Answer:

Mineral Content.

Explanation:

shape has nothing to do with the color displayed.

Nor does the grain size.

I don't know what banding is. Whatever it is, it is not the answer.

D: mineral content.

How many atoms are in 6.28 moles of aluminum
tensa zangetsu [6.8K]

Answer:

3.78 x 10^24

Explanation:

I mol = 6.02X10^23 atoms

So,

6.28 mol A l    \frac{6.022 x 10^{23}}{1 mol}    = 3.78 x 10^{24} I did not round the last number

the full answer was, 3.78056 x 10^24

Which observation most likely indicates that only a chemical change has taken place
salantis [7]

The correct answer as to which observation most likely indicates that only a chemical change has taken place would that the change cannot be reversed.

When it comes to changes in a system, it can either be:

  • physical change
  • chemical change

When a substance undergoes a physical change, the original version of the substance can be recovered. In other words, physical changes can be reversible.

When a substance undergoes a chemical change, the original version cannot be recovered because an entirely new product would have been formed. In other words, chemical changes are irreversible.

Thus, once a change becomes irreversible, such a change is said to be a chemical change.

The mass of ethanol (alcohol) = 538.016 g

<h3>Further explanation</h3>

Given

Reaction

C₁₂H₂₂O₁₁(aq)+H₂O(I) = CH₃CH₂OH(aq)+CO₂(g)

1 kg of sugar = 1000 g

Required

The mass of ethanol

Solution

Balanced equation

C₁₂H₂₂O₁₁(aq)+H₂O(I) = 4CH₃CH₂OH(aq)+4CO₂(g)

mol of sugar (MW = 12.12+22.1+11.16=342 g/mol) :

mol = mass : MW

mol = 1000 g : 342 g/mol

mol = 2.924

From the equation, mol ratio of C₁₂H₂₂O₁₁ : CH₃CH₂OH = 1 : 4, so mol ethanol =

= 4 x mol sugar

= 4 x 2.924

= 11.696

Mass of ethanol(MW=46 g/mol) :

mass = mol x MW

mass = 11.696 x 46

mass = 538.016 g
