This is what i wrote in my notebook: (for AgNO3)
<span>Health Hazards Acute and Chronic: ACUTE:
INHALATION - MAY CAUSE SEVERE
IRRITATION TO MUCOUS MEMBRANES.
SKIN - MAY CAUSE SEVERE IRRITATION.
EYE - MAY CAUSE SEVERE IRRITATION.
CHRONIC: INHALATION, SKIN &
INGESTION - MAY CAUSE ARSYRIA.
Explanation of Carcinogenicity:THIS COMPOUND CONTAINS NO INGREDIENTS AT

Answer:
There are 
electrons in this atom.
Explanation:
Electron configuration of this atom: 
.
The electron orbitals of an atom are denoted as 
, 
, 
, 
, 
, etc. At any given time, an electron in this atom is located in exactly one orbital.
The electron configuration of an atom gives the number of electrons in each orbitals of this atom.
For example, in this atom, the superscript "
" on the right of "" means that there are two electrons in the 
orbital of this atom. Hence, would translate to:
- The orbital of this atom contains electrons.
- The orbital of this atom contains electrons.
- The orbitals of this atom contain
electrons.
Hence, there would be 
electrons in total in this atom.
Answer:
615 g
Explanation:
In order to convert from moles of any given substance into grams, we have to use said substance's <em>molar mass</em>, as follows:
- # moles * Molar mass = grams of substance.
Thus, we now <u>calculate the molar mass of beryllium iodide</u>, BeI₂, using the <em>molar masses of the elements</em>:
- Molar Mass of BeI₂ = Molar Mass of Be + (Molar Mass of I)*2 = 262.821 g/mol
Finally we <u>calculate how many grams are there in 2.34 moles of BeI₂</u>:
- 2.34 mol * 262.821 g/mol = 615 g
Answer:
I think the answer is B or Compounds
