gas. The atoms in the solid are closely packed and therefore, they posses very less kinetic energy. The atoms in liquid state are less closely packed and possess more kinetic energy in comparison to the solid state. The atoms in the gaseous state are loose and possess maximum kinetic energy. The molar volume is the volume occupied by 1 mole of a substance. Solid being compressed will have lesser volume in comparison to the liquid and liquid will have lesser volume in comparison to the gas.

In the solid state, it is expected that the amount of empty space is less than that of the gaseous state, and molar volumes are influenced by molecular characteristics. Thus, solid state molar volumes are not similar to those in the gaseous state. When, comparing empty space in the liquid state, it is expected that space in the liquid phases is less than space in the gaseous phase and equivalent to space to the solid state. Thus, molar volumes of the liquids are expected to be closer to those in the solid state.
