When a bond between a hydrogen atom and a sulfur atom is formed, electrons are?

How many different flame colors were you able to detect? How many different elements must have been exposed to the flame to prod

Bogdan [553]

Answer:

This question is incomplete

Explanation:

This question is incomplete, however, there are some basic things that be used to answer the completed question on your own. Flame test is a test that is used to identify metal ions in a compound. Although, not all metal ions produce a colour in a flame test.

In a flame test, a "clean wire loop" is dipped in an unknown solid/mixture of solids, the loop where the solids must have attached to is then placed in the tip of a blue flame (perhaps of a bunsen burner). A colour change/changes is then observed during the course of this process. Some popular metal ions and there colour in flame test are listed below

Lithium ion ⇒ red

Sodium ion ⇒ yellow

Potassium ion ⇒ lilac

Calcium ion ⇒ orange-red

Barium ion ⇒ pale-green

Copper ion ⇒ blue-green

rubidium ion ⇒ red-violet

Lead ion ⇒ gray white

The number of different colours observed will ultimately determine the number of elements exposed to the flame

Determine the latitude and longitude of the location A

malfutka [58]

Answer:

Latitude: $30\° N$

Longitude: $45\° W$

Explanation:

Lets begin by explaining the meaning of latitude and longitude as geogrephical coordinates:

Latitude is the angular distance between the equatorial line, and a specific point on the Earth. It is measured in degrees and is represented according to the hemisphere in which the point is located, which can be north or south latitude.

In this sense latitude $0\°$ refers to the equatorial line that divides the Earth in two hemispheres (North and South).

Longitude represents the specific east–west position of a point on the Earth's surface, being longitude $0\°$ the prime meridian or Greenwich meridian.

So, according to the figure, where the model of the Earth is divided by latitude lines separated by $10\°$ and the longitude lines separated by $15\°$ ; we only have to count the lines from the equator to the line where the point A is, and count the lines fromo the Prime meridian to the line where point A is located.

Hence, point A location is:

Latitude: $30\° N$

Longitude: $45\° W$

Which of the following lists the elements in order of increasing malleability?

Juliette [100K]

The answer would be (B) Sb, Sn, Se.

The periodic table may look like a confusing checkerboard of elements, but they are categorized in more ways than you may know.

For malleability, we look for metals. Metals/metallic elements have characteristics like electrical conductivity, <u>malleability</u>, ductility, and other physical characteristics like luster. The more an element is metallic, the more of these characteristics it will have.

So to answer this question, you simply have to see what kind of elements these are:

Sb, 51 (Antimony): <em>Metalloid</em>

Sn, 50 (Tin): <em>Transition Metal</em>

Se, 34 (Selenium): <em>Non-Metal</em>

Therefore, Antimony will have more metal characteristics than the rest, putting it at the top. Selenium is a non-metal, so that goes at the bottom, and Tin will be second.

What is a substance's melting point?

TEA [102]

A melting point of a substance is a point at which the sample or substance start converting in liquid. For most substances, melting and freezing points are approximately equal. For example, the melting point and freezing point of mercury is 234.32 kelvins (−38.83 °C or −37.89 °F). Hope this helped!! :)
