Answer:
An example of a metal with an organic radical is: Pentamethylcyclopentadiene, which is the union between Zinc and an organic compound, where in order to obtain it there is a release of dihydrogen.
Another example is lead tetraethyl, it is a compound for industrial use, it is dangerous for the human body, toxic and can be used as fuel.
Explanation:
In radical chemistry a chemical species is called both organic and inorganic, which one of the most used examples is methyl, where it is a chemical structure that has one carbon and 4 hydrogens attached to this central carbon.
These chemical compounds when united with metals, release one of the unions that they have with hydrogens, it is because in reactions they release hydrogens.
Answer:
B.
Explanation:
Elemental analysis involves the actual percentage compositions of each element in the sample of the compounds. We know that there are two different compounds here that both contain copper and oxygen. What we don't know is the actual number of copper or oxygen composed in the compounds.
An elemental composition of these compounds would thus tell us this and will give an idea of the chemical formula of each since we now know quite well the percentage composition of each of these elements
Answer:
.997 atm
Explanation:
1. Find the combined gas law formula...
(P1V1/T1 = P2V2/T2)
2. Find our numbers...
P1= .982 atm
P2= ? (trying to find)
V1= 2 L
V2= 1.8 L
T1= 22 C = 295 K
T2= -3 C = 270 K
- Note: always use Kelvin. To find Kelving add 273 to ___C.
3. Rearrange formula to fit problem...
(P2=P1V1T2/V2T1)
4. Fill in our values...
P2= .982 atm x 2 L x 270 K / 1.8 L x 295 K
5. Do the math and your answer should be...
.997 atm

Answer: 
Explanation:
General representation of an element is given as: 
where,
Z represents Atomic number
A represents Mass number
X represents the symbol of an element
Beta decay : In this process, a neutron gets converted into a proton and an electron releasing a beta-particle. The beta particle released carries a charge of -1 units.
The given reaction would be represented as:
Answer:
Training officers in how to properly collect evidence
Explanation:
Forensic science is an interesting branch of science that involves the use of scientific procedures to solve a crime case. It encompasses collection of physical evidence from the crime scene and analyzing it in a laboratory using scientific means.
A forensic scientist is the individual in charge of performing these scientific procedures. His/her major role is to run the scientific analysis of the physical evidence brought in by the officers, however, he/she can also perform the task of training officers in how to properly collect evidence, in order not to damage the evidence or render it invalid for use.
