Answer:

The correct answer is: their composition.

Explanation:

The mineral classification is based on the chemical composition and internal structure, which together represent the essence of a mineral and determine its physical properties. According to the chemical composition, minerals are divided into classes according to the dominant anion or anionic group, for example, oxides, halides, sulphides and silicates, among others.

Minerals have the same anion or dominant anionic group in their composition, so they have family similarities and characteristics more clearly and strongly marked than those that share minerals that have the same dominant cation. Examples of this are carbonates, since they resemble each other more than copper ores.

Minerals related by the domain of the same anion tend to occur together in the same place or in similar geological deposits; for example, sulphides generally occur in associations close to deposits of the type of veins or replacement, while silicates form most of the rocks in the earth's crust.

KE and PE Math

slava [35]

Answer:

1. Answer: The bowling ball has more potential energy as it sits on top of the building. It does not have any kinetic energy because it is not moving.

2. Answer: The bowling ball has equal amounts of potential and kinetic energy half way through the fall. At the half way point, half of the potential energy has been converted to kinetic energy.

3. Answer: Just before the ball hits the ground, it has more kinetic energy. As it hits the ground the potential energy becomes zero.

4. Answer:

PE=784 J

5. Answer:

PE = 392 J

6. Answer:

KE= 392 J

Also, since the PE and KE are equal at the half way point and PE =392 J, KE = 392 J.

7. What is the kinetic energy of the ball just before it hits the ground?

Answer:

KE=784 J

Which statement is true about a reversible reaction?

bonufazy [111]

Answer:

The correct statement is : It results in an equilibrium mixture of reactants and products.

Explanation:

A reversible chemical reaction is one that occurs in both directions, that is, of the reagents to generate products and vice versa. In synthesis, they are incomplete reactions since the reagents are not consumed in their entirety, since the products react to generate them again.

A scientist produces zinc iodide (zni2). (a) calculate the minimum mass of zinc that needs to be added to 0.500 g of iodine so t

harina [27]

The minimum mass of Zinc, Zn that needs to be added to 0.500 g of iodine so that the iodine fully reacts is 0.128 g

<h3>Balanced equation </h3>

Zn + I₂ —> ZnI₂

Molar mass of Zn = 65 g/mol

Mass of Zn from the balanced equation = 1 × 65 = 65 g

Molar mass of I₂ = 127 × 2 = 254 g/mol

Mass of I₂ from the balanced equation = 1 254 = 254 g

SUMMARY

From the balanced equation above,

254 g of I₂ required 65 g of Zn

<h3>How to determine the mass of Zn needed </h3>

From the balanced equation above,

254 g of I₂ required 65 g of Zn

Therefore,

0.5 g of I₂ will require = (0.5 × 65) / 254 = 0.128 g of Zn

Thus, the minimum mass of Zn required is 0.128 g
