Answer:
See the answer below.
Explanation:
Fire has three major components:
- Heat
- Smoke
- Gases ( in form of CO, CO2 etc)
If the victim had died as a result of the fire, he/he would have inhaled smoke and hot gases from the fire. These components would have resulted in traces of burns and soot deposition in the trachea and lungs as well as traces of CO in the blood of the victim.
If the analysis of the victim's corpse does not reflect some of the results above, it can be effectively concluded that the victim has been dead before the fire.
<em>The single most important indicator of death by the fire would be the presence of CO in the blood of the victim's corpse. All others might be to a less significant degrees.</em>

Answer:
1.03M
Explanation:
mass/molar mass = moles of solution
50 g / (80+1) = 0.617 mol HBr
molarity*volume = moles
M*0.600 L = 0.617 mol
M = 0.617/0.600 = 1.03 M
Answer:
Metalloids have properties of metals and non-metals.
Explanation:
A metalloid is a type of chemical element which has properties in between, or that are a mixture of, those of metals and nonmetals.
The six commonly recognized metalloids are boron, silicon, germanium, arsenic, antimony, and tellurium.
Metalloids have a metallic appearance, but they are brittle (nonmetal property) and only fair conductors of electricity. Chemically, they behave mostly as nonmetals. They can form alloys with metal.
Most of their other physical properties and chemical properties are intermediate in nature.
That means Metalloids have properties of both metal and nonmetal.
