Answer:

The answer to your question is Mercury

Explanation:

The flame test essay is used to identify the identity of a substance because most elements show different colors when in flame.

There are many elements that burn violet when in flame especially elements of the group IA like Potassium, Rubidium, Cesium and also Cyanide and Mercury located in different groups.

But the bibliography tells us that Mercury chloride burns violet so this element is the correct answer because there is chloride in the sample of this question.

Natasha_Volkova [10]

Main advantages of DDT are the insecticide property and the knoledge about its chemical synthesis.

Explanation:

At that time in 1939 it was discovered that DDT have insecticide properties. It is a useful property because it allows inhibition of insects populations in large areas. Killing insects will reduce the diseases transmitted by them as  typhus and malaria. More over you prevent the destruction of the agricultural crops by the harmful insects.

However the synthesis of the molecule was known way back in 1874. From that time it was plenty of time in which chemistry knowledge evolved so the synthesis at kilograms scale was implemented. High quantities of DDT molecule become available for the market so that in 1945 was available as agricultural insecticide.

It was discovered that DDT have bad effects for human health and also over time some insects developed resistance and their were not affected anymore by the molecule.

You may find the chemical structure of DDT in the attached figure.

Silicon Tetrachloride is reacted with very pure magnesium, producing silicon and magnesium chloride. (What would be the unbalanc
raketka [301]
Pure magnesium's formula would just be Mg because all elements except for 7 nonmetals are just left alone when they are by themselves in a formula. The 7 diatomic elements( means they have to have two of them without another element attached to it aka. a subscript two after it when it's by itself) are hydrogen, nitrogen, oxygen, fluorine, chlorine, bromine, and iodine. An easy way to remember the diatomic seven is that when looking at a periodic table if you trace over them from nitrogen over to fluorine and down to iodine all of those elements are diatomic + hydrogen. 

And your unbalanced and balanced equations are correct.

(sorry I went on a tangent with the diatomic rules hopefully it will help you in the future though)

In the reaction 2Mg (s) + O2 (g) + 2H2O (l) → 2Mg2+ (aq) + 4OH– (aq), which substance is reduced?
Bogdan [553]

F. <em>None of the above </em>

<em>No O atoms are present</em> as reacting substances, only O_2 and H_2O molecules.

O_2 + 2H_2O + 2e^(-) → 4OH^(-)

We must use <em>oxidation numbers</em> to decide whether oxygen or water is the substance reduced.

The oxidation number of O changes from 0 in O_2 to -2 in OH^(-).

A decrease in oxidation number is <em>reduction</em>, so O_2 is the substance  reduced.

The oxidation number of O is -2 in both H_2O and OH^(-), so water is <em>neither oxidized nor reduced</em>.
