1. What types of evidence might be found at a bomb scene that could help

Chemistry
1 answer:
just olya [345]4 years ago
5 0

Answer:

Substances used to make the bomb

The area it was placed

Which people were in that area

How the bomb was set off

Explanation:

Examining the residues left at the scene by the bomb could tell forensics what the bomb was made out of, and the police could investigate possible leads about people who purchased (or have access to) such materials.

The area should give clues because security cameras could be used to trace who was there that should not be. There would be a possible suspect.

If it is a public place, then we can see if there is anyone of importance (to the suspect) that was there at that time.

If a remote detonator was used to set off the bomb, then the suspect would have to be relatively close to the bomb.

what is the molecular formula of benzoyl peroxide (c7h5o2) of the molecular mass is 0.242 kg/mol?(show work please)
AfilCa [17]

Answer : The molecular formula of benzoyl peroxide is C_{14}H_{10}O_4

Explanation :

Empirical formula : It is the simplest form of the chemical formula which depicts the whole number of atoms of each element present in the compound.  

Molecular formula : it is the chemical formula which depicts the actual number of atoms of each element present in the compound.  

For determining the molecular formula, we need to determine the valency which is multiplied by each element to get the molecular formula.

The equation used to calculate the valency is :

n=\frac{\text{Molecular mass}}{\text{Empirical mass}}

As we are given that the molar mass of compound is, 0.242 kg/mol.

Molecular mass = 0.242 kg/mol = 242 g/mol      (1 kg = 1000 g)

The empirical mass of C_7H_5O_2 = 7(12) + 5(1) + 2(16) = 121 g/eq

n=\frac{\text{Molecular mass}}{\text{Empirical mass}}

n=\frac{242}{121}

n=2

Molecular formula = (C_7H_5O_2)_n = (C_7H_5O_2)_2 = C_{14}H_{10}O_4

Thus, the molecular formula of benzoyl peroxide is C_{14}H_{10}O_4
