Answer : The percent composition of hydrogen in benzene is, 7.69 %

Explanation: Given,

Molar mass of C = 12 g/mole

Molar mass of H = 1 g/mole

First we have to calculate the molar mass of benzene.

Molar mass of benzene(C_6H_6) = 6(12)+6(1)=78g/mole

Now we have to calculate the percent composition of hydrogen in benzene.

As we now that there are 6 number of carbon atoms and 6 number of hydrogen atoms.

The mass of hydrogen = 6\times 1=6g

Formula used :

\%\text{ Composition of hydrogen}=\frac{\text{Mass of hydrogen}}{\text{Molar mass of hydrogen}}\times 100

Now put all the given values in this formula, we get the percent composition of hydrogen in benzene.

\%\text{ Composition of hydrogen}=\frac{6}{78}\times 100=7.69\%

Therefore, the percent composition of hydrogen in benzene is, 7.69 %

lora16 [44]
<h2>Answer:</h2>

An Aquifer

<h2>Explanation:</h2>

An aquifer is an underground layer of water-bearing permeable rock or unconsolidated materials like gravel, sand, or silt. The most common aquifers are unconsolidated sands and gravels, permeable sedimentary rocks such as sandstones or limestones and heavily fractured volcanic and crystalline rocks. All of these aquifers can be used for the purification of groundwater contaminated by sewage from a ruptured septic tank.

Match each element to the number of electrons in its valence shell
blondinia [14]

Answer: Be= 2, C =4,  Li = 1 and  B=3

Explanation:

The valence shell can be define as the outermost shell of an atom that contains the valence electrons.

Beryllium (Be), electronic configuration; 1s2 2s2, = 2 electrons in its valence shell.

Carbon (C), electronic configuration; 1s2 2s2 2p2, = 4 electrons in its valence shell.

Lithium (Li), electronic configuration; 1s2 2s1 = 1 electron in its valence shell.

Boron (B) , electronic configuration; 1s2 2s2 2p1 = 3 electron in its valence shell.

Which explains how burning a magnesium ribbon highlights a toolmark?
Setler [38]
<h2>Answer:</h2>

The magnesium ribbon, <u>D. It forms a material to cast the tool mark</u>.

<h2>Explanation:</h2>

When a magnesium ribbon is burnt in the presence of oxygen it gives out strong light and heat is produced. Apart from it, it leads to the production of substance called as magnesium oxide which is formed as the product due to the reaction of magnesium with the oxygen present in the air.

Tool marks are the mark which is created by tools while using them. In order to identify or locate them castes made up of magnesium oxide is utilized. When this is pasted on the suspected area, the tool mark of the suspected tool gets pasted on it.
