coldgirl [10]3 years ago
6 0

Explanation:

<h3>We can observe some physical properties, such as density and color, without changing the physical state of the matter observed. Other physical properties, such as the melting temperature of iron or the freezing temperature of water, can only be observed as matter undergoes. A physical change physical change involves a change in physical properties. Examples of physical properties include melting, transition to a gas, change of strength, change of durability, changes to crystal form, textural change, shape, size, color, volume and density.</h3>

Arrange the following compounds from left to right in order of increasing percentage by mass of hydrogen: a) H2O, b) C12H26, c)
Nuetrik [128]

Answer:

(A) N4H6  (B) H2O  (C) LiH  (D) C12H26

Explanation:

The given compounds have been arranged  from left to right in order of increasing percentage by mass of hydrogen.

The percent by mass of hydrogen can be calculated by mass of hydrogen in that compound divided by total mass of that compound and finally multiplying the result with 100 to obtain the required percentage.

In most lewis dot structures of neutral compounds, carbon as the central atom will be bound to a maximum of how many atoms, nitr
Fittoniya [83]
The total number of elements that one particular element can bond to can be determined by simply drawing the Lewis structure of the element.

Place the chemical symbol
Then look at the group number = valence electrons
Distribute the valence electrons around the atom.

C = 4 bonds
N = 3 bonds
O = 2 bonds

If chromium(II) iodide is dissolved in water you can say that the equilibrium concentrations of chromium(II) and iodide ions are
jenyasd209 [6]

Answer:

See explanation.

Explanation:

Hello there!

In this case, according to the given information, it turns out firstly necessary for us to set up the equilibrium reaction by which chromium (II) iodide is ionized as follows:

CrI_2(s)\rightarrow Cr^{2+}(aq)+2I^-(aq)

Thus, it is possible to notice that the the moles, and therefore concentrations, of chromium(II) and iodide ions are going to be different, by a factor of 2 due to the mole ratio in the aforementioned chemical equation.

Regards!

What properties does iron have that are unusual for metal
natta225 [31]

Iron is constantly working to support life on Earth, from supplying plants with nutrients to serving as a key component of steel to carrying oxygen in your blood.

  • Iron is the most common metal, its pure form corrodes quickly when exposed to humid air and high temperatures.
  • it is abundant in the sun and stars.
  • It contributes to the synthesis of chlorophyll in plants.
  • It is a part of hemoglobin, a blood protein that transports oxygen from the lungs to the body's tissues in mammals.
  • The majority of it is used to create steel, an iron and carbon alloy used in manufacturing.
  • There are four main structural forms of iron, known as allotropic forms, in which atoms are bound in various ways.

These are few properties of iron that are unusual for metal.
