5. A flame test can be used to identify an unknown element. A student reacts two chemicals and decides to perform a flame test on the resulting product. If the product gives off a magenta hue when in flames, which element is likely to be present? Use your lab data to help determine the identity of this element.

The element that is likely to be present is LITHIUM.

Explanation:  ABOUT FLAME TEST

An analytical chemistry method used to help identify metal ions is the flame test. It can not be used to classify all metals, although it is a useful qualitative research test and a lot of fun to perform, since not all metal ions emit flame colors. Some metal ions also display colors similar to each other, making it difficult to tell them apart. However, for the detection of various metals and metalloids, the test is still useful.

One downside of the flame test is that the light color that is detected depends very much on the flame's chemical composition (the fuel that is being burned). This makes it difficult to match colors with a chart that has a high level of trust.

The bead test or blister test, in which a bead of salt is coated with the sample and then heated with a Bunsen burner flame, is an alternative to the flame test. Because more samples stick to the bead than to a simple wire loop, this test is slightly more accurate and Since most Bunsen burners, which appear to burn with a clean, blue flame, are linked to natural gas.

      ABOUT LITHIUM ELELMENT -:It's metal, but it's soft enough to cut with a knife .It is so light that water can float on it.   It is hard to put out lithium fires.   Lithium, along with hydrogen and helium, was one of the three elements that the Big Bang produced in vast amounts.

Hence , we identifies the element in flame test by the color produces that is magenta or pink-red which gives the element Lithium . Therefore , the correct answer is lithium.

the solar system used to have much dust particles option no d

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
