Answer: Pink Quartz

Explanation:

Quartz. Can come on different colours like pink, white, gray, purple, black, yellow or green.

<u>Luster</u> means Appearance, Quartz unlike Silica, looks like glass.

<u>Conchoidal fracture: </u>It´s how Quartz´s surface fractures on a smoothly curved way.

Hardness is mineral´s property of being scratched by others. Mohs scale of mineral hardness is used to classify a mineral as softer or not. In this case, quartz has a hardness of 7, that means it´s quite hard, since the scale starts in 1 and finishes in 10.

Answer:

2 C₄H₁₀ + 13 O₂ → 8 CO₂ + 10 H₂O

Explanation:

Step 1: Write the unbalanced chemical equation,

C₄H₁₀ + O₂ → CO₂ + H₂O

Step 2: Balance Carbon Atoms;

As there are 4 carbon atoms on left hand side and 1 carbon atoms on right hand site therefore, to balance them multiply CO₂ on right hand side by 4 i.e.

C₄H₁₀ + O₂ → 4 CO₂ + H₂O

Step 3: Balance Hydrogen Atoms;

There are 10 hydrogen atoms on left hand side and 2 hydrogen atom on right hand site therefore, to balance them multiply H₂O on left hand side by 5 i.e.

C₄H₁₀ + O₂ → 4 CO₂ + 5 H₂O

Step 4: Balance Oxygen Atoms:

Now there are 2 oxygen atoms in reactant side and 13 in product side. So, multiply O₂ by 6.5 i.e.

C₄H₁₀ + 6.5 O₂ → 4 CO₂ + 5 H₂O

Step 5: Remove fraction coefficients as,

Multiply whole equation by 2 to get rid of fractions i.e.

2 C₄H₁₀ + 13 O₂ → 8 CO₂ + 10 H₂O

Three test tubes contain white crystalline organic solids A, B, and C, each of which melts at 149-150 degrees C. A 50-50 mixture

Digiron [165]

Answer:

The mixture of B and C will melt as 130 - 139 ºC.

Explanation:

If the melting point (130 - 139 ºC) of a mixture of A and B is lower than the pure substances that is 149 - 150 ºC that means that one of these susbtances is an impurity because reduces the melting point.

If the melting point of the mixture of A and C is the same as the pure substances, we can deduce that they are the same substances, also because the melting point when a substance is pure is just 1 or 2 ºC like in this case.

So in a Mixture of B and C is going to be like the first case of the mixture among A and B, because the B substance is the impurity.
