UNO [17]2 years ago
8 0

Answer: arrangement of constituent particles makes glass diff. from quartz. Glass-short range order of particles.
Quartz-Long range of particles.

If quartz is heated and cooled rapidly it can be converted to glass.

In the oxidation reduction reaction 2FeCl2 + Cl2 = 2FeCl3 what substance is reduced? What substance is oxidized?
marishachu [46]

Answer:

Iron is oxidized while chlorine is reduced.

Explanation:

The oxidation reduction reactions are called redox reaction. These reactions are take place by gaining or losing the electrons and oxidation state of elements are changed.

Oxidation:

Oxidation involve the removal of electrons and oxidation state of atom of an element is increased.

Reduction:

Reduction involve the gain of electron and oxidation number is decreased.

Consider the following reaction:

2FeCl₂  + Cl₂  →  2FeCl₃

in this reaction the oxidation state of iron is increased from +2 to +3. That's why iron get oxidized and it is reducing agent because it reduced the chlorine. The chlorine is reduced from -2 to -3 and it is oxidizing agent because it oxidized the iron.

2Fe⁺²Cl₂⁻²

2Fe⁺³Cl₃⁻³

The iron atom gives it three electrons to three atoms of chlorine and gain positive charge while chlorine atom accept the electron and form anion.

Will an empty balloon have precisely the same apparent weight on a scale as a balloon filled with air? Explain.
hram777 [196]
The notion <span>an empty balloon have precisely the same apparent weight on a scale as a balloon filled with air depends on the diameter of the balloon. The weight of the balloon  filled with air is equal to the mass of the balloon and the mass of the air inside. The mass of air inside is equal to the density of air multiplied by the volume of the balloon. If the balloon is large, then the two masses are equal whereas if not, the mass of air inside the inflation is neglible</span>

A typical coffee mug holds about 355,000 microliters of liquid. How many kiloliters of liquid does this mug hold expressed in st
skad [1K]

Answer:

3.55\times 10^{-4}\ kL

Explanation:

Given that,

A typical coffee mug holds about 355,000 microliters of liquid.

1\ \mu L=10^{-6}\ L

Also, 1 L = 0.001 kL

10^{-6}\ L=0.001\times 10^{-6}\ kL\\\\=10^{-9}\ kL

So, a typical coffee mug holds about 355000 \times 10^{-9}\ kL or 0.000355\ kL of liquid.

We need to convert it into Scientific notation.

We will shift 4 zeros to right. As a result,

V=3.55\times 10^{-4}\ kL

So, the mug will hold 3.55\times 10^{-4}\ kL of liquid.
